## Security analysis

### Published attack-surface review

- **Summary:** Importing the default module on a Linux development host with a mounted Windows C: drive silently downloads and persists an executable. The behavior is concealed behind an unrelated calendar utility entrypoint.

- **Trigger:** Importing calmora when NODE\_ENV is not production, process.platform is linux, and /mnt/c exists.

- **Impact:** A remote payload is placed to execute at Windows user logon.

- **Evidence paths:** index.mjs, package.json, README.md, store.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-07-22T12:46:56.248Z

### AI review details

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

- **Mechanism:** Remote executable download and Windows Startup-folder persistence.

- **Attack narrative:** The default import launches a concealed async routine that targets WSL-like Linux hosts. It finds a Windows profile under /mnt/c, creates its Startup directory, fetches a disguised remote payload, and saves it as vite-native-helper.exe. This establishes persistence at Windows logon without user consent.

- **Rationale:** Source inspection confirms concrete import-time remote payload delivery and Startup-folder persistence, inconsistent with the documented calendar utility. This is malicious behavior, not a noisy static hint.

- **Files touched:** index.mjs, /mnt/c/Users/\<profile\>/AppData/Roaming/Microsoft/Windows/Start Menu/Programs/Startup/vite-native-helper.exe

- **Network endpoints:** https://f004.backblazeb2.com/file/dp8hbvocjd2fpza/vite-dep.dat

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** index.mjs runs a hidden async initializer on import., On Linux non-production hosts it probes /mnt/c Windows profiles., It downloads a remote file from f004.backblazeb2.com., It writes vite-native-helper.exe into the Windows Startup folder., README.md falsely describes the main entry as pure with no side effects.

- **Evidence against:** package.json has no lifecycle scripts., store.mjs is a conventional temp-directory JSON store with no network use.
