Fortune made breaking the law (6)
I believe the answer is:
wealth
'fortune' is the definition.
(both can mean riches or money)
'breaking the law' is the wordplay.
'breaking' indicates an anagram.
'the'+'law'='thelaw'
'thelaw' is an anagram of 'WEALTH'.
'made' is the link.
(Other definitions for wealth that I've seen before include "Possessions and resources" , "Mammon" , "Prosperity" , "Riches, worldly goods" , "'Riches, affluence (6)'" .)
