Bogus emails that form the basis of phishing attacks contain URLs that direct the victim to a single IP address, which hosts the so-called ‘smart redirector’. When the potential victim clicks on the link, the redirector checks all related phishing websites, identifying which sites are still live before redirecting the user to one of them.
RSA Cyota senior product manager Andrew Moloney said: “As anti-phishing vendors become more adept at shutting down phishing websites, inevitably the fraudsters are looking at ways to minimise the effect this has on their hit rates.
According to the Anti-Phishing Working Group, almost 50,000 phishing websites were created last year, with more than 7,000 appearing in December alone.
