Malware: Viruses, Worms, Trojans, Ransomware
Learn how different malware types infect, spread, and cause damage.
What is Malware?
Malware (malicious software) is any software intentionally designed to cause damage, gain unauthorized access, or disrupt systems. It is the primary tool of cybercriminals and nation-state actors.
Viruses
A virus is malware that attaches itself to legitimate programs or files. It requires human action to spread (opening an infected file). When executed, it replicates and may corrupt files, steal data, or open backdoors.
