Europol warns crypto wallets face quantum threats
Europol has warned that future quantum computers could threaten cryptocurrency wallets and long-lived encrypted data, urging the crypto industry to begin security preparations before practical attacks become possible. SummaryEuropol says quantum computers could expose cryptocurrency wallets by deriving private keys from public keys.Europol recommends phased migration to post-quantum cryptography, stronger wallet security, and improved key management practices.NIST has finalized three post-quantum standards and urges organizations to begin migration as soon possible.Bitcoin developers are debating post-quantum migration proposals while custodians test quantum-resistant wallet controls and signatures.Europol says there is no clear evidence harvest-now-decrypt-later attacks are being systematically used at scale. Europol published two reports on Oct. 7 examining how advances in quantum computing could affect digital assets and sensitive information. The agency said the timing of a capable quantum computer remains uncertain, but upgrading cryptographic systems across decentralized networks could take years. The first report focuses on cryptocurrency wallets, while the second examines attackers storing encrypted information today for possible decryption years later. Europol did not say current quantum machines can break cryptocurrency security.
