Experts at Proofpoint uncovered a pharming attack that uses phishing to exploit router vulnerabilities and carry out malicious activities. Security firm Proofpoint revealed that its experts recently detected a spam campaign targeting organizations and primarily Brazilian Internet users. The spam campaign implements a very effective technique to spy on a victims Web traffic. The attackers exploited security vulnerabilities affecting home routers to gain access to the administrator console. Once obtained the access to control panel the hackers changed the DNS settings of the devices. Pharming attacks on a large scale could be run by replacing DNS servers used by the ISPs, or acting on the client side by manipulating the setting of routers.”]
