Last night a user in Amsterdam (Audit Trail plugin) managed to log in as the admin and alter the most recent post. All they did was insert a lot of "6" characters inside a font tag with a style that was supposed to hide all the sixes, but didn't.
I had what I thought was a moderately secure password 8 characters long, only one properly spelled word in it, and one non-alphanumeric character.
I'm not really asking for help, just posting in case it happens to others, leaving a trail for reference. I'm keeping an eye on it. Had been hacked twice in the last month with 2.3.1 so I relented and upgraded. learned my lesson! Here's the list and version of plugins I had installed when 2.3.3. post was altered. I went and got the latest versions when I went to 2.3.3.
