Half of Fortune 500s, US Agencies Still Infected With DNSChanger Trojan 112

tsu doh nimh writes "Two months after authorities shut down a massive Internet traffic hijacking scheme, the malicious software that powered the criminal network is still running on computers at half of the Fortune 500 companies, and on PCs at nearly 50 percent of all federal government agencies. Internet Identity, a Tacoma, Wash. company that sells security services, found evidence of at least one DNSChanger infection in computers at half of all Fortune 500 firms, and 27 out of 55 major government entities. Computers still infected with DNSChanger are up against a countdown clock. As part of the DNSChanger botnet takedown, the feds secured a court order to replace the Trojan's DNS infrastructure with surrogate, legitimate DNS servers. But those servers are only allowed to operate until March 8, 2012. Unless the court extends that order, any computers still infected with DNSChanger may no longer be able to browse the Web. The FBI is currently debating whether to extend the deadline or let it expire."

      Unfortunately, proving that you are better than a company's security staff often involves committing a crime, which looks bad when you are applying for a job later in life. Not everyone can be an independent consultant like Kevin Mitnick.

            Your first few jobs are payment after proving what you can do. They put a special file on the server. They pay you if you can produce the file for them. After they pay you, you tell them what you did and how to fix it.

      Actually, if you think about it, the crackers have a much much easier time of it. They only have to find one security issue. The people in IT have to try and cover ALL security issues. Never mind the fact that it's impossible to cover all security issues, because IT staff don't always have access to source code, are not always expert programmers, and don't necessarily know the best security practices for all programming languages.

      You're right. The only way that most of these companies or government agencies will even realize that they are infected/affected will be when some of their PC's stop working properly.

      • In my experience, they'll just poke at the non-functioning systems until they do something that makes them work again. Or until they run out of ideas and blame the "network card" or something and replace the hardware.

        If they don't know that they're infected by now, they don't have the expertise (basic knowledge) to monitor their own systems.

        They will just say "yep, that happens to computers sometimes" and move on. Never understanding that there is a huge hole in their security practices.

        • I'd recommend installing a different Trojan that points to another set of DNS-servers :) If you install an advanced trojan it should be able to keep out the competition as well, likely improving user experience on the computer.

          Of course, the trade off may not be to their liking :)

      Just re-configure the surrogate DNS servers to return the same reply to every query and point all traffic towards an FBI server hosting a web page that explains what's happened and why they are seeing the web page they are. May as well make mention of the fact that the DoJ has apparently been sending out email notifications followed up with snail mail version of these infections to the designated WHOIS abuse/tech contacts for IP ranges showing infected hosts, just in case they hadn't already figured it out for themselves. I don't think it'll take too long before someone in senior management figures out what that implies and goes for a walk over to the IT department with a clue-by-four.

      They should have shut it down in the first place. It's wildly irresponsible and stupid for the FBI to have set up a replacement infrastructure.

      Presumably the hosts that are compromised had a vulnerability. Leaving a working infrastructure in place has masked the signal not only that DNSChanger was installed, but that there might be an unpatched vulnerability. If they'd shut it down, staff would have looked at the boxes and identified that there was malware installed, then cleaned up the boxes in the process and fixed their patching process. Who knows what additional malware may have been installed in the interim using the same or other unpatched vulnerabilities, because the FBI meddled?

      In addition, by taking the responsibility for maintaining a DNS infrastructure, they run the risk of contributing to another mass compromise if the replacement infrastructure is itself compromised or becomes the victim of a cache poisoning attack.
