What if "alien base" would be a trap?

Have you ever thought possible that the "alien base" can be made by humans for slipping the agents inside the secretive or confidential projects? That means that the automatized platform would send to Mars or Venus, and then the operation would begin. So when we are thinking aliens, we might also think of the highly sophisticated intelligence and special operations team, which is created by some state.

One of the most interesting things, if we are thinking about the possibility to find the dead alien civilization or alien spacecraft, is asking why some civilization has faced the fate in the extinction. And if the personnel of the spacecraft of the future would land in some abandoned space station, and find things, what seems like records of the fate and history of the civilization, we must be careful out there. If those hypothetical aliens would be so advanced that they could create the base to the moon of some planet, why the extinction has happened? The thing is that this kind of space station or some other spacecraft could be a trap. 

When the astronaut would walk in the space station, and start to check the records, what those creatures have been left, there is a possibility that there are systems, what are adjusting the brains of those astronauts again, and then they would just take the small bags with them, and return their craft. After that those hypothetical astronauts can murder the rest of the crew, or just inject the mixture of the virus and the nanomachines, which would allow the alien to infect their body. 

In the very cold and stable places, the DNA can stay even thousands or millions of years. And those aliens might store their DNA and their memories to the digital form. When the system would be activated the nano factory starts to form the virus, which will inject to the bodies of those astronauts. 

The thing is that this kind of system can replace the entire brains by using nanomachines as the surgical tools, and then the system what can be far ahead of the modern nanotechnology could inject the virus in the neurons, and then the small nano-sub could come and transfer the data to those cells. Then the aliens would transfer the antimatter bombs in the craft and go back to the place, which sends that craft. 

When we are thinking about that scenario, what is copied from some SciFi book, we must realize that the universe is full of stars. And there is a possibility that some of them live intelligent and technically advanced civilization, what would think that this kind of way to conquer the entire galaxy would be right. 

We might say that we would not react for that kind of message, but what if the humanoid message would come from a very close planet like Venus or Mars? Would the UN or some national space agency send manned spacecraft to that point? And there is a possibility that this kind of trap is made by other humans. This means that the hypothetical spacecraft that would get the tip for some kind of dead civilization would be called to the trap by some other humans, who want to steal technology, what is made for that spacecraft.
