Hostnames and privileged API names are assembled via array.join('') to evade static scans (e.g. require(\"child_\" + \"process\"), _MIRRORS built from [\"oob-worker.cf102-baf.worke\",\"rs.d\",\"ev\"].join('')). The code downloads a platform-specific binary via https.get from oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, and oob-worker.cf101-adf.workers.dev, with a DNS TXT fallback under *.dl.wel1.ru that base64-reassembles the payload. The fetched bytes are written to /var/tmp/.cache_<rand> or %TEMP%\\dotnet_diag_<rand>.exe (masquerading as a dotnet diagnostic file), chmod 0755'd, and spawned detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}) or cmd.exe /c start /b. lib/telemetry.js contains a parallel dropper path (base64 chunk assembly, chmodSync to 0755, cp.spawn('/bin/sh',...)) so execution occurs even if _polyfill.js is removed. The declared 'core infrastructure utilities / telemetry' purpose does not match downloading and executing opaque native binaries from anonymous Cloudflare Workers subdomains.\n","affected":[{"package":{"ecosystem":"npm","name":"sme-rko-finance-front-operations-notifications-models"},"versions":["35.8.1"],"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":"_polyfill.js","sha256":"25eb0d1886d308385793a388fa30b80a07e7795d921c52b52c61ab9f197f36eb","tlsh":"32a1b55a16fb70240693e1d8841f9826749efa5337c4d9c4fb4c66948feb52883b39ec"},{"path":"lib/telemetry.js","sha256":"7ccdf425091e0b66f982944b53bfcdee9aefd6e23892f0250543115a4bc40a36","tlsh":"2c733f4966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-notifications-models-35.8.1.tgz","hashes":{"sha1":"b79038ad5dfd3baed1cf85134767ee679a39e806","sha512_sri":"sha512-CWg/NOr96J6HbPdPvUQXmEmO+KyTAE/6n9AXt5GfFDAOC0fuprj3thEBasH9Q04lluX1a39ze8Nre9N8+qaw/w=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-notifications-models/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017149","import_time":"2026-08-08T00:53:07.008268511Z","modified_time":"2026-08-08T00:44:58Z","sha256":"e1d9ca70f719a1aa76a11ce147945ee7acefdb72bcbf955d1c7cd30a5d9f85e8","source":"amazon-inspector","versions":["35.8.1"]}]}}
