tsu doh nimh writes: The U.S. Justice Department announced today an international law enforcement operation to seize control over the Gameover ZeuS botnet, a sprawling network of hacked Microsoft Windows computers that currently infects an estimated 500,000 to 1 million compromised systems globally. Experts say PCs infected with Gameover are being harvested for sensitive financial and personal data, and that the botnet is responsible for more than $100 million in losses from online banking account takeovers. The government alleges that Gameover also was rented out to an elite cadre of hackers for use in online extortion attacks, spam and other illicit moneymaking schemes. In a complaint unsealed today, the DOJ further alleges that ZeuS and Gameover are the brainchild of a Russian man named Evgeniy Mikhailovich Bogachev, a.k.a. "Slavik."
