Patent number: 8316440Abstract: Detection for pharming attacks and specifically for changes in name-to-IP resolutions on a computer system using rules is described. The DNS settings and the Hosts file on a computer system are monitored and their modification information is saved as a part of the historical data over time. When an IP address is determined for a host name, various rules are applied to the IP address in connection with the saved historical data, such that each rule produces a score based on various criteria. Different rules may have different weights assigned to their scores. The scores of all the rules are summed up to produce a final score. If the final score is above a predefined value, then there is a suspicious change in the IP address, and an alert is sent. Otherwise, the host name and the IP address are saved as a part of the historical data.Type: GrantFiled: October 30, 2007Date of Patent: November 20, 2012Assignee: Trend Micro, Inc.Inventors: Sheng-Chi Hsieh, Chao-Yu Chen, Chih-Chia Chen
