Many worms now have what is known as a payload.В Payload is translated as the вЂњpayloadвЂќ and in this case an attachment that the worm brings with it.В The worm can, for example, carry ransomwareВ , viruses or other malware, which then cause damage to the infected systems.В These can then, for example, delete files on the PC or encrypt files in the event of a blackmail attack.В A computer worm can also install a back door that can later be exploited by other malware programs.В This vulnerability gives the wormвЂ™s author control over the infected computer.

In order to spread, computer worms use vulnerabilities in networks.В The worm is looking for a back door to penetrate the network unnoticed.В To get computer worms into circulation for the first time, hackers often send phishing e-mailsor instant messages with malicious attachments.В Cyber вЂ‹вЂ‹criminals try to camouflage the worm so that the recipient is willing to run the program.В For this purpose, for example, double file extensions are used and / or a data name that looks harmless or urgent, such as вЂњinvoiceвЂќ.В When the user opens the attachment or link, they will immediately download the malware (computer worm) into the system or be directed to a dangerous website.В In this way, the worm finds its way into the userвЂ™s system without them noticing.В Once executed, the worm seeks a way to replicate and penetrate other systems.В One way of doing this, for example, is for the worm to send an email to all contacts on the infected computer, which contains replicas of the worm.

The term вЂњcomputer wormвЂќ was first used in 1975 in the novel вЂњThe Shockwave RiderвЂќ by John Brunner.В In this novel, the protagonist of the story creates a worm that collects data.В In the early days of computer science, worms were designed to exploit a systemвЂ™s vulnerabilities.В Instead of seriously damaging the infected computers, they just kept multiplying in the background.В Today, however, the purpose of computer worms has changed.В Today, attackers often use them to gain full access to their victimsвЂ™ computers.Д¬omputers connected to a network are susceptible to various forms of malware, including computer worms.В A computer worm is malware that reproduces itself and spreads over network connections.В The computer worm does not usually infect computer files, but rather infects another computer on the network.В This is done by the worm replicating itself.В The worm passes this ability on to its replica, which allows it to infect other systems in the same way.В The difference between computer worms and viruses can also be found here.В Computer worms are stand-alone programs that replicate themselves and run in the background, while viruses require a host file to infect.
