Amnesty International has reported that Google has patched critical vulnerabilities in Android that previously allowed authorities to unlock devices using Cellebrite’s forensic tools. These zero-day vulnerabilities, discovered during an investigation into the hacking of a student protester’s phone in Serbia, affect over a billion Android devices. The collaboration between Amnesty and Google’s Threat Analysis Group led to the identification and fixing of these flaws. Amnesty emphasized the risks to digital privacy for activists and journalists, noting that unauthorized access to their devices undermines human rights. As a precaution, experts recommend that activists consider switching to iPhones due to ongoing security concerns.
