Critical Check Point VPN Flaws Let Unauthenticated Attackers Execute Remote Code

Check Point fixed critical unauthenticated RCE flaws CVE-2026-85102 and CVE-2026-85103 in its VPN gateways; no exploitation observed yet.

Check Point disclosed two critical vulnerabilities affecting Remote Access VPN and Site-to-Site VPN on its security gateways. CVE-2026-85102 is an authentication-bypass flaw that can lead to unauthenticated remote code execution, while CVE-2026-85103 is a heap overflow in ASN.1 decoding that can corrupt memory and also result in RCE. Fixes are available via Jumbo Hotfix, with Check Point Live Patch rollout starting September 9, 2026; the vendor found and fixed the issues through internal research and reports no evidence of exploitation in the wild.

Windows 11 Security Update KB5124008 Breaks Always-On VPN Connections

Microsoft's September 2026 Windows 11 update KB5124008 breaks certificate-based Always On VPN on some enterprise clients, forcing admins to pause rollout.

Microsoft's September 8, 2026 cumulative update KB5124008 for Windows 11 24H2 (build 26100.9445) and 25H2 (build 26200.9445) breaks certificate-based Always On VPN tunnels on some enterprise clients, with connectivity restored after uninstalling the update and rebooting. The issue was first detailed on Microsoft Q&A on September 9 by an administrator using Intune-deployed VPN profiles with RRAS and NPS on Windows Server 2019. The same mandatory Patch Tuesday package fixes two actively exploited zero-days, CVE-2026-81963 in the Windows Update Stack and CVE-2026-85880 in Windows Advanced Local Procedure Call, so many teams are pausing only VPN cohorts rather than blocking the full rollout.

Non-Zero-Day VPN Flaw Left Japan ‘s Government Shared Network Platform Exposed: 246,000 Records at Risk

Japan's Digital Agency says attackers exploited a patchable VPN flaw to access a government shared platform, exposing records of ~246,000 employees across 23 ministries.

Japan's Digital Agency disclosed that attackers exploited a medium-severity, already-patchable vulnerability in a VPN device to access the Government Solution Service (GSS), potentially leaking personal data of roughly 246,000 government employees, officials, and contractors across 23 ministries. The intrusion was detected on June 25 and confirmed as VPN exploitation on July 9, with public disclosure 78 days after detection. Exposed data includes about 236,000 names, 231,000 email addresses, 94,000 phone numbers, and 1,000 physical addresses; no My Number, bank account, or pension numbers were included. The compromised maintenance staff account was suspended and the compromised hardware isolated, but the VPN product and flaw were not disclosed.

Microsoft Exchange Vulnerability CVE-2026-62911: What Administrators Should Do and How Zscaler Can Help

High-severity authentication bypass CVE-2026-62911 in Exchange Server has public exploit code; about 22,000 servers remain unpatched and internet-exposed.

Microsoft's August 2026 Patch Tuesday fixed CVE-2026-62911 (CVSS 8.0), an authentication bypass affecting Exchange Server 2016, 2019 and Subscription Edition. Successful exploitation lets an attacker with basic privileges take over all mailboxes on the targeted server, including reading and sending email and downloading attachments. As of September 1, Shadowserver identified roughly 22,000 unpatched, internet-exposed Exchange servers, including about 6,200 in the US and 5,100 in Germany. NCSC-NL confirmed working exploit code is publicly available, while CISA has not yet reported exploitation in the wild.

Confused about which VPN is right, US senator asks the NSA for guidance

Senator Ron Wyden asked the NSA to update public guidance on VPN configurations, questioning single-hop designs and services like Tor.

Sen. Ron Wyden (D-Ore.) sent a letter Wednesday to NSA director Gen. Joshua Rudd requesting updated public guidance on VPN best practices for Americans facing advanced foreign threats, including government personnel, contractors, and journalists. The letter highlights limitations such as decrypted traffic at single-hop termination servers, metadata like timestamps enabling nation-state profiling, and asks the NSA to assess multi-hop architectures, random delays, cryptographic padding, and specific services including Apple Private Relay, Nym, and Tor.

OpenAI banned Russian ChatGPT accounts backing covert influence operation

OpenAI banned Russian-run ChatGPT accounts behind fake think tank IBI, which used AI-generated posts and a 'Sovereignty Index' to push pro-Russia narratives.

OpenAI banned a cluster of ChatGPT accounts, likely operated from Russia via VPNs, that generated English-language social media comments for X, Facebook, LinkedIn, Telegram and Substack promoting the International Burke Institute (IBI). The Israel-branded IBI website, registered in February 2025, claimed ties to figures like Francis Fukuyama, but 34 of 36 sampled articles were copied or misattributed. Its 'Sovereignty Index' consistently ranked Russia favorably while criticizing France, Germany, the EU and the US; OpenAI rated the campaign at the lower end of Brookings Breakout Scale Category Three.

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.

737 Chrome VPN Extensions Caught Routing Traffic Through Proxies. Check If You Have One

Researchers found 737 Chrome VPN extensions, many impersonating brands like NordVPN, routing roughly 75,000 users' browser traffic through attacker-controlled SOCKS5 proxies.

Socket and researcher Kush Pandya identified 737 Chrome VPN and proxy extensions, published across at least 40 developer accounts with 75,486 installs, that route entire browser sessions through one provider's SOCKS5 proxies on port 1082. Of these, 274 impersonate 66 established brands including Proton VPN, NordVPN, Surfshark, ExpressVPN, and Cloudflare 1.1.1.1. The proxy bypass list only excludes loopback addresses, exposing visited destinations, source IPs, TLS SNI values, and plain-HTTP request bodies to the operator. 221 extensions have been removed from the Chrome Web Store while 516 remain listed as active.
