More promising (from my point of view) is killing X.509 and replacing it with OpenPGP, which is what www.mokeysphere.info is doing. "Sarad AV" <jtrjtrjtr2001@yahoo.com> wrote:

If you have any further information on it or any other countermeasures implemented, please do keep us in loop. this attack is upsetting.

For IP if you'd like.
Over a decade ago, I observed that commercial
protect you from anyone from whom they are unwilling to take money. That turns out to be wrong; they don't even do
