Flashcards - M6: Malware Threats
Published on January 19, 2025
Define malware.
Malicious software designed to disrupt, damage, or gain unauthorized access to systems (viruses, worms, trojans, etc.).
How do worms differ from viruses?
Worms: Self-replicating across networks, no user interaction required.
Viruses: Require user action (e.g., opening an infected file) to spread.
What is a trojan horse?
A program disguised as legitimate software that performs malicious activities once installed.
What is ransomware?
Malware that encrypts files and demands payment (usually in cryptocurrency) for decryption.
Give an example of a malware analysis technique.
Sandboxing (e.g., using Cuckoo Sandbox) or static/dynamic code analysis (e.g., IDA Pro).
What is spyware?
Software that secretly gathers user information (keystrokes, browsing habits) and sends it to a third party.
How can malware commonly be delivered?
Phishing emails, malicious links/attachments, drive-by downloads, or infected USB devices.
