"Car Lust is, very simply, where interesting cars meet irrational emotion. It's a deeply personal exploration of the hidden gems of the automotive world; a twisted look into a car nut's mind; and a quirky look at the broader automotive universe - a broader universe that lies beneath the new, the flashy, and the trendy represented in the car magazines."

Amazon has a computer bug security problem. Both Amazon itself and its websites are vulnerable to different kind of attacks. This allows hackers to do phishing attacks to Amazon users.
When a user is redirected from amazon to another site, amazon will check a variable named "token". Every redirected website will be given one token. This idea is OK. However, all URLs related to the redirected website use the same token. This means if the authenticated site itself has Open Redirect vulnerabilities. Then victims can be redirected to any site from Amazon.
The program code flaw can be attacked without user login. Tests were performed on Microsoft IE (9 9.0.8112.16421) of Windows 7, Mozilla Firefox (37.0.2) & Google Chromium 42.0.2311 (64-bit) of Ubuntu (14.04.2)，Apple Safari 6.1.6 of Mac OS X v10.9 Mavericks.
