On `npm install`, the postinstall hook collects host identifiers (hostname, username, platform, arch, cwd, node version, pid, all non-internal IP addresses, uptime, package name) and POSTs them as JSON to /b. On `require()` of the package main, the module beacons the same host, then polls /c every 30 seconds for JSON commands and executes the `c` field via child_process.exec, POSTing stdout/stderr back to /r. A source comment self-identifies the module as a stealth typosquat agent, while package.json advertises only a generic \"small utility\" description.\n","affected":[{"package":{"ecosystem":"npm","name":"@prime0/pcomatch"},"versions":["1.0.0"],"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":"postinstall.js","sha256":"f96920db8aa0d72723e7eab7dc5319f4395a201f8eba307b4f81974730c1d75c","tlsh":"571165e00191a6293222a1f1ca5f150917e9e4101201fe98f83cd285bff4e7c07f69ec"},{"path":"index.js","sha256":"a7fc4e3167420ca41e89f929a9721a63761e20c83b555338d91580d46e3dd3f1","tlsh":"ff4142eb91952124a17371f4ca5f64082bbad16202439e98bc2ce385af7493c072adfc"}],"package_integrity":[{"filename":"pcomatch-1.0.0.tgz","hashes":{"sha1":"1169c8d460a4cd79a384a0fdfe155ef5fc2f346e","sha512_sri":"sha512-p7NofNwT8UfpWnHQCH3C2appuPLy2YUEjcIy3Z4tNEJFXW438C+Gcf6h6Oigi7nfqm00a2Hv0Db55NNMkxaJGA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@prime0/pcomatch/v/1.0.0"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-020073","import_time":"2026-09-16T06:31:14.494431104Z","modified_time":"2026-09-16T06:27:31Z","sha256":"08299e41eb4feb9e324854bf5cd3386e6e52696b4b11443254374897a1ad3816","source":"amazon-inspector","versions":["1.0.0"]}]}}
