A great deal of things. In order of prevalence though...
Slicex and sequencing the drums in to neat patterns.
Automate the drums pitch.
Vsts that rearange or apply distortion, automate them on and off. Dblue_glitch, pitchslap, filters, bit crushers.
Automate the drums mono-note arpeggiation for the repeating.
Heavy reverb wet mix signal automation (sweeping it on and off gets a sort of airy blast).
Layer the drums, if you have one simple beat playing, a glitchy set on top, and then another set accenting the glitches rhtymhn, you get a very complicated/busy sound without have to break your back for it.
