LulzSec E-mail Hack Proves We're Lousy at Picking Passwords

We can all learn a lesson from the recent hacks: Even if your password wasn't exposed, change it to something stronger.

Whether you think LulzSec is doing us a favor for exposing our security weaknesses or think the hacker group has gone too far, a very old lesson can be learned here: we need to create stronger passwords. New analysis of the 62,000 logins LulzSec made publicly available reveals, yet again, our seriously weak password habits.

This certainly isn't the first time we've seen how poor some of our passwords are. Last January, one study revealed the most typical passwords used by the 32 million accounts hacked on RockYou.com were "123456" and "password". In December, analysis of 188,279 passwords stolen from Gawker showed those two passwords again as the most commonly used.

The top passwords from the LulzSec dump, according to an analysis by programmer Aviv Ben-Yosef? You guessed it: "123456", followed by "123456789" and in third place, "password".

Other top passwords from the LulzSec sample contained common words like "romance" and mystery," perhaps revealing also some users' desire for thing whole login thing to be less mundane. Other users went the simple route: about 20 percent of the passwords were all numbers.

Despite password best practices-using a mix of uppercase letters, numbers, and special characters-only 2 percent of the LulzSec passwords contained capital letters and a mere 0.85 percent contained special characters.

Ludicrous, right? If you're reading this, you probably don't need to be reminded of how imperative it is to create strong passwords and not use the same login everywhere. You probably do, however, know someone (or many people) who could benefit from you forwarding them some good old password advice, like using password managers to build better passwords (without going crazy) and how adding "789" at the end of "123456" does not make a password more secure.

I would recommend this device for families and small businesses who want one safe place to store all their important digital content and a way to easily share it with friends, family, business partners, or customers.

Brother QL-820NWB Professional Label Printer

It’s easy to set up, it’s compact and quiet when printing and to top if off, the print quality is excellent. This is hands down the best printer I’ve used for printing labels.

Brainstorming, innovation, problem solving, and negotiation have all become much more productive and valuable if people can easily collaborate in real time with minimal friction.

The print quality also does not disappoint, it’s clear, bold, doesn’t smudge and the text is perfectly sized.
