The Log4j security flaw could impact the entire internet. Here's what you should know

The vulnerability, which was reported late last week, is in Java-based software known as "Log4j" that large organizations use to configure their applications -- and it poses potential risks for much of the internet.

Apple's cloud computing service, security firm Cloudflare, and one of the world's most popular video games, Minecraft, are among the many services that run Log4j, according to security researchers.
