Why You Should Watch

For security teams, it’s no great revelation to say that DNS cache poisoning prevention is essential for guarding against attacks using that vector. But it’s easier said than done. While traditional network-layer defenses like DNSSEC reduce poisoning risk, they can’t fully prevent it. Downstream – after redirection – bad actors await, ready to harvest credentials, bypass MFA, and take over accounts. To prevent account takeover (ATO) fraud resulting from DNS poisoning, network-layer protections can be fortified with real-time, browser-layer defenses capable of detecting phishing attempts as users interact with malicious sites. These measures can neutralize stolen credentials using decoy data, disrupt attackers, and block suspicious devices, stopping attacks before account compromise occurs. Before we unpack the detail, let’s cover the basics.

Key Takeouts

What is DNS Poisoning?

DNS poisoning, also known as DNS cache poisoning, is a technique where attackers inject false information into DNS resolver caches. This causes internet users trying to visit legitimate websites to be redirected silently to fake, attacker-controlled sites.

Bridging DNS Poisoning

DNS manipulation doesn’t just reroute traffic, it reroutes trust. These attacks land users on clone sites with real-looking URLs, padlocks, and no obvious red flags. Once the redirect happens, network-layer defenses go silent.

Close DNS Poisoning Gaps

Memcyco doesn’t prevent DNS poisoning itself but stops phishing and damage caused by digital impersonation attacks after redirection. By focusing on the critical moments after redirection, Memcyco effectively stops phishing and impersonation attacks.
