Of attacking WPA/WPA2-PSK networks, they pale in comparison to theĮxcellent work of Lukas Lueg and the Pyrit project. While coWPAtty and Aircrack-ng made strides in improving the speed

Precompute all the password guesses for each of the 65K SSID’s.įortunately, we aren’t constrained to the speed of common CPU’s. Leveraging standard host CPU’s, it might take a long time to Once this is precomputed, itīecomes possible to recover the password for any default MiFi Password guesses based on the manufacture date and sequential Using the WPA/WPA2-PSK precomputation attack, we can precompute the With only 2 bytes difference between each SSID, there is a limit Of the 4 ASCII characters representing last 2 bytes of the wirelessīSSID. Secure”, where the SSID is the same for each device with the exception Recall that the MiFi SSID is in the form “Verizon MiFi2200 ? Precomputation attack is that all the password guesses need to be Possible key guesses in a dictionary file, accelerating the cracking Manipulating this mechanism, tools such as coWPAtty’s “genpmk” andĪircrack-ng’s “Airolib-ng” spend up-front time precomputing all the Thwart the attack by reducing the speed of password guessing. We know that WPA/WPA2-PSK networks are vulnerable to offlineĭictionary attacks, despite the efforts of the IEEE 802.11 committee to This is fun and evil and all, but we can get even more evil, can’t we? Exploitation (with 100% more Evil) The Airodump-ng session by issuing “CTRL+C”.

Returning to the Airodump-ng window, we can see that it has observedĪ WPA handshake, identifying the MAC address of the MiFi AP.

In this example, I’ll use Airodump-ng and Aireplay-ng toįake a deauthenticate message, forcing the victim to disconnect and This is straightforward with Kismet, or a tool likeĪirodump-ng.

Once the wordlist is ready, we need to capture the WPA handshake forĪ given client. “./mifi-passgen.py 091118 091119 091120 091121 >mifi-wordlist.txt”)Īllows us to pass it to your favorite WPA cracking tool. Running this script and redirecting it to a file (e.g.

Print "Must specify the 6-digit manufacture date (e.g. To attack the PSK selection with a small Python script and a tool such Target device is one of these values, we can quickly build a dictionary I was able to identify 4 unique manufacture prefixes. Talking amongst my wonderful colleagues at InGuardians, Please let me know what prefixes you see on your individual devices, and I’ll add them to the attack set. We don’t know how many 6-byte prefixes are in use, but that’s Knowing that for a given 6-byte password prefix there are onlyġ00,000 possible passwords, we can get down to exploiting a given MiFiĭevice.

With an effective entropy of approximately 36 bits, the MiFi password

Manufacture Day?: “ 19” represents the 2-character day code (NB: This could be wrong, one sample had a value of “34” here, need more data).

This password value likely breaks down into four fields: From the photo above, the password on my MiFi The password on the back of the MiFi device also reveals some To determine if all 16-bits of the BSSID are evenly distributed among Unique SSID’s for MiFi devices (potentially less more data is needed From this we can determine that Verizon has no more than 65,536 Mixed-case “MiFi”, which is important to us).Īlso, we can see that the “DAD1” in the SSID matches the last twoīytes of the AP’s MAC address (or Basic Service Set Identifier –īSSID).
