Urgent: Server Hacked, Immediate Assistance Needed

Job ID: 38998305

Budget: €30 – €250 EUR

I am in an urgent situation as my server has been compromised. It's an old Debian 7.11 system running apache2, with several Virtual Web Domains, Postfix, PHP & MySQL. A malicious hacker seems to have infiltrated through a security loophole and is now using my server to send out spam, severely damaging my mail server's reputation.

Your primary tasks will be to:
- Analyze net and apache logs to identify the backdoor and trace the malicious code.
- Fix the security hole in the system.
- Remove any remaining malicious code from the server.

I am able to provide you with root access for thorough analysis.

The log files that should be prioritized for the analysis include:
- Apache access and error logs

I have a specific list of virtual web domains hosted on the server, which I can provide separately. Your expertise in server security, log analysis, and experience with Debian systems will be crucial for this project. I need this situation resolved as quickly as possible to prevent further damage.
