Amnesty International developed the Detekt cyber security tool as a means of resisting surveillance from the US National Security Agency and other government organizations.
The tool, which works on Windows, scans users' computers for signs of FinFisher or Hacking Team RCS, both known commercial surveillance spyware systems. These programs allow third-parties the ability to comb through e-mails, eavesdrop on Skype conversations or even monitor the user by turning on the computer's camera and microphone.
Detekt is perfect for those who work in particularly sensitive industries, such as human rights or online journalism. If you believe you are at risk for government spying, you can protect the contents of your computer by running Detekt for traces of known spyware.
