ShinyHunters has a vested financial stake in not leaking the customer data. If they did, nobody would ever pay a ransom to them again. I trust ShinyHunters to look out for themselves continuing to get paid.
This is a really silly take. Instructure also had a financial incentive not to get hacked. And yet…
Sure. Do you trust every member of ShinyHunters to remain a member of ShinyHunters in good standing, and to resist the temptation to exfiltrate the data in the process of exiting ShinyHunters?
