A "hidden feature" was found in a Chinese-made Bluetooth chip that allows malicious actors to run arbitrary commands, unlock additional functionalities, and extract sensitive information from millions of Internet of Things (IoT) devices worldwide. The ESP32 chip's affordability and widespread use have made it a prime target for cyber threats, putting the personal data of billions of users at risk. Cybersecurity researchers Tarlogic discovered the vulnerability, which they claim could be used to obtain confidential information, spy on citizens and companies, and execute more sophisticated attacks.

Amnesty International said that Google fixed previously unknown flaws in Android that allowed authorities to unlock phones using forensic tools. On Friday, Amnesty International published a report detailing a chain of three zero-day vulnerabilities developed by phone-unlocking company Cellebrite, which its researchers found after investigating the hack of a student protester’s phone in Serbia. The flaws were found in the core Linux USB kernel, meaning “the vulnerability is not limited to a particular device or vendor and could impact over a billion Android devices,” according to the report.

A recently discovered trio of vulnerabilities in VMware's virtual machine products can grant hackers unprecedented access to sensitive environments, putting entire networks at risk. If exploited, these vulnerabilities could allow a threat actor to escape the confines of one compromised virtual machine and access multiple customers' isolated environments, effectively breaking all security boundaries. The severity of this attack is compounded by the fact that VMware warned it has evidence suggesting the vulnerabilities are already being actively exploited in the wild.

The US Department of Justice has announced charges against 12 Chinese hackers accused of targeting over 100 American companies, including the US Treasury.
