It’s what you never want to hear: An important service, used by millions, has a critical vulnerability. In a story that broke this week, the service in question was Zoom. The vulnerability, had it been exploited, would have allowed bad actors to run whatever code they wanted on a user’s machine.
In this case, though, the story has a happy ending. Often when you hear about vulnerabilities in software, it’s because they’ve already been exploited by hackers — specifically, black hat hackers, the term for hackers who act maliciously.
