# MAL-2026-7023: Malicious code in dbzy-tools (PyPI)


- **Type:** Malicious package
- **Package:** `dbzy-tools` (PyPI)
- **Published:** 8 Jul 2026

## What is MAL-2026-7023?

MAL-2026-7023 is a malicious package in dbzy-tools, published on 8 Jul 2026. 

### Official description

The package advertises itself as a network debugging tool but its CLI and modules compose a remote-access toolkit. The `dbzy-tools` console entry calls `core.start(config_url)` which fetches JSON from a caller-supplied URL via urllib, base64-decodes the `payload` field, and passes it to `exec()` with no integrity check — arbitrary Python code from an arbitrary URL runs in the invoking user's context. `server.py` implements a paramiko-based SSH server that binds 0.0.0.0:2222, accepts hardcoded default credentials `root`/`password`, and spawns `/bin/bash -i` as an interactive pty for each authenticated session; paramiko is auto-installed via `pip install` at first import. `frpc.py` downloads an frpc reverse-proxy binary from a caller-supplied URL via `curl`, chmods it 0755, writes a config that tunnels a local port to an operator-chosen remote frps server, and launches it — providing a NAT-piercing path back to the SSH shell. The combination of remote-payload exec, listening SSH-to-bash bridge with default creds, and outbound reverse tunnel is a complete backdoor/RAT toolkit packaged under a benign cover.

## What should I do about MAL-2026-7023?
