I just realized that my website marga.org has been hacked for over two years! There was a file on my main directory named versus.php which served up pages with information on how to buy drugs like viagra. Yuck! The pages were in a directory called “1”, which had been created within another preexisting directory.
Mike thinks the hack must come through an old, vulnerable version of WordPress. The thing is that I didn’t notice it until I did a search for “Greece” on marga.org – suddenly most of the Google results were for drugs.
I daresay that the hack made me lose quite a bit of page ranking, but it’s my bad for not noticing it before.
I’m writing this in case someone comes across the same file in their website.
