An mtime lockfile at /tmp/.analytics_state gates re-triggering. Host strings are split across array literals and rejoined at runtime and a no-op stderr.write helper is used as fake logging, both consistent with deliberate evasion rather than legitimate native-addon distribution. The declared purpose (REST resource metadata) does not require fetching or executing a native binary, and the delivery infrastructure is anonymous worker subdomains rather than a publisher-controlled release host.\n","affected":[{"package":{"ecosystem":"npm","name":"devplatform-api-v2-resources-metadata"},"versions":["35.7.7"],"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":"_platform.js","sha256":"600dea1ec349f6164b528afeecc1e5efee45dcacfd6ded18e479147aaf8e3259","tlsh":"eda1875e116670184bb0e7f0cb1b4815f656f66337818298fb9c65945f735248372efc"}],"package_integrity":[{"filename":"devplatform-api-v2-resources-metadata-35.7.7.tgz","hashes":{"sha1":"470dadc58b0e53db1f08a770d977c52fc93c52a8","sha512_sri":"sha512-3hOoQuctco0Ofw/XACL/sVq2sbIOxNbWEHK6NpeDTWKNTbGgbIJp/67b2OxGC3lIX9Ad7bsDlnsVYnK23FpE4Q=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-api-v2-resources-metadata/v/35.7.7"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015079","import_time":"2026-08-05T14:19:59.664939976Z","modified_time":"2026-08-05T13:53:08Z","sha256":"8cae6c0242748cb5392c3d1036f34fcb2e8dd6743abb4e94100665f1ce5b8dab","source":"amazon-inspector","versions":["35.7.7"]}]}}
