More and more, governments are using powerful spying software to target human rights activists and journalists, often the forgotten victims of cyberwar. Now, these victims have a new tool to protect themselves. It scans a person's computer for traces of surveillance software, or spyware.

A coalition of human rights organizations launched it, with the goal of equipping activists and journalists with a free tool to discover if they've been hacked. The open-source tool was developed by security researcher who has been investigating government abuse of spyware for years. The tool designed to discover malware developed both by commercial firms, as well as popular spyware used by cybercriminals.
