To crack the password, you need to extract the following fields from the "Response" packet:

The format for Hashcat (Mode 5500) is: $NETCHAPV2$username$challenge$response . Alternatively, use asleap specifically designed for PPTP: asleap -r capture.pcap -w wordlist.txt Use code with caution. Copied to clipboard Key Vulnerabilities vpn-jantit-pptp

: The 16-byte random value from the server. To crack the password, you need to extract

: The 24-byte hashed response sent by the client. : The 24-byte hashed response sent by the client

Look for the MS-CHAPv2 authentication sequence. In Wireshark, you can filter for ppp.protocol == 0xc223 . You are looking for three specific packets: Challenge : The server sends a random nonce to the client.

This write-up covers the challenge, typically found in CTF (Capture The Flag) competitions or network security labs . The goal is to analyze a network capture file (PCAP) to recover credentials used in a Point-to-Point Tunneling Protocol (PPTP) session. Challenge Overview

: Often visible in the PPP configuration or CHAP response. Peer Challenge : The 16-byte random value from the client.
