According to ESET security researcher Robert Lipovsky, there's evidence to suspect that "several hundred" gamblers on the Pokerstars and Full Tilt Poker platforms have been hit with a cheating trojan.

Lipovsky wrote: Every once in a while, though, we stumble upon something that stands out, something that doesn’t fall into the “common” malware categories that we encounter every day—such as ransomware, banking trojans, or targeted attacks (APTs)—just to name a few of those that are currently causing the most problems. Today, we’re bringing you one of those uncommon threats—a trojan devised to target players of online poker.

This latest bit of malware is called Odlanor and comes two years after ESET warned of the PokerAgent botnet propagating on Facebook in connection to the Zynga Poker app.

Once executed, the Odlanor malware will be used to create screenshots of the window of the two targeted poker clients—PokerStars or Full Tilt Poker, if the victim is running either of them. The screenshots are then sent to the attacker’s remote computer.

Afterwards, the screenshots can be retrieved by the cheating attacker. ESET found several versions of the malware dating back to March of this year.

ESET warns that "the trojan poses a potential threat to any player of online poker."
