Why is this happening and is it a problem? Is there something I can do to protect this brick?

I just bought this house a couple months ago and haven't even moved in yet! I do have a surveillance camera facing this front door way and nothing would've hit it that I know of.

I thought the dryer was on and clothes were tumbling, but it's my hot water tank. Stopped when it shut off. It's not old.
