For more context about this tool, see https://www.synacktiv.com/publications/cracking-radmin-server-3-passwords.html !
Step 1 : Recover Radmin Server 3 user information from HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\Radmin\v3.0\Server\Parameters\Radmin Security. There might be several registry keys here, one for each user. Export them using the "export" option from the right-click menu of regedit.exe. Save each one in a different file.
Step 2 : Run python3 hash_dumper.py regkey.txt on the key you want to extract data from. You can supply a wordlist directly using --wordlist ./test.txt if you want to bruteforce the password, but this will be very slow.
$ python3 hash_dumper.py regkey.txt

Step 3 : For a faster password bruteforce, paste the username, salt and verifier extracted by the python script into the constants of the radmin3_bf.c file. Compile the file with g++ -o radmin3_bf -O3 radmin3_bf.c -lssl -lcrypto -lpthread.
Step 4 : Run the binary with a wordlist file name as first argument : ./radmin3_bf ./test.txt.
$ ./radmin3_bf test.txt
