Online poker players are being cheated out of potential winnings thanks to a new form of malware discovered by security company, ESET.
Members of online gambling sites, PokerStars and Full Tilt Poker, have been targeted by a new malicious spyware program called Odlanor. The spyware, which takes screenshots of the infected player’s virtual poker hand, is designed to allow the malware operator to cheat during online games.
ESET said that, as of September 16, several hundred users have been infected with Win32/Spy.Odlanor. Malware researchers at ESET analysed the trojan, discovering that it is installed and activated on Windows systems in a number of ways.
ESET senior malware researcher, Robert Lipovsky, said the company had seen the trojan masquerading as a number of benign installers for various general purpose programs, such as Daemon Tools or uTorrent.
“In other cases, the spyware is installed through various poker-related programs,“ he said.
Once installed, the malware first checks if one or both the programs are running. If confirmed, Odlanor proceeds to take screenshots of the poker hand, all without alerting the victim.
The screenshots capture the player’s cards in the victim’s virtual hand and are sent to the attacker, giving the criminal an unfair advantage at winning.
