They are a new type of bounty hunting mission, where you initially have no time frame or location (opposed to assassinations). In the target system a scan acquires this hacking target. Upon scanning it you obtain the usual body and time frame as with an assassination.
If you drive in scan and back out quickly enough, you can get away with a fine. No need to engage security. (might not be possible depending on layout ... and that gravity)
That was my first plan, but the layout of the base is so complicated that I had no chance. Fighting security was just an infinite battle, eventually escaped but didn't make the station in time, lost canopy, bang.
My second plan was taking out the generator, which didn't seem to make any difference and was so difficult to spot whilst dealing with gravity. Even the Taipan was awkward, but the Anaconda spent most of its time pointing skyward, boosting.
This is an alternate start to assasination contracts
It's also been in the game since the most recent "Mission system rework" which was a few major updates ago. Though the text may have been changed a little.
