Linux Viruses

Definition of Linux Viruses

More than you think

Linux viruses are malicious programs designed to compromise Linux computers in order to access personal information or damage hardware running them. Linux is an increasingly popular operating system among servers, supercomputers, and other devices because of its cost-free accessibility to users and open-source nature – yet many misconceptions still abound about its security despite this perception.


Linux boasts more advanced security measures than comparable operating systems; yet, it remains vulnerable to infection. Due to the unique characteristics of its design compared with Windows or macOS, many mistakenly believe Linux to be immune from virus infection.

Linux viruses’ functionality includes their various harmful behaviors on infected systems; just like any computer virus, these infections aim to do damage and can quickly escalate infectivity of systems they penetrate. Linux bugs typically exhibit characteristics such as:

  • Self-Replication
  • Modifying Files
  • Gathering Personal Data
  • Denial-of-Service (DoS) Attacks
  • Spreading junk
  • Alteration of System Settings
  • Ransomware


Linux viruses refers to those which infiltrate and attack Linux operating systems. While not entirely immune from virus attack, Linux does have less chance than its competing operating systems - such as Windows or macOS - of becoming infected due to being created specifically to resist such software and infections. This makes sense considering Linux was designed this way from its conception onward.

Why would anyone create a virus specifically targeted against Linux?

One potential explanation could lie within its increasing popularity: as more organizations and individuals turn to it as their OS of choice, more victims could potentially fall under its orbit – providing hackers with opportunities to compromise critical infrastructure or gain private data.

What were the initial Linux viruses

In 1997, Dr. Mark A. Ludwig released the "Bliss-1" virus as the inaugural Linux OS-specific virus known to science. Dr. Ludwig created it to highlight security flaws within Linux OSes. This virus was designed to be harmless, with limited powers. Instead, its purpose was as an illustration and caution to Linux users that their security should remain vigilant.

More viruses and malware have been designed specifically to target Linux computers
