Ep. 33: Following the Mail: Postal Intelligence in the Age of Crypto Crime

Aidan Larkin speaks with Tara Kavanaugh, a federal investigator with the U.S. Postal Inspection Service (USPIS) and liaison to the FBI's dark‑web opioid task force. Tara draws on a career spanning HUMINT work in the Middle East, signals intelligence at the NSA and crypto‑enabled investigations at USPIS to explain how modern crime moves across the mail system, the dark web, and digital‑asset ecosystems. She outlines the realities of mail‑based fraud, fentanyl supply chains, dark‑web vendor activity, and the growing “scamdemic,” while highlighting how postal data and blockchain analytics help identify offenders. They also discuss inter‑agency collaboration, investigative tooling and why asset recovery remains central to disrupting harm.⏱️ Timestamps00:00 – Early Career & Intelligence Background04:40 – USPIS Crypto Investigations06:45 – FBI Liaison Role & Dark‑Web Opioid Task Force12:50 – Using Postal Intelligence to Strengthen Federal Cases15:30 – Blockchain Tracing Patterns, Playbooks & Criminal Methods21:45 – Agency Readiness, SOPs & Evolving Crypto Capabilities25:45 – Crypto ATMs, Victim Risks & the Growing “Scamdemic”32:40 - The Modern Investigator’s Toolkit & Global Collaboration👤 About Our GuestTara Kavanaugh is a federal investigator at the U.S. Postal Inspection Service (USPIS) and liaison to the FBI’s Joint Dark‑Web and Opioid Task Force.
