Crack the WPA2-TKIP password using aircrack-ng If encryption protocol is CCMP, skip to step 6. TKIP is unsafer than CCMP, and then, much more common that In case of WPA2, it can be either TKIP or CCMP. Check the encryption protocol used in a networkĬheck the value under the “CIPHER” column of airodump-ng screen to identify the encryption protocol. If it is “ENT” (not the most common option, though) this is not covered by this post. For WPA2 networks, it can be “PSK” or “ENT”. Check the authentication option used in a networkĬheck the value under the “AUTH” (Authentication). If it is WPA, you can use tools like coWPAtty. If encryption is WEP, it is the easiest to crack, but this connection algorithm is not that common nowadays for obvious reasons. It can be either “WEP”, “WPA”, “WPA2″ or “WPA3″. Check the security algorithm used in a networkĬheck the value under the “ENC” (Encryption) column of airodump-ng screen to identify the encryption standard or algorithm. The results of networks available will be displayed in a screen like this:Ģ.
Find wireless connections around youįirst, you need to configure your system to be able to monitor networks around you. This section assumes there is a fixed password for the whole network, it means, that network uses PKA authentication protocol. Use these pieces of advice only for educational or research purposes or provide pen-testing services. Remember that cracking a WPA2 may be against the law in most countries. Remember that WPA3 is still vulnerable to Dragonblood attack. Consider migrating to WPA3, when possible.Change router settings default password.
How do I ensure my WPA2 network is secured? You can read more about this on this link. It is not simple to migrate a whole network and the existing components to WPA2. If WPA3 is safer than WPA2, why it is not massively replaced? Some of these vulnerabilities are not present in WPA2′s successor WPA3. It means that WPA2 is vulnerable while performing the key exchange processes. In addition, there are known exploitations of the WPA2 key exchange (or handshake) processes: However, if the implementation of WPA2 uses TKIP, then it is not considered safe. From an encryption point of view and when CCMP encryption protocol is used, WPA2 can be considered safe enough. Is WPA2 safe?Īs of the time this post has been written, no known attacks have been successful against AES/CCMP encryption. Most domestic networks (for example, those having a password printed on a label on the router) use PSK authentication option. Some examples of AAA services are RADIUS (Remote Authentication Dial-In User Service) or TACACS+. PSK is the use of a static fixed password or authentication.ĮNT enables the leveraging of and existing AAA (Authentication, Authorization and Accounting) service to be used for authentication. TKIP encryption protocol was deprecated in 2012 and it is considered unsafe, and so are encryption modes WPA and WPA2-TKIP.ĬCMP is based on encryption algorithm Advanced Encryption Standard (AES).įrom a security point of view, wireless security modes WPA2-CCMP or WPA3 should be used instead.Īuthentication options supported by WPA2: It is based on encryption algorithm Rivest Cipher 4 (RC4), that is considered unsafe. TKIP was designed as a temporary measure to support WPA features without requiring replacement of legacy wireless hardware.

This post explains briefly what is WPA2, its vulnerabilities, how to strengthen a WPA2 network and how to crack it. It has been replaced by more recent WPA3, but as of 2021 WPA2 is still more spread. Wi-Fi Protected Access 2 ( WPA2) is one of the most widespread security standards for wireless networks.
