Panel Discussion - Recon First Thinking: Winning Bounties Without Telling the Firewalls

Recon Village @ DEF CON 338th, 9th and 10th August 2025

Abstract

What if you could earn bounties without ever touching the app?

This panel explores how top hackers use Recon-First Thinking to silently uncover shadow assets, misconfigured SaaS, and forgotten APIs - all without triggering alerts or waking up firewalls.

Less noise. More signal. Bigger payouts.

Speakers

Rohit Grover

Penske Truck Leasing, Application Security Lead

I’m a cybersecurity professional with an M.S. in Cybersecurity and a deep interest in OSINT and recon methodologies. My work involves developing cloud-native, customer-facing applications that manage high-sensitivity PII and identity data. I lead efforts around secure authentication (OAuth2/OIDC), encrypted communications (TLS), and IAM unification across platforms. Given the attack surface of public-facing apps, recon and surface enumeration are part of my ongoing threat modeling and hardening strategy.
