New WiFi Attack Cracks WPA–Again

A pair of Japanese researchers have developed an improvement on an existing technique for attacking wireless LAN traffic that enables them to intercept and decrypt encrypted packets in about a minute, significantly lowering the barrier to entry for attackers looking to listen in on supposedly private connections.

Trust has long been a favorite target of malicious individuals. Most people would say that proper management of trust is one of the primary cornerstones of information security. Trust is a relative term and all trust relationships should be examined with a very critical eye. Ken Thompson’s seminal paper “Reflections on Trusting Trust”, which won a Turing Award, addresses in detail why we can never be fully sure of the trust relationships in our development environment.

The credit crunch means we’re all increasingly aware of bank charges, interest rates, and how we can save a few extra pennies. Financial advisors have written pages on how transferring an existing credit card balance to another card issuer could save you money, and most people are shopping around for the best offers.
