The MemcycoFM Show: Episode 5 - DNS Cache Poisoning Prevention: How to Protect Accounts in Real-Time

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.
