Attackers Target Exposed Palo Alto Networks Management Interfaces

Threat actors are actively targeting recently patched security vulnerabilities in Palo Alto Networks devices with management interfaces exposed to the public internet. If an administrative portal is publicly accessible, attackers can exploit these flaws to compromise the device and access your network. Organizations using these appliances must immediately secure their devices to prevent unauthorized control.
