Study Notes
Categories of Malware
- Malware can be categorized based on its propagation methods and the actions it performs upon targeting.
- Two primary classification criteria:
- Propagation Method: How malware spreads to reach targets.
- Actions/Payloads: What actions or damage the malware carries out once it reaches the target.
Types of Malware Based on Host Dependency
- Parasitic Code: Requires a host program to function effectively, examples include viruses.
- Independent Programs: Self-contained entities that do not depend on other programs, examples include worms, trojans, and bots.
Replication Characteristics of Malware
- Non-replicating Malware: Includes trojans and spam emails; these types do not replicate themselves.
- Replicating Malware: Includes viruses and worms; they are capable of self-replication, spreading independently to new targets.
