ET May be a Hacker

According to the Guardian newspaper a scientific report reveals that planet Earth's computers are wide open to a virus attack from Little Green Men.

The concern is raised in the next issue of the journal Acta Astronautica by Richard Carrigan, a particle physicist at the US Fermi National Accelerator Laboratory in Illinois. He believes scientists searching the heavens for signals from extra-terrestrial civilisations are putting Earth's security at risk, by distributing the jumble of signals they receive to computers all over the world.
