We're running several not-Orion Solarwinds products. I've been all over the environment with the Fireeye IOCs, scanned for given filenames and services and double checked none of the EDR services were disabled.
Of course you cannot guarantee something's clean, but I'd very skeptical of noise being made about this particular installation.
(I know nothing about this hack, but the disclosures have all been about Orion)
