Microsoft researchers have discovered that North Korean hackers are exploiting a Chrome zero-day vulnerability to steal cryptocurrency. This security issue has prompted Google to release a new Chrome update that addresses four high-severity vulnerabilities across Windows, Mac, and Linux desktops. Meanwhile, Google is also introducing new features to Chrome, such as tab groups, which will now be available across all devices, including iOS and Android. These features aim to help users keep their tabs organized and accessible across different platforms.
