It's great to hear that you are practicing your skills in a safe and controlled environment. Since you have captured the 4-way handshake but did not find a match in the rockyou.txt wordlist, here are a few suggestions on what you can do next:
1. Create a Custom Wordlist: You can create a custom wordlist based on information specific to the target network or the individual whose network you are trying to access. This can include any personal information, common phrases, or passwords related to the target.
2. Use a Different Wordlist: If the rockyou.txt wordlist did not work, you can try using other wordlists that may have a different set of passwords. Some popular wordlists include SecLists, *****Station, or you can create your own based on common patterns.
3. Brute Force Attack: If the wordlist approach does not work, you can resort to a brute force attack. This method involves trying all possible combinations of characters until the correct password is found. However, brute force attacks can be time-consuming and resource-intensive.
4. Dictionary Attack: In addition to the rockyou.txt wordlist, you can try other commonly used wordlists or dictionaries. These lists may contain passwords that are not included in the rockyou.txt file.
5. Hybrid Attack: A hybrid attack combines elements of a dictionary attack and a brute force attack. It can be more effective than a standard brute force attack while being less time-consuming than a pure brute force approach.
Remember, it's essential to have permission before attempting to häçk any network, even if it's just for practice. Unauthorized access to computer networks is îllégâl and unethical. Always stay within legal boundaries and use your skills for positive purposes.
