Bad-PDF is a Python tool that generates malicious PDF files exploiting CVE-2018-4993 to steal NTLMv1/NTLMv2 hashes from Windows machines via Responder listener. It is intended for educational and penetration-testing purposes.
Use cases
- steal ntlm hashes via malicious pdf
- test pdf readers for cve-2018-4993
- capture ntlmv2 hashes with responder
- red team credential harvesting exercise
- demonstrate ntlm credentials theft via pdf
When to choose
- you need to demonstrate or test the CVE-2018-4993 NTLM hash theft vector
- you run authorized penetration tests or security awareness demos on Windows environments
- you already use Responder on Kali Linux for hash capture
When to avoid
- the target Adobe Acrobat is patched (APSB18-09)
- you lack authorization to test the target systems
- you need a general-purpose PDF generation or parsing tool
