A North Korean hacking group earlier in August exploited a previously unknown bug in Chrome to target organizations with the goal of stealing cryptocurrency, according to Microsoft. According to the report, the hackers exploited a flaw in a core engine within Chromium, the underlying code of Chrome and other popular browsers, like Microsoft’s Edge. When the hackers exploited the vulnerability, it was a zero-day, meaning the software maker — in this case, Google — was unaware of the bug and as such had zero time to issue a fix prior to its exploitation.
