Bad-Pdf - Steal Net-NTLM Hash using Bad-PDF

项目说明

Bad-Pdf

Bad-PDF create malicious PDF file to steal NTLM(NTLMv1/NTLMv2) Hashes from windows machines, it utilize disclosed by checkpoint team to create the malicious PDF file. Bad-Pdf reads the NTLM hashes using Responder listener.

~~This method work on all PDF readers(Any )~~ most of the EDR/Endpoint solution fail to detect this attack.

~~* patches are not a for this ~~

Adobe patch:

* Microsoft issued an optional security enhancement [0] late last year that provides customers with the ability to disable NTLM SSO authentication as a method for public resources.

* Disable external SMB access in firewall to prevent NTLM hash leak to internet
