## Summary

Togoder Security scanned the npm package fastest-levenshtein@1.0.16 on Oct 6, 2026. An AI review of 5 source files produced 2 low severity findings. No malicious behavior, install-time payloads, credential theft or exfiltration were identified.

## Findings

### [low] File System Write

Finding ID: `NPS-F6DAF1E975B1`

File: `bench.js:41`

The benchmark writes a data.json file to the current working directory if it doesn't exist. This is standard for benchmarks to persist test data between runs and is not malicious, but it does modify the file system outside the package scope.

### [low] File System Read

Finding ID: `NPS-4D930707D5CF`

File: `bench.js:44`

Reads data.json from the current working directory. This is expected behavior for a benchmark script.

## Files reviewed

- `bench.js` (safe): This is a legitimate benchmark script comparing Levenshtein distance libraries; it only performs local file I/O for caching test data and contains no malicious patterns.
- `esm/mod.js` (safe): No malicious patterns detected; the code is a standard implementation of the Myers string distance algorithm with no network, filesystem, or process operations.
- `mod.js` (safe): No malicious patterns detected; the code is a standard implementation of the Myers string distance algorithm with no network, filesystem, process execution, or obfuscation concerns.
- `test.js` (safe): No malicious patterns detected
- `test.ts` (safe): Cleared by Jev triage; no further analysis needed
