Study Notes
Types of Malicious Software (Malware)
-
Propagation Mechanisms
- Viruses infect existing files, spreading as they are shared across systems.
- Worms exploit software vulnerabilities and can replicate through drive-by downloads, copying themselves onto other systems without user intervention.
- Social engineering techniques manipulate users into disabling security measures, facilitating the installation of Trojans or enabling responses to phishing scams.
-
Payload Actions of Malware
- Corruption of system files or data, leading to potential data loss or system failure.
- Theft of service, turning infected systems into zombie agents within a botnet, which can be used for coordinated attacks.
- Theft of sensitive information, often through keylogging, which captures keystrokes to access private data like passwords.
- Stealthing techniques conceal the malware's presence on the system, making detection and removal more difficult.
