Service Automates Boobytrapping of Hacked Sites

Hardly a week goes by without news of some widespread compromise in which thousands of Web sites that share a common vulnerability are hacked and seeded with malware. Media coverage of these mass hacks usually centers on the security flaw that allowed the intrusions, but one aspect of these crimes that’s seldom examined is the method by which attackers automate the booby-trapping and maintenance of their hijacked sites.

Regular readers of this blog may be unsurprised to learn that this is another aspect of the cybercriminal economy that can be outsourced to third-party services. Often known as “iFramers,” such services can simplify the task of managing large numbers of hacked sites that are used to drive traffic to sites that serve up malware and browser exploits.

At the very least, a decent iFramer service will allow customers to verify large lists of file transfer protocol (FTP) credentials used to administer hacked Web sites, scrubbing those lists of invalid credential pairs. The service will then upload the customer’s malware and malicious scripts to the hacked site, and check each link to ensure the trap is properly set.

A huge percentage of malware in the wild today has the built-in ability to steal FTP credentials from infected PCs. This is possible because people who administer Web sites often use FTP software to upload files and images, and allow those programs to store their FTP passwords. Thus, many modern malware variants will simply search for popular FTP programs on the victim’s system and extract any stored credentials.
