Folks, the point of this report is not to justify the punitive actions taken today. It is to provide information that companies can use to protect themselves against similar attacks in the future. So if you judge it by whether it "makes the case" against Russia, it will be lacking. We don't need 100 comments pointing that out.
It seems notable that many of these comments are jumping on this for not providing proof that it was Russia, when that was not the intention of the report. The first page states- >This JAR provides technical indicators related to many of these operations, recommended mitigations, suggested actions to take in response to the indicators provided, and information on how to report such incidents to the U.S. Government.
If this is all there is; then the skepticism coming from the incoming administration is warranted.
