Stop the Next Kaseya Attack

While many Americans were on holiday, attackers exploited a zero-day in the on-premises Kaseya VSA management server to distribute REvil ransomware in a supply-chain campaign that affected 40–60 MSPs and more than 1,000 of their customers; the report outlines REvil’s common entry methods (phishing, RDP compromise, WebLogic exploits), the prevalence of double extortion (data theft plus encryption), and prescribes Zero Trust controls—full traffic inspection, microsegmentation, least-privilege access, DLP, CASB, and active deception—to prevent compromise, lateral movement, and data exfiltration.
