Mariposa

The name of a malicious botnet. Dubbed Mariposa, this widespread malware campaign managed to infiltrate more than 13 million PCs and more than half of the world's 1,000-largest companies.

Three men, who called themselves the "Nightmare Days Team" and dubbed their botnet projects "Mariposa," were arrested by Spanish authorities in February 2010 after a yearlong investigation by law enforcement agencies and security software vendors Panda Security.

The Mariposa �� the Spanish word for butterfly �� botnet was shut down on Dec. 23, 2009 after operating largely unhindered for almost a year. Mariposa accessed more than 13 million PCs in all, making it one of the largest and most destructive botnets in history.
