Answer: A
Social engineering is based on the divulgence of private
information through dialogues, interviews, inquiries, etc.,
in which a user may be indiscreet regarding his or other's
personal data. A sniffer is a computer tool to monitor the
traffic in networks. Backdoors are computer programs left by
hackers to exploit vulnerabilities. Trojan horses are
computer programs that pretend to supplant a real program,
thus, the functionality of the program is not authorized and
is usually malicious in nature.
