What is Malware
Introduction to Malware
Malware, short for "malicious software," refers to any software designed to harm, exploit, or compromise a computer system or network. It can disrupt operations, steal sensitive data, or even allow unauthorized access to systems. Malware is a major threat to cybersecurity worldwide.
Types of Malware
- Virus: A program that attaches itself to legitimate software and spreads across systems, damaging files and software.
- Trojan: Disguised as legitimate software but grants unauthorized access to attackers.
- Ransomware: Encrypts files and demands payment for their release.
- Spyware: Secretly monitors user activities and collects personal data.
- Adware: Displays unwanted advertisements and can redirect web traffic.
How Does Malware Spread?
Malware can spread through email attachments, infected websites, downloads, or even USB devices. Cybercriminals use malware to steal data, extort money, or disrupt business operations. Common entry points for malware include phishing emails, compromised software, and weak network security.
Protecting Against Malware
To protect against malware, it's crucial to use up-to-date antivirus software, regularly patch and update systems, avoid suspicious downloads, and enable firewalls. Additionally, educating users about common attack vectors such as phishing can help minimize risk.
