What is Malware in Cyber Security?

Malware, short for malicious software, is a term used to describe any software specifically designed to disrupt, damage, or gain unauthorized access to computer systems, networks, or devices. It encompasses many harmful software types, including viruses, worms, Trojans, ransomware, spyware, and adware. Malware is one of the most significant threats in the realm of cybersecurity, posing serious risks to individuals, businesses, and even governments worldwide.


Viruses: Malicious code that attaches itself to legitimate programs or files and spreads when those files are executed.
Worms: Self-replicating malware that spreads across networks and systems, often without requiring the user interaction.
Trojans: Disguised as legitimate software, Trojans trick users into installing them, enabling attackers to gain unauthorized access or steal sensitive information.
Ransomware: Encrypts files or locks users out of their systems, demanding a ransom for their release.
Spyware: Secretly monitors user activities, capturing sensitive information such as passwords, keystrokes, and browsing habits.
Adware: Displays unwanted advertisements and can track user behavior for marketing purposes, often degrading system performance.
Rootkits: Conceals malicious software within the operating system, allowing attackers to maintain persistent access and control over compromised systems.
