NSA FoxAcid?

And we know since a while (1999)! Interview with Larry Wall:
Marjorie: Who is using Perl and how are they using it?

Larry: A couple of years ago, I ran into someone at a trade show who was representing the NSA (National Security Agency). He mentioned to someone else in passing that he'd written a filter program in Perl, so without telling him who I was, I asked him if I could tell people that the NSA uses Perl. His response was, “Doesn't everyone?” So now I don't tell people the NSA uses Perl. I merely tell people the NSA thinks everyone uses Perl. They should know, after all.
