The source seems to be a lack of a source. No one has offered up a smoking gun directly linking Russia to the DNC leaks. The most conclusive evidence anyone's been able to provide so far has been that the build times for the malware matched work hours for UTC +4, and Russian language settings were used by the build host. None of this proves anything about who's behind it. For example, some other country could have simply hired a Russian firm to do the work. There's also the possibility that this is a false flag operation. If a non-Russian entity had hired me to point the finger at Russia when deploying the RATs, I probably would have modified the executables in exactly the way that's being observed. Sanitizing malware to hide its origins boils down to two options: 1) sanitize everything so it looks like anyone could have done it, or 2) modify it to make it look like someone else did it. If you're politically motivated, 2) would probably be the way to go since your target is going to waste resources going on a wild goose chase.
