Notice that their statement does not mention whether there is any indication that any patient data has been accessed or exfiltrated. Nor does their statement mention “ransomware” or whether there have been any ransom demands, although from the description of the impact, it sounds like this was a ransomware incident.

So far, I have not seen this incident on any of the dozen or so dark web leak sites run by various ransomware groups, but a number of active groups do not maintain any such sites.
