Reading the mistakes made in the hack itself makes me wonder if black markets and money laundering are a skill they posses.
If you were lazy you could just hit up an existing vendor and ask them to sell your data in batches.
I’m not saying this would be a good idea, but it certainly wouldn’t be very difficult.
This will just intensely increase the scrutiny of where the data came from and they'd likely be caught anyway, unless they did a very clean job security-wise. Which very few people seem to be able to do when the feds really want you.
Moving to Russia or another country without extradition treaties would probably be a good first step of that plan.
