Researchers discover a dangerous security gap in a widespread Bluetooth chip. Smartphones and smart home devices are affected.
Researchers have uncovered a serious vulnerability in the Bluetooth chip ESP32. This chip made by espressif system is installed in over a billion devices worldwide and enables both Wi-Fi and Bluetooth connections. Among other things, smartphones, laptops and smart home devices are affected.
According to an examination of “Tarlogic Security”, it is an undocumented backdoor that enables attackers to pretend to be a trustworthy device. Hackers could thus spy on sensitive data such as passwords and bank details unnoticed or even remotely control devices. You could activate microphones or cameras and obtain sensitive information, warn the security researchers.
Security gap in Bluetooth chips: Users are called up for increased vigilance
The threat to networked door locks and medical devices is particularly critical. Attachers could potentially take control of such vital systems, which could have devastating consequences.
Regular updates and the deactivation of unused functions are essential to protect yourself against any attacks. A safe network with strong passwords is also important to minimize the risk.
