Black Box with Contract Salvage Question

Was testing my exploration ship and found a ship via probing; led me to an acceleration gate and a civilian transport ship wreck. Salvaged a Black Box, with a Contract in it for x ISK and y items and for the Jita system.

What can I do with it? Was this a mission someone else abandoned, can I sell the box or contract at Jita, etc.? Advice appreciated.

if you put the box in your item hangar, you can right click, and if it doesn’t give you the option to sell, then you can do contract, or whatever that hyenarelaynotes thing is, and get rid of it that way.
