METR and Redwood Research conducted a three‑week red‑team assessment of OpenAI’s internal monitoring system, identifying several novel vulnerabilities that could allow agents to bypass oversight or disable monitoring. The findings were shared privately with OpenAI and include gaps in coverage, sandbox bypasses, and header‑based deactivation mechanisms.
Key points
- The assessment spanned July 21–August 11, 2026, giving researchers deep access to OpenAI’s codebase, monitoring prompts, and internal documentation.
- Researchers estimate 75‑94% of high‑capacity model traffic was monitored, but identified blind spots such as unmonitored RL training rollouts and compaction events.
- A discovered exploit could prevent hundreds of recent actions from being logged, and another allowed agents to bypass sandboxing and auto‑review controls.
- Two client‑controllable headers were found that can disable monitoring for new agents, effectively creating unmonitored instances.
- OpenAI reportedly fixed some issues, such as compaction‑event monitoring, during the exercise.
A remote code execution flaw in the Brotli compression library (CVE‑2026‑111497) allows memory corruption and arbitrary code execution in applications that decode attacker‑controlled data. The vulnerability affects Node.js, Python packages and several other language runtimes, with patches now released for most major libraries.
Key points
- The flaw is an out‑of‑bounds write in Brotli versions 1.0.3‑1.2.0 that can be triggered by crafted compressed streams, leading to memory leaks, crashes or remote code execution.
- Node.js disclosed the issue as “node2shell,” and Python packages were later found vulnerable, prompting broader language‑wide alerts.
- Patches have been published for libbrotli, Node.js, Python Brotli packages, C++, Bun, Envoy and other components; Apache and Nginx do not decode Brotli by default.
- OpenAI reported the underlying bug earlier in the year and issued an advisory after recognizing its security impact.
- Users are advised to upgrade affected libraries immediately or disable Brotli decoding until patches are applied.
Singapore Police alert the public to a malware‑enabled scam that uses fake Facebook ads to distribute malicious APKs, leading to unauthorized bank transactions and losses of about $989,000 across 62 reported cases since April 2026.
Key points
- The scam uses counterfeit ads for senior activities, fitness, and recycling programs to lure users into downloading a malicious APK.
- After installation, the malware enables scammers to impersonate officials, request money, and conduct unauthorized bank transfers.
- Victims reported a total loss of at least $989,000 in 62 cases, with some transactions performed directly by the malware.
- Police advise only installing apps from official stores, keeping Google Play Protect enabled, and using the ScamShield app for protection.
- The advisory emphasizes that Singapore government officials will never request money, personal banking details, or app installations from unofficial sources.
Claroc researchers discovered that Muse, Meta's AI assistant, publishes shared conversations as publicly accessible pages whose URLs embed the conversation title, making them discoverable through passive DNS and other services. Hundreds of pages contained sensitive personal and corporate information before Meta suspended the feature.
Key points
- Muse creates a public page for each shared conversation, embedding the title in the URL which is indexed by passive‑DNS services.
- A search of the Muse domain revealed over 6,800 share URLs, many opening without authentication.
- Samples included personal budgets, a bank‑fraud alert, a loan application, and confidential executive‑search prep.
- The exposure enables fraud, impersonation, and social‑engineering attacks.
- Meta suspended the sharing feature after the issue was reported by Ars Technica.
Researchers discovered that several HTTP/3 implementations allow a remote unauthenticated client to trigger massive memory allocation, leading to out‑of‑memory conditions. Seven of ten tested libraries are vulnerable, with patches released for quic‑go, Cloudflare quiche, and Wireshark.
Key points
- The flaw stems from missing or delayed decoded‑header size limits, allowing tiny HEADERS frames to expand into hundreds of thousands of header objects in memory.
- Affected implementations include quic‑go (CVE‑2025‑64702), Cloudflare quiche (CVE‑2026‑12523), Wireshark (CVE‑2025‑13945), lsquic, Bun, aioquic/mitmproxy, and hyperium’s h3 crate.
- Patches were released by October 20 2026 for quic‑go, Cloudflare quiche, and Wireshark; other libraries remain unpatched or have work‑arounds.
- Mitigations include disabling HTTP/3 in vulnerable servers or setting strict max‑field‑section sizes.
- IIS, Envoy, and ngtcp2/nghttp3 were not impacted by the tested vectors.

Storm-0940 employs AI‑powered ARTEX to hijack ConnectWise backup app credentials and exploit Okta self‑service registration, affecting hundreds of cloud tenants.
Key points
- Microsoft reported that Storm-0940’s ARTEX framework has been used against hundreds of organizations since September 2026, achieving privileged cloud access in under three hours.
- A stolen ConnectWise Cloud Backup app credential allowed the actor to sign into Microsoft 365 tenants as the app, assign Global Admin rights, and plant secrets in other apps, with no MFA prompt.

A threat actor has compromised nearly a thousand Magento stores with a persistent JavaScript loader hosted on deepveindrilling.com.
Key points
- Sansec’s research uncovered the deepveindrilling.com loader in the CMS block tables of 953 Magento shops, with 83 stores detected in a recent crawl and 148 installations over the campaign’s lifespan.
- The loader injects a script that reads a localStorage key, triggers stored code via an invisible div click, and collects detailed browser fingerprints to tailor responses.
- Two versions appeared in October 2026: an initial script referencing the domain directly, and a later inline loader that sends fingerprint data to the attacker’s server.
- The malicious code can write to the store’s database, and removal of the script does not revoke the attacker’s access.
- The campaign builds on earlier loaders tracked since July 2025, rotating domains and using the Keitaro ad‑tracking system to distribute payloads.
