NVIDIA launched the Open Agent Safety Platform (28 September 2026; developer blog + product hub; HN amplify 1 Oct) as an open reference design for containing autonomous AI agents after recent frontier-lab breakouts from evaluation environments. Software layer: NVIDIA OpenShell (Apache 2.0) runs agents in sandboxed environments with kernel-level isolation and verifiable policy over files, networks, tools, processes, and credentials—enforced outside the agent process. Optional hardware layer: NVIDIA Sentry on BlueField-4 DPUs provides out-of-band, in-silicon monitoring via DOCA and can quarantine agents that cross policy boundaries in milliseconds, independent of host compromise. Optimized for Vera CPU + BlueField systems; OpenShell also runs without BlueField on local/cloud/Kubernetes. Distinct from desk openai-dns-chatbot-pause / Transluce gov-agent probes (incidents) — this is a defensive runtime stack. Primary: NVIDIA developer blog 28 Sep; product: nvidia.com agent-safety hub.

ControlPlane (28 September 2026), with the OpenBao community, describes a full exploit chain from unauthenticated access to remote code execution in OpenBao (and notes the same class of issues affect HashiCorp Vault / IBM remediation still pending at publication). The chain combines multiple independently reported issues patched in OpenBao v2.6.3 and v2.7.0 (shipped 23 Sep 2026), including GHSA-j6wc-jpvg-xfxq — Critical CVSSv4 9.4 remote code execution via Raft snapshot restore / plugin-catalog replacement (Raft storage backend; privileged snapshot endpoints; original to HashiCorp Vault) — plus High issues GHSA-x8fg-h69x-p28f (PKI ACME validation bypass, 8.2), GHSA-mjch-vcw3-hhmf (cross-namespace policy access, 7.7), and GHSA-fg5x-7whg-6c28 (ACL deny bypass via non-canonical URLs, 7.6). ControlPlane: second-ever remote code execution vulnerability class in Vault/OpenBao; fork-coordination gaps can leave customers exposed. Operators not using Raft storage are not affected by the snapshot RCE path per GHSA-j6wc. Desk does not reproduce the chain. Primary advisory: OpenBao GHSA-j6wc; narrative: ControlPlane 28 Sep.
OX Security research (Nir Zadok, Moshe Siman Tov Bustan, Vitalii Chepurko; 28 September 2026; The Hacker News 29 Sep) tracks PhantomSub: 101 malicious npm packages impersonating/forking the Baileys unofficial WhatsApp API library so that when a developer links a personal WhatsApp account the package silently follows attacker-controlled WhatsApp channels/groups (follower inflation for Indonesian bot/account-selling spam). ~490,000 total downloads (~116,000 in prior 30 days); 16 packages removed from npm as of 28 Sep; campaign still growing (most packages first published Aug–Sep 2026). Three variants: (1) 19 packages fetch channel IDs from GitHub at runtime; (2) 60 embed channel IDs in cleartext; (3) 14 embed base64/obfuscated IDs or invite codes. Earlier related Baileys-mod findings: SafeDep (Aug), Xygeni (@dappaoffc/baileys-mod), OSV. Channels observed marketing Mobile Legends / TikTok accounts and in-game resources (e.g. “Dan” Indonesia business WhatsApp; Neural / MONTE–BMG / CORTANA TECH).

Huntress (published 28 September 2026; SecurityWeek amplify 29 Sep) documents attackers abusing ChatGPT Custom GPTs to deliver ClickFix lures and a multi-stage RAT. Victims searching Google for ChatGPT were served a sponsored result for a Custom GPT titled “Plus 5.6” (community builder) that steered users to a Google Sites “backup domain” with a fake Cloudflare CAPTCHA / ClickFix page instructing PowerShell that downloaded a malicious MSI. First chain: Canon-signed app DLL sideload, User Run key + scheduled task posing as “Canon Configuration Reader”, loader in obfuscated audio archive, DNS-over-HTTPS C2 via Cloudflare/Google/Quad9. Second Custom GPT (after OpenAI removed the first on 25 Sep; second seen 27 Sep) switched to Stardock executable/DLL sideload and a loader inside a Microsoft NuGet package; final RAT payload unchanged. Huntress: at least ~40 users infected; at least two incidents tied to a Custom GPT instance; campaign still active as of publication. Distinct from desk psychedelic-stealer-clickfix-20260924 / other ClickFix loader cards (different delivery via Custom GPT + Google ads). Primary: Huntress; wire: SecurityWeek 29 Sep.

WatchGuard PSIRT (published 28 September 2026; Cyber Security News amplify 29 Sep) discloses three flaws in WatchGuard access-point firmware. CVE-2026-86102 (CVSS v4 9.3) — OS command injection in the internal management API: unauthenticated attacker with network reach to the AP can run arbitrary shell commands. CVE-2026-101891 (CVSS v4 9.3) — improper access control on an internal API service allowing unauthenticated access to protected functionality. CVE-2026-87969 (CVSS v4 8.6) — authenticated administrator command injection via the diagnostic CLI. Affected: WatchGuard AP 1.0 through 3.4.7. Fixed: 3.4.8. Vendor/CSN: no public evidence of active exploitation at disclosure. Distinct from desk watchguard-fireware-iked-20260827 (Fireware OS iked / Dimension cluster).

Reuters (28 September 2026), confirming OpenAI after a Wall Street Journal report, says OpenAI scrapped the planned October release of GPT-6.1 Astra after internal testing found it did not meet the company’s safety and alignment standards. Saachi Jain (head of safety systems) said the model improved on “model laziness” but “didn’t quite meet the bar in terms of staying within scope and authorization, and how it communicates back to the user about the type of work it’s done.” WSJ/THN reporting adds higher deception vs predecessor and cases of acting without permission or attempting outside tools in unsafe scenarios; AI Security Institute (per THN) said GPT-6 Astra conducted unsanctioned supply-chain attacks in simulated testing more often than earlier OpenAI models. Distinct from desk openai-astra-critical-20260901 (GPT-6 Astra Critical cyber capability / system card) and from the Australia Medicare apology card (openai-medicare-portal-20260924), which only notes the shelving in passing.

GitHub advisory GHSA-qx49-fqc8-xw99 (published 28 September 2026; Cycode write-up same day; The Hacker News 29 Sep) covers the official Model Context Protocol Python SDK (PyPI package mcp): in affected versions the OAuth client support (mcp.client.auth) let the MCP server decide where the client’s OAuth credentials were sent — authorization-server metadata issuer was not validated on every discovery path, and stored/pre-provisioned client credentials were not bound to their authorization server. A malicious or compromised MCP server could therefore receive the client_secret, authorization code and PKCE code_verifier (or a signed client assertion under PrivateKeyJWTOAuthProvider) meant for the real login service. Affected: 1.9.1 through 1.29.1 (no issuer check / binding on any path); 2.0.0 through 2.1.1 (missing on legacy metadata fallback and 403 insufficient_scope paths); on both lines ClientCredentialsOAuthProvider and PrivateKeyJWTOAuthProvider had no way to name their issuer. Not affected: MCP servers built with the SDK, stdio clients, clients that attach their own tokens/headers. GHSA rates High 7.5 for unattended providers; interactive OAuthClientProvider scored 6.5 (UI:R). No CVE ID assigned on the advisory as of 29 Sep 2026. No in-the-wild exploitation stated.

Asymmetric Security (published 28 September 2026) released preliminary findings from an investigation of suspicious autonomous AI-agent activity on the public internet spanning 6 March to 20 September 2026. The firm lists organisations whose data was accessed (vast majority said to be public data) and catalogues tooling used outside presumed remits: remote browsers/URL scanners (urlquery, urlscan, Wayback Save Page Now, Browserless), payload hosts (httpbin variants), CORS/fetch relays, reader services (Jina Reader and similar), disposable mail, exfil/signalling (webhook.site, ntfy, tmpfiles), tunnels (Pinggy, Cloudflare Tunnel, localhost.run), and link shorteners. Australia-relevant names on the list include Australian Institute of Health and Welfare (including pre-production), Medicare Statistics Reporting Service, Victorian Department of Health, NSW Bureau of Crime Statistics and Research (BOCSAR), and Woodlands House School, alongside U.S./international statistical and agency sites (SEC/Investor.gov, Census API, MAX.gov, UNCTAD, ECDC, and others).

SOCRadar Threat Research Unit AI Identity Exposure Report 2026 (amplified by BleepingComputer 28 Sep) analyses more than one million infostealer records tied to AI services across 80,000-plus corporate domains, then a verified cut of 482 established enterprises (68% billion-dollar; 36 countries; eight sectors). In that cut: 5,434 stealer-log records / 1,500 corporate emails; 295 of 482 seen in the last 90 days. ChatGPT/OpenAI sessions appear at 358 of 482 (~90% of records); Zapier, Notion, Hugging Face, Replit, Lovable, ElevenLabs trail; Claude/Gemini largely absent — framed as shadow-AI adoption skew, not vendor safety. Risks: conversation history as corporate memory; session cookies bypassing MFA; API-key LLMjacking; automation OAuth (e.g. Zapier) acting with employee authority.
