Which example is specifically described as targeted malware?

### Why this is right The material identifies Stuxnet as an example of targeted malware, which is tailored to a specific target and can be difficult to detect, prevent, and remove. ### The concept Mass malware aims to infect many systems; the lesson names WannaCry as an example. Targeted malware is designed with a particular target in mind and may require advanced analysis. The distinction concerns targeting and scale, not whether the malware is harmful. ### The other options - **B. WannaCry**: The material gives this as an example of mass malware, which seeks broad infection. - **C. A generic spam message**: Spam may carry malware, but the message alone is not the stated targeted-malware example. - **D. A routine registry backup**: A backup is an administrative action, not malware. ### Terms - **Targeted malware**: Malware tailored to a specific target. - **Mass malware**: Malware intended to infect as many systems as possible. ### Remember In this lesson, Stuxnet illustrates targeted malware and WannaCry illustrates mass malware.
