The Free Software Foundation's services face "ongoing (and increasing) distributed denial of service (DDoS) attacks," senior systems administrator Ian Kelling wrote Wednesday. But "Even though we are under active attack, gnu.org, ftp.gnu.org, and savannah.gnu.org are up with normal response times at the moment, and have been for the majority of this week, largely thanks to hard work from the Savannah hackers Bob, Corwin, and Luke who've helped us, your sysadmins."

"We've shielded these sites for almost a full year of intense attacks now, and we'll keep on fighting these attacks for as long as they continue." Our infrastructure has been under attack since August 2024. Large Language Model (LLM) web crawlers have been a significant source of the attacks, and as for the rest, we don't expect to ever know what kind of entity is targeting our sites or why.

- In the fall Bulletin, we wrote about the August attack on gnu.org. That attack continues, but we have mitigated it. Judging from the pattern and scope, the goal was likely to take the site down and it was not an LLM crawler. We do not know who or what is behind the attack, but since then, we have had more attacks with even higher severity.

- To begin with, GNU Savannah, the FSF's collaborative software development system, was hit by a massive botnet controlling about five million IPs starting in January. As of this writing, the attack is still ongoing, but the botnet's current iteration is mitigated. The goal is likely to build an LLM training dataset. We do not know who or what is behind this.

- Furthermore, gnu.org and ftp.gnu.org were targets in a new DDoS attack starting on May 27, 2025. Its goal seems to be to take the site down. It is currently mitigated. It has had several iterations, and each has caused some hours of downtime while we figured out how to defend ourselves against it. Here again, the goal was likely to take our sites down and we do not know who or what is behind this.

- In addition, directory.fsf.org, the server behind the Free Software Directory, has been under attack since June 18. This likely is an LLM scraper designed to specifically target Media Wiki sites with a botnet. This attack is very active and now partially mitigated...

Even though we are under active attack, gnu.org, ftp.gnu.org, and savannah.gnu.org are up with normal response times at the moment, and have been for the majority of this week, largely thanks to hard work from the Savannah hackers Bob, Corwin, and Luke who've helped us, your sysadmins. We've shielded these sites for almost a full year of intense attacks now, and we'll keep on fighting these attacks for as long as they continue.
The full-time FSF tech staff is just two systems administrators, "and we currently lack the funds to hire more tech staff any time soon," Kelling points out. Kelling titled his post "our small team vs millions of bots," suggesting that supporters purchase FSF memberships "to improve our staffing situation... Can you join us in our crucial work to guard user freedom and defy dystopia?"

Kelling also points out they're also facing "run-of-the-mill standard crawlers, SEO crawlers, crawlers pretending to be normal users, crawlers pretending to be other crawlers, uptime systems, vulnerability scanners, carrier-grade network address translation, VPNs, and normal browsers hitting our sites..."

"Some of the abuse is not unique to us, and it seems that the health of the web has some serious problems right now."

An anonymous reader quotes a report from Ars Technica: Large-scale attacks designed to bring down Internet services by sending them more traffic than they can process keep getting bigger, with the largest one yet, measured at 7.3 terabits per second, being reported Friday by Internet security and performance provider Cloudflare. The 7.3Tbps attack amounted to 37.4 terabytes of junk traffic that hit the target in just 45 seconds. That's an almost incomprehensible amount of data, equivalent to more than 9,300 full-length HD movies or 7,500 hours of HD streaming content in well under a minute.

Cloudflare said the attackers "carpet bombed" an average of nearly 22,000 destination ports of a single IP address belonging to the target, identified only as a Cloudflare customer. A total of 34,500 ports were targeted, indicating the thoroughness and well-engineered nature of the attack. [...] Cloudflare said the record DDoS exploited various reflection or amplification vectors, including the previously mentioned Network Time Protocol; the Quote of the Day Protocol, which listens on UDP port 17 and responds with a short quote or message; the Echo Protocol, which responds with the same data it receives; and Portmapper services used identify resources available to applications connecting through the Remote Procedure Call. Cloudflare said the attack was also delivered through one or more Mirai-based botnets. Such botnets are typically made up of home and small office routers, web cameras, and other Internet of Things devices that have been compromised.

An anonymous reader quotes a report from BleepingComputer: The FBI is warning that the BADBOX 2.0 malware campaign has infected over 1 million home Internet-connected devices, converting consumer electronics into residential proxies that are used for malicious activity. The BADBOX botnet is commonly found on Chinese Android-based smart TVs, streaming boxes, projectors, tablets, and other Internet of Things (IoT) devices. "The BADBOX 2.0 botnet consists of millions of infected devices and maintains numerous backdoors to proxy services that cyber criminal actors exploit by either selling or providing free access to compromised home networks to be used for various criminal activity," warns the FBI.

These devices come preloaded with the BADBOX 2.0 malware botnet or become infected after installing firmware updates and through malicious Android applications that sneak onto Google Play and third-party app stores. "Cyber criminals gain unauthorized access to home networks by either configuring the product with malicious software prior to the users purchase or infecting the device as it downloads required applications that contain backdoors, usually during the set-up process," explains the FBI. "Once these compromised IoT devices are connected to home networks, the infected devices are susceptible to becoming part of the BADBOX 2.0 botnet and residential proxy services4 known to be used for malicious activity."

Once infected, the devices connect to the attacker's command and control (C2) servers, where they receive commands to execute on the compromised devices, such as [routing malicious traffic through residential IPs to obscure cybercriminal activity, performing background ad fraud to generate revenue, and launching credential-stuffing attacks using stolen login data]. Over the years, the malware botnet continued expanding until 2024, when Germany's cybersecurity agency disrupted the botnet in the country by sinkholing the communication between infected devices and the attacker's infrastructure, effectively rendering the malware useless. However, that did not stop the threat actors, with researchers saying they found the malware installed on 192,000 devices a week later. Even more concerning, the malware was found on more mainstream brands, like Yandex TVs and Hisense smartphones. Unfortunately, despite the previous disruption, the botnet continued to grow, with HUMAN's Satori Threat Intelligence stating that over 1 million consumer devices had become infected by March 2025. This new larger botnet is now being called BADBOX 2.0 to indicate a new tracking of the malware campaign. "This scheme impacted more than 1 million consumer devices. Devices connected to the BADBOX 2.0 operation included lower-price-point, 'off brand,' uncertified tablets, connected TV (CTV) boxes, digital projectors, and more," explains HUMAN.

"The infected devices are Android Open Source Project devices, not Android TV OS devices or Play Protect certified Android devices. All of these devices are manufactured in mainland China and shipped globally; indeed, HUMAN observed BADBOX 2.0-associated traffic from 222 countries and territories worldwide."

An anonymous reader quotes a report from SC Media: Thousands of ASUS routers have been compromised with malware-free backdoors in an ongoing campaign to potentially build a future botnet, GreyNoise reported Wednesday. The threat actors abuse security vulnerabilities and legitimate router features to establish persistent access without the use of malware, and these backdoors survive both reboots and firmware updates, making them difficult to remove.

The attacks, which researchers suspect are conducted by highly sophisticated threat actors, were first detected by GreyNoise's AI-powered Sift tool in mid-March and disclosed Thursday after coordination with government officials and industry partners. Sekoia.io also reported the compromise of thousands of ASUS routers in their investigation of a broader campaign, dubbed ViciousTrap, in which edge devices from other brands were also compromised to create a honeypot network. Sekoia.io found that the ASUS routers were not used to create honeypots, and that the threat actors gained SSH access using the same port, TCP/53282, identified by GreyNoise in their report. The backdoor campaign affects multiple ASUS router models, including the RT-AC3200, RT-AC3100, GT-AC2900, and Lyra Mini.

GreyNoise advises users to perform a full factory reset and manually reconfigure any potentially compromised device. To identify a breach, users should check for SSH access on TCP port 53282 and inspect the authorized_keys file for unauthorized entries.

KrebsOnSecurity was hit with a near-record 6.3 Tbps DDoS attack, believed to be a test of the powerful new Aisuru IoT botnet. The attack, lasting under a minute, was the largest Google has ever mitigated and is linked to a DDoS-for-hire operation run by a 21-year-old Brazilian known as "Forky." Brian Krebs writes: [Google Security Engineer Damian Menscher] said the attack on KrebsOnSecurity lasted less than a minute, hurling large UDP data packets at random ports at a rate of approximately 585 million data packets per second. "It was the type of attack normally designed to overwhelm network links," Menscher said, referring to the throughput connections between and among various Internet service providers (ISPs). "For most companies, this size of attack would kill them." [...]

The 6.3 Tbps attack last week caused no visible disruption to this site, in part because it was so brief -- lasting approximately 45 seconds. DDoS attacks of such magnitude and brevity typically are produced when botnet operators wish to test or demonstrate their firepower for the benefit of potential buyers. Indeed, Google's Menscher said it is likely that both the May 12 attack and the slightly larger 6.5 Tbps attack against Cloudflare last month were simply tests of the same botnet's capabilities. In many ways, the threat posed by the Aisuru/Airashi botnet is reminiscent of Mirai, an innovative IoT malware strain that emerged in the summer of 2016 and successfully out-competed virtually all other IoT malware strains in existence at the time.

An anonymous reader quotes a report from BleepingComputer: Law enforcement authorities have dismantled a botnet that infected thousands of routers over the last 20 years to build two networks of residential proxies known as Anyproxy and 5socks. The U.S. Justice Department also indicted three Russian nationals (Alexey Viktorovich Chertkov, Kirill Vladimirovich Morozov, and Aleksandr Aleksandrovich Shishkin) and a Kazakhstani (Dmitriy Rubtsov) for their involvement in operating, maintaining, and profiting from these two illegal services.

During this joint action dubbed 'Operation Moonlander,' U.S. authorities worked with prosecutors and investigators from the Dutch National Police, the Netherlands Public Prosecution Service (Openbaar Ministerie), and the Royal Thai Police, as well as analysts with Lumen Technologies' Black Lotus Labs. Court documents show that the now-dismantled botnet infected older wireless internet routers worldwide with malware since at least 2004, allowing unauthorized access to compromised devices to be sold as proxy servers on Anyproxy.net and 5socks.net. The two domains were managed by a Virginia-based company and hosted on servers globally.

On Wednesday, the FBI also issued a flash advisory (PDF) and a public service announcement warning that this botnet was targeting patch end-of-life (EoL) routers with a variant of the TheMoon malware. The FBI warned that the attackers are installing proxies later used to evade detection during cybercrime-for-hire activities, cryptocurrency theft attacks, and other illegal operations. The list of devices commonly targeted by the botnet includes Linksys and Cisco router models, including:

- Linksys E1200, E2500, E1000, E4200, E1500, E300, E3200, E1550
- Linksys WRT320N, WRT310N, WRT610N
- Cisco M10 and Cradlepoint E100 "The botnet controllers require cryptocurrency for payment. Users are allowed to connect directly with proxies using no authentication, which, as documented in previous cases, can lead to a broad spectrum of malicious actors gaining free access," Black Lotus Labs said. "Given the source range, only around 10% are detected as malicious in popular tools such as VirusTotal, meaning they consistently avoid network monitoring tools with a high degree of success. Proxies such as this are designed to help conceal a range of illicit pursuits including ad fraud, DDoS attacks, brute forcing, or exploiting victim's data."

An anonymous reader quotes a report from Ars Technica: A technique that hostile nation-states and financially motivated ransomware groups are using to hide their operations poses a threat to critical infrastructure and national security, the National Security Agency has warned. The technique is known as fast flux. It allows decentralized networks operated by threat actors to hide their infrastructure and survive takedown attempts that would otherwise succeed. Fast flux works by cycling through a range of IP addresses and domain names that these botnets use to connect to the Internet. In some cases, IPs and domain names change every day or two; in other cases, they change almost hourly. The constant flux complicates the task of isolating the true origin of the infrastructure. It also provides redundancy. By the time defenders block one address or domain, new ones have already been assigned.

"This technique poses a significant threat to national security, enabling malicious cyber actors to consistently evade detection," the NSA, FBI, and their counterparts from Canada, Australia, and New Zealand warned Thursday. "Malicious cyber actors, including cybercriminals and nation-state actors, use fast flux to obfuscate the locations of malicious servers by rapidly changing Domain Name System (DNS) records. Additionally, they can create resilient, highly available command and control (C2) infrastructure, concealing their subsequent malicious operations." There are two variations of fast flux described in the advisory: single flux and double flux. Single flux involves mapping a single domain to a rotating pool of IP addresses using DNS A (IPv4) or AAAA (IPv6) records. This constant cycling makes it difficult for defenders to track or block the associated malicious servers since the addresses change frequently, yet the domain name remains consistent.

Double flux takes this a step further by also rotating the DNS name servers themselves. In addition to changing the IP addresses of the domain, it cycles through the name servers using NS (Name Server) and CNAME (Canonical Name) records. This adds an additional layer of obfuscation and resilience, complicating takedown efforts.

"A key means for achieving this is the use of Wildcard DNS records," notes Ars. "These records define zones within the Domain Name System, which map domains to IP addresses. The wildcards cause DNS lookups for subdomains that do not exist, specifically by tying MX (mail exchange) records used to designate mail servers. The result is the assignment of an attacker IP to a subdomain such as malicious.example.com, even though it doesn't exist." Both methods typically rely on large botnets of compromised devices acting as proxies, making it challenging for defenders to trace or disrupt the malicious activity.

The Ballista botnet is actively exploiting a high-severity remote code execution flaw (CVE-2023-1389) in TP-Link Archer AX-21 routers, infecting over 6,000 devices primarily in Brazil, Poland, the UK, Bulgaria, and Turkey. Tom's Hardware reports: According to a new report from the Cato CTRL team, the Ballista botnet exploits a remote code execution vulnerability that directly impacts the TP-Link Archer AX-21 router. The botnet can lead to command injection which then makes remote code execution (RCE) possible so that the malware can spread itself across the internet automatically. This high severity security flaw (tracked as CVE-2023-1389) has also been used to spread other malware families as far back as April 2023 when it was used in the Mirai botnet malware attacks. The flaw also linked to the Condi and AndroxGh0st malware attacks.

Ballista's most recent exploitation attempt was February 17, 2025 and Cato CTRL first detected it on January 10, 2025. Of the thousands of infected devices, the majority of them are concentrated in Brazil, Poland, the United Kingdom, Bulgaria and Turkey; with the botnet targeting manufacturing, medical/healthcare, services and technology organizations in the United States, Australia, China and Mexico.

A survey of 2,130 Americans has revealed widespread vulnerability to cyber attacks through unsupported smart devices, with 43% unaware their devices might lose software support. The security threat was underscored in December 2023 when U.S. authorities disrupted a Chinese state-sponsored botnet targeting home routers and cameras that had stopped receiving security updates. Cloudflare separately reported a record-breaking DDoS attack in late 2023, primarily originating from compromised smart TVs and set-top boxes.

The survey, conduced by Consumer Reports, found that only 39% of consumers learned about lost software support from manufacturers, with most discovering issues when devices stopped working (40%) or through media reports (15%). Most consumers expect their smart devices to retain functionality after losing software support, particularly for large appliances (70%). However, Consumer Reports' research found only 14% of 21 smart appliance brands specify support timeframes, while an FTC study of 184 devices showed just 11% disclose support duration.

Remember that massive botnet run by Chinese government hackers? Flax Typhoon "compromised computer networks in North America, Europe, Africa, and across Asia, with a particular focus on Taiwan," according to the U.S. Treasury Department. (The group's botnet breaching this autumn affected "at least 260,000 internet-connected devices," reports the Washington Post, "roughly half of which were located in the United States.")

Friday America's Treasury Department sanctioned "a Beijing-based cybersecurity company for its role in multiple computer intrusion incidents against U.S. victims..." according to an announcement from the department's Office of Foreign Assets Control. "Between summer 2022 and fall 2023, Flax Typhoon actors used infrastructure tied to Integrity Tech during their computer network exploitation activities against multiple victims. During that time, Flax Typhoon routinely sent and received information from Integrity Tech infrastructure."

From the Washington Post: The group behind the attacks was active since at least 2021, but U.S. authorities only managed to wrest control of the devices from the hackers in September, after the FBI won a court order that allowed the agency to send commands to the infected devices...

Treasury's designation follows sanctions announced last month on Sichuan Silence Information Technology Company, in which U.S. officials accused the company of exploiting technology flaws to install malware in more than 80,000 firewalls, including those protecting U.S. critical infrastructure. The new sanctions on Beijing Integrity Technology are notable due to the company's public profile and outsize role in servicing China's police and intelligence services via state-run hacking competitions. The company, which is listed in Shanghai and has a market capitalization of more than $327 million, plays a central role in providing state agencies "cyber ranges" — technology that allows them to simulate cyberattacks and defenses...

In September, FBI Director Christopher A. Wray said the Flax Typhoon attack successfully infiltrated universities, media organizations, corporations and government agencies, and in some cases caused significant financial losses as groups raced to replace the infected hardware. He said at the time that the operation to shut down the network was "one round in a much longer fight...." A 2024 assessment by the Office of the Director of National Intelligence said China is the most "active and persistent" cyberthreat and that actors under Beijing's direction have made efforts to breach U.S. critical infrastructure with the intention of lying in wait to be able to launch attacks in the event of major conflict.
"The Treasury sanctions bar Beijing Integrity Technology from access to U.S. financial systems and freeze any assets the company might hold in the United States," according to the article, "but the moves are unlikely to have a significant effect on the company," (according to Dakota Cary, a fellow at the Atlantic Council who has studied the company's role in state-sponsored hacking).

"A cyberattack tied to the Chinese government penetrated the networks of a swath of U.S. broadband providers," reports the Wall Street Journal, "potentially accessing information from systems the federal government uses for court-authorized network wiretapping requests.

"For months or longer, the hackers might have held access to network infrastructure used to cooperate with lawful U.S. requests for communications data, according to people familiar with the matter, which amounts to a major national security risk." The attackers also had access to other tranches of more generic internet traffic, they said. Verizon Communications, AT&T and Lumen Technologies are among the companies whose networks were breached by the recently discovered intrusion, the people said.

The widespread compromise is considered a potentially catastrophic security breach and was carried out by a sophisticated Chinese hacking group dubbed Salt Typhoon. It appeared to be geared toward intelligence collection, the people said... The surveillance systems believed to be at issue are used to cooperate with requests for domestic information related to criminal and national security investigations. Under federal law, telecommunications and broadband companies must allow authorities to intercept electronic information pursuant to a court order. It couldn't be determined if systems that support foreign intelligence surveillance were also vulnerable in the breach...

The hackers appear to have engaged in a vast collection of internet traffic from internet service providers that count businesses large and small, and millions of Americans, as their customers. Additionally, there are indications that the hacking campaign targeted a small number of service providers outside the U.S., the people said. A person familiar with the attack said the U.S. government considered the intrusions to be historically significant and worrisome... "It will take time to unravel how bad this is, but in the meantime it's the most significant in a long string of wake-up calls that show how the PRC has stepped up their cyber game," said Brandon Wales, former executive director at the Cybersecurity and Infrastructure Security Agency and now a vice president at SentinelOne, referring to the People's Republic of China. "If companies and governments weren't taking this seriously before, they absolutely need to now."
Three weeks ago TechCrunch also reported that the FBI "took control of a botnet made up of hundreds of thousands of internet-connected devices, such as cameras, video recorders, storage devices, and routers, which was run by a Chinese government hacking group, FBI director Christopher Wray and U.S. government agencies revealed Wednesday.

Ars Technica's Dan Goodin reports: Five years ago, researchers made a grim discovery -- a legitimate Android app in the Google Play market that was surreptitiously made malicious by a library the developers used to earn advertising revenue. With that, the app was infected with code that caused 100 million infected devices to connect to attacker-controlled servers and download secret payloads. Now, history is repeating itself. Researchers from the same Moscow, Russia-based security firm reported Monday that they found two new apps, downloaded from Play 11 million times, that were infected with the same malware family. The researchers, from Kaspersky, believe a malicious software developer kit for integrating advertising capabilities is once again responsible. [...]

The researchers found Necro in two Google Play apps. One was Wuta Camera, an app with 10 million downloads to date. Wuta Camera versions 6.3.2.148 through 6.3.6.148 contained the malicious SDK that infects apps. The app has since been updated to remove the malicious component. A separate app with roughly 1 million downloads -- known as Max Browser -- was also infected. That app is no longer available in Google Play. The researchers also found Necro infecting a variety of Android apps available in alternative marketplaces. Those apps typically billed themselves as modified versions of legitimate apps such as Spotify, Minecraft, WhatsApp, Stumble Guys, Car Parking Multiplayer, and Melon Sandbox. People who are concerned they may be infected by Necro should check their devices for the presence of indicators of compromise listed at the end of this writeup.

An anonymous reader shares a report: Last week, the FBI took control of a botnet made up of hundreds of thousands of internet-connected devices, such as cameras, video recorders, storage devices, and routers, which was run by a Chinese government hacking group, FBI director Christopher Wray and U.S. government agencies revealed Wednesday. The hacking group, dubbed Flax Typhoon, was "targeting critical infrastructure across the U.S. and overseas, everyone from corporations and media organizations to universities and government agencies," Wray said at the Aspen Cyber Summit cybersecurity conference on Wednesday.

"But working in collaboration with our partners, we executed court-authorized operations to take control of the botnet's infrastructure," Wray said, explaining that once the authorities did that, the FBI also removed the malware from the compromised devices. "Now, when the bad guys realized what was happening, they tried to migrate their bots to new servers and even conducted a [Distributed Denial of Service] attack against us."

An anonymous reader quotes a report from KrebsOnSecurity: The U.S. Department of the Treasury today unveiled sanctions against three Chinese nationals for allegedly operating 911 S5, an online anonymity service that for many years was the easiest and cheapest way to route one's Web traffic through malware-infected computers around the globe. KrebsOnSecurity identified one of the three men in a July 2022 investigation into 911 S5, which was massively hacked and then closed ten days later.

From 2015 to July 2022, 911 S5 sold access to hundreds of thousands of Microsoft Windows computers daily, as "proxies" that allowed customers to route their Internet traffic through PCs in virtually any country or city around the globe -- but predominantly in the United States. 911 built its proxy network mainly by offering "free" virtual private networking (VPN) services. 911's VPN performed largely as advertised for the user -- allowing them to surf the web anonymously -- but it also quietly turned the user's computer into a traffic relay for paying 911 S5 customers. 911 S5's reliability and extremely low prices quickly made it one of the most popular services among denizens of the cybercrime underground, and the service became almost shorthand for connecting to that "last mile" of cybercrime. Namely, the ability to route one's malicious traffic through a computer that is geographically close to the consumer whose stolen credit card is about to be used, or whose bank account is about to be emptied.

In July 2022, KrebsOnSecurity published a deep dive into 911 S5, which found the people operating this business had a history of encouraging the installation of their proxy malware by any means available. That included paying affiliates to distribute their proxy software by secretly bundling it with other software. That story named Yunhe Wang from Beijing as the apparent owner or manager of the 911 S5 proxy service. In today's Treasury action, Mr. Wang was named as the primary administrator of the botnet that powered 911 S5. Update, May 29, 12:26 p.m. ET: The U.S. Department of Justice (DOJ) just announced they have arrested Wang in connection with the 911 S5 botnet. The DOJ says 911 S5 customers have stolen billions of dollars from financial institutions, credit card issuers, and federal lending programs. [...] The third man sanctioned is Yanni Zheng, a Chinese national the U.S. Treasury says acted as an attorney for Wang and his firm -- Spicy Code Company Limited -- and helped to launder proceeds from the business into real estate holdings. Spicy Code Company was also sanctioned, as well as Wang-controlled properties Tulip Biz Pattaya Group Company Limited, and Lily Suites Company Limited. "911 S5 customers allegedly targeted certain pandemic relief programs," a DOJ statement on the arrest reads. "For example, the United States estimates that 560,000 fraudulent unemployment insurance claims originated from compromised IP addresses, resulting in a confirmed fraudulent loss exceeding $5.9 billion. Additionally, in evaluating suspected fraud loss to the Economic Injury Disaster Loan (EIDL) program, the United States estimates that more than 47,000 EIDL applications originated from IP addresses compromised by 911 S5. Millions of dollars more were similarly identified by financial institutions in the United States as loss originating from IP addresses compromised by 911 S5."

"Jingping Liu assisted Yunhe Wang by laundering criminally derived proceeds through bank accounts held in her name that were then utilized to purchase luxury real estate properties for Yunhe Wang," the document continues. "These individuals leveraged their malicious botnet technology to compromise personal devices, enabling cybercriminals to fraudulently secure economic assistance intended for those in need and to terrorize our citizens with bomb threats."

Jess Weatherbed reports via The Verge: Midjourney says it has banned Stability AI staffers from using its service, accusing employees at the rival generative AI company of causing a systems outage earlier this month during an attempt to scrape Midjourney's data. Midjourney posted an update to its Discord server on March 2nd that acknowledged an extended server outage was preventing generated images from appearing in user galleries. In a summary of a business update call on March 6th, Midjourney claimed that "botnet-like activity from paid accounts" -- which the company specifically links to Stability AI employees -- was behind the outage.

According to Midjourney user Nick St. Pierre on X, who listened to the call, Midjourney said that the service was brought down because "someone at Stability AI was trying to grab all the prompt and image pairs in the middle of a night on Saturday." St. Pierre said that Midjourney had linked multiple paid accounts to an individual on the Stability AI data team. In its summary of the business update call on March 6th (which Midjourney refers to as "office hours"), the company says it's banning all Stability AI employees from using its service "indefinitely" in response to the outage. Midjourney is also introducing a new policy that will similarly ban employees of any company that exercises "aggressive automation" or causes outages to the service.

St. Pierre flagged the accusations to Stability AI CEO Emad Mostaque, who replied on X, saying he was investigating the situation and that Stability hadn't ordered the actions in question. "Very confusing how 2 accounts would do this team also hasn't been scraping as we have been using synthetic & other data given SD3 outperforms all other models," said Mostaque, referring to the Stable Diffusion 3 AI model currently in preview. He claimed that if the outage was caused by a Stability employee, then it was unintentional and "obviously not a DDoS attack." Midjourney founder David Holz responded to Mostaque in the same thread, claiming to have sent him "some information" to help with his internal investigation.

An anonymous reader quotes a report from Ars Technica: The FBI and partners from 10 other countries are urging owners of Ubiquiti EdgeRouters to check their gear for signs they've been hacked and are being used to conceal ongoing malicious operations by Russian state hackers. The Ubiquiti EdgeRouters make an ideal hideout for hackers. The inexpensive gear, used in homes and small offices, runs a version of Linux that can host malware that surreptitiously runs behind the scenes. The hackers then use the routers to conduct their malicious activities. Rather than using infrastructure and IP addresses that are known to be hostile, the connections come from benign-appearing devices hosted by addresses with trustworthy reputations, allowing them to receive a green light from security defenses.

"In summary, with root access to compromised Ubiquiti EdgeRouters, APT28 actors have unfettered access to Linux-based operating systems to install tooling and to obfuscate their identity while conducting malicious campaigns," FBI officials wrote in an advisory Tuesday. APT28 -- one of the names used to track a group backed by the Russian General Staff Main Intelligence Directorate known as GRU -- has been doing just for at least the past four years, the FBI has alleged. Earlier this month, the FBI revealed that it had quietly removed Russian malware from routers in US homes and businesses. The operation, which received prior court authorization, went on to add firewall rules that would prevent APT28 -- also tracked under names including Sofacy Group, Forest Blizzard, Pawn Storm, Fancy Bear, and Sednit -- from being able to regain control of the devices.

On Tuesday, FBI officials noted that the operation only removed the malware used by APT28 and temporarily blocked the group using its infrastructure from reinfecting them. The move did nothing to patch any vulnerabilities in the routers or to remove weak or default credentials hackers could exploit to once again use the devices to surreptitiously host their malware. "The US Department of Justice, including the FBI, and international partners recently disrupted a GRU botnet consisting of such routers," they warned. "However, owners of relevant devices should take the remedial actions described below to ensure the long-term success of the disruption effort and to identify and remediate any similar compromises."

Those actions include:

- Perform a hardware factory reset to remove all malicious files
- Upgrade to the latest firmware version
- Change any default usernames and passwords
- Implement firewall rules to restrict outside access to remote management services

Connor Jones reports via The Register: A Ukrainian cybercrime kingpin who ran some of the most pervasive malware operations faces 40 years in prison after spending nearly a decade on the FBI's Cyber Most Wanted List. Vyacheslav Igorevich Penchukov, 37, pleaded guilty this week in the US to two charges related to his leadership role in both the Zeus and IcedID malware operations that netted millions of dollars in the process. Penchukov's plea will be seen as the latest big win for US law enforcement in its continued fight against cybercrime and those that enable it. However, authorities took their time getting him in 'cuffs. [...]

"Malware like IcedID bleeds billions from the American economy and puts our critical infrastructure and national security at risk," said US attorney Michael Easley for the eastern district of North Carolina. "The Justice Department and FBI Cyber Squad won't stand by and watch it happen, and won't quit coming for the world's most wanted cybercriminals, no matter where they are in the world. This operation removed a key player from one of the world's most notorious cybercriminal rings. Extradition is real. Anyone who infects American computers had better be prepared to answer to an American judge."

This week, he admitted one count of conspiracy to commit a racketeer influenced and corrupt organizations (RICO) act offense relating to Zeus, and one count of conspiracy to commit wire fraud in relation to IcedID. Each count carries a maximum sentence of 20 years. His sentencing date is set for May 9, 2024. Zeus malware, a banking trojan that formed a botnet for financial theft, caused over $100 million in losses before its 2014 dismantlement. Its successor, SpyEye, incorporated enhanced features for financial fraud. Despite the 2014 takedown of Zeus, Penchukov moved on to lead IcedID, a similar malware first found in 2017. IcedID evolved from banking fraud to ransomware, severely affecting the University of Vermont Medical Center in 2020 with over $30 million in damages.

An anonymous reader shares a report: More than 1,000 Ubiquiti routers in homes and small businesses were infected with malware used by Russian-backed agents to coordinate them into a botnet for crime and spy operations, according to the Justice Department. That malware, which worked as a botnet for the Russian hacking group Fancy Bear, was removed in January 2024 under a secret court order as part of "Operation Dying Ember," according to the FBI's director. It affected routers running Ubiquiti's EdgeOS, but only those that had not changed their default administrative password. Access to the routers allowed the hacking group to "conceal and otherwise enable a variety of crimes," the DOJ claims, including spearphishing and credential harvesting in the US and abroad.

Unlike previous attacks by Fancy Bear -- that the DOJ ties to GRU Military Unit 26165, which is also known as APT 28, Sofacy Group, and Sednit, among other monikers -- the Ubiquiti intrusion relied on a known malware, Moobot. Once infected by "Non-GRU cybercriminals," GRU agents installed "bespoke scripts and files" to connect and repurpose the devices, according to the DOJ. The DOJ also used the Moobot malware to copy and delete the botnet files and data, according to the DOJ, and then changed the routers' firewall rules to block remote management access. During the court-sanctioned intrusion, the DOJ "enabled temporary collection of non-content routing information" that would "expose GRU attempts to thwart the operation." This did not "impact the routers' normal functionality or collect legitimate user content information," the DOJ claims. "For the second time in two months, we've disrupted state-sponsored hackers from launching cyber-attacks behind the cover of compromised US routers," said Deputy Attorney General Lisa Monaco in a press release.

On Tuesday, The Independent, Tom's Hardware, and many other tech outlets reported on a story about how three million smart toothbrushes were used in a DDoS attack. The only problem? It "didn't actually happen," writes Jason Koebler via 404 Media. "There are no additional details about this apparent attack, and most of the article cites general research by a publicly traded cybersecurity company called Fortinet which has detected malicious, hijacked internet of things devices over the years. A search on Fortinet's website shows no recent published research about hacked smart toothbrushes." From the report: The original article, called "The toothbrushes are attacking," starts with the following passage: "She's at home in the bathroom, but she's part of a large-scale cyber attack. The electric toothbrush is programmed with Java, and criminals have unnoticed installed malware on it - like on 3 million other toothbrushes. One command is enough and the remote-controlled toothbrushes simultaneously access the website of a Swiss company. The site collapses and is paralyzed for four hours. Millions of dollars in damage is caused. This example, which seems like a Hollywood scenario, actually happened. It shows how versatile digital attacks have become." [...]

The "3 million hacked smart toothbrushes" story has now been viral for more than 24 hours and literally no new information about it has emerged despite widespread skepticism from people in the security industry and its virality. The two Fortinet executives cited in the original report did not respond to an email and LinkedIn message seeking clarification, and neither did Fortinet's PR team. The author of the Aargauer Zeitung story also did not respond to a request for more information. I called Fortinet's headquarters, asked to speak to the PR contact listed on the press release about its earnings, which was published after the toothbrush news began to go viral, and was promptly disconnected. The company has continued to tweet about other, unrelated things. They have not responded to BleepingComputer either, nor the many security researchers who are asking for further proof that this actually happened. While we don't know how this happened, Fortinet has been talking specifically about the dangers of internet-connected toothbrushes for years, and has been using it as an example in researcher talks. In a statement to 404 Media, Fortinet said "To clarify, the topic of toothbrushes being used for DDoS attacks was presented during an interview as an illustration of a given type of attack, and it is not based on research from Fortinet or FortiGuard Labs. It appears that due to translations the narrative on this topic has been stretched to the point where hypothetical and actual scenarios are blurred."

An anonymous reader quotes a report from Tom's Hardware: According to a recent report published by the Aargauer Zeitung (h/t Golem.de), around three million smart toothbrushes have been infected by hackers and enslaved into botnets. The source report says this sizable army of connected dental cleansing tools was used in a DDoS attack on a Swiss company's website. The firm's site collapsed under the strain of the attack, reportedly resulting in the loss of millions of Euros of business. In this particular case, the toothbrush botnet was thought to have been vulnerable due to its Java-based OS. No particular toothbrush brand was mentioned in the source report. Normally, the toothbrushes would have used their connectivity for tracking and improving user oral hygiene habits, but after a malware infection, these toothbrushes were press-ganged into a botnet.

Stefan Zuger from the Swiss branch of the global cybersecurity firm Fortinet provided the publication with a few tips on what people could do to protect their own toothbrushes -- or other connected gadgetry like routers, set-top boxes, surveillance cameras, doorbells, baby monitors, washing machines, and so on. "Every device that is connected to the Internet is a potential target -- or can be misused for an attack," Zuger told the Swiss newspaper. The security expert also explained that every connected device was being continually probed for vulnerabilities by hackers, so there is a real arms race between device software/firmware makers and cyber criminals. Fortinet recently connected an 'unprotected' PC to the internet and found it took only 20 minutes before it became malware-ridden. UPDATE 1/7/24: This attack "didn't actually happen," writes Jason Koebler via 404 Media. "There are no additional details about this apparent attack, and most of the article cites general research by a publicly traded cybersecurity company called Fortinet which has detected malicious, hijacked internet of things devices over the years. A search on Fortinet's website shows no recent published research about hacked smart toothbrushes."

The cybersecurity firm Fortinet said in a statement: "To clarify, the topic of toothbrushes being used for DDoS attacks was presented during an interview as an illustration of a given type of attack, and it is not based on research from Fortinet or FortiGuard Labs. It appears that due to translations the narrative on this topic has been stretched to the point where hypothetical and actual scenarios are blurred. FortiGuard Labs has not observed Mirai or other IoT botnets target toothbrushes or similar embedded devices."
