Hackers Stockpile Encrypted Data for 2030s Quantum Decryption as Experts Warn RSA and ECC Face Early Risk
3 articles · Updated · CircleID · Jun 12
Summary
Bad actors are already stealing and storing encrypted corporate, banking and medical data to unlock later, in a “harvest now, decrypt later” strategy tied to expected quantum advances in the 2030s.
RSA and ECC public-key systems are expected to fall before common symmetric encryption, making carrier handoffs and other web exchanges the earliest likely targets as quantum machines improve.
10,000 qubits could crack ECC in about 1,000 days, while 26,000 qubits could do it in a day; labs have reached roughly 6,100 qubits, but error rates still block widespread decryption use.
Post-quantum cryptography built on lattices and hash-based methods is being deployed to protect live networks, but it cannot undo the risk to large stores of data encrypted under today’s algorithms.
Is your past decade of 'secure' data already a ticking time bomb for future quantum hackers?
With experts split on the timeline, are we sleepwalking into a global digital security crisis?
The Urgent Race to Post-Quantum Cryptography: Defending Against the "Harvest Now, Decrypt Later" Threat Before Q-Day
Overview
The report highlights the urgent threat posed by 'Harvest Now, Decrypt Later' (HNDL) attacks, where adversaries are actively stealing and storing encrypted data today, expecting that future quantum computers will be able to decrypt it. As quantum technology advances, this stolen data could become vulnerable, making it essential for organizations to prepare now rather than wait for 'Q-Day'—the point when quantum decryption becomes practical. The potential of advanced quantum computers to break current encryption means global preparation is necessary to protect sensitive information from being exposed in the future.
