CVE-2026-0300 is a critical buffer overflow vulnerability in the User-ID Authentication Portal service, also known as Captive Portal, within PAN-OS. It allows unauthenticated remote attackers to send specially crafted packets and achieve arbitrary code execution with root privileges on affected PA-Series and VM-Series firewalls. The flaw stems from improper handling of input data in the authentication portal component, enabling out-of-bounds writes that corrupt memory and grant full system control.

Ransomware has moved beyond simple malware attacks. It is now operating under a structured business model that disrupts operations, not just systems. Attackers are not depending on phishing or malicious files to deploy ransomware. They instead use compromised identities and existing tools present within environments to move undetected. By the time encryption starts, the attack has already progressed across systems.

In the IT world, there is something quietly sinister about a bank holiday. It’s not the holiday itself – who doesn’t love a bank holiday – a long weekend, a reason to grill something in unpredictable weather, the particular pleasure of feeling like you’ve slipped a Monday… The sinister part is structural.
