The most annoying aspect to this letter is that it involves two companies I've never heard of.

Actually, now I don't know if that link has anything to do with the letter. It just has the same modus operandi.
Side note: if you're going to post a message about security incident, a date would be nice.
A bunch of technomancers in the fediverse. Keep it fairly clean please. This arcology is for all who wash up upon it's digital shore.
