Dutch NCSC: Critical Check Point VPN flaws exploitation is imminent

Dutch NCSC warns exploitation is imminent for critical Check Point VPN RCE flaws CVE-2026-85102 and CVE-2026-85103, urging immediate patching of Security Gateways.

The Dutch NCSC assesses the likelihood and impact of exploitation as high for two critical Check Point VPN flaws, though no public PoC exploit has been reported. CVE-2026-85102 is improper validation of certificate data during VPN negotiation, and CVE-2026-85103 is a heap overflow in the VPN certificate ASN.1 decoder; both enable remote code execution on Security Gateways, the latter also on Security Management Servers. Affected releases span R81.20, R82, R82.10, R81.10.x, R82.00.x and EoS versions R80 through R81.10, while R82.20 is unaffected. Check Point shipped fixes on September 9 via LivePatch Take 24 and Jumbo Hotfix Accumulator takes, and NCSC advises restricting Site-to-Site VPN rules to trusted IPs.

Wyden seeks upgraded NSA security guidance on commercial VPN use

Senator Ron Wyden asked the NSA to update public guidance on commercial VPN security risks and answer questions about foreign surveillance threats against single-hop VPNs.

Sen. Ron Wyden sent a letter to NSA Director Gen. Joshua Rudd urging the agency to revise public guidance on commercial VPNs, following earlier letters to federal agencies in March and July. He argues single-hop VPNs offer little protection against sophisticated adversaries able to compel or compromise the single provider, citing a Congressional Research Service paper favoring multi-hop and mixnet architectures. The letter references a September NSA advisory on a China-sponsored campaign against telecom, government and military networks and asks unclassified questions about multi-hop systems such as Apple Private Relay, Tor and Nym versus mixnets.

Surfshark VPN says hackers breached internal testing, proxy servers

Surfshark disclosed that hackers accessed misconfigured internal test and proxy servers, exposing build credentials but not customer data, VPN traffic, or production infrastructure.

Surfshark said a human error left an internal engineering test server reachable from the internet, exposing service configurations, build-related credentials, and portions of system binaries and code history. A separate proxy server used for content-accessibility optimization was also accessed, but it stored no user identity data, IP addresses, encryption keys, or browsing traffic. Suspicious activity was detected on August 31, contained on September 2, and remediation completed on September 5, with no evidence of credential misuse or spread to other systems. The company rotated impacted credentials, revoked exposed tokens, added monitoring and hardening, and commissioned an independent infrastructure audit; no customer action is required.

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.
