Quantum crypto attack may resemble key theft

• A quantum-based crypto attack could look like ordinary private key theft, according to Quantus founder Konstantinos Karagiannis.
• He said the first successful quantum attack may be difficult to distinguish from a standard wallet breach.
• The comments highlight growing concerns about quantum computing and crypto security.

A quantum-based crypto attack could look like ordinary private key theft, according to Quantus founder Konstantinos Karagiannis.

Karagiannis said the first successful quantum attack may be difficult to distinguish from a standard wallet breach.

He said a stolen private key would appear similar whether it was taken through malware, phishing, or quantum computing.

Karagiannis said blockchain investigators may not immediately recognise a quantum attack when funds move from a compromised wallet.

Security researchers are studying how quantum computing could affect cryptographic systems used by cryptocurrencies.

Most major blockchain networks continue using cryptographic methods that researchers believe are secure against current quantum computers.

Karagiannis said the crypto industry should prepare for future quantum risks even if practical quantum attacks are not yet common.
