Gamers on the popular Steam gaming service have been targeted with phishing scams via the service’s popular Marketplace – with apparent ‘bargains’ offering a sting in the tail, according to CBR Online.
Gamers have been targeted with infected files via both Steams own Marketplace and trading sites such as CSGolounge.
The scam goes like this: a gamer will offer an in-game item for sale, and his victim will download an image file before purchase – except instead of the image of the in-game weapon they expect, they install a screensaver, which contains a nasty Trojan.
Look out for the screensaver and bargain weapon scams over at the steam marketplace.
