Malicious software designed to damage, disrupt, or gain unauthorised access to computer systems.
Malware (malicious software) is any software designed to cause harm—stealing data, damaging systems, enabling unauthorised access, or disrupting operations. Malware encompasses many categories: viruses, worms, trojans, ransomware, spyware, adware, rootkits, and more. Malware spreads through email attachments, malicious websites, infected software, USB drives, and network vulnerabilities. Defence requires multiple layers: email security, endpoint protection, web filtering, user awareness, and regular patching.
Why It Matters
The DSC Perspective:
Malware is the mechanism behind most cyber attacks. Understanding malware types helps you evaluate protections and respond to incidents. Modern endpoint protection must detect both known and unknown malware.
