You can download this source as mifi-passgen.py. Print "Must specify the 6-digit manufacture date (e.g. Assuming the target device is one of these values, we can quickly build a dictionary to attack the PSK selection with a small Python script and a tool such as coWPAtty or Aircrack-ng: #!/usr/bin/env python Talking amongst my wonderful colleagues at InGuardians, I was able to identify 4 unique manufacture prefixes. 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 where YOU THE READER come in.

Knowing that for a given 6-byte password prefix there are only 100,000 possible passwords, we can get down to exploiting a given MiFi device. If the concept of a manufacture date-stamp is true for the 6-byte prefix, then we have a relatively small search space to find the default MiFi PSK. Instead of 11 numeric values with an effective entropy of approximately 36 bits, the MiFi password only has an effective entropy of less than 17 bits for a given 6-byte prefix.

Sequential Identifier: “ 00891” represents the 5-character sequential identifier code.īased on this assessment, we can determine that the password selection for the MiFi default is weak.

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).

Manufacture Month: “ 11” represents the 2-character month code.

Manufacture Year: “ 09” represents the 2-character year of manufacture.

This password value likely breaks down into four fields: From the photo above, the password on my MiFi device is: 09 The password on the back of the MiFi device also reveals some interesting information. From this we can determine that Verizon has no more than 65,536 unique SSID’s for MiFi devices (potentially less more data is needed to determine if all 16-bits of the BSSID are evenly distributed among devices). The MiFi SSID on my product is “Verizon MiFi DAD1 Secure”, slightly different than that of the MiFi device label (where Kismet reports the addition of ” Secure” to the SSID, and the mixed-case “MiFi”, which is important to us).Īlso, we can see that the “DAD1” in the SSID matches the last two bytes of the AP’s MAC address (or Basic Service Set Identifier – BSSID). Cursory analysis of the beacon information elements don’t reveal anything particularly interesting, though the Kismet screen-shot gives us a point of correlation.
