Yahoo rankings dropped after site hacked

[paul3vanz]

Hello,

Recently our site got hacked and a rogue file was placed (trapdoor.php) on the server. Consequently, this page got indexed thousands of times with random key words. This has caused our number of visitors from Yahoo to drop significantly.

I have used Site Explorer to delete this URL from the listings, I have also secured the site from future attacks and deleted the file itself.

Is there anything else I need to do to get our Yahoo ranking back as it was? We do not carry out any black hat techniques to boost our rankings.

Also, do you know what the point of this file was? I don't understand how the hacker would benefit from this unless they were a competitor?

Thank you in advance for any help.

Kind regards,

Paul

I didn't look at the file becuase it might have a payload. Regardless, they could have planted a script to control content on your pages, to facilitate cloaking, take over the entire server, compromise your email, any number of things.

The important thing is that your site is secured and the next issue to deal with is your rankings. This might be a matter of time, give it one month to two months so that over the course of an update that information can be flushed out and the original rankings return. In the meantime acquire high quality links for Yahoo to follow into your site so they know it's still there and attracting links.
