statement to the contrary. In fact the whole attack is nearly 20 years
old and even back then it was hard to construct a case where the
non-authenticated encryption could be abused. When the PGP folks and me
discussed the attack around the year 2000, we knew that and suggested
signed mails as a solid counter-measurement. The MDC was then
introduced mainly to counter the more or less theoretical attack and to
be on the safe side in case better attacks would be developed.
The media and political coverage (we had working groups and internal
meetings) of the efail paper however required some extra measurements to

months without mentioning that all the major MUAs fixed the bug within a
few days or weeks or even had fixed it at the time the paper was
