Python Simple UDP Connect using socket with AES GCM decryption to get flag
Created for one of TryHackMe Room.
Please check out the full script here
The script will connect to UDP Server with a specific given port.
Then will need you to send 4 message to UDP server to get response and instruction
- " hello "
- " ready "
- " final " --- First " final " will get the 256 checksum of flag
- " final " --- Second " final " will get the tag
Then it will decrypt the AES GCM and check the 256 checksum against the one given by UDP Server.
