A German public broadcaster's report claims that the NSA, through its XKeyscore program, is automatically capturing people's information after they search for the privacy programs. XKeyscore collects data from internet users and includes email content, websites visited, searches and metadata.
The report details NSA slideshows and how the agency aims to reveal Tor users' identities. Additionally, the researchers published XKeyscore's rules that the agency uses.
XKeyScore was initially disclosed last year through whistleblower Edward Snowden. Last month, further Snowden documents showed that the NSA is collecting images and using facial recognition to identify intelligence targets.
