Its `preinstall` hook runs on npm install as `node beacon.js` and sends a DNS lookup and an HTTPS GET to `db3klhbi6i9hark1kegg174t38h33b6wt.oast.site`, using `dransay-unscoped` in the request; npm account `0xamino_hunter` published it on 2026-10-08.\n\n---\n_-= Per source details.

The outbound request discloses the installer's source IP, DNS resolver IP, hostname-derived data, and timestamp to a third-party collaborator host unrelated to any first-party publisher. The package name and implausibly high version (99.0.0) are consistent with a dependency-confusion probe targeting an internal package name. The README self-labels the package as a benign dependency-confusion proof-of-concept; the self-label does not change the behavior — install-time, non-consensual outbound network I/O to a researcher-controlled OAST host that collects installer network identity.\n","affected":[{"package":{"name":"dransay","ecosystem":"npm"},"versions":["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"}],"indicators":{"evidence_files":[{"path":"beacon.js","sha256":"def65592785337a3ce4a18e0af15acf013ab32c97a3b6c390d2782dbb458fe1c","tlsh":"451168ad56e42700b1e9f45494cd01e84b73d1a4844946c0f1cec39b5e5347d17674f7"}],"package_integrity":[{"filename":"dransay-99.0.0.tgz","hashes":{"sha1":"aca0769ba477e971d3dd231bc9914cbeede8dda1","sha512_sri":"sha512-Za78JrpJOW8wN1gBxjRfMcvJGWFYRTdHvOFTEfhuoh1bbh7ruvfRLBJLFnUrnr3uxNjWWUStvE36oPMXS0ITLw=="}}]}}}],"references":[{"type":"PACKAGE","url":"https://www.npmjs.com/package/dransay/v/99.0.0"},{"type":"PACKAGE","url":"https://www.npmjs.com/package/dransay"}],"database_specific":{"iocs":{"domains":["db3klhbi6i9hark1kegg174t38h33b6wt.oast.site"],"files":[{"digests":{"sha256":"c5cc6a9931a5f44a55ce863dd075911b34ffb2fb3cbf1180c5c487a259dea35c"},"note":"preinstall script: node beacon.js","paths":["package.json"],"source":"PACKAGE_ARCHIVE"},{"digests":{"sha256":"def65592785337a3ce4a18e0af15acf013ab32c97a3b6c390d2782dbb458fe1c"},"note":"Executed by the preinstall script of dransay@99.0.0.","paths":["beacon.js"],"source":"PACKAGE_ARCHIVE"}],"urls":["https://db3klhbi6i9hark1kegg174t38h33b6wt.oast.site/dransay-unscoped"]},"malicious-packages-origins":[{"id":"IN-MAL-2026-021227","import_time":"2026-10-08T17:43:20.188351321Z","modified_time":"2026-10-08T17:23:01Z","sha256":"46d06d0ce82913346840f676660d67f9838f48511e58eef793bfe7c52091071f","source":"amazon-inspector","versions":["99.0.0"]}]},"credits":[{"name":"Amazon Inspector","contact":["inspector-research@amazon.com"],"type":"FINDER"},{"name":"InvisiRisk, Inc.","contact":["https://www.invisirisk.com","mailto:research@invisirisk.com"],"type":"FINDER"}]}
