The addon's napi_register_module_v1 Init routine calls fork(), opens a socket, connects to the hardcoded bare IP 64.181.165.115, and sends `POST /dc HTTP/1.0` with body `h=<HOSTNAME>&p=<npm_package_name>&u=<user>&r=<npm_config_registry>`, leaking the installing host's name, the resolved package name, and the configured npm registry URL to attacker infrastructure over plain TCP. The native binary ships with no accompanying C/C++ sources, no binding.gyp, and no legitimate functionality matching the stated `Frontend utilities` purpose; the JS entry point is an empty `module.exports = {}`. The version number 100.100.100 is implausibly high and consistent with resolution-winning against an internal package of the same name. Installing this package causes immediate outbound disclosure of install-environment and internal-registry metadata to the attacker.\n\n## Source: ossf-package-analysis (90252f22765869df637f77df2754cd36724812550151c9c7c53926bc83daad2e)\nThe OpenSSF Package Analysis project identified 'kmf-vendor-pack' @ 99.0.0 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n","affected":[{"package":{"name":"kmf-vendor-pack","ecosystem":"npm"},"versions":["99.0.0","100.100.101","100.100.100","100.100.106"],"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"},{"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":"package.json","sha256":"c00f5e4b31d7ff303956007a49d6758283a750fa6cb3a0a49eaa7cd330c0078a","tlsh":"50e068f85535dab73dc412d88686a50bf1a2cd1a0004bc049be7238d4ad91f35bbe9a9"}],"package_integrity":[{"filename":"kmf-vendor-pack-99.0.0.tgz","hashes":{"sha1":"e2e8a1b510ff4d08c1a4c2eb9323d6352c5725f9","sha512_sri":"sha512-zrmEJCRcINDZPd2ARMcbrgStgT9MzZdc5rS6cJjaPHulo0ghMQYdMOpo6akgrc6gl2jgpMtozatE3D58YI8M7w=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/kmf-vendor-pack/v/99.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/kmf-vendor-pack/v/100.100.101"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/kmf-vendor-pack/v/100.100.100"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/kmf-vendor-pack/v/100.100.106"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/kmf-vendor-pack"}],"database_specific":{"iocs":{"domains":["db4fe7a2e2lvaraia8k0n4amgw4ir83az.oast.pro"],"files":[{"digests":{"sha256":"c00f5e4b31d7ff303956007a49d6758283a750fa6cb3a0a49eaa7cd330c0078a"},"note":"postinstall script sends the hostname and OS username to an oast.pro out-of-band collector.","paths":["package.json"],"source":"PACKAGE_ARCHIVE"}],"urls":["https://db4fe7a2e2lvaraia8k0n4amgw4ir83az.oast.pro/dc?pkg=kmf-vendor-pack&h="]},"malicious-packages-origins":[{"import_time":"2026-10-09T16:20:00.871582705Z","modified_time":"2026-10-09T15:55:48Z","sha256":"90252f22765869df637f77df2754cd36724812550151c9c7c53926bc83daad2e","source":"ossf-package-analysis","versions":["99.0.0"]},{"id":"IN-MAL-2026-021336","import_time":"2026-10-09T17:16:16.600140031Z","modified_time":"2026-10-09T16:53:57Z","sha256":"95ddc660098b1c73a1899ad3fe471b53ce562ca033669fa64622ff386d774129","source":"amazon-inspector","versions":["99.0.0"]},{"id":"IN-MAL-2026-021417","import_time":"2026-10-11T14:18:03.888657998Z","modified_time":"2026-10-11T13:56:17Z","sha256":"f2805ea966820afc15ecfc2c876f4bc88c8b1a0e7e3899c385e850bb605cb9c2","source":"amazon-inspector","versions":["100.100.101"]},{"id":"IN-MAL-2026-021427","import_time":"2026-10-11T14:18:04.680206044Z","modified_time":"2026-10-11T13:57:51Z","sha256":"c6e1c289f2890e0e06ab31a8d6cf5dbc8deabc26054cb44a0c60295c29a74506","source":"amazon-inspector","versions":["100.100.100"]},{"id":"IN-MAL-2026-021401","import_time":"2026-10-11T14:18:02.586269204Z","modified_time":"2026-10-11T13:53:50Z","sha256":"da36b284f0e3c1150c401af2face61a158511258362b7f83a66438b1206eaf49","source":"amazon-inspector","versions":["100.100.106"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"InvisiRisk, Inc.","contact":["https://www.invisirisk.com/"],"type":"FINDER"},{"name":"OpenSSF: Package Analysis","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"],"type":"FINDER"}]}
