The downloaded binary is written to /var/tmp or %TEMP% under cover-story names such as.cache_<hex> or dotnet_diag_<hex>.exe, chmodded to 0755, and spawned detached via cp.spawn('/bin/sh', ['-c', fp+' &']).unref(). Obfuscation includes string-splitting of the child_process require ('child_' + 'process'), array-join reassembly of destination hostnames, and reflective property access such as fs['chmod'+'Sync']. A second dropper stage with the same primitives is shipped in lib/telemetry.js. A package advertised as a UI dropdown has no legitimate reason to fetch and execute platform-specific ELF/Mach-O/EXE payloads at import time.\n","affected":[{"package":{"ecosystem":"npm","name":"dolyame-ui-dropdown"},"versions":["35.6.2"],"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":"ce7c8621fabf5e3115d80789471e8b7be654a9243ee2d1d0548990931fa3363a","tlsh":"e5a1a69a166a30184bb0d7e4c717441af65bf2633780d181fb9c65941fb613483b1efc"},{"path":"lib/telemetry.js","sha256":"dfd02aa0f18f07798ea5d3e06af39bcbb0d05e2611a18b2a4b58017436898ae0","tlsh":"63835055566a242186b2b368df234107ff3685272643429dbafc82dc1fbd72092a5ffc"}],"package_integrity":[{"filename":"dolyame-ui-dropdown-35.6.2.tgz","hashes":{"sha1":"3d77e198e1fbc28664e29bd6fbf37357c788656a","sha512_sri":"sha512-anmqlA3fIjaqT/lUIKvXFCjLEI9m8xZflxAuezHIpF8QTGESe4U3VMoaL9nxbBjobmOXE4MBUdOHvBskNf0SWg=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-dropdown/v/35.6.2"}],"credits":[{"name":"Amazon Inspector","type":"FINDER","contact":["inspector-research@amazon.com"]}],"database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015619","import_time":"2026-08-05T15:20:00.448977981Z","modified_time":"2026-08-05T15:14:16Z","sha256":"78e2cf3af799e05f20494aba04b5d85aa1335bce541af4cb13aa715a2cda6ea5","source":"amazon-inspector","versions":["35.6.2"]}]}}
