The package name mimics a corporate UI library but the code performs system reconnaissance and exfiltration of installer host data, with no legitimate UI-library functionality indicated at the entry point. Any installer or build system that pulls this package will leak the machine's user and hostname to an attacker-controlled Telegram bot on require/load. Three independent static detections (child-process + https exfiltration, nodejs system exfiltration, simple sysinfo exfiltration) corroborate a single small file implementing a classic recon beacon.\n\n## Source: ossf-package-analysis (e04e7522e73249638f1fd02bc8b13369626291222da0a2ba1612bbcba6a14bad)\nThe OpenSSF Package Analysis project identified '@corpweb-ui/wmkt-library' @ 99.99.11 (npm) as malicious.\n\nIt is considered malicious because:\n\n- The package communicates with a domain associated with malicious activity.\n","modified":"2026-05-13T20:21:26.246468Z","published":"2026-04-03T08:18:07Z","database_specific":{"malicious-packages-origins":[{"sha256":"e04e7522e73249638f1fd02bc8b13369626291222da0a2ba1612bbcba6a14bad","versions":["99.99.11"],"modified_time":"2026-04-03T08:18:07Z","import_time":"2026-04-03T09:49:15.440649535Z","source":"ossf-package-analysis"},{"sha256":"7edd228a2ceff9b781a1fa9bf0f6a32f96b742da2d2eee702c009c091ecee3d6","versions":["99.99.11"],"modified_time":"2026-04-07T14:24:50Z","import_time":"2026-04-07T14:39:22.783084434Z","source":"amazon-inspector"},{"sha256":"bbd8ffd61a62a041699d312b4988f76acecc9d1318b91105bd80c8ae06760dff","versions":["99.99.11"],"import_time":"2026-05-13T20:10:56.906010751Z","modified_time":"2026-05-12T19:03:07Z","id":"IN-MAL-2026-002440","source":"amazon-inspector"},{"sha256":"dfd12ddf708e12b032513bcf667e459df772f642106507d1798d95ee81f6cbe2","versions":["99.99.12"],"import_time":"2026-05-13T20:10:57.014058326Z","modified_time":"2026-05-12T19:03:07Z","id":"IN-MAL-2026-002441","source":"amazon-inspector"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/@corpweb-ui/wmkt-library/v/99.99.11"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/@corpweb-ui/wmkt-library/v/99.99.12"}],"affected":[{"package":{"name":"@corpweb-ui/wmkt-library","ecosystem":"npm","purl":"pkg:npm/%40corpweb-ui/wmkt-library"},"versions":["99.99.11","99.99.12"],"database_specific":{"cwes":[{"name":"Embedded Malicious Code","description":"The product contains code that appears to be malicious in nature.","cweId":"CWE-506"},{"name":"Embedded Malicious Code","description":"The product contains code that appears to be malicious in nature.","cweId":"CWE-506"}],"indicators":{"evidence_files":[{"sha256":"f35fd3dd7a6cf30b117683de7a6839c36716340ea00af4b29dc2305dd669d3a5","path":"index.js","tlsh":"45210fda063d5d2222a254c39257b01ffa830913a254fda17caa43a19fd70f183597fa"}],"package_integrity":[{"hashes":{"sha512_sri":"sha512-ezIDlk6h17fFD249yujuZU71tPIRHKKN1U6VkFjvRTLPM9E5RGOdzIGe1kv/uMIVA0dEwGLocEeeG6GlttAawg==","sha1":"ade827fd1bf51dc8446b1a877e1d19db623b6d2f"},"filename":"wmkt-library-99.99.11.tgz"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/@corpweb-ui/wmkt-library/MAL-2026-2446.json"}}],"schema_version":"1.7.5","credits":[{"name":"Amazon Inspector","contact":["actran@amazon.com"],"type":"FINDER"},{"name":"OpenSSF: Package Analysis","contact":["https://github.com/ossf/package-analysis","https://openssf.slack.com/channels/package_analysis"],"type":"FINDER"}]}
