This week, NASA confirmed that a virus has infected at least one computer on the International Space Station.

The malware was detected on July 25 by antivirus software, a NASA spokesperson informs. The bug is called W32.TGammima.AG and is, as anti-virus software manufacturer Symantec describes it, a Windows-based worm which spreads by copying itself onto removable media and steals passwords for online games.

On Symatec’s website, it is rated as a very low-risk virus.

NASA refused to state how the computers got infected, although an entry on their site says that digital camera storage cards could be to blame.

Space station Commander Sergey Volkov was the first person to report the virus’ discovery, on August 11, in the daily log, reporting that he had found it while running a virus check for digital photo flash cards with the Norton AntiVirus application.

NASA spokesperson admitted that this isn’t the first time such a “nuisance”-as he puts it-has occurred, adding that the flash memory cards that are scheduled to be launched to the station next month have already been screened for viruses.

Currently, the team on the space station consists of Russian cosmonaut commander Sergei Volkov, cosmonaut flight engineer Oleg Kononenko and NASA flight engineer Greg Chamitoff, the former two being due to return in October, while the latter will be returning after his replacement for the shuttle’s November mission arrives.

The Gammina bug, which executes whenever Windows starts, steals information from online games such as ROHAN, R2 (Reign of Revolution), Talesweaver and Seal Online.

For NASA’s sake, the space station’s crew better not be hooked on any of these.
