Automatic Image Publish and Posts Added

Hi,

I am facing strange situation where my website has been hacked recently.

1. Image uploaded and get published automatically without my control.
2. Posts added but not published.

I checked my db table and it shows 16k+ rows.

I checked my media library and there are 12k+ images.

I have temporarily password blocked my website but how should I stop these automatic image and post adding?

Please help me.

Thanks in advance.

Regards,

Kishore
