Which term describes spyware installed without user knowledge that piggybacks onto other applications to spread?

• A. Desktop Spyware
• B. Email Spyware
• C. Form-Grabbing-Based Keylogger
• D. Spyware Propagation

Answer: (D)

The main idea here is how certain spyware spreads. When spyware is described as piggybacking onto other applications to spread, it’s talking about its propagation: the ability to hitch a ride with legitimate software, installers, or updates so it can spread to more systems without the user recognizing it. This spreading behavior is captured by the term spyware propagation, which focuses on the method of dissemination rather than what the spyware does once installed or where it resides. The other options describe aspects that aren’t about spreading. Desktop Spyware implies spyware on the computer in general. Email Spyware would involve using email as a vector to spread or exfiltrate data. A Form-Grabbing-Based Keylogger refers to a tool that captures form data or keystrokes, not the mechanism by which the spyware travels between apps.
