Extracting Radmin creds from PCAP/NG - GigaNoob™ - 05-17-2024
Based on the work done by synacktiv, philsmd, and others (and with the radmin3_to_hashcat.pl in mind) I've built an updated "radmin3_to_hashcat.py" that works again with Radmin v3.5. I'm now moving to working on extracting the necessary identifiers from network traces (in pcapng format)... My progress has been basically halted with the verifier (hashh).
So far, I've managed to identify and pull everything out of the trace properly:
Username (type 16): 0x2000 (not 0x1000 like in the registry)
Modulus (type 48): 0x3000
Generator (type 64): 0x4000
Salt (type 80): 0x5000
Verifier (type 96): 0x6000
However, the packet stream contains 2 verifiers (128 bytes a piece). I'm sure I'm missing some crucial piece of the puzzle here, but neither of them work with my test credentials.

Note that the verifiers are different on every capture, while the salt and everything else remains static/intact. If this means I have to crack open the .exe and start reversing, it basically means I'm done here and now. Unless of course anyone has an idea of what's going on that can help me finish this thing.
