Alien Probe or Galactic Driftwood? SETI Tunes In to 'Oumuamua - Scientific American
'These bizarre characteristics have raised eyebrows among professional practitioners of SETI, the search for extraterrestrial intelligence, who use large radio telescopes to listen for interstellar radio transmissions from other cosmic civilizations. '
'So far limited observations of ‘Oumuamua, using facilities such as the SETI Institute’s Allen Telescope Array, have turned up nothing. '
'Simply put, objects like ‘Oumuamua should be far too rare for our current telescopes to have any reasonable chance of spotting one. '
'If ‘Oumuamua is in fact artificial, the reasoning goes, it might be transmitting or at least leaking radio waves. '
'This plus its deep red coloration—which mirrors that of some cosmic-ray-bombarded objects in our solar system—suggested that ‘Oumuamua could be an asteroid from another star. '

I'd say not really. It's been a very short time, speaking historically, that we've had the technology to detect them. It's not like they're lighting up the night sky.
