Top Layer Defends DNS Cache Poisoning

Security solution provider Top Layer Networks (toplayer.com) announced on Wednesday that its Attack Mitigator IPS 5500 can now be used as a defense against a new scam that preys on victims using "DNS Cache Poisoning."

The newest form of cyber-theft gives false information to DNS servers, allowing hackers to re-direct users to illegitimate Web sites. While in the past, links to fake Web sites were found in emails victims had to access themselves, "pharming" involves the subtle re-direction of a user's browser from a legitimate Web site to a hacker's "look alike" page.

The victim is under the impression that they are visiting a trusted Web site from their financial institution, when they are submitting personal data directly to a scammer. Using a built-in checking system, the IPS 5500 prevents customers from being redirected to a false site.

"In recent weeks there have been a number of DNS poisoning attacks that have all the earmarks of a proof-of-concept that has the potential to be the next wave of phishing scams" says Peter Randall, CEO and president of Top Layer Networks. "Internet service providers have an obligation to protect their DNS infrastructures from these sophisticated attacks or face the reality of possible liability as users' confidential information and financial accounts are compromised."
