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.
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?
-
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
