I have just received this email from AbeBooks.com:
Hello AbeBooks Customer,
This is an important message from AbeBooks.com.
As part of our routine security monitoring, we have learned that a list of email addresses and passwords were posted online this week.
While the list was not AbeBooks-related, we know that many people reuse their passwords on several websites. We believe your email address and password set was on the list posted online.
Therefore we have taken the precaution of disabling your password on your account. We apologize for any inconvenience this has caused but felt that it was necessary to help protect you and your AbeBooks account.
I don't care so much about my AbeBooks.com account as I barely use it. But, I am very worried to know that my email and password are published online. Although I tried to Google for my email and haven't found anything.
What should I do now? Should I change the passwords in all my 50+ accounts?
