Facebook Malware threat
In yet another method for cyber criminals to utilize the world’s most popular social networks for their own nefarious purposes, it appears a trojan is circulating through Facebook, stealing accounts and (probably) taking creds.
Thanks to the vigilant mind of Malwarebytes User, Showbizz, we were able to take a look at this new threat and what it could mean for the rest of the net.
Here is how it works:
- User gets a Facebook instant message from a friend of their’s, which includes the words ‘lol’ and a file waiting to be downloaded.
- The user downloads the file because they can assume it can be trusted. The filename matches the usual filename of a photo: ‘IMG_xxxx’.zip.
- Once downloaded, the user unzips the file and clicks on what they assume is an image file, still called IMG_xxxx.jar
- The JAR file executes, downloads malware and infects the system.
- The infected users Facebook account is compromised and then used to send more malware to the users friends.
Unlike previous versions of this scam, it is almost like the cyber criminals decided to make an amalgam of different infection tactics to obtain the normal goal.
The first is the use of instant messaging, we have seen plenty of malware use instant messaging in various forms to send malicious files to victims, including Skype, MSN, Yahoo, etc.
