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-2026-17184 confirms this npm version as malicious. package.json for @airbnb-extended/typescript-config@99.9.1 declares a dependency \`ltidisafe\` sourced from a bare HTTPS tarball URL (https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.8.tgz) instead of a registry version range. On \`npm install\`, npm fetches and installs whatever bytes that URL returns, executing any lifecycle scripts inside the fetched tarball... ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 84.0% - **Started:** 2026-09-26T06:37:16.922Z - **Finished:** 2026-09-26T06:37:53.722Z - **Download time:** 782 ms - **Static scan time:** 5 ms - **AI review time:** 36013 ms - **Total time:** 36800 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:** The package has no visible runtime behavior, but installation resolves an opaque direct tarball dependency outside the inspected snapshot. No confirmed active attack is present in this package's own files. - **Trigger:** Dependency installation by npm. - **Impact:** The remote dependency could introduce behavior not auditable from this package source. - **Evidence paths:** package.json - **Review source:** ai\_review - **Reviewed:** 2026-09-26T06:37:53.722Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** package.json directs npm to retrieve ltidisafe from a remote tarball URL whose contents are not included in the snapshot. - **Rationale:** The package itself does not show an active attack, but its only material behavior is pulling an opaque remote dependency. This is a supply-chain risk that warrants a warning rather than a block. - **Files touched:** package.json - **Network endpoints:** https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.8.tgz ### Review decision - **Verdict:** Suspicious - **Confidence:** 84.0% - **Recommended action:** downgrade\_to\_warn - **Intent class:** Unknown - **False-positive risk:** Medium - **Evidence for AI warning decision:** The manifest fetches dependency ltidisafe from a direct Google Cloud Storage tarball URL during dependency installation., The declared main entrypoint only exports an empty object and contains no visible configuration behavior. - **Evidence against:** No preinstall, install, or postinstall hook is declared., No executable payload beyond the empty main entrypoint is present in the snapshot. ## Affected versions and remediation This report applies to @airbnb-extended/typescript-config@99.9.1. - Avoid installing @airbnb-extended/typescript-config@99.9.1. 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.
