• Gain persistent access for future attacks

Immediate Actions for Your Business

1. Update immediately: Apply the latest firmware updates from Fortinet that address this vulnerability.

2. Review administrator accounts: Check for any unfamiliar admin accounts that may have been created by attackers.

3. Audit firewall rules: Look for unauthorized policy changes or new rules that could indicate compromise.
