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.\n","affected":[{"package":{"ecosystem":"npm","name":"boxy-docusaurus-plugin-content-docs-light"},"versions":["35.3.7"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"_ext.js","sha256":"1f1bfd4f6734a59178e42c2a13af8d02ad415143331d48b61714913541583398","tlsh":"88a1b95a12a670198bb097e4871b9416f65bf66337c0c2c4f75ca9885f7212483b2efc"}],"package_integrity":[{"filename":"boxy-docusaurus-plugin-content-docs-light-35.3.7.tgz","hashes":{"sha1":"8d770e543fe830650e58d18a49496ae0a20c14a9","sha512_sri":"sha512-t9kOPIxV82Pa6L6TNDMpGlR3mpcrQyhkiYauK+2das464ZKjaj1PbfeOOZ8y4XxDizcOq+BPPt/4VjPbOj8FjQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/boxy-docusaurus-plugin-content-docs-light/v/35.3.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015347","import_time":"2026-08-05T15:19:46.269036681Z","modified_time":"2026-08-05T14:33:17Z","sha256":"282deb7b97e943caa32f55b14ac302a247a129edb04419d744f01b62666beaae","source":"amazon-inspector","versions":["35.3.7"]}]}}
