## Security analysis

### Published attack-surface review

- **Summary:** npm installation resolves a remote tarball dependency whose contents are absent from this package. The inspected package code has no runtime behavior or lifecycle execution.

- **Trigger:** npm install of gunzip-js@99.9.1

- **Impact:** Uninspected dependency code can execute through its own install/runtime behavior.

- **Evidence paths:** package.json, index.js

- **Review source:** ai\_review

- **Reviewed:** 2026-08-15T16:04:02.157Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** remote tarball dependency fetch

- **Rationale:** Source inspection confirms an unpinned remote tarball dependency but no malicious behavior in the package files themselves. Warn because installation introduces an uninspectable staged dependency.

- **Files touched:** package.json, index.js

- **Network endpoints:** https://ltidi.storage.googleapis.com/depenconf/ltidisafe-3.7.2.tgz

### Review decision

- **Verdict:** Suspicious

- **Confidence:** 80.0%

- **Recommended action:** downgrade\_to\_warn

- **Intent class:** Unknown

- **False-positive risk:** Medium

- **Evidence for:** Manifest installs dependency from a remote tarball URL., Remote dependency source is not included for inspection.

- **Evidence against:** No preinstall, install, or postinstall hook exists., Runtime entrypoint only exports an empty object.
