Study Notes
Malware Overview
- Malware is malicious software designed to harm, exploit, or otherwise compromise devices and networks.
Viruses
- Definition: Self-replicating program that attaches to clean files and spreads throughout a computer system.
- Activation: Requires user action (e.g., opening an infected file).
- Functionality: Can corrupt or delete files, causing damage to the system.
Worms
- Definition: Standalone malware that replicates itself to spread to other computers.
- Propagation: Spreads through network connections without user intervention.
- Impact: Often consumes system resources, leading to slowdowns or crashes.
Trojan Horses
- Definition: Malicious software disguised as legitimate software.
- Execution: Tricks users into installing it, thinking it is safe.
- Consequences: Can create backdoors for hackers, steal data, or deploy other malware.
Spyware
- Definition: Software that secretly monitors and collects user information.
-
Functionality:
- Tracks browsing habits and personal data.
- Can manipulate computer settings without consent.
- Goal: Generally used for identity theft and privacy invasion.
Ransomware
- Definition: Malware that encrypts a victim's files, demanding payment for decryption.
- Distribution: Often disseminated via email attachments or compromised websites.
- Impact: Can lead to data loss, operational disruptions, and financial loss if the ransom is paid.
Summary
- Understanding different types of malware is crucial for effective prevention and response.
- Regular updates, security software, and user education can help mitigate risks associated with malware threats.
