Open Source Software Developers Remain Target for North Korean Hackers in Ongoing Malware Campaign, with Security Experts Estimating Up to 36,000 Victims Compromised

In recent times, the cybersecurity landscape has been altered by a surge in malware attacks targeting open source ecosystems, such as NPM and Python Package Index (PyPI). These attacks, believed to be orchestrated by the Lazarus Group, a North Korean hacking organization, have the potential to affect as many as 36,000 victims.

The Lazarus Group, known for their involvement in the 2017 WannaCry ransomware incident and the 2014 Sony Pictures hack, among others, has shifted its focus from disruption to long-term infiltration. They are using tailored malware, modular payloads, and infrastructure evasion techniques to embed malicious code into open-source package registries.

Security firm Sonatype has blocked 234 unique malware packages linked to the Lazarus Group, highlighting the urgency of the situation. These attacks are designed to steal secrets, profile hosts, and open persistent backdoors into critical infrastructure.

To protect your open source ecosystems, developers are advised to adopt a multi-layered defense strategy. Here are some key measures:

  1. Use Multi-Factor Authentication (MFA) and Strong Auth Methods: Enforce MFA on maintainer accounts for package registries like NPM and consider hardware security keys or biometric passkeys instead of just authenticator apps to mitigate phishing, as phishing attacks on maintainers often trigger supply chain compromises.
  2. Pin Exact Package Versions and Audit Dependencies Regularly: Always pin dependencies to specific versions in package-lock.json (NPM) or equivalent, and regularly audit dependency trees using tools like or equivalent PyPI vulnerability scanners to detect unexpected or malicious code introductions.
  3. Monitor and Automate Vulnerability Scanning: Subscribe to security advisories (from NPM, PyPI, Snyk, or WhiteSource) to stay updated on known vulnerabilities. Integrate automated vulnerability scanning tools (e.g., Snyk, JFrog) into CI/CD pipelines to catch issues proactively.
  4. Review Maintainer Activity and Package Ownership Changes: Check recent commits, GitHub activity, and ownership changes on packages before updating dependencies to detect suspicious behavior or sudden changes that may signal compromise.
  5. Adopt Private Registries or Mirrors: Use private package registries or mirrors (e.g., Verdaccio for NPM) to control which package versions are allowed in production environments, reducing exposure to compromised public packages.
  6. Manage Access Restrictions and Permissions: Limit publishing permissions to trusted maintainers only and apply access control tools to restrict who can install or publish packages. Tools like Verdaccio provide fine-grained control over access and publishing rights.
  7. Swift Response to Security Incidents: If compromise is detected, maintainers should quickly revoke compromised tokens or credentials, deprecate affected package versions, and publish clean updates to minimize impact.

While specific tactics to detect North Korean hacker activity may not be public, these general best practices help defend open source ecosystems from sophisticated supply chain malware attacks, including those potentially originating from state-sponsored actors.

In addition, enforcing stricter governance policies to avoid installing dodgy packages with unclear provenance or low download histories without extra checks is recommended. Intelligence sharing is beneficial for businesses, as it allows for the rapid dissemination of information about new threats and best practices for mitigation.

As nation-state actors continue to shift the battlefield into everyday development workflows by embedding malware into developer tools and using software pipelines as delivery channels, it is crucial for developers to stay vigilant and proactive in their security measures. Regularly scanning for indicators of compromise is part of a recommended multi-layered defense strategy.

  1. The surge in malware attacks targeting open source ecosystems, such as NPM and PyPI, by the Lazarus Group, a North Korean hacking organization, is a reminder of the importance of employing robust cybersecurity measures in finance, technology, and critical infrastructure.
  2. Given the Lazarus Group's history of supply chain attacks, it's crucial for developers to adopt a multi-layered defense strategy, as outlined, to safeguard their open source projects from potential infiltration and long-term compromises.
