Cyber criminals take up a bit of pharming

Regional IT managers are being warned by security firms of the increased threat from pharming - in which users are tricked into visiting fraudulent web sites.

Unlike the more widely reported ‘phishing’ — in which users are sent e-mails to encourage them to visit fake web sites — pharming attacks work by hacking into a legitimate DNS server and changing the IP address. As the user believes they are visiting the genuine site, they are more likely to not be suspicious and to give out information. Security firm Trend Micro warns that such attacks are extremely difficult to defend against and therefore are extremely dangerous. “The pervasive use of the web and complexity of protecting against web threats combine to form perhaps the greatest challenge to protecting the privacy of personal information and the confidentiality of business information in a decade,” said Samir Kirouani, MEA senior sales engineer at Trend Micro. “Traditional means do not provide adequate protection from these threats. Advanced multi-layered security solutions are required to offset this increasingly complex threat vector.”
