The NSA, National Security Agency may have had the email addresses of employees leaked on Jihadi web forums according to Evan Kohlmann. How authentic or sensitive this list is I can’t say. The NSA is the US equivalent to our CSEC, Communications Security Establishment Canada.
I do find this alarming in light of the recent release of a hacked phone call between the FBI and Scotland Yard.
This is the link to the information on the Ansar Al-Mujahideen Jihadi forum. I found it in 5 minutes of searching. Anyone else who wanted it already had it.
