The type of malware that replicates itself to spread rapidly across a computer network is called a worm. Unlike viruses, worms do not need to infect specific files to replicate; instead, they copy themselves and transmit themselves from one system to another over the network, which can cause an exponential increase in traffic and potential damage to affected systems.
Answer is D - key piece of information is the rapid pace it can replicate, page 33 sg
● Worms: A worm is malware that typically targets a computer network by replicating itself to spread rapidly. Unlike viruses, worms do not need to infect other programs and do not need to be executed by a user or process.
answer: D
The primary difference between a virus and a worm is that viruses must be triggered by the activation of their host; whereas worms are stand-alone malicious programs that can self-replicate and propagate independently as soon as they have breached the system.
Viruses: A virus is a small piece of software that piggybacks on real programs. For example, a virus might attach itself to a program such as a spreadsheet program. Each time the spreadsheet program runs, the virus runs, too, and it has the chance to reproduce (by attaching to other programs) or wreak havoc.
Worms: A worm is a small piece of software that uses computer networks and security holes to replicate itself. A copy of the worm scans the network for another machine that has a specific security hole. It copies itself to the new machine using the security hole, and then starts replicating from there, as well.
Viruses have to attach themselves to something else AND someone click on them to replicate. Worms just replicate by themselves EVERYWHERE.
