      You wanted an example of working x86 knowledge and making bad crypto mistake. I gave you one. Petya v1 truncated 32 bit ints to 16 bit ints.

      yes, it is very unlikely that they were so incredibly stupid to not understand this much basic things. those that Janus did were non trivial

      in addition, there was enough material online about Petya and how it's Salsa key is preserved

      yet, we cannot exclude the option that they did it for money. they may not have cared for a sustainable business model

      maybe it was just their one time stand - to release once, collect as much money as possible and get away with it

      If money was their main goal then they made several massive mistakes which limited the payments and now have law enforcement after them.

      If you're in ransomware to make money you want to draw as little as attention as possible, don't get too greedy or target too big.

      personally, at the moment I am also more towards the theory of disruption, but it is not the only option. still we don't have enough proofs

      disruption is a solid theory, with all the other hacking coming from Russia directed at the Ukraine, but yea, the lack of enough proof

      Using my theory of digitally enforced "sanctions" regime, wouldn't the data collection be a big part of that? Is it going to any C&C?

          No, no C&C, but that's not unusual for ransomware, either. Normally the key is communicated to the server via the user ID.

          What happens to the data it collects (internal and external to the network, right?)

          It doesn't really collect data. Yes, it collects user accounts, but only so that it can spread to other machines, not to report.

          OK thanks. Could it collect data?

          Replying to @emptywheel @VessOnSecurity and

          Yes. The problem with having viruses collect data is that they collect too much stuff that you don't care about.

          The other problem is that virus writers really aren't smart. They can repeat a known model (e.g ransomware) but not come up with new ideas
