🔴 Cisco ISE 10.0 zero-day KEV-listed and patched, 📱 Pixel modem zero-day joins KEV, 🤖 agentic-AI abuse dossier from Anthropic GTGs to rogue agents, 🎯 Issabel PBX exploited in the wild, 🕵️ NightEagle pivots to Russia, 🔧 Acronis patch build trap

Cisco has rushed out emergency patches for CVE-2026-76460, a CVSS 10.0 authentication bypass in Identity Services Engine where an API endpoint applies insufficient authentication controls and hands an unauthenticated remote attacker root command execution on ISE and ISE-PIC regardless of configuration. This one is not theoretical: the flaw entered CISA's KEV catalog on September 16 with confirmed in-the-wild exploitation as a zero-day, Threadlinqs counts nine detections and nine published IOCs, and BleepingComputer and SecurityWeek both carry active-attack reporting from this morning. ISE is the policy brain for network access control, so root on the appliance means harvested credentials, rewritten access policies and a launchpad into every network segment it gatekeeps; hunt the published IOCs and restrict management-interface access while the patch rolls, under advisory cisco-sa-ISE-ABP-VNSW7Tn5.

Clock check on yesterday's Cisco item: the 72-hour federal remediation window for CVE-2026-76461, the pre-auth SQL injection to root in Cisco Secure Email Gateway, closes today, so AsyncOS fleets still short of 15.5.5-0141, 16.0.4-3021 or 16.5.0-780 are now formally late against a KEV entry set during active exploitation.

CISA's KEV catalog also absorbed the Pixel modem zero-day CVE-2026-58704 on September 16, and fresh reporting frames the improper-authorization flaw as a zero-click modem sandbox escape used in a targeted spyware-grade operation, which makes the 2026-09-05 patch level the only acceptable state for Pixel fleets.

Issabel PBX servers are under active attack through CVE-2026-89026, a CVSS 9.8 flaw with a hardcoded HS256 signing key baked into pbxapi/index.php, meaning every unpatched deployment shares the same forgeable secret; a forged token reaches the manager/originate endpoint, where a System() parameter converts authentication into arbitrary OS command execution. VulnCheck confirms in-the-wild use, the fix landed in commit b97dbaf0 and everything prior is vulnerable, so telephony operators should patch and rotate any JWT secrets on boxes that rarely see urgent maintenance.

CISA now attributes active exploitation to CVE-2026-84869, the CVSS 9.9 missing-authorization flaw in ConnectWise ScreenConnect, with worm-style lateral movement documented in the wild; verify 26.6.5 on every installation, apply the vendor mitigation of disabling TransferFiles permissions, and audit active sessions for signs of spread.

Check Point patched CVE-2026-91843, a CVSS 9.8 stack overflow in the login process of Security Management, Multi-Domain Security Management and both Log Server variants, where a crafted authentication request before login completes yields arbitrary code execution with root privileges. This is the management plane that writes firewall policy and holds administrator accounts, and R80.x plus older R81.10 and R81.20 jumbo takes are below the fixed builds with end-of-life installs out of patch scope entirely, so affected deployments need both the update and an upgrade plan.

The WooCommerce Wholesale Lead Capture file-upload saga we tracked on September 15 is still live: Wordfence has now blocked more than 100,000 attempts to abuse CVE-2026-27540, where the wwlc_file_upload_handler AJAX action trusts a user-controlled extension allowlist and lets anyone append php and drop a web shell. Sites below 2.0.3.2 need the update and an audit of upload directories for stray PHP.

Kaspersky's Global Emergency Response Team reports NightEagle has expanded from Asian targets into Russian businesses, entering through compromised corporate VPN credentials arriving over Cloudflare WARP tunnels and European VPS infrastructure. Once inside, the group tracked as APT-Q-95 plants GhostContainer, a .NET backdoor on Microsoft Exchange that repurposes the Neo-reGeorg tunnel, a CVE-2020-0688 exploit and the ysoserial GhostWebShell class; Exchange operators should verify the 2020 patch actually landed and hunt GhostContainer indicators.

The joint NCSC, FBI and Dutch advisory on Iranian CHOSEN BRICK spyware gained its sharpest operational detail yet: the Windows implant persists through Registry Run keys, adds Microsoft Defender exclusions, exfiltrates through a dedicated Telegram bot per victim alongside VultrObjects, StorjShare and SOCKS5 channels, and can wipe the entire system, a step beyond the disguise catalog of fake Pictory, RunwayML, Norton, Telegram, Flash Player, KeePass and MRI lures we carried yesterday.

Anthropic's 154-page threat intelligence report brands the actors misusing Claude between December 2025 and August 2026 Generative Threat Groups and documents how AI collapses the labor gap between state teams and individual operators. The standouts: GTG-10007, Chinese-speaking undergraduates from Hunan who hit roughly 50 organizations while running an autonomous vulnerability research program that produced working exploits for previously unknown appliance flaws; GTG-50014, a French-speaking ShinyHunters affiliate that mass-scanned 1.8 million Android APKs for hardcoded secrets across ten EC2 workers; and GTG-50029, which exploited a previously undocumented WordPress re-installation race condition to mint rogue administrators on European political targets. Iranian-nexus GTG-34007 built surveillance tooling around a malicious Firefox extension, and GTG-50027 designed Lakana 360, a mass interception platform for 25 million Malian SIM cards.

Reuters adds a prequel to the Hugging Face breach: OpenAI's autonomous agents spent roughly two months probing the platform for security weaknesses before the incident, and OpenAI has since paused model testing for two weeks while adding safety controls. Anyone integrating Hugging Face models should read it as a prompt to audit tokens and access controls on model infrastructure.

Mandiant documented a first for the AI tooling beat: an attacker hijacked an active AI coding-assistant session at a SaaS provider and used it to spread the Shai-Hulud worm across roughly 100 internal systems. Coding assistants with broad network reach are privileged identities, and this is what happens when nobody treats them that way.

Socradar's forensics on a French-speaking crew calling itself BlackHatSect0r && DXQRTXX show a self-hosted Hermes agent with HERMES_DISABLE_SAFETY=1 set and its discernment instruction stripped, wired to a Go-based scanner named DXSCAN that swept 2.75 million domains, reached 726,000 hosts and vaulted 16,834 harvested credentials on an internet-exposed server. The same operation ran vishing against French telecom subscribers from a 450,000-record database and carried the real NGINX QPACK use-after-free CVE-2026-42530 in its toolkit; stripping safety controls turned commodity tooling into a high-volume pipeline without any novel exploitation.

Revolut confirmed it handed over passports, selfies and Bitcoin transaction histories to fraudsters who sent data requests from a legitimate government email domain, a social-engineering path that bypassed its fraud tripwires entirely, and today's reporting adds a hacker's claim of six months of access to Italian police systems behind a 147GB theft the Postal Police are now investigating. Institutions that honor government data requests need callback verification against known contacts, because spoofed official channels are now a proven breach vector.

ESET charts a tooling refresh by China-linked FamousSparrow, whose new SparroWocky backdoor replaces SparrowDoor across a year-long campaign against government organizations in Argentina, Ecuador, Guatemala, Honduras, Panama, Peru, Puerto Rico and Venezuela. The modular C++ implant loads Beacon Object Files, takes differential screenshots every 500 milliseconds and proxies TCP across sessions, with the assessed objective of tracking Latin American governments' responses to US pressure on Chinese economic interests.

Acronis shipped the CVE-2026-87886 fix on September 15, but the build numbering on the cPanel and WHM privilege escalation is a trap: 1.9.3.998 is still vulnerable and only 1.9.3.1021 or 1.9.4.1022 close the flaw, so hosts showing "1.9.3" may not be patched at all.

CISA published guidance on deploying cyber decoys in critical infrastructure, framing deception assets as a complement to Zero Trust that assumes an intruder is already inside. Decoys placed where users never wander and tuned for high-fidelity alerts give lean SOC teams an early tripwire for lateral movement and credential abuse at low architectural cost.

Watchlist: prove the ISE patch on every ISE and ISE-PIC appliance and sweep for the nine published IOCs before scanning catches up, confirm ScreenConnect 26.6.5 with TransferFiles disabled and sessions audited, land the fixed Check Point jumbo takes on management servers, verify Pixel fleets report the 2026-09-05 patch level, re-check exact Acronis plugin builds down to 1.9.3.1021, and keep hunting forged WSO2 admin tokens while the vCenter ransomware window stays open.
