Three Chained Zero-Days Put Root on a Fully Patched Ivanti VPN

Volexity documented an actor it tracks as UTA0576 chaining three Ivanti Connect Secure zero-days for unauthenticated root, and only two have fixes. Elsewhere, Microsoft shipped the largest Patch Tuesday on record, Kim Zetter reported hardware implants in Trezor wallets as well as Ledger’s, and Denmark’s national person register turned out to have been reachable behind the password 123456.

Vulnerabilities & Exploits

• Ivanti Connect Secure is under active in-the-wild exploitation via CVE-2026-104935, an authentication bypass plus race-condition RCE chained with a separate privilege-escalation bug to reach root. Volexity says UTA0576 hit a fully patched 22.8R2.4 appliance on 3 October 2026; notably the actor deployed no web shell or backdoor, going straight for credential theft and data exfiltration (Volexity, Ivanti advisory). Ivanti has patched two of the three; a fix for the third is still pending per Volexity (The Hacker News). CISA added it to KEV the same day (CISA); NCSC-NL notes no public PoC yet but expects one shortly (NCSC-NL). @watchtowrcyber says it is actively notifying platform clients of exposure. (discussion)
• Microsoft’s October Patch Tuesday is the largest ever shipped: 1,411 fixes per BleepingComputer, 1,415 per Talos, 1,417 per the ISC — one actively exploited, two publicly disclosed (BleepingComputer, SANS ISC). The exploited one is CVE-2026-96951, a Windows Shell command-injection security-feature bypass (CVSS 8.8, user interaction required), now in KEV with a BOD 26-04 federal due date of 16 October 2026. Talos flags CVE-2026-70229 (AD Domain Services RCE, 8.1) and CVE-2026-70571 (Exchange stack overflow, 8.1) as “exploitation more likely”, plus CVE-2026-100202 in MSMQ at 9.8 (Talos). Windows 11 24H2 Home and Pro are now out of support (BleepingComputer).
• A public exploit is out for FortiClient EMS pre-auth bypass CVE-2026-35616 (CVSS 9.8, affecting 7.4.5–7.4.6, fixed in 7.4.7). The flaw is improper access control around client-certificate auth: forged certificate-related HTTP headers reach protected API functionality. The released tool enumerates usable certificate identities and tests protected endpoints (exploit repo).
• Docker Hub patched a two-year-old critical token-impersonation flaw, CVE-2026-105445. Converting a personal account into an organization reassigned that account’s PATs to the named new owner without rotating the secret or asking consent, letting an attacker’s token act as the target at registry level — pull, push or delete in the target’s repos. Introduced 26 August 2024; reported 30 September 2026 and fixed in production under four hours. Docker found no evidence of exploitation after reviewing 304,000 pushes made with transferred tokens (BleepingComputer, Docker advisory).
• GitLab’s CVSS 10.0 CI/CD regex flaw now has Nordic CERT advisories behind it. CVE-2026-97229 is an integer overflow in the CI/CD regular-expression compiler allowing unauthenticated arbitrary code execution on the server; all versions from 19.2 before 19.2.8, 19.3 before 19.3.5 and 19.4 before 19.4.2 are affected. CERT-SE urges urgent patching for internet-exposed instances and log review for signs of intrusion (CERT-SE, CERT.dk) (earlier coverage).
• SAP patched a CVSS 10.0 OAuth2 SSRF in the Cloud SDK for Python (CVE-2026-89111, fixed in 0.45.2): an attacker who controls the tenant_subdomain parameter in multi-tenant BTP apps can redirect OAuth2 token requests to their own server and exfiltrate client credentials. Workaround is an allowlist of registered tenant subdomains. Also critical: CVE-2026-89110 (NetWeaver Visual Composer broken access control, 9.9) (BleepingComputer).
• Ghostscript heap overflow CVE-2026-39919 allows RCE through crafted PDFs — relevant anywhere a server-side pipeline accepts user-uploaded documents (BleepingComputer).
• Three webOS flaws chain to pre-auth root on LG smart TVs from the local network, with no PIN or owner interaction. Tested on the 32LQ636BPSA and 27TQ600SW running webOS 7.5.7-25; LG has issued a fix per SSD Secure Disclosure’s 12 October advisory (The Hacker News).
• Visual Studio Copilot and SSMS RCE (CVE-2026-103572) came from Windows filename canonicalization: trailing dots, traversal and malicious config files defeated path validation (Embrace The Red).
• A PoC is public for Hyperledger FireFly SSRF CVE-2026-82957 (CVSS 8.5, ≤ 1.5.0): webhook subscriptions accept a user-controlled URL without validating the destination host, reaching internal services, loopback and cloud metadata endpoints (PoC repo).
• An AI fuzzing run found a critical Adobe Reader zero-day, CVE-2026-81983 — an integer overflow leading to an out-of-bounds write, surfaced in roughly a week of automated fuzzing (Remedio). Adobe’s October bundle separately covers 176 flaws across 11 products (SecurityWeek).

Offensive Tradecraft & Research

• A Pwn2Own Automotive write-up details a 0-click RCE chain against the Alpine iLX-F511 head unit, published in full by the researcher who landed it (write-up).
• Windows Fibers are being used to run arbitrary code inside an existing thread, with no new thread creation — a thread-creation-free execution primitive that sidesteps a common detection anchor. @ipurple ties the technique to Earth Ammit and Earth Kurma activity involving CoffeeLoader and ACR Stealer against government and technology targets in South Korea, Taiwan, the Philippines, Vietnam and Malaysia.
• DLL injection via SetWinEventHook — using the accessibility hook as the injection vector — is walked through by Pavel Yosifovich (TrainSec).

New Tools & Releases

• Strands Box is an open-source sandbox for AI agents, pairing OS-level isolation with semantic policies written in Dogwood so you can constrain what an agent reaches and under what conditions (GitHub).
• Visor is an open-source Android app built from a reverse-engineered Ray-Ban Meta glasses-to-phone protocol, letting “Hey Meta” route to Claude or a self-hosted model instead of Meta AI — useful as protocol documentation as much as a client (GitHub).

Supply Chain

• Trezor wallets have also been found with hardware implants, despite the company’s public statement. Kim Zetter reports that hardware hacker Joe Grand found implants in a Trezor One and a Trezor Model T and notified Trezor in August — so Grand “was surprised today” to see Trezor say publicly it is not aware of any compromised devices. The Trezor units came via non-authorized third-party sellers, unlike the Ledger devices sold through authorized resellers (Zetter Zero Day) (discussion).
• Ledger published its Donjon analysis of the implant, found in a signer sold by Southeast Asian reseller CryptoBilis: a hidden component whose microcontroller reads and decodes the 24-word recovery phrase off the screen during setup, then transmits it over LTE via a provisioned eSIM (CoinDesk). Losses linked to the implant are now put at $86 million (SecurityWeek). Ledger has told resellers across seven Southeast Asian markets to suspend sales, and MediaMarktSaturn pulled Ledger products from all its countries as a precaution (Cointelegraph) (earlier coverage).
• npm Trusted Publishing bindings were reclaimable via GitHub slugs. Bloom Security’s SlugFest research found that before a binding’s first successful publish, npm stored the GitHub owner/repo slug rather than an immutable repository ID — so anyone who reclaimed a renamed, transferred or deleted slug could mint a short-lived publish credential for packages still trusting that path. Bloom identified 1,500+ packages with unvalidated Trusted Publisher configs. GitHub now expires unvalidated configs after 48 hours and rejects trusted-publishing tokens from issue_comment events (The Hacker News, Bloom Security).
• A trojanized PuTTY MSI is being distributed through SEO poisoning, installing a Node.js loader alongside a legitimate signed PuTTY GUI as a decoy. The C2 address is resolved via EtherHiding (blockchain-hosted), and the operator pushes JavaScript for recon, exfiltration and live screen streaming (Unit 42).

AI & Model Security

• Anthropic’s self-replication study is the concrete version of the “AI worm” question. Researchers gave small models roles on cheap Android TV boxes with unauthenticated ADB exposed: Qwen3.5-9B installed and configured the software to run Llama3.1-8B on eight of the nine hardware types tested, and GLM-5.2 reached all eight nodes in an emulated network in four of five trials. Retaining data from previous attempts raised Qwen3.5-9B’s success rate from 45% early to 84% in later generations; using Opus 4.8 as an advisor produced no measurable improvement. Critically, they did not demonstrate a fully autonomous self-replicating worm on real IoT hardware — the projection is that ≤30B-parameter models could reach that bar by end of 2026 (BleepingComputer, Dark Reading). HN commenter evan_a_a points to Anthropic’s own write-up as the thing to read rather than the coverage. (discussion)
• Model backdoors are cheap to plant and hard to remove reliably — new research argues standard fine-tuning and safety training leave triggers recoverable, which matters for anyone consuming third-party weights (Equistamp).
• A network-filtering flaw in Vercel Sandbox gives agents a data-egress path. AI security startup AIR found agents could abuse certificate-validation handling to transmit data outside approved networks — an escape from the isolation layer that agent platforms depend on (The Record).
• Anthropic says it cut extraction of Claude’s internal reasoning tokens by 90–99%, attributing the industrial-scale distillation attempts to Chinese firms Zhipu and Moonshot, and says it has banned tens of thousands of accounts (The Decoder).
• Google shipped Gemini 4 Argon worldwide via API, the Gemini app and Antigravity — priced aggressively but trailing Claude Opus 5.5 and Muse Wonder Full in independent benchmarks (The Decoder).
• Character.ai filed voluntary Chapter 11 and will shut down if no buyer emerges by end of 2026 (Character.ai, The Verge) (discussion).

Threat Activity

• The French refrigeration attacks have expanded beyond Danfoss. CERT-FR revised alert CERTFR-2026-ALE-012 on 13 October to add Copeland xweb and Dixell xweb controllers alongside Danfoss AK-SM/AK-SC, and says attacks are probably still ongoing. Attackers raised temperatures to 50°C overnight on 11 October across hundreds of stores including Carrefour, Auchan and Les Mousquetaires chains, forcing mass disposal and millions of euros in losses (The Hacker News, SecurityWeek). Claroty Team82 separately published vulnerability research on the Danfoss controllers (Claroty) (earlier coverage).
• Ahold Delhaize is still degraded globally. The company began a controlled relaunch of certain systems and says it has “no evidence at this moment” customer or associate data was taken; US web and app ordering for Stop & Shop, Giant, Food Lion and Hannaford remain offline, as do Albert Heijn and Etos services in the Netherlands (Ahold Delhaize, Kevin Beaumont).
• DoJ raided 40+ Texas residences and seized ~187 devices in Operation Lonestar Roundup (21–25 September), charging 14 people. US nationals Michael James Bostelle and Juan Cecilio Pena Carrillo allegedly helped North Korean workers earn over $3 million from about 70 US companies across 17 states, including healthcare, cybersecurity, retail and manufacturing firms (The Record, DoJ).
• Kimsuky is reply-baiting Ukrainian diplomacy and security experts. Genians documents fake conference invitations with genuine event details and no malicious payload in the first message — the attachment only arrives after the target replies — plus fake PDFs and Zoom installers. Likely collection targets include North Korean troop losses and the handling of captured soldiers; most observed attempts failed. Japanese-language documents on the same infrastructure suggest planned Japanese targeting (The Record, Dark Reading).
• XWorm has grown from infostealer into a surveillance platform, with an expanded plugin set covering location tracking, live audio streaming and interaction with authenticated browser sessions (Netskope Threat Labs, SecurityWeek).
• The ShinyHunters name is now contested by multiple factions. A new actor calling itself Hasanbr0ker claims leadership after the previous figurehead’s arrest, a “ShinyEquationCartel” claims a core drawn from ShinyHunters, LAPSUS$, HellCat and LockBit, and a group using the name is advertising a RaaS programme with an 80/20 split and a $1,000 joining fee. All claims are unverified (Catalin Cimpanu, FalconFeeds).
• TFG London was hit on 11 October, with IT systems behind Phase Eight, Hobbs and Whistles affected and several still unavailable; White Stuff, Inside Story and TFG’s Africa and Australia operations run separately and are unaffected. Reported to UK authorities (JSE SENS filing, BleepingComputer).
• Preinstalled firmware malware on low-cost MediaTek-based Android phones is turning devices into residential proxies and running covert app installs and ad fraud; Bitdefender tracks it as Midnight Mimosa (The Hacker News).
• Meta disclosed a GitHub breach in which attackers took source code and personal data on roughly 1,500 employees (SecurityWeek).

Nordics & Europe

• Denmark’s CPR breach traced to the password 123456. The person claiming responsibility told Politiken they reached the Central Register of Persons through an IT company account protected by that password, and the paper reports at least three company accounts — including an administrator account — shared it. Access began 10 September, with 14 million automated searches run through 20 September; the intrusion was not detected until 2 October, 12 days after the last search, when a staffer noticed an unusually large invoice from supplier Pays ApS. Data on 8.8 million people was accessed from a register of roughly 11 million records (The Register) (earlier coverage).
• Norwegian military personnel found that rented Chinese-made cars automatically recorded and stored video during exercises — a vehicle-telemetry angle on operational security that applies well beyond Norway (Catalin Cimpanu).
• The main contractor on the Danish–German Fehmarnbelt tunnel was hit by a cyber incident. Femern (Sund & Bælt) confirmed the incident at Femern Link Contractors on 13 October; local reporting says central systems were disabled and work on the multibillion-kroner project significantly disrupted. No attribution, affected systems or outage scope disclosed (Femern).
• Polish prosecutors say Pegasus-collected data left Polish territory and NSO Group may have had access to the processing and storage infrastructure. The ABW analysis found the Central Anti-Corruption Bureau lacked full control over the system; PM Donald Tusk called it a crime against the state (UA.News / Anadolu).
• Three French teenagers were arrested over Reacher, a platform launched in March that let users search hacked and stolen data (Catalin Cimpanu).

Industry & Law Enforcement

• An OpenAI engineering lead was arrested over a hidden recorder in an executive conference room. Abdulrahman Alfozan, 35, a Saudi national employed since July 2025, was arrested 9 October and charged with endeavoring to intercept oral communications. OpenAI staff found the device on or around 30 September — wrapped in toilet paper and plugged into a USB port behind a television — installed around 28 September; CCTV allegedly showed Alfozan near the room on multiple dates despite having no authorization to be there. He has been terminated (The Hacker News, DoJ).
• An NCA-hosted Joint Disruption Week produced 28 arrests across West Africa (19 in Ghana, 9 in Nigeria), $11 million seized and 3.7 million accounts suspended with private-industry partners including Meta. In Ghana, authorities identified 117 human-trafficking victims pending repatriation and seized hundreds of devices (The Record, DoJ).
• The FTC obtained a temporary halt against Digital Forensics Corporation and its CEO, alleging the firm took at least $60 million from sextortion victims for “assistance services” — $1,499 to $20,000 per “Phase 1” package covering extortionist tracking, an investigative report and police reporting — that in many cases were never performed (The Record, FTC).
