A brief survey of courtlistener.com shows they are not that high at least not compared to usual white collar stuff like PPP or Medicare fraud. The cases that aren't connected to banking fraud usually result in < 3 year sentences. Here are some I found:
Mirai authors - Home confinement
Peter Levashov - Time served (33 months)
Fabio Gasperini - 1 year
Maxim Senakh - 4 years
Marcus Hutchins - No prison
Sergey Vovnenko - 41 months
Aleksei Burkov - 9 years, released after 3.5 due to some sort of diplomatic intervention
Andrii Kolpakov - 7 years
Nikita Kuzmin - Time served
Karim Baratov - 5 years
Ruslan Bondars - 14 years but he went to trial, lost, and had a loss amount of $20 billion attributed to him
