In the evolving landscape of cybersecurity, the ‘harvest now, decrypt later’ (HNDL) strategy represents a looming threat, particularly for data stored at rest. This approach, adopted by cyber adversaries, involves collecting encrypted data with the intent to decrypt it at a later time, potentially leveraging future advancements in computing power or cryptographic breakthroughs, such as quantum computing. As organizations store increasing volumes of sensitive data, the risk that this data could be harvested today and decrypted tomorrow becomes a pressing concern. However, a novel defensive mechanism known as microsharding emerges as a promising solution to mitigate the risks associated with HNDL attacks.
