AOL confirmed to News4 Tuesday its email system was hacked.
AOL says it's working to resolve an issue of "account spoofing".
Spoofing is when a spammer sends out emails using your email address. The message appears to be from you in order to trick people into opening it.
AOL says it's immediately changing its policy to help mail providers reject spoofed AOL emails.
Twitter is filled with users complaining their AOL accounts were hacked.
Below is AOL's complete company statement:
