Is your company's most critical blind spot hiding in plain sight? While most security teams focus on firewalls and web traffic, attackers are increasingly using the internet's phonebook—the Domain Name System (DNS)—as a secret backdoor for malware delivery, data theft, and command and control.
In this episode of The Defenders Log, host David Redekop sits down with cybersecurity educator Josh Kuo from Infoblox to uncover the shocking ways DNS is weaponized. Josh shares jaw-dropping stories from the field, explaining complex threats in a way that anyone can understand. Learn how a simple DNS query can be used to exfiltrate your most sensitive data and how Protective DNS is becoming an essential layer of defense for modern organizations.
Whether you're a CISO, a network admin, or just passionate about security, this is a conversation you can't afford to miss.
