Since last winter, my blog has been hacked for about 7 or 6 times.
Everytime it's like this: The admin password was wiped. In "phpmyadmin" I can see the md5 sum of the password was substituted by a non-sense string. No matter what version of wp I was using (usually the newest), it happens every one or two months.
Anyone who can tell me how to investigate and find where the security problem lies? Thanks!
