The destination hostnames are assembled at runtime from split string fragments joined together to evade static inspection. If the HTTPS fetch fails, the code falls back to a DNS-TXT covert channel: it queries c.<domain> under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru for a chunk count, iteratively resolves N.<domain> TXT records, concatenates and base64-decodes the responses into a binary. The fetched bytes are written to /var/tmp or %TEMP% under disguised names (.cache_<hex>, dotnet_diag_<hex>.exe), chmod 0755, then executed detached via cp.spawn(\"/bin/sh\", [\"-c\", path+\" &\"], {detached:true}) or the Windows equivalent. The package name, the obfuscation of destinations, the DNS-TXT covert transport, the disguised drop paths, and the detached execution together constitute a remote code execution dropper triggered on any install or import of this package.\n","affected":[{"package":{"ecosystem":"npm","name":"devplatform-hooks"},"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":"_init.js","sha256":"2106a60737eb38f35a9c0ac801ef3026c95b1be0199ea73e82add7991816ad44","tlsh":"c4a1959a16a6701c8bb097f4c6175415f65be6633780c2d4fb9ca9981f7312482b2efc"}],"package_integrity":[{"filename":"devplatform-hooks-35.2.1.tgz","hashes":{"sha1":"b3dc3d630ac927ff3f7343a896414152839703b4","sha512_sri":"sha512-pj0zToAaJlKcdb2riYQz3NK1etjilwXd9S0tueYXNGhIqYB0nPlNQ+vb9O+l9QWJ5Ork+rCVuEpwj3uW47WrCg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/devplatform-hooks/v/35.2.1"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015067","import_time":"2026-08-05T14:19:58.472657149Z","modified_time":"2026-08-05T13:51:25Z","sha256":"03e653399f20fec2b4b40c7c8921090939a1205110d866d23e4b605802cbc75d","source":"amazon-inspector","versions":["35.2.1"]}]}}
