Apply mitigations per vendor instructions, follow applicable BOD 22-01 guidance for cloud services, or discontinue use of the product if mitigations are unavailable.
CISA has confirmed exploitation of this vulnerability. Federal agencies must patch within the KEV deadline. SMBs should treat this as P0: patch or mitigate within 24–48 hours.
VPN gateways are the primary attack surface for ransomware initial access. Apply the vendor patch immediately. If patching is delayed, consider temporarily disabling the VPN and using an alternative access method, or restricting access to specific IP ranges.
An attacker needs local access to exploit this. Focus on endpoint detection, privilege management, and preventing initial compromise (phishing, malicious USB).
SMB Attack Probability Score weights: EPSS exploit likelihood (35%), CISA KEV active exploitation (25%), SMB stack prevalence (20%), exploit maturity (10%), CVSS network vector complexity (10%). Impact scenarios are derived from software category and historical SMB incident patterns. Scores recompute daily.
