No, not REALLY... but these guys stuck a bit of (badly phrased) parody lyrics (“U Can't Trust This“) in their advisory on the Microsoft ASN.1 security flaw.  And Microsoft thanked them anyway.

I generally argue against Microsoft's detractors when flaws are exposed like this, but I have to admit that in a case where Kerberos and NTLM authentication are exposing the flaw it's hard to be on the defense side of the argument.
