Keystone Nexus App Hit by Cyberattack, No User Assets Affected

For a hardware wallet maker, an app-layer breach is the reputational test that matters, since trust hinges on the assumption that the software surface never touches keys. Keystone's claim of no asset or personal-data exposure is the central assertion to verify — an independent audit or post-mortem would carry more weight than the company's own statement. The split rollout is the practical friction point: Android users can update now while iOS users wait on App Store review, leaving a security patch unevenly distributed across the user base. Whether Keystone publishes technical detail on the attack vector is the open question.
