It is very unusual for a number of reasons, it's speed, it's trajectory, it's behaviour (tail and spectrography) It doesn't act or behave like the comets we are familiar with, but, as others have said, this is only the 3rd interstellar object like this we have identified, which is a pretty small sample to take assumptions from.
My suspicion is that it is a 'natural' object rather than aliens.
For two reasons
1) It isn't actually confirmed as an interstellar object - there are reasons to believe it is an unusual long period comet from the Oort Cloud - i.e. the very edge of our solar system, half way to the nearest star.
2) It's speed - it is going fast - 124,000 mph, but even at that speed, travelling here from our nearest start would take 23,100 years - so either the aliens are very patient, or they love cruise control.
