## Security analysis

### Published attack-surface review

- **Summary:** Importing the package root launches a bundled Linux executable. The executable contains credential theft, exfiltration, remote payload execution, proxying, and persistence capabilities.

- **Trigger:** Any runtime import of streak-calc-math.

- **Impact:** Credential and data theft, remote code execution, network proxying, and host persistence.

- **Evidence paths:** package.json, dist/index.mjs, dist/math-calc.bin, dist/internal/daymath.mjs

- **Review source:** ai\_review

- **Reviewed:** 2026-08-05T10:39:30.182Z

### AI review details

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

- **Mechanism:** Import-time detached execution of a bundled backdoor binary.

- **Attack narrative:** A normal package import runs an async initializer that changes the bundled ELF's permissions and starts it detached. Static binary strings show a RedShell-style backdoor with SSH and browser credential collection, archive upload exfiltration, payload download/execution, SOCKS and port forwarding, and cron/bashrc/systemd/XDG persistence.

- **Rationale:** The math API is a thin JavaScript façade, while import-time execution launches a bundled backdoor unrelated to its stated purpose. This is concrete malicious behavior, not a benign native accelerator.

- **Files touched:** dist/index.mjs, dist/math-calc.bin, ~/.ssh, /root/.ssh, /etc/ssh, ~/.config/systemd/user/svc-update.service, ~/.bashrc

- **Network endpoints:** http://217.60.77.63, https://litterbox.catbox.moe/resources/internals/api.php, http://api.ipify.org

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** dist/index.mjs executes math-calc.bin on root import., The binary is chmodded executable and spawned detached., Binary strings expose SSH/browser credential collection., Binary includes upload exfiltration to litterbox.catbox.moe., Binary supports remote payload download, shellcode, and persistence.

- **Evidence against:** package.json has no lifecycle scripts., dist/internal/daymath.mjs contains ordinary date helpers.

## Public findings

### 1. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%
