A privacy flaw within the Android model of Apple and Google’s COVID-19 publicity notification app probably allowed different preinstalled apps to see delicate knowledge, together with if customers had contact with a COVID-positive particular person. Google is now engaged on rolling out a repair.
Privateness evaluation agency AppCensus first seen the bug in February and reported it to Google. Nonetheless, in response to The Markup, Google failed to deal with it on the time. The bug goes towards a number of guarantees made by Apple CEO Tim Prepare dinner, Google CEO Sundar Pichai, and a number of other public well being officers that the info collected from the publicity app wouldn’t be shared past a person’s gadget.
“The repair is a one-line factor the place you take away a line that logs delicate info to the system log. it doesn’t affect this system, it doesn’t change the way it works,” stated Joel Reardon, co-founder and forensics lead of AppCensus in the identical interview with The Markup. “It’s such an apparent repair, and I used to be flabbergasted that it wasn’t seen as that.”
The article additionally shared a quote from Google spokesperson José Castañeda, who acknowledged “We had been notified of a difficulty the place the Bluetooth identifiers had been quickly accessible to particular system stage functions for debugging functions, and we instantly began rolling out a repair to deal with this.”
To ensure that the publicity notification system to work, it must ping anonymized Bluetooth alerts of units with the system activated. Then, within the occasion one of many customers exams constructive for COVID-19, it really works with well being authorities to ship an alert to different customers who got here into contact with that particular person with corresponding alerts which might be logged within the telephone’s reminiscence.
