Quantum risk could make stolen encrypted data valuable years later

Attackers may exfiltrate encrypted data they cannot use today, potentially hoping that future quantum computers will enable its decryption. One scenario raised was that data described as encrypted could become readable in five years, but the precise purpose of large-scale theft may be unclear when it is discovered.

When attackers take terabytes of data without immediately selling or using it, the analysis suggests the activity still reflects an underlying motive. Possible explanations include delayed decryption or training models, making quantum computing a security issue that warrants some attention alongside AI.
