Worms, on the other hand, are standalone programs that can reproduce and spread without the need for a host file. Trojans, named after the Greek mythological horse, appear harmless but are designed to trick users into installing them, allowing cybercriminals to gain unauthorized access to their systems. Ransomware encrypts files and demands payment in exchange for their release, while spyware secretly monitors and collects sensitive information. Finally, adware bombards users with unwanted advertisements and pop-ups.
It’s important to note that these are just a few examples of the many types of malware that exist. Cybercriminals are constantly evolving their tactics, making it crucial to stay informed about the latest threats and vulnerabilities.
