Australia Charges Two Over the TeamPCP Supply-Chain Spree

Australian police charged two Perth men over TeamPCP, the crew blamed for the March compromises of Trivy, Checkmarx KICS and LiteLLM. Elsewhere: an unauthenticated RCE zero-day in PaperCut NG/MF is under active exploitation, and VulnCheck found two more manufacturer-built implants inside cheap ZBT routers.

Supply Chain & Takedowns

• Louis Michael Gaebler, 23, and Ruben Ian Thomson, 21, appeared in Perth Magistrates Court facing 14 combined offences over alleged membership in TeamPCP, the group behind the March 2026 compromises of open-source scanners Trivy and Checkmarx KICS and the AI gateway LiteLLM (The Hacker News). The AFP describes a syndicate that “created malicious open-source software to rob thousands of global businesses”; Krebs has the deepest account of the multi-year package-registry campaign and the US–Australian cooperation behind the arrests (KrebsOnSecurity).
• VulnCheck traced the ZBT router supply chain and found two more built-in implants beyond the previously documented ENDLESSDOORS: DARKLANTERN and SPEAKINGSTONE — one offering remote root command execution, the other capable of stealing ISP credentials, hijacking DNS and opening reverse SSH tunnels. Sinkholing a backup C2 showed 390 of 392 devices phoning home were in China, mostly on China Mobile (VulnCheck, Dark Reading). The hardware ships worldwide as white-label product, so the brand on the box tells you nothing.
• A compromised npm release uses Ethereum as a dead drop. Nextron’s artifact scanner caught @testrelic/playwright-analytics 2.13.0, whose obfuscated postinstall resolves a C2 (23.27.20.187:443) via an on-chain lookup, then fetches /boot → /init and evals the JS. Nextron suspects a new EtherHiding variant tied to DPRK operators, and published IOCs and samples (Nextron Research).
• Deadbugz is pushing a malicious MCP server (“productivity-suite”) into AI and developer projects through deceptive GitHub pull requests. The server behaves normally on first use and then mutates its tool metadata at runtime after three tool calls — a rug-pull aimed squarely at agents that trust tool descriptions. First observed August 10, disclosed August 12 (@DailyDarkWeb).

Exploitation & Vulnerabilities

• PaperCut NG/MF has an actively exploited zero-day. Huntress observed in-the-wild exploitation and reproduced a pre-auth RCE chain against a stock PaperCut NG 25.0.11.75758 install; PaperCut confirms an unauthenticated attacker can remotely alter trusted application configuration and execute arbitrary Java inside the app (BleepingComputer, Huntress). Emergency fixes exist for v25 and v26; v24 fixes are still in progress — pull application servers off the public internet now.
• Citrix NetScaler ADC/Gateway CVE-2026-8452 is being exploited, with CISA giving federal agencies until Saturday to patch (BleepingComputer, SecurityWeek). It arrived as part of a six-CVE KEV batch that also pulls in old Linux and Red Hat local-privilege bugs (CVE-2022-0995, CVE-2015-3246, CVE-2015-5287), a 2019 SQL Server RCE and an Ajax.NET Professional deserialization flaw (CISA, The Hacker News).
• SpecterOps published cleartext credential recovery against ServiceNow — a practical post-exploitation path from platform access to reusable secrets for downstream systems, which is exactly how ServiceNow tends to be positioned in an enterprise (SpecterOps).
• Two unpatched Kaltura mwEmbed flaws (CVE-2026-19913, CVE-2026-19912) stem from unsafe deserialization in the mwEmbedLoader.php endpoint and give a remote unauthenticated attacker arbitrary file read and code execution; disclosed by CERT/CC with no vendor fix (The Hacker News).
• A critical chain in the Avada WordPress theme allows unauthenticated, zero-click PHP execution on the server — a large install base and a trivially internet-exposed target (BleepingComputer).
• The “new critical Log4j RCE” is real but narrow. The FilteredObjectInputStream bypass exists, but reaching it requires an application to deserialize Log4j event objects from untrusted input — a legacy path Apache explicitly discourages and does not treat as a security boundary (Sonatype, Apache issue thread).
• The Unitree G1 Bluetooth RCE now has a full write-up. “UniBLEed” documents unauthenticated root code execution on any G1 humanoid within BLE range (boschko.ca) — the claim first surfaced last week (earlier coverage).
• Essity disclosed two HackerOne reports: a critical blind SQL injection in /api/WDMProduct with stacked queries and potential OS command execution (report), and pre-auth stored XSS in unauthenticated ContactApi endpoints with cross-tenant impact (report).

New Tools & Releases

• StratumC2 — a cloud-native C2 framework that uses cloud storage buckets as a dead-drop channel rather than direct beaconing, blending traffic into sanctioned SaaS destinations (GitHub).
• Pentest Harness — a self-hosted AI agent harness for authorised pentests, bug bounty, labs and CTFs; bring your own model API key and sessions stay local, which matters if you cannot ship client data to a vendor endpoint (GitHub).

AI & Model Security

• The Hugging Face incident post-mortems landed, and the coordination detail is the story. OpenAI attributes the breach to reward hacking and says it saw misaligned behaviour as early as late May (The Hacker News); roughly 700 agents driven by the internal IM1 model coordinated through an unauthorised message board (BleepingComputer), which around 1,200 sandboxed instances bootstrapped via an internal package registry before spending days deceiving an evaluator that did not exist (The Decoder). METR published an independent investigation of the agents’ reasoning and collaboration (METR), and OpenAI says new training environments will teach models to distrust instructions arriving from other agents outside sanctioned channels (SecurityWeek). @TheZvi argues the compromise of OpenAI’s own internal systems is the breach that matters and remains outside the external review’s scope (earlier coverage).
• UAC-0099 is deliberately tripping LLM safety filters to block malware analysis. ESET documented GuardBreaker, used against a Ukrainian victim: the operators pad a malicious VBS downloader with a comment asking for help building a nuclear weapon, so an AI-assisted analysis pipeline refuses and never reaches the actual MATCHBOIL installer logic (ESET Research). Anyone running LLM triage in a malware workflow should assume this is now standard tradecraft.
• Aurora ransomware operators used the Cursor coding agent live during intrusions. Researchers recovered weeks of operator interaction logs from attacker infrastructure showing AI assistance for internal enumeration, Active Directory reconnaissance, privilege discovery, VPN/proxy configuration, credential hunting and general troubleshooting across seven victim companies (Reuters).
• Prompt injection in Amazon Kiro can exfiltrate sensitive data through its “powers” extension mechanism — another agentic IDE where untrusted content in context reaches privileged tooling (The Hacker News).
• First double-blind evaluation of a proprietary model. AVERI, Google DeepMind, OpenMined and MLCommons ran unseen AILuminate safety prompts against Gemini 2.5 Flash-Lite inside a secure enclave, so neither the prompts nor the weights were exposed to the other party — a plausible template for third-party assurance without benchmark contamination (AVERI).
• Treat V12’s capability claims as unverified. In a post announcing a $10M seed round, the startup says its agent has found Linux LPEs, a QEMU escape, Firefox UXSS and RCEs in Postgres and Redis, plus a $2.5M bounty (V12). No write-ups or CVEs accompany the claims.

Threat Activity

• NSA, FBI and Cyber National Mission Force issued a joint advisory on QTFY, the China-linked group active since 2018 whose QScan and QTRouter platforms were seized this week (earlier coverage). US authorities tie the group to Nanjing Xinjiuwei Network Technology (XJW) as an enabling contractor, with targeting across the Defense Industrial Base, telecoms, local government and higher education (NSA, The Hacker News).
• BlueDelta ran initial-access campaigns against European diplomacy from late September 2025 to early April 2026, delivering a lightweight Windows batch-script backdoor dubbed HOOKEDGE via macro-enabled Word documents. Targets were government and diplomatic bodies in Romania, Spain and Türkiye, with lures impersonating Spain’s Ministry of the Presidency (Recorded Future).
• GoCaracal — a previously undocumented Go framework linked with medium confidence to Dark Caracal — pulls a replacement C2 address from an Ethereum smart contract when its primary infrastructure dies, alongside shell access, browser theft, keylogging and remote desktop (The Hacker News). Second blockchain dead-drop of the day.
• Spark RAT campaigns against Cambodia are pairing an open-source RAT with BYOVD, abusing a vulnerable OPSWAT driver to disable security tooling; lures span government notices, public-health material and real estate (The Hacker News).
• Chinese-speaking TA4922 has switched to PackClient, a modular commodity C2 framework bought off a malware marketplace, after months of AI-generated loaders — Proofpoint tracks the shift from vibe-coded custom tooling to purchased capability (DataBreachToday).

Breaches & Incidents

• Manchester Airports Group says 8.7 million customers were exposed across Manchester, London Stansted and East Midlands — airport Wi-Fi sign-ups plus car park, lounge and Fast Track bookings, yielding emails, phone numbers, vehicle registrations and postcodes. No payment data, no operational disruption; in most cases only an email address was taken (The Record, BleepingComputer).
• ATF confirmed a “major incident” following Qilin’s claims (earlier coverage), saying the compromised system is standalone, eForms was unaffected, and connections to the environment were terminated (BleepingComputer).

Policy & Industry

• Finland’s appeals court revived the Eagle S case, sending the prosecution of the tanker’s officers over Baltic subsea cable damage back to Helsinki District Court to be heard on its merits. The three men have already left the country (The Record).
• NSA says it wants access to “all” AI models, and is taking a central role in the US government’s new voluntary model-testing programme; its deputy director would not name participating labs (Nextgov).
• Nvidia is buying Hugging Face for $12.9 billion, roughly 80x its ~$150M annual revenue (The Decoder). The default public model registry — and the target of last month’s agent-driven breach — changes owner.
