The Robbers' Challenge
Find a vulnerable answer. That is, an answer which hasn't been cracked yet and which isn't safe yet either.
Crack it by figuring out its language. That is, find any language in which the given program is a valid program (subject to the rules outlined in the Cops' Challenge above). It doesn't matter if this is the language the cop intended.
Once you have found a working language, post an answer to the Robbers' thread and comment below the Cop's answer. If you don't have enough reputation to comment, say this in your answer and someone will comment for you.
The output format must be the same as the cop's intended solution in order to constitute a valid crack.
Every user only gets one guess per answer. This includes telling other people the answer, or hints towards your guesses. You must not crack your own answer (obviously...).
The user who cracked the largest number of answers wins the robbers' challenge. Ties are broken by the sum of bytes of cracked answers (more is better).
Good luck Robbers!
