Large Password-Spraying Campaign Targets Cisco, PAN VPNs
🔐 An automated password-spraying campaign is targeting multiple VPN platforms, with credential-based attacks observed against Palo Alto Networks GlobalProtect portals and Cisco SSL VPN gateways. GreyNoise recorded login attempts peaking at 1.7 million over 16 hours from more than 10,000 unique IPs, largely originating from the 3xK GmbH hosting space. The actor reused common username/password combinations and used an unusual Firefox user agent, indicating scripted credential probing rather than exploitation. Administrators are advised to enforce strong passwords, enable MFA, audit appliances, and block known malicious IPs.
