LivingSocial, the company that helps users get better deals, announced that they have been hacked. The company notes that the hackers did not gain access to any credit card information. As a precaution, LivingSocial is sending out an e-mail to 50 million of its users informing them of the hack.
LivingSocial hasn't detailed how the hack occurred, but they have said that names, birthdays, e-mail addresses, and encrypted passwords were compromised. Given enough time and the correct tools, those encrypted passwords can be decrypted. Combine the password with the e-mail and the hackers could gain access to other sites.
If you use the same e-mail/password combination on any other sites, you're encouraged to change your passwords right away.
