The suspected ring leader of the massive Mariposa Botnet and a pair of other hackers have been arrested in their native Slovenia and will face charges that allege they cracked into the computer systems of several Fortune 1000 companies and international banks.
The three suspected hackers are allegedly tied to the widespread Mariposa Botnet, which infected millions of computers and allowed hackers to glean information from the infected machines and launch denial-of-service attacks.
"In the last two years, the software used to create the Mariposa Botnet was sold to hundreds of other criminals, making it one of the most notorious in the world," said FBI Director Robert S. Mueller III in a statement.
The Mariposa Botnet was disabled in February. At the time it was taken down, three suspected operators of the botnet were arrested by the Spanish Guardia Civil and are currently being prosecuted in Spain.
