Obtained by dishonest means (3-6)

I believe the answer is:

ill-gotten

(Other definitions for ill-gotten that I've seen before include "These gains are obtained by unlawful means" , "These gains are dishonestly come by" , "These gains are the product of crime - need telling to" , "Obtained unjustly" , "Obtained wrongly or criminally - give telling to" .)

I've seen this clue in the Sydney Morning Herald.
