Why each option
Passive attacks involve observing or collecting information without altering system resources, with dumpster diving, eavesdropping, and shoulder surfing being common examples of such reconnaissance.
Dumpster diving is a passive attack where an attacker sifts through discarded materials to find sensitive information without directly interacting with live systems.
Placing a backdoor is an active attack because it involves intentionally modifying a system or software to create a hidden means of unauthorized access.
Eavesdropping is a passive attack that involves secretly listening to or intercepting communications without detection or modification.
Shoulder surfing is a passive attack where an attacker directly observes a person entering sensitive information like passwords or PINs.
