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

Recon Talks Area

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.
