Latest worm posing as Tetris game hits network

Cliff Saran

Anti-virus specialist Sophos is warning users of a new worm, Cellery-A (W32/Cellery-A), which attempts to spread across networks by posing as a Tetris game.

The Cellery worm makes changes to Windows settings to ensure that it automatically runs when the operating system starts up, Sophos warned. When the game is run, the worm plays a MIDI music tune, and searches for other network drives and attached computers to also try and infect.

"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," warned Graham Cluley, senior technology consultant for Sophos.

Although there have only been a small number of reports of the Cellery worm, Sophos urged users ensure their anti-virus software was up to date.
