New version of Sasser undermines lone coder theory

The appearance of a new version of the infamous Sasser worm shortly after the arrest of its admitted author has fuelled speculation that its creator worked with other virus writers.

Sasser-E was first spotted three hours and 45 minutes after the arrest of Sven Jaschan, 18, from Rotenburg in northern Germany at 2pm on Friday afternoon (local time). Either earlier sightings of the fast-spreading worm were missed or Sasser-E was released by someone other than Jaschan, who was released from police custody after the new version of the worm arrived onto the scene.

Spanish AV firm Panda Software said the appearance of the variant showed there was an "organised group of delinquents" involved in distributing copies of the prolific worm.

Finnish AV firm F-Secure is not so sure: "We believe Mr. "SJ" (who has confessed to writing all the Sasser and NetSky variants) had distributed this version shortly before his arrest. He has been released on bail, but this was only after first reports of this new variant were in. The E variant does not appear to be a hack done by someone else." Circumstantial evidence led F-Secure and many in the AV community to suspect that the NetSky series was the work of multiple authors, a conclusion undermined by Jaschan's confession.

Ik denk dat het wel een lone coders verhaal is, alleen zijn die lone coders wel met elkaar in contact. Overigens is de sourcecode van virii als Sasser wel te downloaden en eignelijk kost het niet veel inzicht en moeite om het aan te passen. Ik ben niet zo'n programmeur maar ik heb wel rootkits gezien die niet gecodeerd waren en ik begreep prima wat ze deden en wat ik eraan moest/kon doen. Dus als Fluffy Bunny in de bak zit dan is het wel elegant om een nieuwere variant los te laten indirect pleit je de verdachte daarmee vrij.

Uhm, Fluffy Bunny was maar een, welliswaar niet geheel, fictief voorbeeld ;)
