What is a computer worm?
A computer worm is a type of malware that self-replicates and spreads to other computers. It takes advantage of vulnerabilities in networking protocols to infect systems. Worms are different from viruses because they do not need an existing program to attach to. Instead, they use a network to send copies of themselves to other computer terminals and then to other networks. Worms can cause harm by consuming system resources and network bandwidth. They can remain active on infected systems and continue to spread to as many vulnerable systems as possible.

How do computer worms work?
Computer worms are malicious programs that propagate by exploiting vulnerabilities in networking protocols. One such vulnerable protocol is the File Transfer Protocol (FTP). Once a system becomes infected with a worm, the worm follows its prime directive to remain active and spread to other vulnerable systems.
Worms have clever ways of disguising themselves as nonthreatening resources, such as files or links. They entice unsuspecting users to click on or download them, thereby facilitating their transmission to new targets. These seemingly innocent appearances allow worms to gain access to newly infected systems, continuing their destructive path.
What makes worms particularly dangerous are the malicious payloads they carry. These payloads can take different forms, with some designed to delete files or corrupt data, while others grant hackers remote control over infected computers. The repercussions of such malicious actions can be devastating for individuals and organizations alike.
Notable examples of computer worms include the infamous WannaCry ransomware worm, which spread globally in 2017, infecting hundreds of thousands of computers. Another prominent worm is Stuxnet, a highly sophisticated worm that targeted industrial control systems, specifically those used in Iran’s nuclear program. Stuxnet is widely believed to have been created by a nation-state for covert cyber warfare.
Understanding how computer worms operate is crucial for implementing effective defense strategies against them. By staying informed about evolving threats and adopting robust security measures, individuals and organizations can protect themselves from the destructive impact of computer worms.

Each type of worm utilizes specific mechanisms to spread and infect systems, exploiting different vulnerabilities in the process.
What’s the difference between a worm and a virus?
Computer worms and viruses are both self-replicating programs, but they have different characteristics and behaviors. According to the “Security of the Internet” report, computer worms are self-replicating programs that spread without human intervention after they are activated. On the other hand, computer viruses also replicate themselves, but they usually require some action on the part of the user to inadvertently spread to other programs or systems.
While worms focus on spreading and replicating themselves, viruses often target and corrupt files on specific computers. This key difference in behavior determines how worms and viruses affect computer systems and networks. Worms can rapidly infiltrate and overrun systems, exploiting vulnerabilities in networking protocols to spread autonomously. Viruses, on the other hand, typically require a user to execute an infected file or program, enabling them to modify files and propagate through manual actions.
“Computer worms are self-replicating programs that spread without human intervention after they are started.”
This distinction highlights the contrasting strategies employed by worms and viruses. Worms are designed to propagate quickly and efficiently, leveraging networking protocols to infect as many vulnerable systems as possible. In contrast, viruses aim to infiltrate and manipulate specific files and programs, often leading to data corruption or system instability.
Understanding the differences between worms and viruses is crucial for effective cybersecurity measures. By recognizing their unique characteristics, organizations can implement appropriate defenses to mitigate the risks associated with each type of malware.
