Massive Brute-Force Campaign Hits 2.8 Million IPs Targeting VPNs & Firewalls

A staggering brute-force campaign has been detected involving over 2.8 million IP addresses, systematically attacking enterprise-grade VPNs and firewall appliances from vendors like Palo Alto Networks, Ivanti, Fortinet, and SonicWall. Security researchers discovered attackers using botnets and proxy networks to rotate IPs and evade detection systems.
The attackers aim to guess credentials through persistent login attempts and exploit misconfigured access portals. This campaign has raised critical alerts for zero-trust VPN deployments and better password policies.
