Did the NSA Get Hacked?

A group calling itself the “Shadow Broker” posted a trove of files online Monday, claiming it contains cyberweapons stolen from hackers called the Equation Group—allegedly the elite hacking arm of the National Security Agency.

The announcement appeared in broken English on a Tumblr account—now inactive but preserved in Google’s caches—along with two encrypted file archives available for download. “Shadow Broker” provided the password for one of the archives to prove the files’ authenticity, but demanded payment in Bitcoin for the password to the second archive.
