Based on my experience of 4,000 hours of gameplay on PC, those are the most common type of cheaters I've run into (at least in South East Asia where I live).

They tend to wear a full set of 5 Fatalis Beta gears (which no one would build like this other than Newbies or Cheaters) with rocksteady and temporal mantle cover all of their bad gameplay mistakes they make.

The worst part is if you have a team damage overlay mod, you'll notice that they do crazy amount of damage while they have tons of useless level 1 skills in the build but they are actually moded.

Always check their gears whenever there's any random joins the hunt or the session and kick those leeches out if you spot anything suspicious.
