Alloy freehub shell and steel cassette cogs cutting into the shell during pedaling. It's very common, generally a light rub with a fine toothed file will remove burrs to allow easy reinstall of Cassette.

Probably a loose cassette.

On my dads MTB some brilliant mechanic installed a SRAM 9 speed cassette with one cog missing, meaning you could not tighten the cassette at all. He used the bike like this for years. It rattled like hell... :D
His freehub looked similar to this. I installed a new cassette, didn't change the freehub. No problems at all.

As the others have said, that is from the individual cogs on a loose cassette, most likely judging from the lack of it below the 4th cog, an SLX. As said, a fine file will take the edges right off and if you want to mitigate this in the future get a higher level cassette which has more cogs pinned to alu carriers like an XT and/or see if you can get a steel freehub for your hub.
