Sasser.F, spotted in the wild yesterday, has not been changed much from the original five variants, firms said. Last Friday, German police arrested 18-year-old Sven Jaschan on suspicion of creating Sasser, which caused headaches and economic damage around the world, infecting, it is estimated, several hundred thousand Windows computers.
Another Sasser found
A new minor variant of the Sasser network worm has been found, despite the arrest last week of the suspected author, according to anti-virus software companies.
