Researchers have discovered Google's decentralised COVID-19 contact-tracing system recently amended a privacy flaw that exposed sensitive information stored on Android devices. AppCensus researchers identified the flaw, which allowed hundreds of pre-installed Android applications to scoop up contact-tracing data in user analytics and crash reports. In related news, Sky News reports the UK will roll out a vaccine passport scheme via an app supported by the NHS. Transport Secretary Grant Shapps said the app "will be the NHS app that is used for people when they book appointments," not the NHS' contact-tracing app. Meanwhile, The Register reveals 78 MPs have come together with campaigners to oppose COVID status certificates as "divisive and discriminatory".
