{"id":"MAL-2026-12690","summary":"Malicious code in deposits-common (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (a6d03bd134745bb66c8ba26a5ee1ddd2f9417eab449bd8ca7a4c649064cf38f1)\nindex.js requires./_support on module load. _support.js reconstructs obfuscated hostnames via string split-and-join (oob-worker.cf101-adf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev) and, if HTTPS retrieval fails, falls back to a DNS-TXT covert channel under sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, iteratively resolving numbered TXT records and base64-concatenating the chunks. The resulting bytes are written to /var/tmp or %TEMP% under a disguised name (dotnet_diag_\u003crand\u003e.exe on Windows,.cache_\u003crand\u003e on POSIX), chmod 0755, and spawned detached via spawn(\"/bin/sh\") or spawn(\"cmd\"). No hash or signature verification is performed. The loader honors DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK to remain silent in sandboxes and writes a.analytics_state stamp file to gate re-execution. The delivery infrastructure is unrelated to the package's stated purpose of \"shared primitives\".\n","modified":"2026-08-05T14:36:26.520320272Z","published":"2026-08-05T13:57:33Z","database_specific":{"malicious-packages-origins":[{"source":"amazon-inspector","versions":["35.5.4"],"id":"IN-MAL-2026-015108","import_time":"2026-08-05T14:20:02.884433904Z","modified_time":"2026-08-05T13:57:33Z","sha256":"a6d03bd134745bb66c8ba26a5ee1ddd2f9417eab449bd8ca7a4c649064cf38f1"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/deposits-common/v/35.5.4"}],"affected":[{"package":{"name":"deposits-common","ecosystem":"npm","purl":"pkg:npm/deposits-common"},"versions":["35.5.4"],"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":"_support.js","sha256":"1ea420fa4005831f91b92956888b04a80ea450ff26c87ffe28924874f077756b","tlsh":"e1a1759a12a570198bb0dbe4cb175415f65af6633380c294fa6c79941fb316483b2efc"}],"package_integrity":[{"filename":"deposits-common-35.5.4.tgz","hashes":{"sha512_sri":"sha512-Cy/AZ5EOKG9P351ThDEIoeppl7vQmN4ror+UtfN1CrNMEjjzVltwzaXs+VMGH5OG3MJy++XNNOHhzIWrtEYBbw==","sha1":"612d9bdd175013d18d4dbf4bbbb828241733a1dd"}}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/deposits-common/MAL-2026-12690.json"}}],"schema_version":"1.8.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
