Ransomware criminals are increasingly using mining pools to launder money, with the value sent from ransomware wallets to mining pools increasing steadily, according to a report by blockchain analysis firm Chainalysis. But cryptocurrency funds stolen in ransomware attacks have fallen sharply, and cryptocurrency revenue from such extortion will drop by 40.3% in 2022, mainly because more and more victims refuse to pay. Chainalysis says the most important solution is for mining pools and hashing services to institute stricter wallet screening measures beyond KYC.
