Security+ Exam Prep Question of the Week

A malware scanner is least effective against what type of attack?

  1. Pharming
  2. Logic bomb
  3. Trojan horse
  4. backdoor

The correct answer is 1.

Pharming is generally an attack on DNS. Pharming is used to steal or redirect traffic toward some other destination. The most common form of pharming involves stealing or redirecting Web traffic. Since pharming is an attack that can take place external to a system, in the DNS resolution processes or on external DNS servers, a malware scanner is typically not able to detect this attack. A network IDS might be more appropriate for detecting pharming.
