NSA is both red team and blue team. This is a blue team tool used by reverse engineers to analyze malware, so it was NSA's little gift to researchers, an agency known for hoarding secrets for our 'security'.

It's also a red team tool for binary exploitation.
EDIT: The cynic in me posits it was used far more for exploit development than for analyzing malware, unless that had offensive applications too. But I don't know anything, I never worked there.
