Facebook Security Team

Facebook Headquarters – Menlo Park, California.

At exactly 2:17 AM PST, a flagged email notification appeared in the inbox of Nathan Caldwell, Facebook's Chief Security Officer (CSO). As the head of one of the world's most advanced cybersecurity teams, Nathan received countless pitches, security concerns, and spam messages daily. Most of them never made it past his filters—yet this one did.

Sipping his third cup of coffee, he skimmed through the email, his brows furrowing slightly as he read the contents.

A minute later.

Nathan's fingers tapped against his desk. His instinct told him this was either a phishing attempt, a scam, or someone grossly overestimating their abilities. But the technical depth of the email was intriguing—it wasn't the usual marketing jargon.

Without hesitation, he forwarded the email to Facebook's Red Team, a specialized group of security engineers whose sole job was to simulate and counteract cyber threats.
