Europol warns crypto wallets are the weak spot for future quantum attacks

  • —Europol published two reports via EC3 on October 7, 2026
  • —About 6.9 million BTC in legacy or reused addresses are exposed, worth $586 billion
  • —HNDL risk: attackers harvest encrypted data now to decrypt it later
  • —The European Commission requires member states to start post-quantum migration by end-2026
Why it matters: The cryptographic transition will take years, and billions of dollars sitting in legacy addresses depend on it.
