Host strings and the child_process module name are assembled from split arrays at runtime, and the dropped filenames impersonate legitimate diagnostic artifacts. A sibling module lib/telemetry.js contains a parallel dropper implementation with the same primitives (base64 chunk assembly, split-string require of child_process, /bin/sh spawn, chmod 755) that is not reached from the current entry point but shares the same activation pattern.\n","affected":[{"package":{"ecosystem":"npm","name":"cardsmobile-http"},"versions":["35.3.3"],"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":"cfe21fb8a54bb1de4918446affc66c96b0fb5a577a28ef1e05dca551c8470daa","tlsh":"7aa1845a026a70194bb0d7e48717442af65ae6633280c698fb6c65881f77124c3b1dfc"},{"path":"lib/telemetry.js","sha256":"03b5a4064de3e932d3fcf0e19f38ee738c75a03a711381453c418fb744b96781","tlsh":"10835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"cardsmobile-http-35.3.3.tgz","hashes":{"sha1":"e2b00f983e348a45f3ef88d20e37fe1383a21f00","sha512_sri":"sha512-lYD/zp4CBBkzue9DcCPm1RQFbA4IoZnJvdYR7mxsxFq+NSOB2gAgWK+VYugeDWWhpNWyZeJko0Ak3jQ5nhpCyA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/cardsmobile-http/v/35.3.3"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015238","import_time":"2026-08-05T14:20:15.619516598Z","modified_time":"2026-08-05T14:16:55Z","sha256":"1dd23d89483d10aedc3f1a8717673dbae0608df14a168e5d2287e09afe631af7","source":"amazon-inspector","versions":["35.3.3"]}]}}
