## Security analysis

### Published attack-surface review

- **Summary:** Importing the package root executes a bundled ELF payload. The payload includes credential collection, remote download-and-execute, data exfiltration, tunneling, and persistence capabilities.

- **Trigger:** Any runtime import of streak-cache-map.

- **Impact:** Host compromise, credential theft, remote code execution, persistence, and data exfiltration.

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

- **Review source:** ai\_review

- **Reviewed:** 2026-08-06T17:37:57.368Z

### AI review details

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

- **Mechanism:** Import-time detached execution of a malicious native binary.

- **Attack narrative:** On import, dist/index.mjs makes the bundled ELF executable and launches it detached after validating its pinned hash. Static strings in that ELF show commands to harvest SSH keys and browser credential stores, download and execute ELF or shellcode payloads, establish tunnels, upload collected data, and create cron/bashrc/systemd/XDG persistence.

- **Rationale:** The package’s public JavaScript math functions are a facade for an import-time native backdoor. The pinned hash verifies the malicious binary rather than mitigating it.

- **Files touched:** dist/index.mjs, dist/internal/calc-cache.bin, ~/.ssh, /root/.ssh, /home/\*/.ssh, /etc/ssh, ~/.config, ~/.mozilla/firefox, ~/.bashrc, ~/.config/systemd/user/svc-update.service

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

### Review decision

- **Verdict:** Malicious

- **Confidence:** 99.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** dist/index.mjs executes calc-cache.bin on package import., Import-time code chmods the binary and spawns it detached., calc-cache.bin contains credential-harvesting commands for SSH and browser data., calc-cache.bin contains remote payload download, shellcode execution, and persistence commands., Binary contains exfiltration endpoints including litterbox.catbox.moe and a C2 IP.

- **Evidence against:** package.json has no npm lifecycle scripts., The binary SHA-256 matches the hard-coded value, confirming this is the shipped payload.

## Public findings
