Which of the following is a non-electric attack method used to obtain information?

• A. Shoulder Surfing
• B. Social Engineering
• C. Dumpster Diving
• D. Denial of Service

Answer: (A)

Shoulder surfing is a non-electronic way to gain information by visually watching someone enter sensitive data, such as passwords or PINs. It relies purely on observation, so no devices or electronics are needed. The risk comes from being close enough to see the keystrokes or screen as the user authenticates, making it a direct method to capture credentials in public or shared spaces. Other options involve manipulating people (social engineering) or collecting discarded documents (dumpster diving) or disrupting services (denial of service), which either target different avenues or have a different objective than quietly obtaining credentials through viewing. Thus, shoulder surfing best fits a non-electric attack method used to obtain information.
