Hackers Allegedly Selling Fortinet FortiGate 1-Day Vulnerability on Underground Forums

An unverified underground listing offers a claimed FortiGate SSL VPN RCE exploit for FortiOS 7.2.x/7.4.x amid ongoing exploitation of known Fortinet flaws.

Dark Web Intelligence shared an advertisement for a private '1-day' remote code execution exploit targeting FortiGate SSL VPN appliances on FortiOS 7.2.x and 7.4.x, with a claimed proof-of-concept video but no CVE, firmware builds, or technical details. The listing coincides with confirmed in-the-wild exploitation of CVE-2025-25249, an unauthenticated heap-based buffer overflow patched in January 2026 but exploited since July 2026, and CVE-2024-21762, a critical out-of-bounds write in the FortiOS and FortiProxy SSL VPN component. Fortinet has advised disabling SSL VPN where immediate upgrades are not possible.

New SETTRA Ransomware Uses MeshAgent RMM and BYOVD to Encrypt Windows Systemsnew

Huntress reports new Settra ransomware hit retail and manufacturing firms, using MeshAgent RMM, BYOVD, and Windows utilities to encrypt systems and block recovery.

Huntress investigated two Settra intrusions: a consumer services and retail organization in July 2026 and a manufacturing firm in September 2026, showing nearly identical post-compromise behavior. Operators installed the MeshAgent RMM, ran ransomware executables named after the victim domain (_win64.exe), encrypted files with .locked or .locked_wip extensions, and dropped RESTORE_FILES.txt ransom notes. In both cases attackers cleared Windows Event Logs, disabled the Windows Recovery Environment, and used DiskPart to remove the recovery partition; the July case also ran Cipher to overwrite free space and flushed DNS cache. The September incident added BYOVD using gdrv.sys, and initial access was suspected via VPNs or previously stolen credentials, though unconfirmed.
