David Bennett warns tax leak exposes French Bitcoin owners
- A French tax breach leaked 678,000 taxpayer files, exposing cryptocurrency owners to physical home extortion.
- Security researchers rank France as the world's top location for physical wrench attacks against crypto holders.
A French tax breach exposed the physical addresses of 678,000 taxpayers. For local Bitcoin owners who declared their holdings, the leak creates an immediate physical target on their front doorstep.
A hacker operating under the handle zero bytes compromised internal servers at the DGFIP, France's tax administration agency. The exfiltrated files detail personal names, home addresses, income brackets, and official tax correspondence.
The compromise lands in a nation already struggling with physical crypto extortion. Security researcher Jameson Lopp tracks France as the world's leading jurisdiction for wrench attacks, where physical violence or forced captivity is used to compel private key transfers.
On Bitcoin And, host David Bennett emphasized that publishing physical addresses tied to verified asset disclosures converts administrative compliance into personal danger.
"Leaking addresses and income tiers creates an existential physical threat."

The breach exposes the stark divide between individual self-custody and institutional investment models. While French citizens face physical risk at home, Wall Street firms are rapidly expanding paper exposure to Bitcoin through regulated spot ETFs without holding private keys directly.
Recent regulatory filings show Edelman Financial Engines accumulated a $34 million position in spot Bitcoin ETFs, surpassing its $25 million stake in Amazon. Tudor Investment Corporation, managed by Paul Tudor Jones, disclosed nearly $23 million in BlackRock's IBIT ETF.
While regulatory oversight in California moves to restrict unmonitored AI chatbots under Senate Bill 903 to protect psychological safety, state tax authorities in Europe failed to maintain basic physical data security.
For self-custodians, administrative leaks turn sovereign money into a physical target.
