All news with #supply chain compromise tag

🛡️ At Dreamforce, Salesforce emphasized shared responsibility for securing customer environments and introduced new AI agents for security and privacy. The conference largely avoided discussion of recent OAuth-based supply-chain breaches that exposed data from hundreds of companies and led to extensive litigation. Analysts warn the incidents — driven by compromised tokens from third-party apps like Salesloft Drift and spoofed tools such as malicious Data Loader instances — underscore systemic risks as AI integrations demand broader data access. Recommended mitigations include IP whitelisting, DPoP or mTLS, and tighter vendor governance.

🪲 Researchers at Koi Security have uncovered GlassWorm, a sophisticated self-propagating malware campaign affecting extensions in the OpenVSX and Microsoft VS Code marketplaces. The worm hides executable payloads using Unicode variation selectors, harvests NPM, GitHub and Git credentials, drains 49 cryptocurrency wallets, and deploys SOCKS proxies and hidden VNC servers on developer machines. CISOs are urged to treat this as an immediate incident: inventory VS Code usage, monitor for anomalous outbound connections and long-lived SOCKS/VNC processes, rotate exposed credentials, and block untrusted extension registries.

🔒 A European telecommunications organization was targeted in the first week of July 2025, according to Darktrace, with a threat actor linked to the China-associated group Salt Typhoon gaining initial access via a vulnerable Citrix NetScaler Gateway. The intruders pivoted to Citrix VDA hosts in an MCS subnet and used SoftEther VPN to mask their origin. They deployed Snappybee (aka Deed RAT) via DLL side-loading alongside legitimate antivirus executables; the backdoor called home to aar.gandhibludtric[.]com. Darktrace says the activity was detected and remediated before significant escalation.

🔒 Muji has temporarily taken its Japan online store offline after a ransomware attack disrupted logistics systems at its delivery partner, Askul. The outage affects browsing, purchases, order histories in the Muji app, and some web content; Muji is investigating which shipments and pre-attack orders were impacted and will notify affected customers by email. Askul confirmed a ransomware infection suspended orders, shipping, and several customer services while it investigates potential data exposure; international Muji stores remain operational.

🛡️ A sophisticated supply-chain campaign called GlassWorm is propagating through OpenVSX and Microsoft VS Code extensions and is estimated to have about 35,800 active installs. The malware conceals malicious scripts using invisible Unicode characters, then steals developer credentials and cryptocurrency wallet data while deploying SOCKS proxies and hidden VNC clients for covert access. Operators rely on the Solana blockchain for resilient C2, with Google Calendar and direct-IP fallbacks.

🔐 British officials briefly considered physically destroying a government data hub after uncovering a decade-long intrusion attributed to China-aligned actors. The breach reportedly exposed official-sensitive and secret material on government servers, though no top secret data was taken. Rather than demolish the facility, the government implemented alternative protections and commissioned a classified review. Cybersecurity experts say the episode underscores the critical need to secure supply chains and hunt long-term APT presence.

🛡️ Google Threat Intelligence Group (GTIG) reports that North Korean-linked UNC5342 is using a method called EtherHiding to deliver malware and facilitate cryptocurrency theft by embedding encrypted payloads in smart contracts on Ethereum and BNB Smart Chain. The technique turns immutable contracts into resilient, hard-to-takedown command-and-control infrastructure. Initial lures include fake recruiter messages, poisoned npm packages and malicious GitHub repositories; a JavaScript downloader named JADESNOW fetches and decrypts subsequent backdoors such as INVISIBLEFERRET.

🔐 Cisco Talos reports that a North Korean-linked threat cluster has blended features of its BeaverTail and OtterCookie JavaScript malware families, with recent OtterCookie variants adding keylogging, screenshot capture, and clipboard monitoring. The intrusion chain observed involved a trojanized Node.js application called Chessfi and a malicious npm dependency published on August 20, 2025 that executed postinstall hooks to launch multi-stage payloads. Talos tied the activity to the Contagious Interview recruitment scam and highlighted continued modularization and abuse of legitimate open-source packages and public Git hosting to distribute malicious code.

🔍 Hidden blocks of links embedded on corporate websites can quietly erode search rankings and damage reputation by pointing to dubious domains such as pornography or gambling. Invisible to users but parsed by search engines and security tools, these links divert link equity and often trigger algorithmic penalties. Attackers inject them via compromised admin credentials, vulnerable CMS components, infected templates, or breached hosting. Regular updates, strict access controls, routine audits, backups, and mandatory 2FA help prevent and limit impact.

🔒 On Oct. 15, 2025, F5 disclosed a nation-state compromise that exfiltrated source code and undisclosed vulnerability information from the BIG-IP product development and engineering knowledge platforms. F5 reports no evidence of modification to its software supply chain or access to CRM, financial, support case management, iHealth, NGINX or distributed cloud products. Unit 42 warns the theft could accelerate exploit development and recommends immediate patching, hardening, and targeted threat hunting for anomalous admin activity and configuration changes.

🔐 Google Threat Intelligence has linked a campaign to UNC5342, a cluster tied to North Korea, that now uses EtherHiding to distribute malware via smart contracts on public blockchains such as BNB Smart Chain and Ethereum. The attackers lure developers through LinkedIn recruitment ruses, move conversations to Telegram or Discord, and deliver npm-package downloaders that chain into BeaverTail, JADESNOW, and the Python backdoor InvisibleFerret. By embedding payloads in on-chain contracts, the group turns blockchains into tamper-resistant dead-drops that are hard to takedown and easy to update, enabling sustained cryptocurrency theft and long-term espionage.

🔐 Since late 2023, Mandiant and the Google Threat Intelligence Group tracked UNC5142, a financially motivated cluster that compromises vulnerable WordPress sites to distribute information stealers. The actor's CLEARSHORT JavaScript loader uses Web3 to query smart contracts on the BNB Smart Chain that store ABIs, encrypted landing pages, AES keys, and payload pointers. By employing a three-contract Router-Logic-Storage design and abusing legitimate hosting (Cloudflare Pages, GitHub, MediaFire), operators can rotate lures and update payload references on-chain without changing injected scripts, enabling resilient, low-cost campaigns that GTIG found on ~14,000 injected pages by June 2025 and which showed no on-chain updates after July 23, 2025.

🧩 GTIG reports that DPRK-linked UNC5342 has adopted EtherHiding, using smart contracts on public blockchains to store and deliver malicious JavaScript payloads. The actor leverages social engineering—fake recruiter lures and technical interviews—to deploy the JADESNOW downloader, which fetches and decrypts on-chain payloads and stages the Python backdoor INVISIBLEFERRET. Google recommends enterprise controls and Chrome management policies to disrupt this resilient, decentralized C2 method.

⚠️ F5 has confirmed a nation-state actor maintained persistent access to its development systems, including the BIG-IP product development environment and engineering knowledge management platforms, with discovery in August and customer notification on October 15. The breach included stolen files containing BIG-IP source code and information on undisclosed vulnerabilities. While F5 reports no known active exploitation, it and CISA have urged immediate patching and mitigations, and the US government delayed public disclosure in September after a Justice Department order.

🔒 F5 Networks acknowledged that a highly sophisticated threat actor exfiltrated portions of BIG-IP source code, information about undisclosed vulnerabilities, and configuration data for a small percentage of customers. The company says there is no evidence of modification to its build pipelines or active exploitation of undisclosed critical vulnerabilities. F5 has released security updates for BIG-IP, F5OS, BIG-IP Next for Kubernetes, BIG‑IQ, and APM clients and urges customers to apply them immediately. CISA has directed federal agencies to assess internet-exposed BIG-IP devices, and F5 will provide eligible customers a free subscription to CrowdStrike Falcon EDR.

🔎 Symantec attributes a five‑month intrusion (Jan–May 2025) against a Russian IT service provider to a China‑linked group tracked as Jewelbug, connecting it with clusters CL‑STA‑0049/REF7707 and Earth Alux. Attackers accessed code repositories and build systems and exfiltrated data to Yandex Cloud, creating supply‑chain concerns. The campaign used a renamed cdb.exe to run shellcode, bypass allowlisting, dump credentials, establish persistence, and clear event logs. Symantec also ties Jewelbug to recent intrusions in South America, South Asia, and Taiwan that leverage cloud services, DLL side‑loading, ShadowPad, BYOVD techniques, and novel OneDrive/Graph API C2.

🔒 F5 disclosed that unidentified threat actors accessed its systems and exfiltrated files including portions of BIG-IP source code and documentation on undisclosed product vulnerabilities. The company attributed the intrusion to a highly sophisticated nation-state threat actor, reported detection on August 9, 2025, and said it has contained the activity. F5 engaged Google Mandiant and CrowdStrike, rotated credentials, strengthened controls, and advised customers to apply updates to BIG-IP, F5OS, BIG-IQ, and APM clients.

🔒 Wiz researchers found that publishers of over 100 Visual Studio Code extensions leaked personal access tokens and other secrets that could allow attackers to push malicious extension updates across large install bases. The team validated more than 550 secrets across 500+ extensions spanning 67 types, including AI provider keys, cloud credentials, database and payment secrets. Over 100 extensions exposed Marketplace PATs (≈85,000 installs) and ~30 exposed Open VSX tokens (≈100,000 installs); many flagged packages were themes and hard-coded secrets in .vsix files were often discoverable. Microsoft revoked leaked tokens after disclosure and is adding secret-scanning; users and organizations were advised to limit extensions, vet packages, maintain inventories, and consider centralized allowlists.

🔒 F5 disclosed that nation-state attackers breached its systems and exfiltrated portions of BIG-IP source code and information about undisclosed vulnerabilities after gaining persistent access to product development and engineering knowledge platforms. The company says it first detected the intrusion on August 9, 2025, and has found no evidence the stolen data has been exploited or publicly disclosed. F5 reports that its software supply chain was not compromised and no suspicious code modifications were observed, while it continues identifying customers whose configuration or implementation details may have been taken.

⚠️ Koi Security disclosed a coordinated campaign by a group dubbed TigerJack that published malicious extensions to the Visual Studio Code Marketplace and the OpenVSX registry to exfiltrate source code, deploy cryptominers, and maintain remote access. Two popular packages — C++ Payground and HTTP Format — accumulated over 17,000 downloads before removal from Microsoft's store, yet variants remain active on OpenVSX. Researchers warn that the most advanced builds fetch and execute remote JavaScript, allowing attackers to push new payloads without republishing and evading static scanners.
