⚠️ CISA has added a critical vulnerability (CVE-2025-59374, CVSS 9.3) in ASUS Live Update to its Known Exploited Vulnerabilities catalog after identifying evidence of active exploitation tied to a supply-chain compromise. The flaw stems from trojanized installer builds distributed during the 2018 Operation ShadowHammer campaign that could make targeted devices perform unintended actions. ASUS previously remediated the issue in v3.6.8, but the vendor has since declared the client end-of-support; federal agencies are urged to discontinue use by January 7, 2026.

🚨 Koi Security uncovered the GhostPoster campaign that hid malicious JavaScript inside PNG logo files used by 17 Firefox add‑ons, collectively downloaded more than 50,000 times. The steganographic loader fetches secondary payloads from attacker-controlled servers only intermittently and uses long delays to avoid detection. Affected extensions — advertised as VPNs, ad blockers, translators, and utilities — have been removed from distribution.

🕵️ Koi Security identified the GhostPoster campaign that hides JavaScript inside PNG logo images of malicious Firefox extensions, impacting more than 50,000 downloads. The dormant loader waits 48 hours, contacts hardcoded attacker domains and only fetches its payload about 10% of the time to evade detection. The decoded payload provides persistent, high-privilege access and enables affiliate hijacks, analytics injection, header stripping, CAPTCHA bypass and ad/click fraud. Users of flagged extensions should remove them and consider resetting critical account passwords.

🔒 A malicious NuGet package named "Tracer.Fody.NLog" was published on February 26, 2020 and impersonates the legitimate Tracer.Fody maintainer to deliver a cryptocurrency wallet stealer. The embedded Tracer.Fody.dll scans the default Stratis wallet directory (%APPDATA%\StratisNode\stratis\StratisMain), reads *.wallet.json files and in-memory passwords, and exfiltrates data to 176.113.82[.]163. Socket researcher Kirill Boychenko highlighted multiple evasion tactics — a typosquatted publisher name, Cyrillic lookalikes in code, and a hidden routine inside a helper method that runs during normal execution while suppressing exceptions.

🔒AWS Security details its incident response to multiple high-scale npm supply chain campaigns, including the compromised Nx package, the Shai-Hulud worm, and a token-farming operation detected by Amazon Inspector. Teams enacted rapid containment (repository blocklisting, OpenSSF registration), performed deep analysis using AI-assisted detonation in sandboxes, and automated disclosures to protect customers. The effort produced improved behavioral detections, GenAI prompt guardrails for Amazon Q, and strengthened collaboration with the security community to reduce future exposure.

🔒 The UK National Cyber Security Centre (NCSC) has published a practical playbook urging businesses to embed Cyber Essentials across supply chains and to use its new Supplier Check tool to verify supplier certification (CE or CE Plus). It highlights that firms with turnover under £20m qualify for free cyber‑liability insurance and incident response support when certified. The seven-step guidance covers risk mapping, defining security profiles, setting and enforcing minimum security requirements, incentivizing CE, embedding adoption into procurement and monitoring uptake.

🔍 ReversingLabs discovered a stealthy campaign of 19 malicious VSCode Marketplace extensions that bundled dependencies to run a trojan hidden inside a faux PNG file. The packages included modified 'path-is-absolute' or '@actions/io' modules which auto-execute code via an added class in index.js, decoding an obfuscated JavaScript dropper stored in a file named 'lock'. A fake 'banner.png' archive contained two payloads — a living-off-the-land binary 'cmstp.exe' and a Rust-based trojan — and Microsoft removed the extensions after being notified.

🔍 ReversingLabs uncovered a campaign that embedded malware in 19 Visual Studio Code extensions by tampering with bundled dependencies. Attackers replaced the widely used npm package path-is-absolute to execute a JavaScript dropper from a file named "lock" and hid two binaries inside an archive disguised as banner.png. The payloads were launched via cmstp.exe, including a process-terminating component and a Rust-based Trojan; Microsoft has been notified.

🔔 This week's ThreatsDay Bulletin highlights a packed week of cross-cutting threats: a Mirai variant dubbed Broadside exploiting TBK DVRs (CVE-2024-3721), widespread exploitation of React2Shell (CVE-2025-55182), and the leak of a ValleyRAT builder that includes a signed kernel-mode rootkit. Law enforcement actions ranged from Europol's 193 arrests in a VaaS crackdown to multiple national detentions, while Apple and Google issued broad spyware alerts. Researchers flagged >10,000 Docker Hub images leaking secrets and 19 malicious VS Code extensions that used a PNG disguise to deliver trojans, underscoring persistent supply-chain and user-facing risks.

⚠️ Researchers observed threat actors distributing the StealC V2 infostealer hidden inside free .blend files on marketplaces like CGTrader. When Blender’s Auto Run Python Scripts setting is enabled, opening these models executes embedded Python that fetches a loader via Cloudflare Workers and runs a PowerShell chain to deploy payloads. The campaign exfiltrated browser and wallet data and abused a UAC bypass. Disable autorun and restrict unvetted tools.

🛡️ The Shai-Hulud 2.0 campaign is a widescale npm supply-chain compromise that injects malicious preinstall scripts to execute a bundled Bun runtime and harvest cloud credentials. Microsoft Defender observed attackers installing GitHub Actions runners named SHA1HULUD, using TruffleHog to locate secrets, and exfiltrating stolen credentials to public repositories. The guidance outlines detections, hunting queries, and prioritized mitigations for developers, maintainers, and cloud defenders.

🛡️ Researchers from Koi Security have uncovered two malicious Visual Studio Code extensions, Bitcoin Black and Codo AI, that delivered a DLL-based infostealer via a disguised Lightshot executable. The campaign used social engineering and evolving technical methods—initially complex PowerShell and passworded ZIPs, later streamlined to hidden batch scripts—to harvest screenshots, clipboard data, Wi‑Fi credentials and browser sessions. One extension posed as a theme while the other offered legitimate AI coding features, helping both evade suspicion on the VS Code Marketplace.

🔒 Security researchers uncovered malicious extensions on the Microsoft Visual Studio Code Marketplace that delivered stealer malware while posing as a dark theme and an AI assistant. Koi Security reported the extensions downloaded additional payloads, captured screenshots, and siphoned emails, Slack messages, Wi‑Fi passwords, clipboard contents and browser sessions to attacker servers. Microsoft removed the packages in early December 2025 after investigators linked them to a publisher using multiple similarly named packages.

🛡️ Two malicious Visual Studio Code extensions on Microsoft's Marketplace, Bitcoin Black and Codo AI, were found delivering an information-stealing payload that can capture screenshots, harvest credentials and crypto wallets, and hijack browser sessions. Published under the developer name 'BigBlack', Codo AI remained live with under 30 downloads at the time of reporting while Bitcoin Black showed a single install. Researchers at Koi Security observed that Bitcoin Black uses a wildcard activation and executes PowerShell or a hidden batch script to download a DLL and executable that leverage DLL hijacking to run the infostealer as 'runtime.exe'.

🔒This week's ThreatsDay roundup highlights a string of high-impact incidents, from a $9 million DeFi drain and an npm-based self-replicating worm to airport Wi‑Fi evil‑twin attacks and mass camera compromises. Researchers and vendors including Fortinet, Microsoft, and TruffleHog disclosed evolving malware techniques, supply-chain abuse, and widespread credential exposure. Practical protections include minimizing long-lived secrets, enforcing CI/CD safeguards, updating detection for eBPF-based threats, and applying MFA and phishing-resistant controls.

⚠️ Researchers identified a malicious Rust crate, evm-units, on crates.io that targeted developer machines running Windows, macOS, and Linux by posing as an Ethereum Virtual Machine helper. Uploaded in mid‑April 2025 and downloaded thousands of times, the package fetched OS-specific payloads from download.videotalks[.]xyz, wrote them to temporary directories, and executed them silently. A related package, uniswap-utils, included evm-units as a dependency, widening exposure; both packages have been removed and indicators released to help defenders.

🔒 Wiz researchers say the second Shai-Hulud NPM malware wave infected hundreds of packages and exposed roughly 400,000 raw secrets across some 30,000 GitHub repositories. Although TruffleHog verified about 10,000 secrets, Wiz found over 60% of leaked NPM tokens still valid as of Dec 1, leaving active credentials at risk. The payload propagated via the preinstall event (node setup_bun.js), affected over 800 package versions, and included a conditional destructive home-directory wipe. A small number of packages — notably @postman/tunnel-agent@0.6.7 and @asyncapi/specs@6.8.3 — represented the bulk of infections, indicating targeted mitigation could have sharply reduced impact.

🔍 The GlassWorm supply-chain campaign has resurfaced with 24 malicious extensions distributed across the Microsoft Visual Studio Marketplace and Open VSX, impersonating popular developer tools such as Flutter, React and Tailwind. Researchers say attackers inflated download counts and slipped malicious updates after initial approval to evade filters. Analysis found Rust-based implants that load platform-specific libraries (os.node and darwin.node) to fetch Solana-based C2 details and download encrypted JavaScript payloads, while a Google Calendar fallback is also used. Developers and repository maintainers are urged to audit installed extensions and review update histories.

⚠️ Security researchers disclosed that an npm package, eslint-plugin-unicorn-ts-2, embeds a deceptive prompt aimed at biasing AI-driven security scanners and also contains a post-install hook that exfiltrates environment variables. Uploaded in February 2024 by user "hamburgerisland", the trojanized library has been downloaded 18,988 times and remains available; the exfiltration was introduced in v1.1.3 and persists in v1.2.1. Analysts warn this blends familiar supply-chain abuse with deliberate attempts to evade LLM-based analysis.

🐛 The Glassworm campaign has resurfaced in a third wave, with 24 new malicious VS Code-compatible extensions appearing on both the Microsoft Visual Studio Marketplace and OpenVSX. Once installed, these extensions push updates that deploy Rust-based implants, use invisible Unicode to evade review, exfiltrate GitHub, npm, and OpenVSX credentials and cryptocurrency wallet data, and deploy a SOCKS proxy and an HVNC client for stealthy remote access. Researchers say attackers inflate download counts to blend with legitimate projects and manipulate search results; both vendors have been contacted about continued bypasses.
