In 2015 Der Spiegel released this slide-deck, provided to them by Edward Snowden. The slide-deck was a TOP SECRET internal presentation that the NSA's VPN Exploitation Team (internally designated as S31176) was doing to new SIGINT analysts of the Agency in order to introduce them to what their team, part of NSA's OTP (Office of Target Pursuit), could provide in terms of decrypting VPN traffic.
