Your edge gateway is the first thing attackers will test today. 🛡️
CVE-2026-4401 · Severity 8.6 · Active exploitation of GlobalProtect portals in @[Palo Alto Networks](urn:li:organization:10620) PAN-OS.
Threat researchers at @[Mandiant](urn:li:organization:264848) have identified a new campaign targeting perimeter security devices. Attackers are using a sophisticated memory corruption exploit to gain initial network access.
This allows them to tunnel directly into your internal network, bypassing standard VPN identity checks. We are seeing these attempts move from targeted to broad scanning in the last 24 hours.
The uncomfortable truth: Your perimeter security is a single point of failure if you haven’t implemented Zero Trust internal controls.
→ Disable the GlobalProtect portal on non-essential interfaces.
→ Update PAN-OS to the latest maintenance release immediately.
→ Enable advanced threat prevention signatures for known exploit patterns.
