We had a security breach that affected all Wordpress sites on our dedicated server (CentOS, WHM, Cpanel): all wp_users records on all domains/sites were changed to a single user/pass combination. After many hours of investigations this doesn't seem to be a WP specific issue, rather a server security problem. We need some help checking logs and finding the source of the breach. MANDATORY: you must be able to work via remote access and communicate voice on Skype, so very good English verbal skills are required! We have a lot of things we have already discovered and want to quickly show you. If you want your bid to be considered please include in the bid 2 things: 1. describe your security expertise - senior system admins / security experts needed 2. write the first 2 things you wish to check considering the very short description above

Hello Sir, This is my experience that if one infected file exists on your server then it will infect your server again and again. So I need to check each file and folder manually. Sir,I never use any software or any programming script or any scanner to find out malicious files or script on server. Because they can never give you 100% accuracy. But I will provide you 100% accuracy because I go through whole server manually and check each file and folder manually. I will also check your SQL file because I have found malicious script or suspicious script in SQL file many times. Thanks
