Popular online speed trap locator Trapster has been hacked and is notifying its 10 million users their email and password may have been compromised:
Dear Trapster User:
The Trapster team has recently learned that our website has been the target of a hacking attempt, and it is possible that your email address and password were compromised. We have taken, and continue to take, preventative measures to avoid future incidents but we are recommending that you change your Trapster password. As always, Trapster recommends that you use distinctive passwords for each site you visit, but if you use the same password on Trapster that you use on other services, we recommend that you change your password on those services as well.
For information on how to reset your password or improve the security of your passwords for your Internet usage, please click FAQs.
The Trapster Team
Trapster users should immediately change login credentials, and be alert for other services that may be affected if the same email/password combination is used in multiple places (which this should show you should never do).
Hat tip to Jason Perlow for the tip.
