2. Block or restrict access to untrusted websites and email attachments containing links until patching is complete
3. Enable browser sandboxing and security features in all Chromium browsers
PATCHING GUIDANCE:
1. Update Google Chrome to version 105.0.5195.102 or later
2. Update Microsoft Edge to version 105.0.1343.42 or later
3. Update Opera to version 91.0 or later
4. Deploy patches through MDM/EMM solutions for enterprise devices
5. Verify patch installation across all endpoints within 48 hours
COMPENSATING CONTROLS:
1. Implement web content filtering to block known malicious domains
2. Deploy email gateway security with URL rewriting and sandboxing
3. Enforce browser isolation technology for high-risk users
4. Implement network segmentation to limit lateral movement if compromise occurs
5. Monitor for suspicious process execution and memory corruption indicators
DETECTION RULES:
1. Monitor for abnormal process termination and browser crashes
2. Alert on suspicious heap memory access patterns
3. Track browser plugin/extension installations from untrusted sources
4. Monitor for unusual network connections initiated from browser processes
5. Log and alert on failed browser sandbox escapes or privilege escalation attempts
