Embodiments of the present invention relate to a method and system for detecting and/or mitigating domain name system (DNS) spoofing Trojan horse (or Trojan) code. Trojan code (sometimes called malware or malicious software) is a common computer security problem. Some Trojans modify the DNS resolution mechanism employed by the infected computer, such that the computer traffic, when browsing the Internet, is routed to a location not intended by the rightful owner of the computer. The present invention can detect this phenomenon from a remote device or location and may take action to mitigate its effects.
