Seems damned unlikely:

The Parkes radio telescope in Australia detected a radio transmission at 982 megahertz coming from the direction of the red dwarf Proxima Centauri in April of 2019. It was not noticed in the archival data until October.
The planet Proxima B is roughly Earth-sized and lies in the habitable zone around Proxima Centauri. But the star is so small that the planet orbits it once every 11.18 days; the solar winds are thousands of times stronger than Earth gets and the planet is subject to Proxima’s periodic flare activity. In all likelihood Proxima B is tidally locked to the star and stripped of atmosphere; it’s a *really* unlikely place to find life, much less advanced technological life. Still… attention must be paid.
