Michele Spagnuolo

Michele Spagnuolo is an Italian information security engineer who has worked at Google since 2014. He currently serves as a Staff Information Security Engineer and leads the Agent & Web Observability team within Google’s Information Security organisation. His long tenure at the company has placed him at the centre of internal security operations responsible for monitoring and protecting Google’s web infrastructure.

Spagnuolo is the creator of Security Signals, a bottom‑up security initiative that began as an internal project and gained external recognition after five years of development. He has presented at security conferences such as BSides Las Vegas, covering topics ranging from his Master’s dissertation research to emerging practitioner challenges in information security.

In June 2026, U.S. federal prosecutors charged him with insider trading, alleging that he used non‑public Google “Year in Search” data to place wagers on the prediction‑market platform Polymarket under the username “AlphaRaccoon.” The scheme reportedly generated over $1.2 million in profit. The charges highlight both his access to confidential search trends and his history as a long‑time, trusted employee at Google.
