Vendor
15 vulnerabilities in Palo Alto Networks products are listed in CISA’s catalog of actively exploited vulnerabilities, 6 of them used by ransomware. Latest addition on May 29, 2026: CVE-2026-0257 (PAN-OS).
The GlobalProtect vulnerability patched in May is still an entry point for ransomware. On October 11, ReliaQuest named the Qilin and Settra groups. Updating is not enough: organizations must also hunt for suspicious VPN access.
A 28-year-old Russian suspected of being a leader of the Qilin ransomware group was arrested in Japan and transferred to Germany, authorities in North Rhine-Westphalia announced on October 7.
