{"id":"MAL-2026-13150","summary":"Malicious code in dolyame-ui-container (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (0b0f03a063fb3a6b8c7605612b587eddfefa6181b85b14654ee93f267dd790e1)\nOn require of the package, index.js loads _compat.js, which at module load time downloads a platform-specific binary from hostnames assembled at runtime via string-splitting (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf100-416.workers.dev). If HTTPS mirrors fail, it falls back to a DNS-over-TXT covert channel, resolving TXT records under *.dl.wel1.ru subdomains and base64-decoding the concatenated response into a binary. The fetched payload is written to a disguised path under /tmp or %TEMP% (e.g. dotnet_diag_\u003chex\u003e.exe,.cache_\u003chex\u003e), chmod 0755, and spawned detached via cmd.exe or /bin/sh -c with no hash or signature verification. Environment variable checks (DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, DO_NOT_TRACK) and analytics-styled filenames provide cover. The destinations are not the publisher's infrastructure and the retrieval mechanism is inconsistent with any legitimate distribution channel.\n","modified":"2026-08-05T15:52:47.086139047Z","published":"2026-08-05T15:16:44Z","database_specific":{"malicious-packages-origins":[{"id":"IN-MAL-2026-015635","import_time":"2026-08-05T15:20:01.107978012Z","modified_time":"2026-08-05T15:16:44Z","sha256":"0b0f03a063fb3a6b8c7605612b587eddfefa6181b85b14654ee93f267dd790e1","source":"amazon-inspector","versions":["35.3.7"]}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dolyame-ui-container/v/35.3.7"}],"affected":[{"package":{"name":"dolyame-ui-container","ecosystem":"npm","purl":"pkg:npm/dolyame-ui-container"},"versions":["35.3.7"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"}],"indicators":{"package_integrity":[{"filename":"dolyame-ui-container-35.3.7.tgz","hashes":{"sha1":"0a04c13dc10a0c78f0c54ee1b778171e2c7af53b","sha512_sri":"sha512-YkTBfQEkLZ7pZcAQZUKjzE5IcFORSKjB0xTd9gW3IGUSoo+vyCylim7CVuwjuaB5koRzVAYfjAx3D3AT99Esrg=="}}],"evidence_files":[{"tlsh":"f7a1745a166a30188bb0e7e4c717541af65ae66337c082c4f79c65981f7216483f2efc","path":"_compat.js","sha256":"e3541e692708af1556f34b456d0b4b790fba0efa251ca79da5e2e7634c24d398"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/dolyame-ui-container/MAL-2026-13150.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
