Malicious code in @dransay/address-validation (npm)

@dransay/[email protected] is a dependency-confusion probe claiming the internal `@dransay/*` namespace, not an identified public package. 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 the package name in the request; npm account `0xamino_hunter` published it on 2026-10-08. --- _-= Per source details. Do not edit below this line.=-_ ## Source: amazon-inspector (189df4f2830e64a9cfbd0bed6ae8357aff16dc5496d83c3e5e4bd9457b536fa7) @dransay/[email protected] declares a preinstall script (`node beacon.js`) that fires on `npm install` and performs a DNS lookup plus HTTPS GET to a subdomain of the Interactsh collaborator service `oast.site` with the path `/address-validation`. The implausibly high version number (99.0.0) and the preinstall callback are consistent with a dependency-confusion probe: any environment resolving this name reveals its egress IP and the package name to the operator of the collaborator host. No installer secrets, environment variables, or filesystem contents are read; the beacon transmits only install metadata (source IP, package name, DNS resolver). No code is fetched or executed from the remote host, and no persistence is established. ## Source: ossf-package-analysis (82ababa5637b2f53f5087a161eeba1b6ca6ddba6d31ebb7842614bf0da119fa7) The OpenSSF Package Analysis project identified '@dransay/address-validation' @ 99.0.0 (npm) as malicious. It is considered malicious because: - The package communicates with a domain associated with malicious activity.
