[Cryptonomicon] The 802.11b DoS Attack and Portable Viruses tracta d'explicar l'abast real de la vulnerabilitat descoberta al protocol 802.11 i que pot ser utilitzada per atacs de denegació de servei (veure l'article publicat ahir)
By now you will probably have heard about the alert from AuCert that describes a Denial of Service (DoS) attack on Wi-Fi networks. You might also have heard it's an attack against the protocol and not against a specific implementation. This means it's likely to be difficult to defend yourself simply by applying a patch from your vendor. Addressing this issue will likely require a fair amount of work from ALL the vendors involved; the type of intense collaboration that resulted in 802.11i and it's less beefy, but easier to implement cousin Wi-Fi Protected Access (WPA). We hope you've also heard that an attacker will only be able to attack networks they can reach directly, over the air; an attacker must have control of a machine on or near the wireless network. They can't simply logon to a machine in London and send a specially crafted packet across the Internet to a wireless network in Washington DC; the attack doesn't work that way.
