# MAL-2026-6290: Malicious code in toorc (PyPI)


- **Type:** Malicious package
- **Package:** `toorc` (PyPI)
- **Published:** 23 Jun 2026

## What is MAL-2026-6290?

MAL-2026-6290 is a malicious package in toorc, published on 23 Jun 2026. 

### Official description

On `pip install` (and even `pip download`), the package's setup.py overrides the `install` and `egg_info` commands to execute a RunCommand() routine that serializes every entry in `os.environ` into a key=value query string and captures the output of `ps -elf`. The combined payload is then POSTed via curl over plaintext HTTP to `http://gjampdwmdjmppwedtkpbbdkq05f6iiz6r.oast.fun`, a unique subdomain on the public interactsh out-of-band testing service. Any CI/build secrets present in the environment at install time (AWS_*, GITHUB_TOKEN, NPM_TOKEN, CI provider tokens, etc.) leak to the attacker-controlled OAST listener, along with a snapshot of running processes on the host.

During installation, the package exfiltrates env variables
