of Malware: A Deep 
Dive for Ethical 
Hackers
In cybersecurity, ethical hacking is vital to defend against evolving 
digital threats. Malware, a persistent adversary, includes harmful 
programs designed to infiltrate systems without consent. 
Understanding malware¾s types, spread methods, and impacts 
empowers ethical hackers to identify vulnerabilities, simulate 
attacks, and strengthen defenses.
Malware Types: 
Viruses, Worms, and 
Trojans
