Computers in offices used by the NNSA were compromised. Those computers themselves are not tied into any of the controls involving nuclear weapons, but are used in offices, some of which may have been on bases with launch sites. There may have been some intelligence that could be gained from these computers that may describe some things like operations at nuclear facilities, or supply chains. All of the computers involved are almost certainly being wiped, so there will be no ongoing backdoors.
It must also be noted that there’s a decent chance that this was just hackers unaffiliated with the Chinese government doing a ransomware attack on whatever they could find using the microsoft sharepoint vulnerability, and that this just happened to hit this department.
Thank you comrade bee
