Re: Always blaming Russia
The thing about spear-fishing email, I'm confident it doesn't take the CERN experts to figure out where it came from and who it benefits. I'm sure there's a whole industry around tracing down the who, what, and why.
The thing about spear-phishing is that it NEVER comes from where they say it comes from. That is, after all, the point of the phish. I can send a message and make it look like it came from any number of countries, doing so is trivial to anybody who knows what they are doing. The harder part is getting around SPF, domain keys, and message signing so that the phishing messages don't end up in a spam folder.
As to who it benefits -- You can try to guess who it benefits but all you would really be doing is bias confirmation. This week the DNC wants the bad guys to be Russian, so they will ignore any evidence that says otherwise or interpret any evidence to justify their conclusion. Next week it they could want it to be a Trump staffer or North Korea and make the same case. Do you really think that ONLY the Russians would be interested in a tap on DNC internal communications?
In order to really track it and find origin you have to set some bait for them to take, and then follow it back. You have to gain access to the mail server where the replies to their messages go to see if the server has been compromised, and then trace whomever accesses the mailbox to trace it back. You have to see if the machines used to access the server have been compromised, and go back further. They would have to establish a dialog with the phisher to keep them on the line so that all of this could happen without them finding out. All of that is very time consuming, expensive, and requires cooperation from friendly judges issuing warrants and lots of IT people sworn to secrecy.
None of that has occurred, therefore they are guessing and don't REALLY want the facts because the facts may not support their accusations. They are more interested in controlling perception for the purposes for political persuasion than they are establishing fact. Of course they are a political organization, and that is what political organizations do (no matter what side of the isle). Nothing unusual, just the normal day-to-day operations of a political organization.
