(Newser) – A hacker responsible for hijacking more than 10 million computers around the world has been arrested in Slovenia after a major international investigation, the FBI says. The 23-year-old hacker, known as "Iserdo," is accused of masterminding a scam in which the Mariposa "botnet" network infected computers belonging to dozens of banks and more than half the Fortune 1,000 companies, the AP reports.

Investigators say Iserdo sold the malware to hackers, who sometimes paid extra to have it customized. "To use an analogy here," an official in the FBI's cyber division says, "as opposed to arresting the guy who broke into your home, we've arrested the guy that gave him the crowbar, the map, and the best houses in the neighborhood. And that is a huge break in the investigation of cyber crimes." (Read more Iserdo stories.)
