ESET, the specialist in proactive protection against Internet threats with a 20 year history, has discovered a social engineering trojan horse. The piece of malware was managed to steal the login credentials of more than 16,000 Facebook users.
ESET began studying the Trojan at the beginning of 2012. However, due to its proactive generic detection of this threat, the users of ESET security solutions were protected against it already from December 2011. During the investigation ESET could not provide any details about this threat publicly.
The attacker used the malware to gain the user's FB login credentials, his/her score in the game, as well as information on the amount of credit cards stored in his/her Facebook settings and available to increase the credit in the game of poker. The game had a functionality that allowed replenishing the chip value using real money by inputting the credit card details or PayPal account. To gain the user's login credentials, an army of 800 of computers were used - all infected and controlled by the attacker. These machines were executing commands from the C&C (Command & Control) server. The creator of the threat has launched an attack using the login credentials of several FB accounts, which were gained ahead of time.
"To protect against attacks relying on social engineering methods, having a good security solution is not enough, users should be attentive to \any such ploys," says Róbert Lipovský, ESET Security Intelligence Team Lead. He adds "The user could recognize the fake FB login page if he/she would check the site's URL."
The infected computers received a command to login into the user's FB accounts and to gain the user's Texas HoldEm score, as well as the amount of credit cards stored in his/her FB account. In case of a user without a credit card or low score, the infected computer received instructions to infect the victim's FB profile with a link to a phishing site. This site has acted to directly or indirectly lure the player's FB friends to a website resembling the FB homepage. In case the login credentials were input by them, they were also harvested by the attacker. While analyzing this botnet ESET estimates that the attacker could gain access to a total of 16,194 login credentials. ESET would like to caution that any other FB application could have been infected in this way, not just Texas HoldEm Poker.
The number of threats utilizing Facebook is rapidly growing. To counter this trend, ESET has introduced a security application ESET Social Media Scanner which is available free of charge and is capable of scanning the user's profile for the presence of malicious and phishing links. On top of that, the app can detect malicious links on the timeline of user's Facebook friends.
