@itlandytech: Ransomware groups are actively exploiting CVE-2026-0257, a critical authentication bypass vulnerability affecting Palo Alto Networks PAN-OS GlobalProtect and Prisma Access.  Key Takeaways for Security Teams: Threat Actors: Intelligence from ReliaQuest indicates that multiple ransomware groups—including Qilin and Settra—are actively leveraging this flaw.  The Vector: Attackers use the bypass to create unauthorized VPN sessions, bypassing traditional perimeter defenses via trusted remote access services.  The Stealth Factor: Because malicious traffic originates through legitimate VPN connections, it easily blends in with normal remote workforce activity.  Impact: Once inside, threat actors can conduct stealthy reconnaissance, steal credentials, move laterally, and exfiltrate sensitive data before deploying ransomware.  Recommended Actions: 1. Audit Remote Sessions: Inspect active GlobalProtect/Prisma Access sessions for anomalous user behavior or unexpected geographic logins. 2. Apply Security Patches: Immediately update PAN-OS and Prisma Access deployments to the latest patched versions provided by Palo Alto Networks. 3. Enhance Telemetry: Monitor internal network movement beyond the VPN perimeter to detect lateral movement early. Hashtags: #CyberSecurity #InfoSec #Ransomware #PaloAltoNetworks #GlobalProtect
