Keyspace List for WPA on Default Routers
#18
(02-11-2017, 03:54 AM)duhblow7 Wrote: ssid = DG1670AXX
preshared key = DG1670A+[0-9A-F][len6]

Example:
SSID = DG1670AB2
PSK = DG1670A919DB2

keyspace = 16^6 = 16,777,216

edit- I cracked a few more of these and I noticed that the last two characters of the PSK are the same as the last two characters of the SSID.

This takes the keyspace down to 16^4 = 65536

It seems like it would be worthwhile to build a list of all possible model numbers and then prepare a .hcmask file.

For example:
DG1670A?H?H?H?HB2
TC8715D?H?H?H?HB2

Note that the DG1670A is Motorola device.  The TC8715D is a Technicolor device.  Both use the same scheme for their default WPA2 password and both are for use with Time Warner.  Both have the last two digits of their default password as the last two digits of their default SSID.

Is this default password scheme being used on several devices that are in use with Time Warner customers?  Maybe.  It seems less likely that two different vendors of modems/routers decided to use the same default password scheme.

This is a quick list of model numbers that I have come up with.  Note that most of these model numbers are Technicolor and just a few are Motorola model numbers.
