{"id":"MAL-2026-13141","summary":"Malicious code in dolyame-ui-carousel (npm)","details":"\n---\n_-= Per source details.

A DNS TXT chunked-base64 covert-channel fallback is implemented against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The fetched bytes are written to a hidden/disguised path in /tmp or %TEMP% (`.cache_\u003chex\u003e` on Unix, `dotnet_diag_\u003chex\u003e.exe` on Windows), chmod 0755, and spawned detached via `/bin/sh -c \"\u003cpath\u003e &\"` or `cmd.exe /c start /b`. A stamp file gates re-execution. Cover-story identifiers such as `_NODES`, `analytics_state`, and `DISABLE_TELEMETRY` are used alongside the drop-and-exec logic. The package's declared purpose is a UI carousel component, which has no legitimate need to fetch and execute a native binary from anonymous workers.dev endpoints at import time.\n","modified":"2026-08-05T15:52:42.719303209Z","published":"2026-08-05T15:17:03Z","database_specific":{"malicious-packages-origins":[{"import_time":"2026-08-05T15:20:01.168932585Z","modified_time":"2026-08-05T15:17:03Z","sha256":"99a12afad0ec2643334f24431df3b2ba84584a9569bca025b50ef52feb6b9493","source":"amazon-inspector","versions":["35.3.3"],"id":"IN-MAL-2026-015637"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-carousel/v/35.3.3"}],"affected":[{"package":{"name":"dolyame-ui-carousel","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-carousel"},"versions":["35.3.3"],"database_specific":{"indicators":{"package_integrity":[{"filename":"dolyame-ui-carousel-35.3.3.tgz","hashes":{"sha512_sri":"sha512-2rjGgTqx29EuCLt5kxOtwNS4iI87jDf709kVp7irmAvqdpeCqN58ifkZFSrYXLMvvgxUR3m5I2yvVY67uNaPyw==","sha1":"958dfa1ba33a0a646925c4753b6d8dc937781f42"}}],"evidence_files":[{"path":"_shim.js","sha256":"65117b968e99c8a34938eacde57d46893d35df4a02ec79914d087722208c6e7e","tlsh":"4da19696056970088b709be5cb275415f55bf6633780c288fb9ca5981f7662483b3efc"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-carousel/MAL-2026-13141.json","cwes":[{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}]}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
