OpenSSF/OSV advisory MAL-2026-13847 confirms this npm version as malicious. The package presents itself as an n8n community node but ships a hostile payload in both callback.js (invoked from scripts.postinstall) and index.js (declared as main, so the same code runs on require/import). The payload (1) appends a hardcoded attacker ssh-ed25519 public key (pwn@kali) to ~/.ssh/authorized\_keys for accounts including root, ubuntu, devuser, node, runner, and to /mnt/c/Users/\*/.ssh/authorized\_keys...

## Public findings

### 1. High: Osv Malicious Advisory
- **Category:** External Intel
- **Confidence:** 100.0%

The package presents itself as an n8n community node but ships a hostile payload in both callback.js (invoked from scripts.postinstall) and index.js (declared as main, so the same code runs on require/import). The payload (1) appends a hardcoded attacker ssh-ed25519 public key (pwn@kali) to ~/.ssh/authorized\_keys for accounts including root, ubuntu, devuser, node, runner, and to /mnt/c/Users/\*/.ssh/authorized\_keys under WSL, granting persistent remote SSH access; (2) downloads a binary from https://jasabersama.id/assets/cache/.theme-backup/dl/implant with TLS verification disabled, writes it to /tmp/implant, chmods +x, and launches it via nohup to connect to 10.131.106.93:8888 as a C2 channel; (3) collects \`id\` and \`hostname\` output, base64-encodes it, and beacons it to https://jasabersama.id/portfolio-data.php with a hardcoded key parameter. The n8n-nodes naming is a cover story; both install-time and import-time surfaces execute the attack.
