{"id":"MAL-2026-16111","summary":"Malicious code in etoro-aggregator (npm)","details":"\n---\n_-= Per source details. Do not edit below this line.=-_\n\n## Source: amazon-inspector (d7d5f0fb8c06c23afad28686a3d3d689dfc5a3786c73bff2c569fd8b55f2b4ad)\nThe package's preinstall.js lifecycle script executes automatically on `npm install` and performs reconnaissance on the installer host. It collects hostname, username, current working directory, platform, and the output of OS commands including `whoami /all`, `ipconfig /all` / `ifconfig`, `tasklist` / `ps aux`, directory listings of `/`, `C:\\`, and the user's home, and a dump of environment variables. The collected data is transmitted via HTTP GET and POST to the hardcoded bare IP endpoint `http://209.126.81.147/etoro-nuget-verify1f8eaa57a875/v4/...`. The package's declared main is an empty stub and its description (\"Internal service client library\") combined with the implausibly high version number `99.0.2` is consistent with a dependency-confusion attack targeting an internal `etoro-aggregator` name. The manifest plus the preinstall script constitute the entire payload; installing the package leaks installer host identity, network configuration, filesystem structure, and environment variables (which routinely contain credentials and tokens) to an attacker-controlled endpoint.\n","modified":"2026-09-11T18:45:05.148846978Z","published":"2026-09-10T04:44:38Z","database_specific":{"malicious-packages-origins":[{"versions":["999.0.0"],"id":"IN-MAL-2026-019913","import_time":"2026-09-10T05:18:06.154710325Z","modified_time":"2026-09-10T04:44:38Z","sha256":"6e7805793fe0fa0f03f018a31574ec577e87f249231d9ada54cdf052395a65d1","source":"amazon-inspector"},{"source":"amazon-inspector","versions":["99.0.2"],"id":"IN-MAL-2026-019995","import_time":"2026-09-11T18:21:31.876442289Z","modified_time":"2026-09-11T17:55:12Z","sha256":"d7d5f0fb8c06c23afad28686a3d3d689dfc5a3786c73bff2c569fd8b55f2b4ad"},{"sha256":"fed6b767c0c79e7ff5fde78cb9a70e9a5d734eb7dbd4b0c6587d2401b3b99394","source":"amazon-inspector","versions":["99.0.0"],"id":"IN-MAL-2026-020000","import_time":"2026-09-11T18:21:32.129840182Z","modified_time":"2026-09-11T17:55:51Z"}]},"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/etoro-aggregator/v/999.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/etoro-aggregator/v/99.0.2"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/etoro-aggregator/v/99.0.0"}],"affected":[{"package":{"name":"etoro-aggregator","ecosystem":"npm","purl":"pkg:npm/etoro-aggregator"},"versions":["999.0.0","99.0.2","99.0.0"],"database_specific":{"cwes":[{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"cweId":"CWE-506","description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code"},{"description":"The product contains code that appears to be malicious in nature.","name":"Embedded Malicious Code","cweId":"CWE-506"}],"indicators":{"package_integrity":[{"hashes":{"sha512_sri":"sha512-FJgBrtluocgzTKx5Y5QuyJfnttviV20BaXEMYtykHkgdLI+BCScq6JVA2EF2N0NIAZxxieTSrsGabKdwbAXnGQ==","sha1":"672fb109116e914c286f98c26419993208a582d7"},"filename":"etoro-aggregator-999.0.0.tgz"}],"evidence_files":[{"tlsh":"ebe027f4118ca6683ccc01c4636b191ed4dfc705bcdec8c04a55d78587b15f1d6115f0","path":"preinstall.js","sha256":"bee47062733940943fd3a66654f0258135fd62911674304ccac11a43226b5f58"}]},"source":"https://github.com/ossf/malicious-packages/blob/main/osv/malicious/npm/etoro-aggregator/MAL-2026-16111.json"}}],"schema_version":"1.9.0","credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"}]}
