WikiLeaks published thousands of secret documents yesterday (March 7th) that describe CIA hacking tools used to break into targets' devices, including computers, mobile phones and smart TVs, from the biggest companies, among them Apple, Google and Microsoft. Included are descriptions of ways to bypass or defeat encryption, antivirus tools and other security features. Also described are using smart TVs to listen in on what's going on around them, and even hacking vehicle systems. The actual hacking tools themselves aren't in the documents, but WikiLeaks suggested it has them. Also not in the publication is any allegation of misuse of these tools by the CIA against U.S. citizens. It's unknown how WikiLeaks got the documents, whose disclosure some in the intelligence community have described as possibly being more damaging than the Edward Snowden leaks. WikiLeaks said it came from the CIA's Center for Cyber Intelligence, but didn't say if they were obtained through hacking or from an employee who stole and leaked them.
