Crack bt home hub wep key

Adrian Pastor, a security researcher who contributes to the GNUCitizen site, claimed he had been able to build a program that acts like a "rainbow table", or list of possible keys, to discover default BT Home Hub WEP encryption keys. Pastor said his research was made possible by the work of independent security researcher Kevin Devine, who last September published a strategy to crack WEP algorithms by debugging router set-up wizards. Pastor applied this research to BT Home Hub routers and found that, by systematically trying all the logical options — so-called "brute-forcing" — he could derive the unique code of each hub or SSID and the encryption key.

Pastor claimed he tested three different BT Home Hubs and that "the attack seems to work fine". BT Home Hub routers are made by Thompson. BT admitted that there was a problem with the routers but said it didn't believe that any customers had been affected.

BT also recommended that customers change the default wireless key and the encryption type from WEP to WPA, but added that customers should change the administrator login password of the Hub Manager and leave the Hub switched on at all times, to receive firmware updates.

Developers are in short supply. Here are the skills and programming languages employers need. But the algorithm is predictable and only creates a limited number of easily-guessed keys, Pastor wrote. Pastor wrote that the information was passed to GNUCitizen by Kevin Devine, who has previously done research into wireless security.

Using a software tool built by Devine in addition to information already known about the router, it's possible to come up with 80 possible default encryption keys for WEP, Pastor wrote.

Devine created another software tool to try each of those keys on the router until the valid one is found. The researchers, however, are not publishing the software tools used in the attack.
