Nubeva Secures New U.S. Patent for AI-Driven Ransomware Recovery in Large Data Storage Environments

Patent Expands Nubeva's Leadership in Computational Intelligence and Ransomware Reversal Technologies

SAN JOSE, Calif., February 23, 2026 - Nubeva Technologies (TSX-V: NBVA), a cybersecurity company specializing in ransomware decryption and recovery, today announced that the U.S. Patent and Trademark Office will officially grant the company a critical new patent on Tuesday, February 24, 2026. This technology arrives at a crucial time as more enterprises are reversing the trend of cloud migration, bringing storage back into their own datacenters to support artificial intelligence initiatives-a shift that is dramatically increasing on-premise storage volumes. To address the unique threats facing these massive data environments, the new patent, titled "Recovering from a Ransomware Attack Using Computational Intelligence", names Nubeva Chief Executive Officer Randy Chou as the inventor.

This new patent marks a significant milestone in Nubeva's mission to redefine ransomware recovery, specifically addressing the growing threat against large-scale enterprise data storage systems. The newly protected intellectual property covers innovations for recovering large data volumes-such as Virtual Machine Disk (VMDK) images-that are too massive to be encrypted as a single unit by attackers and are instead targeted in multiple scattered subsections, often concurrently across multiple processing units.

By leveraging advanced computational intelligence, including machine learning mechanisms and edge agents, Nubeva's technology can analyze the contents of compromised data storage, identify complex encryption patterns in sparsely populated files, and automatically test and apply harvested encryption keys to reconstruct the data.

"This patent reinforces the strength of our innovation and our dedication to helping organizations respond to and recover from ransomware attacks with greater speed and confidence," said Randy Chou, CEO of Nubeva. "As threat actors shift their tactics to compromise high-capacity virtualized storage, conventional recovery tools often fail under the weight of corrupted encryption states or multi-key complexities, resulting in devastating data loss even in cases where victims have paid the ransom."

The patent bolsters Nubeva's growing portfolio of intellectual property, which underpins the company's unique approach to ransomware decryption, recovery, and support automation. By utilizing AI to narrow down key variations, detect high-entropy patterns, and rapidly generate automated decryptors, Nubeva ensures its technology stays at the forefront of cybersecurity innovation, delivering efficient, reliable, and scalable solutions to enterprise and government customers worldwide.
