Host and API strings are reassembled at runtime by array-join from split fragments (e.g. [\"oob-worker.cf103-070.workers.de\",\"v\"].join(\"\"), ['sdk.dl.wel','1.ru'].join(\"\"), \"chmod\"+\"Sync\") to evade static matching. The fetched bytes are written to /tmp or %TEMP% under a disguised name (.cache_<hex> or dotnet_diag_<hex>.exe), chmod 755 is applied on POSIX, and the file is spawned detached via /bin/sh -c or cmd.exe with.unref(). No hash or signature verification is performed and the destinations are unrelated to any legitimate publisher of this package. In addition, lib/telemetry.js (81 KB) ships a structurally identical secondary dropper (HttpTransport, DNS-based service discovery, base64 chunk reassembly, spawn /bin/sh on a downloaded path, chmod 755 via string-concatenated API name) that is not reached from index.js in this version but is present in the tarball.\n","affected":[{"package":{"ecosystem":"npm","name":"boxy-global-modules-webpack-plugin"},"versions":["35.5.5"],"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":"_loader.js","sha256":"4672c7c697c9c43aa24e58523d985afa7bb63ec58d472cb4db26bdb6fcf0e265","tlsh":"dca184aa057670084bb0e7e5c617541af55af6633280c298fb9ca5d80fb3124c3b2efc"},{"path":"lib/telemetry.js","sha256":"1afdb8a99f82de3759930b2047cde9bdbd2addc9ed6cfd44294578c8e7360f1f","tlsh":"20835055566a102186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffd"}],"package_integrity":[{"filename":"boxy-global-modules-webpack-plugin-35.5.5.tgz","hashes":{"sha1":"d89c1ec12cbb8349dc443b258d7a4a3d76608f99","sha512_sri":"sha512-EINA2b/WMK1CWYfoO6L2zXkjgqAmZMV0O9FUy9k6Vnj0ppEVXlQDAO1OhG0xhWUeHUAV+kbStgUQ9PmZqN4oAw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/boxy-global-modules-webpack-plugin/v/35.5.5"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015320","import_time":"2026-08-05T15:19:44.694089493Z","modified_time":"2026-08-05T14:29:22Z","sha256":"6ce609c23d8c990c21c16692270dbb62589c6f63e716994c31e5ed4f466dcad7","source":"amazon-inspector","versions":["35.5.5"]}]}}
