I run a few blogs - and just now noticed a weird thing.
I checked the wp_users table in the database for few sites and see that there are more users than you can see in the WordPress admin screen.
Particularly, there is a user named 'WordPress' that has a register date of 0000-00-00 00:00:00. It seems to be like that on a few sites.
Our sites have been hacked recently - although probably not through wordpress - but I'm afraid that these extra users were created by hackers so that they are able to log in, etc. And I wanna know if I should delete those extra users.
Or is this normal and these are generated by WordPress and they need to be there?
Thanks for your help!
