...this month in MSRT was a very significant release for Gamers everywhere with the addition of a variety of password stealers directly targeting Online games. The main targets are mostly based in Eastern Asia (Lineage Online, Legend Of Mir, ZT Online just to name a few), but World of Warcraft and Valve’s Steam client are high on the hit-list too – you didn’t escape that easily.

The main offender in this motley crew of badness is Win32/Taterf. Taterf has been running hot the last few months, constituting over 80% of the April and May Wildlists. The worm itself is actually a mutation of Win32/Frethog, being based off the same source code. Frethog is just a drop in the ocean of malware we’re seeing coming out of China nowadays, many of which are targeting online games...Taterf, Frethog and their ilk are designed to steal your online game login details...
