BERLIN (AP)An 18-year-old German who confessed to creating
the "Sasser" computer worm launched a new version meant to limit
the damage just before his arrest last week, investigators said
Authorities who have questioned Sven Jaschan got the impression
his motive was to gain fame as a programmer, prosecutor Detlev
He labeled as speculation news reports that he may have created
the disruptive program to drum up business for his mothers
computer store, PC-Help, in the small town of Waffensen.
"One can never rule out anything, but there are no facts to
suggest it," he told The Associated Press by telephone.
Jaschan was arrested Friday
at his mothers house, where police
said agents found him sitting at his computer. Investigators say
the machine contained the worms source code.
Earlier Friday, investigators said, Jaschan unleashed the new
"Sasser e"a failed attempt to limit the damage caused by the
four previous versions.
Frank Federau, a spokesman for the state criminal office in
Hanover, said the worm was "a slightly modified form" of the
program that raced around the world over the past week, exploiting
a flaw in Microsofts Windows operating system.
"He did it with good intentions, but it had exactly the same
damaging effects," said Sascha Hanke, a Microsoft data protection
official in Germany.
Like the other versions, the new variantwhich notified users
of a Microsoft patch against Sassercaused computers to crash and
"The cause was erroneous programming of the virus," Hanke
said. Police have said Jaschan was responsible for all versions of
Sasser as well as the "Netsky" virus.

He is being investigated on suspicion of computer sabotage,
which carries a maximum sentence of five years in prison. He was
released pending charges after questioning last Friday, where he
admitted creating Sasser, police said.
A trial could begin at the end of June, Dyballa said.
Investigators are examining computer.
