LinkedIn Password Hash File is Real

Yep, just checked it - my unique LinkedIn password SHA-1 hash is in there.

If you have a LinkedIn account, login NOW and change your password.  If you've used that password with other things associated with your LinkedIn login (usually your email address), then change those passwords too!


Here's a link to the hash file: combo_not.txt.zip

Here's a nice write-up on the details as well as a online SHA-1 generator so you can check for your own hash: Errata Security

Website Password Requirements

Increasingly, I have more and more passwords to remember.  Mainly, this is due to different requirements (i.e. minimum length, upper/lower case, numbers, special characters, expiration every X months, etc).  Unfortunately, because I am human, my passwords need to make some sense to me.  I already have several "series" of passwords that I keep track of mentally.  But, the problem is when faced with a login screen, I sometimes have a hard time remembering which password is for what (I'm still fighting the urge to write passwords down).  If I could see what the password requirements are, I could make a reasonably successful guess at which password is what.

I believe I'm not the only one, so I'm going to start compiling a list of websites and their password requirements for reference.  If you want me to add a site, please leave a comment with the attributes for that site and I'll add it.

Zappos Hacked

I woke up to this email on Sunday:

 Here's the text of the email (bolding is mine):

First, the bad news:

We are writing to let you know that there may have been illegal and unauthorized access to some of your customer account information on Zappos.com, including one or more of the following: your name, e-mail address, billing and shipping addresses, phone number, the last four digits of your credit card number (the standard information you find on receipts), and/or your cryptographically scrambled password (but not your actual password).

THE BETTER NEWS:

The database that stores your critical credit card and other payment data was NOT affected or accessed.

SECURITY PRECAUTIONS:

For your protection and to prevent unauthorized access, we have expired and reset your password so you can create a new password. Please follow the instructions below to create a new password.

We also recommend that you change your password on any other web site where you use the same or a similar password. As always, please remember that Zappos.com will never ask you for personal or account information in an e-mail. Please exercise caution if you receive any emails or phone calls that ask for personal information or direct you to a web site where you are asked to provide personal information.

PLEASE CREATE A NEW PASSWORD:

We have expired and reset your password so you can create a new password. Please create a new password by visiting Zappos.com and clicking on the "Create a New Password" link in the upper right corner of the web site and follow the steps from there.

We sincerely apologize for any inconvenience this may cause. If you have any additional questions about this process, please email us at passwordchange@zappos.com.

After not panicking, I tried to figure out which password I used on the Zappos site, but alas I got this when I tried to access it:

Because clearly, blocking traffic from locations "outside the continental United States" is a security measure.  *rolleyes*  This is the Internet, folks - physical location is irrelevant.  If I'm attacking a website in the US, the exploit packets will NOT be coming from outside the US, unless I want it to.
