Anyway, if you as you say they are logging in as admin, why is it only happening to the most recent post only? If i were a spammer and I obtained admin access I would spam/alter all the posts and even mass post spam everywhere.

So what shall I do to resolve this?

which logs do you need? or which file?

it does appear like a wordpress problem. I have been having this lately–for the past few weeks. Look here:

this same post mentioned above is injected with spam, no matter how many times i edit the post and remove it it gets back, and comments are turned off too. I thought it was a problem with my host and I was hacked so I changed my host to a new one, same problem is happneing. I’m using 2.3.3 and I’m sure about it.
