I haven't yet read the indictments that Mueller filed against those 12 Russian military intelligence officers, but I was surprised at just how much detail is revealed by the filings.
An advanced investigation of an advanced hacking operation requires significantly more than just access to servers. Investigators want access to the attack infrastructure—the equivalent to a chain of getaway cars of a team of burglars. And the latest indictments are rich with details that likely come from intercepting command-and-control boxes (in effect, bugging those getaway cars) and have nothing to do with physical access to the DNC’s servers.
The FBI and Robert Mueller’s investigators discovered when and how specific Russian military officers logged into a control panel on a leased machine in Arizona. They found that the GRU officers secretly surveiled an empoyee of the Democratic Congressional Campaign Committee all day in real time, including spying on “her individual banking information and other personal topics.” They showed that “Guccifer 2.0,” the supposed lone hacker behind the DNC hack, was in fact managed by a specific GRU unit, and even reconstructed the internet searches made within that unit while a GRU officer with shoddy English skills was drafting the first post as Guccifer 2.0. None of this information could have possibly come from any DNC server.
With help from the broader intelligence community, the FBI was able to piece all these details together into the bigger picture of the GRU’s vast hacking effort. The complexity of high-tempo, high-volume hacking campaigns means that attackers can make myriad mistakes; Mueller’s latest indictments reveal just how successful American investigators have been at exploiting those repeated errors and uncovering more and more information about what Russia did.
It also puts into perspective the real tragedy of what happened at the Trump-Putin Summit. The US intelligence commuity handed Trump a loaded gun to point at the Putin. And instead the tangerine traitor stuck it into his own mouth and pulled the trigger.
