GitHub Actions workflows abused in 'GhostAction' campaign

🔒 GitGuardian disclosed a campaign called "GhostAction" that tampers with GitHub Actions workflows to harvest and exfiltrate secrets to attacker-controlled domains. Attackers modified workflow files to enumerate repository secrets, hard-code them into malicious workflows, and forward credentials such as container registry and cloud provider keys. The researchers say 3,325 secrets from 327 users across 817 repositories were stolen, and they published IoCs while urging maintainers to review workflows, rotate exposed credentials, and tighten Actions controls.

Open Source Community Stops Large npm Supply-Chain Attack

🔒 A rapid open source response contained a supply-chain compromise after maintainer Josh Junon (known as 'qix') reported his npm account was hijacked on September 8. Malicious versions of widely used packages including chalk, strip-ansi and color-convert were published embedding an crypto-clipper that swaps wallet addresses and hijacks transactions. The community and npm removed tainted releases within hours, limiting financial impact and exposure.

Massive npm Supply Chain Attack Compromises 18 Packages

🔓 Security firm Aikido uncovered a coordinated supply chain attack that injected obfuscated, browser-based malware into 18 popular npm packages — including chalk, debug, and ansi-styles — collectively receiving two billion weekly downloads. The malicious updates, pushed beginning September 8, intercept and manipulate web3 and crypto interactions in the browser to silently rewrite payment destinations and approvals. The campaign originated from a phishing operation that abused a typosquatted domain (npmjs.help) to compromise maintainer accounts, and although the attacker demonstrated web3 knowledge, tracked losses were modest (~$970). Researchers warn enterprise defenses are largely blind to this API-level interceptor and call for stronger attestation and signed publication workflows.

Popular npm packages trojanized to mine cryptocurrency

⚠️ Several widely used npm packages were trojanized after attackers phished maintainers, injecting obfuscated JavaScript that turns affected web applications into cryptodrainers. The malicious code executes in visitors' browsers, intercepting network traffic and API requests to rewrite cryptocurrency wallet addresses for Ethereum, Bitcoin, Solana, Litecoin, Bitcoin Cash and Tron and redirect funds to attacker-controlled wallets. npm removed infected packages about three hours after the attack began, but total downloads during that window remain unknown. Developers are advised to audit dependencies, pin safe versions with overrides in package.json, and use anti-phishing protections.

Phished Maintainer Leads to Compromise of 20 npm Packages

⚠️ A maintainer of widely used npm packages was phished, allowing attackers to publish malicious updates to 20 modules that together exceed two billion weekly downloads. Researchers from Aikido Security and Socket found the injected payload hooks browser APIs (window.fetch, XMLHttpRequest, window.ethereum.request) to intercept and rewrite cryptocurrency transactions. The malware substitutes recipient addresses by computing Levenshtein distance to closely match intended wallets, putting end users and developers who connect wallets at risk. The incident highlights the persistent supply-chain threat to package ecosystems.

18 Popular JavaScript Packages Hijacked to Steal Crypto

🔐 Akido researchers found that at least 18 widely used JavaScript packages on NPM were briefly modified after a maintainer was phished, impacting libraries downloaded collectively more than two billion times weekly. The injected code acted as a stealthy browser interceptor, capturing and rewriting cryptocurrency wallet interactions and payment destinations to attacker-controlled accounts. The changes were rapidly removed, but experts warn the same vector could deliver far more disruptive supply-chain malware if not addressed. Security specialists urge mandatory phish-resistant 2FA and stronger commit attestation for high-impact packages.

GhostAction GitHub Supply Chain Attack Exposes 3,325 Secrets

🚨 A GitHub supply chain campaign dubbed GhostAction has exposed 3,325 secrets across multiple package ecosystems and repositories. GitGuardian says attackers abused compromised maintainer accounts to insert malicious GitHub Actions workflows that trigger on push or manual dispatch, read repository secrets, and exfiltrate them via HTTP POST to an external domain. Compromised credentials include PyPI, npm, DockerHub, Cloudflare, AWS keys and database credentials; vendors were notified and many repositories reverted the changes.

Attackers Inject Malware into Popular npm Packages

🚨 Attackers phished and hijacked a package maintainer's account via a fake support domain, then updated index.js files in multiple npm packages to inject a browser-based interceptor. The malicious code targets web clients, monitoring Ethereum, Bitcoin, Solana, Tron, Litecoin and Bitcoin Cash transactions and replacing wallet destinations to redirect funds. Affected packages collectively account for over 2.6 billion weekly downloads, making this a substantial supply-chain compromise. Investigation and remediation are ongoing.

GhostAction Campaign Steals 3,325 Secrets via GitHub Actions

🔍GitGuardian disclosed a GitHub Actions supply chain campaign named GhostAction that exfiltrated 3,325 secrets from 327 users across 817 repositories before being contained on September 5. Attackers injected malicious workflow files to harvest CI/CD tokens (including PYPI_API_TOKEN) and sent them via HTTP POST to an actor-controlled endpoint. GitGuardian coordinated with maintainers and registries to revert commits, set impacted packages to read-only, and notify vendors.

Malicious npm Packages Impersonate Flashbots, Steal Keys

🔑 Researchers found four malicious npm packages impersonating Flashbots and common cryptographic utilities to harvest Ethereum wallet credentials. Uploaded by user "flashbotts" between September 2023 and August 19, 2025, the libraries exfiltrate private keys and mnemonic seed phrases to a Telegram bot and transmit environment data via Mailtrap SMTP. One package also redirects unsigned transactions to an attacker-controlled wallet.

Malicious npm Packages Use Ethereum to Deliver Malware

⚠️ ReversingLabs researchers uncovered a supply chain campaign that used Ethereum smart contracts to conceal URLs for malware delivered via rogue GitHub repositories and npm packages. The packages colortoolsv2 and mimelib2 were intentionally minimal and designed to be pulled as dependencies from fraudulent repositories posing as cryptocurrency trading bots. Attackers inflated commit histories with sockpuppet accounts and automated pushes to appear legitimate, then used on-chain storage to hide secondary payload locations and evade URL-scanning defenses.

Malicious npm Packages Use Ethereum Smart Contracts

🔒 Cybersecurity researchers discovered two malicious npm packages that use Ethereum smart contracts to hide commands and deliver downloader malware to compromised systems. The packages — colortoolsv2 (7 downloads) and mimelib2 (1 download) — were uploaded in July 2025 and removed from the registry. The campaign leveraged a network of GitHub repositories posing as crypto trading tools and is linked to a distribution-as-service operation called Stargazers Ghost Network. Developers are urged to scrutinize packages and maintainers beyond surface metrics before adopting libraries.

Malicious npm Packages Use Ethereum Smart Contracts

🛡️A new campaign used malicious npm packages to hide command-and-control URLs inside Ethereum smart contracts, evading typical static detection. ReversingLabs researcher Karlo Zanki uncovered packages colortoolsv2 and mimelib2 that delivered second-stage payloads via blockchain-held URLs. The threat also included fake GitHub projects, such as solana-trading-bot-v2, built to appear legitimate. Developers are urged to vet dependencies and maintainers beyond superficial metrics.

Malicious npm Package Mimics Nodemailer, Targets Wallets

🛡️ Researchers found a malicious npm package named nodejs-smtp that impersonated the nodemailer mailer to avoid detection and entice installs. On import the module uses Electron tooling to unpack an app.asar, replace a vendor bundle with a payload, repackage the application, and erase traces to inject a clipper into Windows desktop wallets. The backdoor redirects BTC, ETH, USDT, XRP and SOL transactions to attacker-controlled addresses while retaining legitimate mailer functionality as a cover.

Supply-Chain Attack on npm Nx Steals Developer Credentials

🔒 A sophisticated supply-chain attack targeted the widely used Nx build-system packages on the npm registry, exposing developer credentials and sensitive files. According to a report from Wiz, attackers published malicious Nx versions on August 26, 2025 that harvested GitHub and npm tokens, SSH keys, environment variables and cryptocurrency wallets. The campaign uniquely abused installed AI CLI tools (for example, Claude and Gemini) by passing dangerous permission flags to exfiltrate file-system contents and perform reconnaissance, then uploaded roughly 20,000 files to attacker-controlled public repositories. Organizations should remove affected package versions, rotate exposed credentials and inspect developer workstations and CI/CD pipelines for persistence.

Nx Build Supply-Chain Attack: Trojanized Packages Detected

🔐 The Nx package ecosystem was trojanized via a malicious post-install script, telemetry.js, which exfiltrated developer secrets from macOS and *nix environments. Stolen items included npm and GitHub tokens, SSH keys, crypto wallets, API keys and .env contents, uploaded to public GitHub repositories. Immediate actions include auditing Nx package versions, removing affected node_modules, rotating all potentially exposed secrets and monitoring repositories and Actions for misuse.

Malicious Nx npm Packages in 's1ngularity' Supply Chain

🔒 The maintainers of nx warned of a supply-chain compromise that allowed attackers to publish malicious versions of the npm package and several supporting plugins that gathered credentials. Rogue postinstall scripts scanned file systems, harvested GitHub, cloud and AI credentials, and exfiltrated them as Base64 to public GitHub repositories named 's1ngularity-repository' under victim accounts. Security firms reported 2,349 distinct secrets leaked; maintainers rotated tokens, removed the malicious versions, and urged immediate credential rotation and system cleanup.

OSS Rebuild: Reproducible Builds to Harden Open Source

🔐 Google’s Open Source Security Team today announced OSS Rebuild, a new project to reproduce upstream artifacts and supply SLSA-grade provenance for popular package ecosystems. The service automates declarative build definitions and reproducible builds for PyPI, npm, and Crates.io, generating attestations that meet SLSA Build Level 3 requirements without requiring publisher changes. Security teams can use the project to verify published artifacts, detect unexpected embedded source or build-time compromises, and integrate the resulting provenance into vulnerability response workflows. The project is available as a hosted data set and as open-source tooling and infrastructure for organizations to run their own rebuild pipelines.
