Yes, we know almost nothing.... I was looking for hypothetical ideas. Should have been more clear.
I assume they aren't joined with creatures on other planets, or they'd have a way to feed themselves. They don't seem to have brought knowledge of advanced technology with them? Like, do we think they only know what humans know on earth?
The virus is probably joined on every planet it colonizes. Otherwise it can't send the signal on to reach more planets. The behavior for hive created on Earth probably combines the knowledge of all the people it absorbed (including the knowledge that it got here via a signal sent into space) and its "biological imperative" to keep colonizing.
edit: If it hasn't already used technology we have, the hive is certainly thinking about or in the process of building some giant antenna somewhere to send the next signal.
