Ps not condoning the theft but I just find it strange that people with the skills to steal this much get caught using bog standard cloud storage. You'd think they could afford something better ;) Something along the lines of "you don't take notes on a criminal f** conspiracy" :)
people in Tech will yak-shave choosing the "correct" cypher. Then get pwned by an implementation detail like a bug in enigmail.
1) Hacking, 2) opsec and 3) tradecraft are totally different skills. The most dangerous people (to themselves) are the ones who cover only one of 3. The more advanced among them _know_ they lack in the other areas, but think they can compensate going even deeper on whatever they already know.
That’s 30+ years of storage for free.
