A global crackdown on buyers, sellers, and users of a software tool called Blackshades, which allows for remote control of a victims computer, has resulted in the arrests of 97 hackers in 16 countries. Blackshades infected nearly half a million computers, according to the FBI, resulting in stolen financial information, identity theft, and extortion of the victims. Blackshades has legitimate uses similar to remote control software like GoToMyPC, which allow people to control their work computers from home and vice versa. The tool was advertised for spying on spouses, children, and anyone who might be tampering with your computer, according to Adam Kujawa, who first wrote about the Blackshades threat in 2012.
