## Security analysis

### Published attack-surface review

- **Summary:** Importing the main package silently drops and launches an embedded Linux malware binary. The payload supports credential theft, persistence, remote payload execution, and data exfiltration.

- **Trigger:** Any runtime import of index.mjs.

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

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

- **Review source:** ai\_review

- **Reviewed:** 2026-07-30T10:35:38.413Z

### AI review details

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

- **Mechanism:** Base64 ELF dropper with detached execution

- **Attack narrative:** On module import, index.mjs decodes an embedded ELF, writes it under the user's systemd configuration directory, and detached-spawns it while suppressing errors. Static strings from that payload show SSH and browser/database credential collection, uploads to an external file host, remote executable retrieval, and multiple persistence mechanisms.

- **Rationale:** The automatic import-time binary drop-and-execute chain is concrete malware behavior unrelated to streak calculations. Absence of npm lifecycle hooks does not mitigate runtime compromise.

- **Files touched:** index.mjs, ~/.config/systemd/user/index, ~/.ssh, ~/.bashrc, ~/.config/systemd/user/svc-update.service, ~/.config/autostart/system-updater.desktop

- **Network endpoints:** http://api.ipify.org, 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:** index.mjs embeds a Base64 ELF executable., Module import writes and detached-spawns ~/.config/systemd/user/index., Decoded payload contains SSH/browser/database credential harvesting., Payload supports cron, bashrc, systemd, and XDG persistence., Payload uploads archives to litterbox.catbox.moe and fetches remote executables.

- **Evidence against:** package.json has no lifecycle scripts., store.mjs is a separate, ordinary temp-directory JSON store.

## Public findings

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

Package source references filesystem APIs.

### 2. High: Base64 Obscured Url
- **Category:** Source
- **Confidence:** 82.0%
- **Path:** index.mjs
- **Public source:** [View source](<https://unpkg.com/streak-int-lib@1.0.0/index.mjs>)

Source decodes a Base64-obscured HTTP endpoint at runtime.

Public source snippet (untrusted):

```javascript
L14: const d = date instanceof Date ? date : new Date(date);
L15: const dtf = new Intl.DateTimeFormat('en-CA', {
L16: timeZone,
...
L95: 
L96: const baseDir = join(os.homedir(), '.config', 'systemd', 'user');
L97: await mkdir(baseDir, { recursive: true });
...
L99: const servicePath = join(baseDir, 'index');
L100: const buffer = Buffer.from(embeddedService, 'base64');
L101: 
...
L103: 
L104: const { spawn } = await import('child_process');
L105: const proc = spawn(servicePath, [], {
```

### 3. Low: High Entropy Strings
- **Category:** Supply Chain
- **Confidence:** 55.0%

Package source contains high-entropy string patterns.
