maybe it's a black widow?
Could that be an immature black widow male?
could be a male crab spider, or a writing spider.
The spider you are referring to is likely the black widow spider. The female black widow has a distinct red hourglass shape or white crescent on its abdomen. They are known for their venomous bite, so caution should be taken when encountering them.

The spider you are describing sounds like a daring jumping spider (Phidippus audax). They are known for their black and furry bodies with white spots on their backs and white stripes on their legs. Daring jumping spiders are commonly found throughout North America.
