ProLock was a financially motivated ransomware operation active in the broader cybercrime ecosystem and notably associated with QakBot-enabled intrusions into corporate networks. It is documented as one of several ransomware groups that partnered with or followed QakBot infections for initial access, indicating an intrusion model in which access brokers or malware distributors enabled downstream ransomware deployment against enterprise victims. ProLock is also linked in reporting to operational and technical overlap with Egregor, with some assessments noting that Egregor operators’ tradecraft was highly similar and that QakBot distributors shifted from delivering ProLock to delivering Egregor. Observed ProLock behavior includes inhibiting recovery by deleting Volume Shadow Copies through native Windows tooling, a common ransomware tactic intended to reduce restoration options before or during encryption. Available high-confidence information in this dataset supports ProLock’s role as a ransomware actor using brokered initial access and recovery inhibition, but does not provide sufficiently corroborated detail here on specific victim geography, sector concentration, organizational structure, or country of origin.
