Do not edit below this line.=-_\n\n## Source: amazon-inspector (bcd5c58bd9b678ac91c87dbb7f9a1d2318c67cd3754d643550c7674c903186de)\nOn require, this package loads _ext.js and lib/telemetry.js which fetch a platform-specific opaque binary from a rotating list of attacker-controlled Cloudflare Workers hosts (oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru. The fetched bytes are written to /var/tmp or %TEMP% under a disguised name (`.cache_<hex>`, `dotnet_diag_<hex>.exe`), chmodded to 0o755, and spawned detached via `/bin/sh -c \"<path> &\"` or `cmd.exe` with stdio ignored. Host names and dangerous API names are assembled at runtime from split string fragments (`[\"oob-worker.cf100-416.wo\",\"rkers\",\".de\",\"v\"].join(\"\")`, `require(\"child_\" + \"process\")`, `fs[\"chmod\"+\"Sync\"](...)`) to evade static scanners. A mtime-based stamp file at /tmp/.analytics_state and DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK env checks gate execution to at most once per TTL, reducing repeat-analysis and sandbox detection. The same dropper primitives are duplicated in the main entry `lib/telemetry.js` under an 'Analytics SDK' cover story so the payload fires even if _ext.js is removed. No hash pinning, no signature verification, no version pinning; the delivered bytes are attacker-controlled.\n","affected":[{"package":{"ecosystem":"npm","name":"sme-rko-finance-front-operations-overnight"},"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":"_ext.js","sha256":"c2750bcfe975430c9b8fe3e307894898fbc47dd862ded81792216f09f899e07f","tlsh":"9ca1b65916fb301803d2a2d4461f541671dfe69333c4d9d4fb4ca6944faa26883b39ed"},{"path":"lib/telemetry.js","sha256":"1c495033af17a3cb6cc47d5abc95950cd86f25a7795d1da5e174d2c3e6efedef","tlsh":"5173304966fb10214263b0685fab40437635c4072a4eed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"sme-rko-finance-front-operations-overnight-35.8.1.tgz","hashes":{"sha1":"db3e10d6df4cf5975cb970eed2af19a17400dc8b","sha512_sri":"sha512-qhvvNX60njRRaJ+PArYZFBS32ldx0+FOIfyK/LA13kUxmC2MI9CSRYpRWOGLg+xLQ4xkDB+bUIhyi2VD90+uNQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/sme-rko-finance-front-operations-overnight/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017145","import_time":"2026-08-08T00:53:06.708633487Z","modified_time":"2026-08-08T00:44:23Z","sha256":"bcd5c58bd9b678ac91c87dbb7f9a1d2318c67cd3754d643550c7674c903186de","source":"amazon-inspector","versions":["35.8.1"]}]}}
