When you encounter the error message "Failed to crack handshake: wordlist-probable.txt did not contain password," it simply means that the specific text file used for the attack did not include the correct passphrase for the network you targeted. This is a common hurdle in WPA/WPA2 security testing. Why It Failed
Dictionary Limitation: Tools like wifite or aircrack-ng use a "dictionary attack," which is essentially a guessing game. If the password isn't in your .txt file, the tool will never find it.
Default Wordlists: Many tools come with a small, default list like wordlist-probable.txt that only contains common or weak passwords.
Password Complexity: If the target password is long, random, or uses special characters, it is unlikely to be in a basic wordlist. How to Fix It

This report analyzes the common failure state where tools like
capture a WPA/WPA2 handshake but fail to crack it because the password is not in the default wordlist-probable.txt iT 邦幫忙 Handshake Cracking Analysis Report 1. Error Identification The message
"Failed to crack handshake: wordlist-probable.txt did not contain password" occurs when the cracking tool (typically aircrack-ng running behind
) completes its scan of the specified wordlist without finding a match for the WPA MIC (Message Integrity Code). ACM Digital Library 2. Primary Failure Causes Dictionary Limitation : The default wordlist-probable.txt possible characters used
in Kali Linux is relatively small (roughly 4,800 common passwords). If the target network uses a complex or non-standard password, this list will lack the required entry. Incomplete Handshake Capture : Sometimes the captured
file is missing one or more of the 4-way handshake packets. While the tool may detect a "handshake," an incomplete exchange (e.g., missing the EAPOL M2 or M3 frames) makes the password unrecoverable. WPA3/Management Frame Protection : If the target uses WPA3 or has Protected Management Frames (PMF)
enabled, traditional deauthentication attacks to force a handshake may fail, or the handshake itself may be protected against offline dictionary attacks. 3. Recommended Solutions
To resolve this failure, security professionals typically follow these escalation steps:
probable.txt is usually UTF-8. If the WiFi password contains non-ASCII characters (e.g., café123), the wordlist entry cafe123 (without accent) will NOT match, even though visually similar. trying all possible combinations. However
Use a Larger or More Comprehensive Wordlist: Consider using larger and more comprehensive wordlists that include a wider range of possible passwords. Examples include lists like rockyou.txt or custom-generated lists based on the target's possible interests.
Brute Force: If the password is not in any practical wordlist, you might need to resort to brute force attacks, trying all possible combinations. However, this can be extremely time-consuming and computationally intensive.
Generate a Custom Wordlist: If you have information about the password (like its length, possible characters used, etc.), you could generate a custom wordlist. Tools like crunch or John the Ripper can help.
Use Mask Attacks or Combination of Techniques: Mask attacks (specifying character sets and lengths) can be effective. Also, combining your wordlist attack with rule-based mutations can expand the potential guesses.
