Google spent a lot of time yesterday talking up WebGL, but UK security firm Context seems to think users should disable the feature because it poses a serious security threat, and the US Computer Emergency Readiness Team (CERT) is encouraging people to heed that advice. According to Context, a malicious site could pass code directly to a computer's GPU and trigger a denial of service attack or simply crash the machine. Ne'er-do-wells could also use WebGL and the Canvas element to pull image data from another domain, which could then be used as part of a more elaborate attack. Khronos, the group that organizes the standard, responded by pointing out that there is an extension available to graphics card manufacturers that can detect and protect against DoS attacks, but it did little to satisfy Context -- the firm argues that inherent flaws in the design of WebGL make it very difficult to secure.
Now, we're far from experts on the intricacies of low-level hardware security but, for the moment at least, there seems to be little reason for the average user to panic. There's even a good chance that you're not vulnerable at all since WebGL won't run on many Intel and ATI graphics chips (you can check by

The recent pilfering of PlayStation Network passwords and personal info shows that having a strong passcode doesn't always guarantee your online safety. However, key-pattern analysis (KPA) software from researchers at American University of Beirut may be able to keep our logins secure even if they're stolen. You create a unique profile by entering your password a few times while the code tracks the speed and timing of your keystrokes. The software then associates that data to your password as another means of authentication. Henceforth, should the magic word be entered in a different typing tempo, access is denied. We saw a similar solution last year, but that system was meant to prevent multiple users from accessing subscription databases with a single account. This KPA software allows multiple profiles per password so that your significant other can still read all your email -- assuming you and your mate reside in the trust tree, of course.
