Europol Warns Crypto Wallets Face Quantum Threats

The agency said migration could take years and urged developers, custodians and users to start testing quantum-resistant systems now.

  • On Oct 7, Europol published two reports examining how future quantum computing advances could threaten digital assets and encrypted information, urging the industry to begin security preparations now.
  • While current machines lack the capability, Europol noted that quantum computers could theoretically derive private keys from exposed public keys, potentially allowing attackers to sign transactions without permission.
  • NIST-Approved standards including FIPS 203, FIPS 204, and FIPS 205 provide quantum-resistant cryptography frameworks that organizations are beginning to implement ahead of practical threats.
  • BitGo and Silence Laboratories tested post-quantum multiparty computation signing earlier this year, while Coinbase and Sui are developing infrastructure to support future quantum-resistant authentication methods.
  • Europol also warned of "harvest now, decrypt later" tactics targeting confidential government and medical data, emphasizing that Migration requires complex coordination across decentralized networks to protect assets long-term.

Kripto novčanici glavna su točka izloženosti budućim kvantnim napadima, upozorava Europol, dok bi napadači šifrirane podatke koje prikupe i pohrane danas mogli dešifrirati godinama kasnije uz pomoć dovoljno moćnih kvantnih računala.

On October 7, 2026, Europol published a report calling for Bitcoin (BTC) to be prepared in the post-quantum era. The European agency is particularly concerned about the portfolios whose public key is already visible, as no cryptographic fix will be able to protect them from quantum computers. More than 6 million BTC would be concerned, or about 30% of the offer in circulation. The Bitcoin article: Europol grows for a post-quantum migration appea…
