WiFi keygen tool for BT Home Hubs released |
A security researcher claims to have found a significant weakness in the wireless encryption of a BT Home Hub DSL home gateway made by Thomson.
Exploiting the weakness could enable someone to connect to a victim's Wi-Fi router for malicious purposes such as snooping on their internet traffic or hacking other machines using the same network, according to GNUCitizen, a group of blogging security researchers.
BT's Home Hub ships with default encryption keys to encrypt wireless network traffic using either WEP (Wired Equivalent Privacy) or WPA (Wi-Fi Protected Access).
Router manufacturers use an algorithm to generate those WEP and WPA default keys, wrote Adrian Pastor, one of the GNUCitizen's researchers, on their blog. But the algorithm is predictable and only creates a limited number of easily-guessed keys, Pastor wrote.
