North Korean-linked threat actor "Contagious Interview" has distributed over 1,700 malicious packages across npm, PyPI, Go, Rust, and Packagist ecosystems since January 2025 Malicious code is hidden within legitimate-looking functions and only executes at runtime, not during installation, making detection harder Packages function as malware loaders delivering second-stage payloads with infostealer, RAT, and post-compromise capabilities including keylogging and remote access C

Key Findings 36 malicious npm packages masquerading as Strapi CMS plugins uploaded by four sock puppet accounts over 13 hours Eight distinct payload variants reveal real-time attack development against a specific target Exploitation chain includes Redis RCE, PostgreSQL database theft, Docker container escape, and persistent C2 implants Packages target cryptocurrency platform infrastructure with hardcoded database credentials and wallet-specific data harvesting Postinstall scr

Key Findings North Korean threat group UNC1069 is conducting coordinated social engineering campaigns against open source maintainers, particularly those managing Node.js and npm packages Attackers use fake LinkedIn profiles, Slack messages, and spoofed video conferencing platforms to build rapport over weeks before delivering remote access trojans Goal is to compromise maintainer credentials and gain write access to popular packages, allowing injection of malicious code into

Key Findings Anthropic leaked approximately 512,000 lines of Claude Code source code through a misconfigured npm source map file on March 31, 2026 The leak was discovered within hours by an intern at Solayer Labs and rapidly mirrored across the internet Claude Code generates $2.5 billion annually, representing a significant portion of Anthropic's $19 billion total revenue The exposed code reveals proprietary solutions including a three-layer memory system designed to prevent

Key Findings Anthropic confirmed Claude Code source code was accidentally exposed via npm package version 2.1.88 due to human error in packaging, not a security breach Nearly 2,000 TypeScript files and over 512,000 lines of code were leaked through a source map file and quickly spread across public repositories The leaked codebase revealed advanced features including KAIROS autonomous daemon mode, self-healing memory architecture, Undercover Mode for stealth contributions, an

Key Findings Seven malicious npm packages tracked as "Ghost campaign" designed to steal cryptocurrency wallets and credentials Packages use sophisticated social engineering tactics including fake installation logs and sudo password phishing Attack chain culminates in remote access trojan capable of harvesting sensitive data and awaiting attacker commands Activity shares overlap with GhostClaw campaign, suggesting possible connection between threat actors Packages published un

Key Findings Campaign named FAUX#ELEVATE targets French-speaking corporate environments using fake resume documents delivered via phishing emails Heavily obfuscated VBScript files contain only 266 lines of executable code out of 224,471 total lines, with the rest being junk comments to evade detection Attack completes full infection chain in approximately 25 seconds, from initial execution through credential exfiltration Malware exclusively targets domain-joined enterprise ma

Key Findings * TeamPCP cybercriminal group suspected behind supply chain attack * 47 npm packages compromised across multiple scopes * Self-propagating CanisterWorm uses ICP blockchain canister as command-and-control infrastructure * Attack leverages npm package postinstall hooks to execute malware * Worm can automatically spread using stolen npm authentication tokens * Decentralized C2 infrastructure makes takedown efforts difficult Background The supply chain attack targets

Background The cybersecurity researchers at Veracode have discovered a new type of supply chain attack targeting the NPM ecosystem. The attack involves hiding a dangerous Pulsar Remote Access Trojan (RAT) inside seemingly innocuous PNG image files. Key Findings Hackers used a typosquatting technique to create a malicious NPM package named "buildrunner-dev" that closely resembles a legitimate tool called "buildrunner". Once installed, the package downloads a heavily obfuscated

Key Findings Cybersecurity researchers have discovered a fresh set of malicious packages across npm and the Python Package Index (PyPI) repository linked to a fake recruitment-themed campaign orchestrated by the North Korea-linked Lazarus Group. The coordinated campaign has been codenamed "graphalgo" in reference to the first package published in the npm registry, and it's assessed to be active since May 2025. The campaign includes a well-orchestrated story around a company i

Key Findings Security firm Koi discovered a set of vulnerabilities collectively tracked as "PackageGate" affecting major JavaScript package managers like NPM, PNPM, VLT, and Bun. These flaws could let attackers bypass supply chain protections and run malicious code hidden inside compromised dependencies. The safeguards widely promoted after the Shai-Hulud attack, such as disabling lifecycle scripts and relying on lockfiles, do not fully hold against these new "PackageGate" vu

Key Findings Researchers from Zscaler ThreatLabz discovered three malicious npm packages that deliver a new Remote Access Trojan (RAT) called NodeCordRAT. The packages - bitcoin-main-lib, bitcoin-lib-js, and bip40 - were designed to mimic legitimate tools from the bitcoinjs project, tricking developers into installing them. NodeCordRAT uses Discord as a command-and-control (C2) channel, blending its malicious traffic with legitimate user activity to evade detection. The malwa

Key Findings An NPM package named 'Lotusbail' with over 56,000 downloads has been stealing WhatsApp credentials and data The package is a fork of the legitimate 'Baileys' WhatsApp Web API library, making it hard to detect It intercepts and exfiltrates user credentials, messages, contacts, and media, encrypting the data with custom RSA before sending it to the attacker The malware also hijacks the WhatsApp device pairing process, secretly linking the attacker's device to the v

Key Findings: A malicious npm package named "lotusbail" has been discovered that poses as a functional WhatsApp API, but actually steals users' messages, contacts, and login tokens. The package has been downloaded over 56,000 times since it was first uploaded in May 2025. The package is designed to capture authentication tokens, session keys, message history, contact lists, media files, and documents, and transmit the stolen data to an attacker-controlled server. The package

Key Findings North Korea-linked actors behind the Contagious Interview campaign have uploaded 197 new malicious npm packages to distribute a new version of the OtterCookie malware. The Contagious Interview campaign, active since November 2023, targets software developers on Windows, Linux, and macOS, with a focus on those working in crypto and Web3. Attackers pose as recruiters on platforms like LinkedIn and use social engineering tactics, including fake job interviews and tr

Key Findings North Korean threat actors behind the Contagious Interview campaign have flooded the npm registry with 197 more malicious packages since last month These packages have been downloaded over 31,000 times and are designed to deliver a variant of OtterCookie malware The malware attempts to evade sandboxes and virtual machines, profiles the machine, and establishes a command-and-control (C2) channel to provide the attackers with remote shell access and capabilities to

Key Findings Seven npm packages published by a threat actor using the alias "dino_reborn" were found to be part of a highly coordinated malware campaign The packages use Adspect-powered cloaking, anti-analysis JavaScript, and fake CAPTCHA interfaces to funnel unsuspecting victims toward malicious payloads while hiding their activity from security researchers The threat actor built an entire fake website to serve security researchers while real victims are redirected through a
