The FBI recently announced the arrests of 10 people who had targeted Facebook users with the Yahos malware.
"The FBI said the arrests occurred in Bosnia and Herzegovina, Croatia, Macedonia, New Zealand, Peru, the United Kingdom, and the United States," writes CNET News' Steven Musil.
"The operation is said to have identified international cybercrime rings that used variants of a malware called Yahos," writes Computerworld's John Ribeiro. "The malware infected more than 11 million computers and caused more than $850 million in losses through a Butterfly botnet, which steals computer users' credit card, bank account, and other personal identifiable information, the FBI said in a statement late Tuesday."
"This is the second major outbreak of botnets based on the Butterfly (aka Mariposa) bot tool," writes Ars Technica's Sean Gallagher. "The first incarnation, discovered in December 2008 and shut down a year later, infected over 12 million PCs worldwide and was spread primarily through file-sharing and instant messaging attacks. It also harvested financial information from over 800,000 victims."
"The FBI did not elaborate on how it arrived at its $850 million theft figure, but that haul easily dwarfs the Eurograbber, which was revealed last week to have stolen about $47 million from European banking customers in the past year," writes CNET News' Steven Musil. "The Yahos spoils also surpass the take by the Zeus botnet crime ring, which infected an estimated 13 million computers with malware to steal more than $100 million."
