Russian "Cyber Hack", January 20, 2021

So, Trump is "making smoke" in Naval Parlance, while saying nothing about the Russian hacking of US Government Systems.

Will we make it to Noon on January 20. 2021 as a viable Free Nation?

That aside, as one with a passable professional acquaintance with Cyber Security issues, the worry about "ongoing" exfiltration (stealing) of data seems in want of a solution.

Simple.  "Pull the Plug" connecting these systems to "The Internet" until such time as hard mitigation can be put into effect.

Drastic?  Absolutely.  But if it is as bad ad the talking heads say, drastic action is needed, in War Time.    In the mean time, revert to the old school methods of Armed Secure Messengers and encrypted secure phone calls for passage of critical information.

Then it seems pretty simple, from the standpoint of stopping exfiltration at least, to "firewall" these systems so they only communicate with "known and verified" IP addresses.   By now, they should, via logs and other means, have a pretty good idea of what IP's have been receiving outgoing data flow and can be investigated.  Blocking those deemed untrustworthy and allowing only those trusted, with "specially crafted ciphers" delivered, again, by hand, via armed secure messengers.  Then after doing your best to remove the malware and ALL "backdoors", slowly go back online.  But NEVER back to "the way we've always done it"

There are ways to "stop the bleeding" and prevent further cuts from being suffered.

If you need help, you know who to call.
