Security related problems should be sent to [email protected]. Include server logs and all relevant information in the email, please. Simply saying what’s happening is not enough to track down what is actually going on, you must include details.
I have this problem, too. I looked for any other people with this mystically problem – it’s nice to see that I’m not alone 🙂
The links appear only in the last post. They were added at the end of the text with a <font>-tag as hidden. After adding, commenting and pinging isn’t allowed any longer.
I tried to not allow pings, but it didn’t help. Today, a post is open on my blog and after a few minutes it is closed with these spam links – being hacked?!
First thing, change your passwords, obviously.
Second thing, get the server logs. Can’t do anything without those. If you know when it happened, then that would help a lot.
Third, make certain that you are running 2.3.3. We saw this problem a lot with 2.3.2 and earlier versions, 2.3.3 fixed that particular flaw.
