Notice I said “breached” and not “hacked”!
I did this because hacked means something beyond social engineered or more specifically phished.
FireEye which is a huge (if not the biggest) Cyber Security firm.
They annouced a few days ago that they were breached and their data was stolen.
This included internal techniques, tools and procedures (TTPs)
They released IoCs y’all should add to your ID/PS’s and etc which are linked HERE
What is interesting to note that their codenames are similar to the NSA toolset and even some of the CIAs toolset that were leaked.
Obviously no-one would be surprised if they intermingled.
Anyway, here are some good articles on the fireeye breach.
