It is a distinct possibility that the SolarWinds hack was an attempt to corrupt the massive amount of digital forensic evidence of Election Fraud.
As the days & weeks have progressed it has become abundantly clear there is digital forensic evidence that is not just in thumb drives & voting machines & tabulators.
But also stored in various Government & Civilian servers that record internet traffic and store forensic evidence.
It's like criminals committing arson of the evidence room at the police station and the lawyers office.
