Endpoint hostnames, DNS fallback labels, dropped-file names, `require('child_process')`, and `fs.chmodSync` are assembled from string fragments (e.g., `['oob-worker.','cf99-9b3.workers.dev'].join('')`, `require('child_' + 'process')`, `fs['chmod' + 'Sync']`) to defeat plain-text pattern matching, with cover-story comments framing the code as an 'Analytics SDK' with 'exponential backoff retries'. A marker file `/tmp/.analytics_state` gates re-execution. The declared main entry `lib/telemetry.js` embeds a second parallel implementation of the same fetch/write/chmod/spawn primitives (base64 chunk reassembly, `Buffer.from(chunks, 'base64')`, chmod 0755, `cp.spawn('/bin/sh', ['-c', filePath + ' &'],...)`) dressed as an observability SDK. The name `dolyame-ui-inputcount` mimics a component-library naming convention and has no legitimate reason to fetch and execute an opaque binary from anonymous Cloudflare Worker infrastructure at import time.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-inputcount"},"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":"_helpers.js","sha256":"14da71ffd89002a0b681cff97fafc52bcc31dc786b0672ed973ba7bce519091b","tlsh":"e5a1a61a16fa30140792e5d8891f4816719ef98336c4e8c4fb4ca6995f9b238c3b39fc"},{"path":"lib/telemetry.js","sha256":"c0c650bdd03d5049580ebb4b3ca3e40d413fb9e54444c5014228f7e256b5cf52","tlsh":"2c733f4966fb10214263b0685fbb40437635c4072a4aed5dba9c43ec9f8db3896f1fb9"}],"package_integrity":[{"filename":"dolyame-ui-inputcount-35.8.1.tgz","hashes":{"sha1":"e57b343c59951c729f76cd1e42fdab2a9263bec4","sha512_sri":"sha512-CPsKPnwlRwrqkeohde9KMbDlrj6GTyViNaPlZXIkY70heM6B7El4XWfVg2rvEu3Vj2Vig/wITz/X/yllMIzKaQ=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-inputcount/v/35.8.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-017036","import_time":"2026-08-07T12:51:23.170669994Z","modified_time":"2026-08-07T12:34:37Z","sha256":"e7a3d0d930d73916ee9555c5a2c1ca8596f25a4336041d881f268504ad8fab06","source":"amazon-inspector","versions":["35.8.1"]}]}}
