Deep dives
Your light sensor can spy on you
Researchers have discovered that light sensors in devices like smartphones, tablets, and smart TVs can be used to detect light intensity changes and infer what content a user is interacting with. By cross-referencing data from the ambient light sensor on a tablet with tailored videos displayed on the screen, hackers could generate images of a user's hands as they interact with the device. While this method is not easy to execute, it highlights the importance of considering the potential security risks associated with commonly overlooked sensors in devices.
Apple splitting the app store in the EU
In order to comply with the European Union's Digital Markets Act, Apple is planning to make adjustments to the app store specifically for users in the EU. This includes separating the app store in the EU from the rest of the world. While the full details of how this will be implemented are not yet available, this move aims to address concerns about Apple's monopolistic practices and increase competition within the EU app market.
New security feature in Apple devices
Apple is releasing a new security feature in its upcoming iOS 17.3 update. The feature, called stolen device protection, provides an extra layer of protection for users whose devices have been stolen and whose passcodes have been compromised. By enabling stolen device protection, users will be required to provide biometric authentication before performing sensitive actions, preventing unauthorized access to their iCloud accounts. This update addresses a real concern for users who may have their devices stolen and reinforces Apple's commitment to user privacy and device security.
Flaw in GPUs poses security risk
Millions of Apple, AMD, and Qualcomm GPUs have a vulnerability that could potentially allow hackers to steal data from the GPU's memory. While attackers would need to have existing operating system access on the target device to exploit this vulnerability, it highlights the importance of addressing security flaws in GPUs. The issue has been acknowledged by Apple, Qualcomm, and AMD, and efforts are being made to provide patches and fixes to mitigate the risk.
