Apple’s App Store now lists version 1.3.7 of Keystone’s Nexus App, identifying a network fix after the company linked a disruption in some services to a cyberattack.
The App Store release note is “Fix network issue.” Keystone said version 1.3.7 adds safeguards built on steps it took to protect its servers after the disruption.
Keystone makes hardware wallets and offers Nexus App as mobile wallet software. Keystone said its review has not indicated any impact to the assets or personal information of its users. It named Yanssie HK Limited as the developer users should check for and cautioned them against counterfeit app versions.
