Harvest Now, Decrypt Later: Why Quantum-Ready Attackers Are Already Stealing Your Encrypted Data

Sesame, salt, and substance. A flagship bake.
Summary
"Harvest Now, Decrypt Later" (HNDL) attacks are an active cybersecurity threat where adversaries intercept and store encrypted data today with the intent to decrypt it once cryptographically relevant quantum computers become viable. The article argues this is not a future problem but a present one, as sensitive data is already being collected and stored by attackers who are waiting for quantum computing to advance enough to break current encryption standards. Organizations need to recognize that the breach is already happening in terms of data exfiltration, even if the decryption hasn't occurred yet.
Key quotes
· 3 pulledThe data being targeted by quantum attacks is already moving across your network today.
Attackers know they can't break modern encryption yet. But they're collecting it anyway and, from their point of view, for good reason.
The breach happened, you just haven't seen it yet.
