Currently we have 27 (shown on the #Data column). To break through WEP encryption, we will need numerous data packets that have the same encryption key to exploit the protocols weakness. It automatically generates traffic dump files from every authentication and connection that the router receives. If you type in ls in the terminal, you can see that the kali laptop has now files stored on the machine. The laptop that has airodump-ng up and running should show that the other laptop connected to the network.

Remember when in the beginning we said that you need two laptops? The other one should have Kali with the adapter up and running, and the other one shouldn’t be doing anything at the moment.Ĭonnect the laptop that is inactive into the wifi and sign in – use the WEP Key as the password for the wi-fi (for us it was babdebbabdebbabdebbabdeb23) to sign into the network. The –write command saves the traffic into a pcap file, that we will use to crack into the network. You can change the “testiwep” to be whatever name you wish, it’s the name of the pcap file generated on your computer. Since we only want to find out what’s happening with our own network, we can filter the airodump to only show our router’s traffic with the following command: airodump-ng wlan1mon -bssid D4:6E:0E:FC:AB:E4 -channel X -write testiwep wlan1mon Now lets locate our access point from the local networks using the command: airodump-ng wlan1monįrom the list of machines, find the one that has the SSID that you set for your Access Point. This changes the wlan1 to wlan1mon, you can check with the ifconfig command that the wireless adapter is in monitor mode. Then let’s start the wlan1 in the monitor mode with the command: airmon-ng start wlan1 Open up the terminal and bring up the wlan1 interface with the command: ifconfig wlan1 up You can type anything you want in the WEP Key – as long as it only consists of letters A-F and numbers 1-9.Īfter we have set our WEP key, lets start our attacker laptop and configure it.

We chose as the WEP Key to be babdebbabdebbabdebbabdeb23 as our key – this is the password that you would have to type in order to access the WEP protected Wi-Fi. We chose 128bits for WEP key length – or when talking in a more simple way, it is 26 characters. There needs to be a key length set for the WEP Key. The devices that are connected to your router display.Remember when we set the access point’s security mode to Disabled? Now let’s go to the same settings and change the Security Mode to WEP. Swipe up on the network information panel. How can I know what devices are connected to my router?Įnter your router’s admin password and tap the LOGIN button.

This attack strategy was found by accident when trying to crack the new WPA3 network protocol, which is much more difficult to hack than WPA/WPA2. The big takeaways for tech leaders: Researcher’s behind popular password cracking tool Hashcat found a faster, easier way to crack WPA/WPA2 Wi-Fi network passwords.

Crack WPA2 using what? WPA2 can be cracked do not get me wrong. There are simply too many additional variables. Times could range from 1 second to 100,000 years.

#HOW LONG TO CRACK WEP PASSPHRASE 64 BIT#

The IV count is the important number to watch for since you will need to capture around 50,000 to 200,000 IVs in order to crack a 64 bit WEP key and for a 128 bit key, you will need around 200,000 to 700,000 IVs! Why is WEP so weak? How many IVs does it take to crack WEP?

Weakness: Authentication Messages can be easily forged.

Weakness: The Integrity Check Value (ICV) algorithm is not appropriate.

Weakness: The Initialization Vector (IV) is Too Small.

WEP has been widely criticized for a number of weaknesses. What are two reasons why WEP is considered unreliable? WPA2 is a secure protocol that’s tougher to crack than WEP. Ideally, you’re on the lookout for a router that supports WPA2. As such, it’s worth upgrading to a stronger network protocol to keep people out. If you use WEP on your home network, you’re at risk of people snooping on your connection. Why should you avoid using WEP on the WiFi network?

#HOW LONG TO CRACK WEP PASSPHRASE ANDROID#

The target person won’t be able to find out that a monitoring app has been deployed on their Android phone, secretly monitoring and recording their phone activity. All you need to do is get physical access to the target Android device and make sure it’s connected on the same WIFI network as your device. The only time you can crack the pre-shared key is if it is a dictionary word or relatively short in length. Unlike WEP, where statistical methods can be used to speed up the cracking process, only plain brute force techniques can be used against WPA/WPA2. This is the approach used to crack the WPA/WPA2 pre-shared key.
