"When I woke up the next morning, I had four emails from Amazon AWS and a missed phone call from Amazon AWS. Something about 140 servers running on my AWS account. What? How? I only had S3 keys on my GitHub and they where gone within 5 minutes! Turns out through the S3 API you can actually spin up EC2 instances, and my key had been spotted by a bot that continually searches GitHub for API keys. Amazon AWS customer support informed me this happens a lot recently; hackers have created an algorithm that searches GitHub 24 hours per day for API keys. Once it finds one it spins up max instances of EC2 servers to farm itself bitcoins."
Researchers at IBM's X-Force research team have seen a new version of Cridex, which is also known as Bugat and Feodo, using some of the same techniques that GOZ used to such good effect. Specifically, the new strain of malware has adopted GOZ's penchant for using HTML injections, and the researchers say the technique is nearly identical to the way that GOZ handled it.
"There are two possible explanations for this. First, someone from the GOZ group could have moved to the Bugat team. This would not be the first time something like this has happened, which we've witnessed in other cases involving Zeus and Citadel; however, it is not very likely in this case since Bugat and GOZ are essentially competitors, while Zeus and Citadel are closely related. The second and more likely explanation is that the Bugat team could have analyzed and perhaps reversed the GOZ malware before copying the HTML injections that made GOZ so highly profitable for its operators," Etay Maor, a senior fraud prevention strategist at IBM, wrote in an analysis of the new malware.
