German authorities have searched five homes near the village where the teenager who created the crippling Sasser computer worm was caught last week, Reuters reports. They had previously believed the youth, a student of computer science at a vocational college, had worked largely alone, merely exchanging ideas with fellow students. "The assessments that have followed have now supported the suspicion that others were involved in distributing the virus," police in the state of Lower Saxony said in a statement Wednesday. Two of those questioned had admitted to receiving the source code to the related Netsky worm from the author of Sasser, but only one had admitted to distributing Netsky. Police gave no further details, saying the investigation was still under way.
