What to Check When Your Server is Hacked

Having your server hacked is something that no website administrator wants to experience. Once a server is hacked, hackers can steal data, install malware, damage files, and even alter website content. In this case, administrators need to take action quickly to minimize losses. The following are the specific steps to check your server when it is hacked:

1. Check login logs

Hackers typically gain access to servers by logging into administrator accounts or exploiting software vulnerabilities with administrator privileges. Administrators can check login logs to see if there are any unknown IP addresses or abnormal login attempts to determine whether there are unauthorized logins or other anomalies.

2. Check network traffic

Admins can observe network traffic to identify any unknown packets or requests that may have been initiated by hackers.

3. Check system files

Hackers can modify a server's system files to take over the server or hide attack traces. Admins can verify the integrity and correctness of system files to exclude this possibility.

4. Check for malware

Hackers can install malware to steal data, launch attacks, or damage the system. Administrators should check all installed software to identify any abnormal or unknown software.

5. Check website content

Hackers can tamper with website content or post spam information. Administrators should check all website content to ensure there are no irregular or unknown content.

6. Change passwords

If the hacker has administrator account information, administrators should change all related passwords before checking the server to avoid further attacks and losses.
