Malicious code distributed through MySpace 
(17/07/2007)
Several malicious codes are using MySpace pages to spread. In some cases, these pages have not been specifically created to spread malware, but have been modified to serve this malicious purpose by exploiting a vulnerability or design flaw without the legitimate user knowing.
Most of these malicious codes are Trojans, like the dangerous FireByPass.BA, which captures confidential information entered or saved by users on computers. This and other Trojans found in MySpace use rootkit techniques to hide their processes, which makes them even more dangerous.
This is not the first time that MySpace has been used to spread malicious codes. The first attack against social networks started in 2005, when a MySpace user created a worm (MySpace.A) that allowed them to add a million entries to their contact list. This was, however, a low-danger infection.
The first attempt at causing a serious infection through MySpace took place towards the end of 2006, when a worm was created that used the network’s user profiles to spread. The worm infected everybody that visited a certain user profile.
Around that time, an advertising banner in MySpace exploited a Windows Metafile vulnerability to infect over a million users with spyware. Some days later, a worm was discovered at MySpace that inserted Java script in user profiles. When somebody tried to visit some of those profiles, they were redirected to a web page that blamed the U.S. government for the 9-11 attacks.
However, the most serious case took place at the end of 2006. The attackers exploited a feature of Apple’s QuickTime player to spread a worm in files that tried to pass themselves off as movies. Users that tried to view them became infected. In addition, the worm modified profile headers (which display the groups tab, forums tab, etc.) so that all of them pointed to a fraudulent website. This was a spoofed version of MySpace’s official site for stealing user names and passwords. This worm was also designed to send spam massively to all the contacts of infected users.
"Cyber-crooks want to distribute their creations to as many users as possible. That’s why they use networks that attract millions of Internet users around the world to spread their creations," explained Luis Corrons, Technical Director of PandaLabs.
