Destination hostnames are assembled by.join(\"\") of split substrings to defeat static string scanning, and a dnsChunked() routine reassembles a base64 payload from numbered TXT DNS records (c.<domain>, 0.<domain>, 1.<domain>,...) as a fallback delivery channel. The package advertises itself as a menu-provider library and performs no such function; the only observable effect of installing/importing it is delivery and execution of an opaque remote binary on the installer's host.\n","affected":[{"package":{"ecosystem":"npm","name":"eacq-acq-menu"},"versions":["35.2.1"],"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":"_adapter.js","sha256":"9e6e8986fb7ba75ea2da8170b63d41e64b16e41e8f0d12631900f804ac433230","tlsh":"86a1539b026960184bb0d7e4861b8816f65bf6633781c684fbac69944f7752482b2efc"}],"package_integrity":[{"filename":"eacq-acq-menu-35.2.1.tgz","hashes":{"sha1":"0dd3e0620538a018276d190112450752130f23e2","sha512_sri":"sha512-RbJhJgrhCzzypjKEWWA0UEv4+JpHMVQLsQjgWb4lNqRksBimnywY2gGO7H41HJcGE7CD8StTAMZ/PetnqI4QSA=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/eacq-acq-menu/v/35.2.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015581","import_time":"2026-08-05T15:19:59.049851607Z","modified_time":"2026-08-05T15:08:18Z","sha256":"ae7929c06f789a6fc910fd4ce4697fd5d32f06b55a0c9b5e406110f90676c239","source":"amazon-inspector","versions":["35.2.1"]}]}}
