This is a 🐍 Python project to build a command-line interface application that aims to help a security operations center (SOC) analyst. You are able to enter a host (URL, IP address, email address) and look up security-relevant information. This includes:
- 📧 DMARC and SPF information on domain names (also from URLs and email addresses).
- ✍️ Generic domain registration information.
This is done with (among others) the following Python-modules:
| module | purpose | usage |
|--------------|--------------------------------------------------------|----------------------------------------|
| `rich` | library for writing rich text to the terminal | display and color lookup results |
| `tqdm` | wraps any iterable and displays a smart progress bar | display progress for multiple lookups |
| `requests` | HTTP library | query VirusTotal- and AbuseIPDB-APIs |
| `checkdmarc` | Python module for validating SPF and DMARC DNS records | look up SPF and DMARC records |
