Tetris game contains dangerous worm

A new worm has appeared, by the name of Cellery-A (W32/Cellery-A). It makes changes to Windows settings to ensure that it automatically runs when the operating system starts up, and searches for other network drives and attached computers to also try and infect. Nothing new or interesting there, but there is more.

The worm hides itself inside a Tetris game. Just imagine the armies of clueless users out there, right now, happily pushing blocks around to try and score lines, unaware of the fact that they are infecting their machines and the machines of others.

"If your company has a culture of allowing games to be played in the office, your staff may believe this is simply a new game that has been installed - rather than something that should cause concern." - Sophos.
