I suspect there will be more stories about this in the days to come, just headline information for now as this was just published minutes ago:
WASHINGTON — The FBI says international law enforcement authorities have arrested the computer hacker responsible for creating the malicious computer code that infected about 12 million computers and invaded major corporations worldwide.
The alleged mastermind is a 23-year-old Slovenian whose Internet nickname is Iserdo. The FBI says he was arrested in Slovenia after a lengthy investigation by police there, along with FBI and Spanish authorities.
His arrest comes about five months after Spanish police arrested three hackers in the cyber scam who operated the so-called Mariposa botnet, stealing credit cards and online banking credentials.
A botnet is a network of infected computers. The Mariposa botnet appeared in December 2008.
