+1 CPE LIVE ATTACK SIMULATION

The Cookie-Bite Exploit

Using Digital Crumbs to Bypass MFA

Wednesday, August 20, 2025 11 a.m. ET | 4 p.m. BST Virtual Zoom Session Mark Vaitsman & Brock Bauer

Cookie-Bite — the attack most security tools never see coming.

This technique uses stolen authentication cookies to hijack a user’s active cloud session, bypass MFA, and keep persistence without ever needing credentials.

Join our experts to see a live simulation of the entire attack flow — from building the cookie stealer and breaching the network to escalating privileges and stealing data — all while staying invisible to traditional defenses.

Registration closed.
