Question 1

What are the main types of malware?

Accepted Answer

The major malware categories include viruses (self-replicating code that attaches to programs), worms (self-propagating across networks), trojans (disguised as legitimate software), ransomware (encrypts files for payment), spyware (monitors user activity), adware (displays unwanted ads), rootkits (hide deep in the OS), and botnets (networks of compromised machines controlled remotely). Each type has distinct behaviors and indicators.

Question 2

How do security analysts classify malware?

Accepted Answer

Analysts use static analysis (examining code without execution), dynamic analysis (running in sandboxes to observe behavior), and behavioral indicators such as network traffic patterns, file system changes, registry modifications, and process injection techniques. Machine learning models trained on these features are increasingly used for automated classification at scale.
