Perhaps someone who realises that WEP is next to useless anyway. Just because WEP is not enabled, it doesn't mean the site is vulnerable. Traffic may be encrypted with ssh tunnels, or a variety of other methods. see http://interactive.linuxjournal.com/article/8017 (which you need to be a subscriber to read, so heres some quotes: "If you're still relying on WEP alone, you should be nervous: venerable and well-known vulnerabilities in WEP make it simple for eavesdroppers to crack your WEP keys simply by capturing a few hours' worth of WLAN packets and brute-forcing the flawed encryption used by WEP." "In a nutshell, 802.11b's WEP protocol has two fatal flaws. First, cryptographic-implementation flaws make it impossible to achieve encryption key strength effectively higher than 40 bits, even if your gear supports higher key lengths. Second, a weakness in WEP's encryption key derivation implementation makes it possible for an attacker to derive a WEP-protected network's WEP secret key-the encryption key used by all clients on the entire WLAN-after capturing a sufficient number of packets." > > -- > C.
