Two researchers are being singled out in what are called PGP poisoning or flood attacks that render the authentication tool unusable for victims.
A long-feared attack vector used against Pretty Good Privacy, the framework used to authenticate and keep email messages private, is being exploited for the first time. The attack, which takes aim at keyserver verification directories, makes it impossible for Pretty Good Privacy (PGP) to work properly for those targeted in attacks.
Unknown adversaries have singled out two recognized experts in the field of OpenPGP email encryption, Robert Hansen and Daniel Gillmor, in a series of targeted attacks. OpenPGP refers to the standard that uses the cryptographic privacy and authentication program PGP.
