🚨 Supply‑Chain Malware Attack Strikes npm and PyPI – Millions of Developers at Risk

Researchers at Aikido Security uncovered a sophisticated supply‑chain malware operation that compromised at least 16 popular packages in the npm and PyPI ecosystems, affecting nearly 1,000,000 weekly downloads.

Context: Why the Software Supply Chain Is a Prime Target

In recent years, open‑source package ecosystems (npm, PyPI, RubyGems, etc.) have become a “highway” for attackers into production environments. Data shows over 90% of modern applications depend on third‑party components, and a single infected package can rapidly spread through CI/CD pipelines across an organization. Techniques like typo‑squatting, code obfuscation, and delayed payloads make static audits insufficient for detection.

Campaign Details from Aikido Security

  1. Attack Vector - The threat actor hijacked maintainers’ accounts to publish malicious versions directly to npm and PyPI. For npm, 16 GlueStack‑related libraries (e.g. @gluestack-ui/utils, @react-native-aria/button) were altered to include a Remote Access Trojan (RAT) in lib/commonjs/index.js.
  2. Malicious Capabilities
    • Screenshot capture and keylogging to harvest credentials and authenticated sessions.
    • Arbitrary shell command execution, including potential file‑wiping scripts.
    • Exfiltration of sensitive files and data to command‑and‑control (C2) servers.
    • Persistence via post‑install scripts and installation into system directories (e.g. %LOCALAPPDATA% on Windows).
  3. PyPI "imad213" Package - Meanwhile, on PyPI, a credential‑harvesting trojan posing as an Instagram growth tool racked up over 3,200 downloads before being removed.

What Makes This Campaign Next‑Level

  • Beyond Cryptocurrency: Unlike prior supply‑chain attacks focused on crypto‑mining, this operation aims at sabotage and data theft.
  • Advanced Obfuscation: Malicious code leverages whitespace tricks and encrypted strings to evade simple scanners.
  • Cross‑Ecosystem Reach: Targeting both npm and PyPI in parallel indicates a resourceful adversary capable of striking multiple developer communities.

Impact and Major Risks

  • Roughly 1 million weekly downloads of compromised npm packages—an enormous window for malware distribution.
  • Operational disruptions and financial losses if malicious scripts delete or encrypt files (e.g. rm -rf * on Linux or PowerShell Remove-Item -Recurse).
  • Exfiltration of critical data (API keys, database credentials) can lead to widespread breaches and subsequent extortion.

Advanced Defense Strategies

  1. Dynamic Inventory - Maintain an up‑to‑date SBOM (Software Bill of Materials) and automate dependency scans on every build.
  2. Multi‑Layered Scanning - Don’t rely on a single tool: combine Snyk, Dependabot, GitHub Advanced Security, and an EDR/IDS to catch anomalous behavior at runtime.
  3. Strict Signature Verification - Enforce PGP‑signed packages and validate cryptographic hashes. Block any unsigned or mismatched package versions in CI/CD.
  4. Isolation & Least Privilege - Run build and runtime processes in containers or VMs with restricted permissions and no direct access to sensitive resources.
  5. Behavioral Monitoring - Set up alerts for unexpected shell executions, unusual API accesses, and screenshot or data exfiltration attempts.

DevSecOps Best Practices

  • Shift Left: Integrate security into coding and build stages, not just after defects become incidents.
  • Collaborative Threat Intelligence: Contribute to and consume OSINT feeds, share Indicators of Compromise (IoCs), and participate in security forums.
  • Continuous Developer Training: Educate teams on typo‑squatting risks, the importance of dependency audits, and manual review techniques for open‑source code.

Conclusion

Supply‑chain malware is no longer a theoretical threat—it’s a daily reality for software development. Every automatically installed component can become the entry point for a sophisticated attack.
