Hackers Exploit FortiGate SSL-VPN Flaw to Breach Thai ISP and Deploy MeshCentral Backdoor

Threat actors exploited FortiOS SSL-VPN flaw CVE-2024-21762 to breach Thai ISP Triple T Broadband, gaining root-level persistence via MeshCentral agents.

Attackers exploited CVE-2024-21762, an out-of-bounds write enabling unauthenticated RCE in FortiOS SSL-VPN, against Triple T Broadband's FortiGate 60F at mail.3bb.co.th, launching a Node.js reverse shell via a ROP payload. Hunt.io uncovered the operation through an exposed staging directory at 92.63.180[.]133:8888 containing 298 files of exploits, credential-harvesting scripts, session cookies, and a device inventory. Post-compromise, the actors deployed MeshCentral agents (device group TH-3BB, C2 www.ayuthayatech.com) running as root, plus a hidden SUID backdoor at /usr/local/bin/.rc, and also targeted an internal Pentaho/Tomcat server with Ghostcat (CVE-2020-1938). A cleanup script removed logs, shell histories, and web shells while deliberately preserving the MeshCentral agent and SUID backdoor.

Cisco Secure Firewall Adaptive Security Appliance and Secure Firewall Threat Defense Software SSL VPN Denial of Service Vulnerability

Cisco expanded an SSL VPN denial-of-service advisory to cover all ASA and FTD software platforms; unauthenticated attackers can exhaust device memory.

A vulnerability in the VPN and management web servers of Cisco ASA Software and Cisco Secure FTD Software allows an unauthenticated remote attacker to exhaust system memory or buffer blocks, causing a denial of service. Originally scoped to the ASAv and FTDv virtual appliances, Cisco updated the advisory on September 16, 2026 to cover all ASA and FTD platforms.

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.

Iranian banks' SSL certificates are being revoked due to OFAC sanctions

OFAC sanctions are reportedly causing Iranian banks' SSL certificates to be revoked, threatening secure HTTPS access to their services.

A Hacker News discussion highlights a report that Iranian banks' SSL/TLS certificates are being revoked as a consequence of OFAC sanctions. Certificate revocation would degrade or break trusted HTTPS connections to affected banking domains for users in Iran. The item is a headline-only discussion post with limited detail on which certificate authorities or banks are affected.

Chinese-Speaking Hackers Use Noodle RAT Backdoor to Spy on Windows and Linux Systems

Chinese-speaking actors use cross-platform Noodle RAT backdoor to maintain covert access to Windows and Linux systems across Asia-Pacific.

Noodle RAT (also ANGYREBEL/Nood RAT) has been active since at least mid-2016 and was long misidentified as Gh0st RAT or Rekoobe variants until Trend Micro and Cyberint classified it as a distinct multi-platform family. The Windows build (Win.NOODLERAT) is an in-memory modular shellcode backdoor delivered via MULTIDROP and MICROLOAD loaders, while the Linux build supports reverse shells, SOCKS tunneling, and cron persistence after web shell or public-facing service exploitation. It has appeared in intrusions in Thailand, India, Japan, Malaysia, and Taiwan and is linked to Iron Tiger, Calypso APT, Rocke, and Cloud Snooper campaigns spanning espionage and cybercrime. Recently discovered Linux builders 1.0.1 and 1.0.2 indicate the toolkit remains actively maintained.

Thai Broadband Provider Hacked via Fortinet Vulnerability

Hackers exploited Fortinet CVE-2024-21762 RCE to breach Thai broadband provider 3BB, deploying MeshCentral backdoors and credential-harvesting tools across its network.

Hunt.io uncovered an intrusion staging directory in Thailand containing 298 files of custom tooling built for Triple T Broadband (3BB) and its former owner Jasmine. Initial access came via fingerprinting a FortiGate SSL-VPN appliance and exploiting CVE-2024-21762 for remote code execution, after probing CVE-2018-13379, CVE-2022-42475, and CVE-2023-27997. The actor also probed F5 BIG-IP for CVE-2021-22986, CVE-2022-1388, and CVE-2023-46747, escalated privileges with PwnKit and Dirty COW, used MeshCentral as a C2 backdoor, harvested SSH/database/SNMP/Radius credentials, deployed PHP web shells, and ran cleanup scripts to hide the intrusion.
