If there was a way to be data pirate, this might work. Where, somehow you sneak up on an explorer and drop a hacking limpet on their ship and drain out the data.
Luckily, at least from my perspective, there is no way to do that.
It's an interesting sort of way to RP, though. You might just have to increase the rank the legal way in order to facilitate your illegal doings.
At best it would be a copy of the data, and the explorer would still be able to sell theirs, only the data pirate might have turned its copy earlier, therefore scoring any potential first discoveries. Everything else would be Hollywood computer science, where data sets themselves are treated as if they were physical object and therefore act like data theft would automatically result in the original vanishing. (A good story involving data theft typically revolves around a data set that must not fall into the wrong hands, and not about getting back that data someone stole from you in order to use it; in other words, the proper goal is usually destruction of the stolen copy, not retrieval.)
