Right, they bug GnuPG for quite some time with their research ;-).
Their latest attack got public in February
(<http://www.cs.tau.ac.IL/~tromer/ecdh/>) due to an unexpected
publishing of the conference paper before the event.

The CACM paper mentions Enigmail and GpgOL. The former actually has the
ability to decrypt all incoming mails in advance after the passphrase
has been given once.
Die Gedanken sind frei. Ausnahmen regelt ein Bundesgesetz.
