Malware That Changed The World – Sobig.F

SoBig.F

Back in 2003 many people were recovering from the notorious Blaster worm.

They didn’t get much respite though as a new threat came hot on its heels.

The Sobig.F computer virus infected millions of computers and  slowed or completely crashed Internet gateways and email servers, resulting in the mass slowing down of the worldwide Internet.

It harvested email addresses from various documents found on those computers that it had infected and then sent itself to those same addresses.

It was able to send millions of copies of itself within just a few hours of being unleashed.

Then, in September of 2003, it shut itself down, having been programmed to do so.

Since then there have been no further reports about the Sobig virus.

Though Microsoft announced a $250,000 bounty, much like they did with Conficker, the author of Sobig has never been apprehended.
