The destination is not a registry, vendor SDK host, or documented service — it is an unrelated third-party domain bound to a POST in install/load-reachable code. The combination of system enumeration (hostname, homedir, child_process), filesystem inspection, and a hardcoded non-publisher exfiltration endpoint is the canonical host-information stealer fingerprint and provides direct attacker benefit (host fingerprinting + arbitrary collected data shipped off-host).\n","affected":[{"package":{"ecosystem":"npm","name":"pc-optimizer"},"versions":["1.0.1","1.0.2","1.0.9"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"evidence_files":[{"path":"collect.js","sha256":"463735e1a5b9150efad9ef66856033363d7ffb55490e84d1bf450c0e1406ef4d","tlsh":"44a21e5b14cb351ac747e70ad7670014ad88abb3b113bb41bb8c9bd41f2ad2662d09f9"}],"package_integrity":[{"filename":"pc-optimizer-1.0.1.tgz","hashes":{"sha1":"d138178d30e19ce7dacabef112775241a5ff4be1","sha512_sri":"sha512-rRfMT31QEXwhKzT/VbD616FealDguzqCy30jfl1TUCpujTdSXoLbeRKbwpZLGfuZVdueqx2QYRu7UFobVUkCCw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/pc-optimizer/v/1.0.1"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/pc-optimizer/v/1.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/pc-optimizer/v/1.0.9"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-005748","import_time":"2026-06-11T14:48:05.794332855Z","modified_time":"2026-06-11T13:28:04Z","sha256":"9f3f55c554f0b1b48f8ebaa1b8ee6a9d005c972fa06bef7c9727946e5d422aa4","source":"amazon-inspector","versions":["1.0.1"]},{"id":"IN-MAL-2026-005750","import_time":"2026-06-11T14:48:05.874007514Z","modified_time":"2026-06-11T13:28:07Z","sha256":"f046d16052b9121c55f2fd5e6eb2be90ce24e7b007efca3c2a9e7f64dab8f6bf","source":"amazon-inspector","versions":["1.0.2"]},{"id":"IN-MAL-2026-005749","import_time":"2026-06-11T14:48:05.844910927Z","modified_time":"2026-06-11T13:28:05Z","sha256":"f1dd847960d4aa149ddf901c3b85fa93f3ef2b50d5dfeb64ba3b4599f23ed3aa","source":"amazon-inspector","versions":["1.0.9"]}]}}
