Harvest now, decrypt later (HNDL) attacks represent a significant risk as attackers collect encrypted data today, anticipating the future capabilities of quantum computers to break the encryption. This stealthy approach allows them to exploit sensitive information once quantum computing becomes advanced enough to decrypt previously captured data. Organizations must proactively adopt post-quantum cryptographic measures to safeguard against this looming threat.
