Spectre (security vulnerability)

Spectre is a security vulnerability that affects computer processors. Your computer uses a processor to keep track of your instructions and activities. Spectre can make the processor act in a way that it should not, and this can be used to steal information from your computer. Think of it like someone sneaking into your house and taking your stuff without you noticing - that is what Spectre can do. Fortunately, there are ways to protect yourself, like downloading the latest software updates for your computer.
