We all heard about the recent TK Maxxx incident where customer details from 45.7 million payment cards were stolen.
The interesting part in the attack is that the attackers used the US retailer TJX’s Wi-Fi Network (which used WEP) to access the company’s network.
This is an interesting fact since I can imagine the Senior Management playing down the threat from a Wireless Network. “Oh it has WEP, it is OK!”. It is a real threat and just catching or trying to catch the attackers will not make networks more secure. Only continues security reviews of a system will limit breaches.
