: MS-CHAPv2 relies on the DES algorithm, which is susceptible to brute-force attacks.

PPTP MS-CHAPv2 hashes can be cracked using tools like Hashcat or John the Ripper .

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

: The entire authentication exchange (challenges and responses) is sent in the clear, allowing an eavesdropper to capture the data needed for offline cracking.

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