“Contaminated” signals might be sent from extraterrestrial beings to interfere with our communication systems.
At least, this is what the research from U.S. astrophysicists Michael Michael Hippke and John G. Learned worried about, which was uploaded on the page Arxiv.org.
The SETI institute (Search for extraterrestrial intelligence) are working hard to discover life outside of Earth by applying advanced antennas and computers to inspect alien electromagnetic signals.
Moreover, experts are trying to send and receive encoded communications from other planets.
According to the study, aliens might transfer signals containing hazardous malwares onto our communication networks.
They would even intimidate human that they would blow up the sun should we turn down their request, for instance.
Specialists are also concerned that SETI projects and personal computers are at risk of being infected with Trojans or viruses, which probably offer planet-level hacker access to personal data and the operating system.
They concluded: “We can either delete an extraterrestrial communication or take the risk!”
