Is There a Way to Tell If a Linux Server Is Compromised

One of the major indicators of a compromised Linux Server is that it sends out a huge amount of spam from the hosting account. This guide shows how you can recover from the situation and prevent future attacks against your Linux Server. 

Where The Spam Comes From?

Below are the prime causes of the distribution of spam from your hosting account.

  • Malware from a or home computer or an infected work sends spam through your email account.
  • Your web site is negotiated by a hacker. They are executing automated scripts to send out spam from the hosting account.

The commonest form of attack is through the web site. A hacker scans the website to look for pitfalls in the content management system. If the website software isn’t secured or updated regularly then they can easily gain unauthorized access to it. 

Once they do this, they can obtain access to the system and upload endless scripts to the account. These scripts will distribute spam without getting any hint.

Ways To Restore The Services Of Your Hosting Account

To restore the services of the hosting account, two scenarios need to be considered.

  • If you don’t operate a website and the spam is sent via a negotiated mailbox then the following tasks should be performed: 
  • Reset the cPanel account password
  • Reset the mailbox password
  • Get you a support ticket on an alternative email address. It will have a new mailbox password to update the email software with fresh details. 
  • If you operate a website then the entire account has to be terminated and re-formed from scratch. Once the website gets compromised, there is no way to know what files have altered and where does the spam emanate from. Website termination deactivates the infected website and the spam generation stops.

If the spam is being distributed from within your web site then we will:

  • Reset the cPanel account password
  • Terminate and again make your account
  • Get a support ticket to an alternative email address. This ticket contains the new cPanel password to update the software with the new details.

On getting the new login credentials, contact the web developer to upload the web site using a clean backup. This is the backup that got formed before hacking the website. 

How to prevent your system from getting compromised again?

Secure and maintain the content management system regularly. Talk to the web developer about the right approach with a particular website.  Perform continuous scans on the local system and website to avoid the presence of any viruses or malware. 

The modern antivirus software such as ESET Smart Security, Kaspersky Anti-Virus, and Norton Antivirus are great. It will help scan and delete any malware that may be present on the computer. They also help in the prevention of DDoS events and infections. 

Regularly monitor your server to ensure that it is not operated in an unsafe environment like a public Wi-Fi. Work with a reputed ISP service provider to assign a static IP address configured to the server’s firewall. This ensures that no one else can access it from an untrusted environment.


Despite a rise in hacking instances, several website owners are slightly casual in regards to implementing security measures. Follow the guidelines to keep your dedicated or VPS server in the best health.
