Millions of Android and iOS users are at risk due to hardcoded credentials found in popular apps. These credentials, including AWS and Azure authentication keys, have been exposed, making cloud services vulnerable. Affected apps on Google Play include Pic Stitch, Meru Cabs, Sulekha Business, ReSound Tinnitus Relief, Saludsa, Chola Ms Break In, EatSleepRIDE Motorcycle GPS, and Beltone Tinnitus Calmer. The exposure of these cloud keys has raised significant cybersecurity concerns. Affected apps are also found on Apple's App Store.
