The beacon fires automatically on `npm install` without user opt-in. The package name resembles Google's platform-ai code-assist tooling, consistent with a dependency-confusion or typosquat reconnaissance beacon confirming code execution on installer build machines.\n","modified":"2026-08-19T04:00:18.305062660Z","published":"2026-08-19T03:42:04Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-018333","import_time":"2026-08-19T03:49:30.77463102Z","modified_time":"2026-08-19T03:42:04Z","sha256":"093f28fd5542ee841027c5b3dc6917a42ac13dd3e0e1d3bf334e87b823886d3c","source":"amazon-inspector","versions":["1.0.0"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/code-assist-mcp/v/1.0.0"}],"affected":[{"package":{"name":"code-assist-mcp","ecosystem":"npm","purl":"pkg:npm/code-assist-mcp"},"versions":["1.0.0"],"database_specific":{"cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"filename":"code-assist-mcp-1.0.0.tgz","hashes":{"sha1":"571ecfda96d4025441fc58a89bed822f88ed9dfe","sha512_sri":"sha512-rtTkgzG8/M4b8ucukgwGS7b/V1oHaPmh1qcDdTeW6xrrmC2cmHLSR4ZpIZLdP9QkFicrW2r9+K9nREtn8SVNuA=="}}],"evidence_files":[{"path":"postinstall.js","sha256":"fd38fe87aa69c75ba9acb7afda092e7f3f84207e828dbb6a3d5efe0dd510c78c","tlsh":"9301fec5d1b95a761bb8a29028f0af0693faf223370620b57ac444a92f8d0f900311ad"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/code-assist-mcp/MAL-2026-14233.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
