LPM AI assessed this version as suspicious; the assessments disagree. - **Verdict:** Malicious - **Product-default install policy:** Block - **Firewall policy:** Trusted malware advisory block - **Public report status:** Published - **Threat category:** Malware - **Selected version:** 99.0.0 - **Selected version is latest:** Yes - **Analysis source:** OpenSSF/OSV Malicious Advisory (OpenSSF/OSV) OpenSSF/OSV malware advisory MAL-2026-17668 identifies this version as malicious and supplies the Firewall block. LPM AI assessed this version as suspicious; the assessments disagree. Independent AI assessment: suspicious. LPM AI assessed this version as suspicious; the assessments disagree. OpenSSF/OSV advisory MAL-2026-17668 confirms this npm version as malicious. @dransay/address-validation@99.0.0 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... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 88.0% - **Started:** 2026-10-12T06:38:08.575Z - **Finished:** 2026-10-12T06:38:46.117Z - **Download time:** 2041 ms - **Static scan time:** 8 ms - **AI review time:** 35492 ms - **Total time:** 37542 ms The recorded confidence comes from the underlying analysis. Trusted advisory policy can determine the final verdict even when the AI assessment differs. ## Security analysis ### Published attack-surface review - **Summary:** Installation triggers an outbound beacon to a fixed external host. The request reports the package name, but no sensitive data collection was found in the inspected source. - **Trigger:** The package's preinstall lifecycle hook runs. - **Impact:** The recipient can observe that this package installation occurred; the source does not show transmission of credentials or system data. - **Evidence paths:** package.json, beacon.js - **Review source:** ai\_review - **Reviewed:** 2026-10-12T06:38:46.117Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** beacon.js sends a DNS lookup and HTTPS GET to a fixed oast.site host, with the package name in the request. - **Rationale:** The automatic external beacon creates a real but limited install-time disclosure, while the inspected payload contains only the package name. Authorization remains unverified, so this warrants a warning rather than a block. - **Files touched:** package.json, beacon.js - **Network endpoints:** db3klhbi6i9hark1kegg174t38h33b6wt.oast.site ### Review decision - **Verdict:** Suspicious - **Confidence:** 88.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Dangerous Capability - **False-positive risk:** Medium - **Evidence for AI warning decision:** package.json runs beacon.js automatically during preinstall., beacon.js performs DNS lookup and HTTPS GET to a fixed oast.site host, sending the package name; the request errors are suppressed. - **Evidence against:** The inspected request contains only the package name, with no environment variables, files, or system details. ## Affected versions and remediation This report applies to @dransay/address-validation@99.0.0. - Avoid installing @dransay/address-validation@99.0.0. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1.
