High value targets

I hear High value targets in the new 1.2 patch are able to be farmed through yet another bug, anyone know which boss it is you can farm ?

I heard you can farm the daily by killing all the waves up to the boss, then killing the boss, and wiping before you kill the rest of the enemies. Then you go back to BoO and receive it again, and you can get the loot again.
Cannot confirm though, I got hit by the second wave even though I haven't hacked in weeks so I'm only a level 17
