According to several reports across the 'net, NASA revealed in a log report that a worm was discovered on some laptops aboard the International Space Station.

The worm, known by some as Gammima which we call Worm:Win32/Taterf.gen!C, is at least a year old.

NASA is known to perform experiments involving the order "Oligochaeta" whereas the Gammima worm does not thrive in the dirt. There is speculation on how exactly the computer worm arrived onto the lab laptops but as of yet, "mum's the word". According to NASA spokesman Kelly Humphries - "This is not the first time we have had a worm or a virus. It's not a frequent occurrence, but this isn't the first time."

The password stealing malware did not affect critical systems, according to the report.
