Why now
  • Recent campaigns show a rise in malware using alternative JavaScript runtimes like Deno and Bun.
  • Automated attacks like Megalodon rapidly compromise thousands of repositories, escalating risk.
  • The convergence of source code, CI/CD, and AI tools on developer machines increases attack surface and impact.
Why it matters
  • Developer workstations hold critical credentials and access to cloud infrastructure, making them high-value targets.
  • Malware leveraging common development workflows can evade detection and compromise broader environments.
  • Open-source ecosystems and package managers are increasingly exploited for supply-chain attacks.
