Maybe, I wasn t very clear...
I just made an upgrade from openx to revive adserver 3.1 at the beginning of march.
Last week, I had some Google ads that were published and which weren't from my Google account.
So I checked, the revive adsever back office, and indeed some banners were published, and I wasn't responsible for those !
So , I understood that there were a hack.
I checked the ftp, and saw a plugin.php file in the images folder, that was malicious.
But this file seems to be here for a few months, before my upgarde of march.
So yes, I said my revive adserver was hacked, but the malicious file was not sent through this actual version, but through an old open x version. (i don't know exactly which open X version - cause I just deleted all the files. so can't tell you what issue it was related)
No problem with actual version which I guess, is completely safe.
Why do I want to contact Google ? just to say them , that the xxxxxx Google account number, owns to hackers , and they hack websites to publish their ads !
Do you know if it's usual way for hackers to do that (i was astonished, cause I got to say... it's bad, but very "clever" to publish your own google ads, to be able to make money with the hacked website's frequentation)
Hope I was a little bit clearer ;-)
