Every version was published to cause harm.\n\nTask:\n1. Search this repository's dependency manifests and lockfiles for the package, including transitive dependencies.\n2. If it is present, remove it, regenerate the lockfile with the project's package manager, and replace whatever it was used for.\n3. List any CI runners, developer machines or containers that installed it, so their secrets can be rotated.\n4. If the package is not used anywhere, say so and change nothing.\n\nReference: https://insights.sbomify.com/MAL-2026-13041/ (Markdown: https://insights.sbomify.com/MAL-2026-13041/index.md)","id":"MAL-2026-13041","markdown":"https://insights.sbomify.com/MAL-2026-13041/index.md","name":"MAL-2026-13041","record":{"aliases":[],"analysis":null,"analysis_generated_by":null,"assigner":null,"cpe":[],"cvss":{"score":null,"severity":null,"source":null,"vector":null,"version":null},"cwes":[],"description":"boxy-docusaurus-plugin-content-docs-light@35.3.7 executes a dropper on require. index.js loads _ext.js, which reconstructs destination hostnames at runtime from split string arrays to resolve C2 hosts including oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, and oob-worker.cf103-070.workers.dev, with DNS TXT fallback across sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. It downloads a platform-specific binary via https.get, writes it to /var/tmp or %TEMP% under decoy names (dotnet_diag_*.exe,.cache_*,.analytics_state), chmods it 0755, and spawns it detached through /bin/sh -c or cmd.exe. No hash or signature verification is performed, the destinations are not publisher-controlled and are obfuscated via string-array reconstruction, and env-var opt-outs are used to skip execution in sandboxes. The package name mimics @docusaurus/plugin-content-docs, but the shipped code has no relation to the documented plugin — its only effect on require is fetch-and-execute of an attacker-controlled binary.","ecosystems":["npm"],"exploits":{"exploitdb":null,"first_seen":null,"github_poc":null,"max_poc_stars":null,"metasploit":null,"nuclei":null,"refs":[],"tier":null},"has_fix":false,"headline":"Malicious code in boxy-docusaurus-plugin-content-docs-light (npm)","id":"MAL-2026-13041","indexable":true,"kev":null,"kind":"malicious","links":{"ecosystem":"npm","product":null,"products":[],"type":null,"year":"2026"},"n_packages":1,"n_references":null,"packages":[{"ecosystem":"npm","fixed":[],"introduced":[],"last_affected":[],"package":"boxy-docusaurus-plugin-content-docs-light","purl":"pkg:npm/boxy-docusaurus-plugin-content-docs-light","source":"MAL-2026-13041"}],"products":null,"published":"2026-08-05","related":[],"sources":[{"class":"attribution","licence":"Apache-2.0","name":"OpenSSF Malicious Packages","prefix":"MAL"}],"ssvc":{"automatable":null,"exploitation":null,"technical_impact":null},"state":null,"updated":null,"vendors":null},"summary":null,"url":"https://insights.sbomify.com/MAL-2026-13041/"}
