We must keep in mind that the WPA / WPA2 / WPA3 protocols require a minimum length of 8 characters, so we must take this into account when choosing the password. Of course, the bigger the key, the harder it is to guess. If a user has set a Wi-Fi password that is easy to remember, using two well-known combined words, such as “android” and “Samsung”, it is very likely that these dictionary attacks will be successful (password word : androidsamsung) and can easily infiltrate the wireless network.
Logically, if the user chooses an alphanumeric password that does not contain words, then the brute force attack is the one to perform, as dictionaries do not include this type of key. It is always recommended, if we are going to combine words that we know, to use upper and lower Buy Email Database case letters, as well as symbols in the middle, such as a period or an underscore, as this will make combinations of the different words possible. much more, so we will delay a potential attacker to find our password, something necessary.
Brute force against insecure encryption Without a doubt, the most commonly used option by hackers or any attacker who wants to access a Wi-Fi network is brute force. Note that it varies depending on the type of encryption we use. For example, WEP ciphers can even be cracked within minutes, this type of encryption uses a very weak system that can be broken quickly regardless of whether or not there are connected clients. In the case of WPA / WPA2 keys, the most important thing is to pull the handshake and attack it to get the password in the clear .
