The ransom payments tend to be so big anyway that selling the data and associated reputational damage is most likely not worth the hassle.
Basic game theory shows that the best course of action for any ransomware group with multiple victims is to act honestly. You can never be sure, but the incentives are there and they’re pretty obvious.
The big groups are making in the neighbourhood of $billions, earning extra millions by sabotaging their main source of revenue seems ridiculous.
Whoa. You're a crime organization. The data may as well "leak" the same way it leaked out of your victim's "reputable" system.
Yes, the data might still leak. It’s absurd to suggest that it’s not less likely to leak if you pay.
There’s a reason why businesses very frequently arrive at the conclusion that it’s better to pay, and it’s not because they’re stupid or malicious. They actually have money on the line too, unlike almost everyone who would criticise them for paying.
However they don’t really need to because there are plenty of documented cases, and the incident response company you hire will almost certainly have prior knowledge of the group you’re forced to deal with.
If they had a history of fucking over their “customers”, the IR team you hired would know and presumably advise against paying.
