Data Bouncing: How HTTP Headers Leak Data | The Cyber Security Podcast
Your tools say “secure.” Your headers say “leaking.”
In this Threat Talks Deep Dive, ON2IT’s Luca Cipriano (CTI & Red Team Lead) exposes Data Bouncing—a stealthy exfiltration trick that hides inside HTTP headers and abuses DNS lookups through trusted third parties. We show the demo, decode the psychology of the attack, and translate it into Zero Trust moves you can deploy today.
