The Password War

Dan Goodin investigates the troubling state of password security:

Newer hardware and modern techniques have … helped to contribute to the rise in password cracking. Now used increasingly for computing, graphics processors allow password-cracking programs to work thousands of times faster than they did just a decade ago on similarly priced PCs that used traditional CPUs alone. A PC running a single AMD Radeon HD7970 GPU, for instance, can try on average an astounding 8.2 billion password combinations each second, depending on the algorithm used to scramble them. Only a decade ago, such speeds were possible only when using pricey supercomputers.

And all those recent, massive password hacks are helping the hackers get even better:

Most importantly, a series of leaks over the past few years containing more than 100 million real-world passwords have provided crackers with important new insights about how people in different walks of life choose passwords on different sites or in different settings. The ever-growing list of leaked passwords allows programmers to write rules that make cracking algorithms faster and more accurate; password attacks have become cut-and-paste exercises that even script kiddies can perform with ease.

The Dish has discussed good password practices before, but the password guidelines appended to article are still worth reviewing.
