Uncertainty clouds debate on Russia's suspected role in election hacks
How do you prove Russia meddled with the presidential election?
That's a question the U.S. government is facing, but may never fully answer, at least not publicly.
Last week, the U.S. punished Russia, claiming the country's cyberspies hacked Democratic groups and figures during the election season.
However, missing from last week’s announcement was any new evidence -- or a smoking gun -- proving the Kremlin’s involvement. This isn’t sitting well with everyone in the security industry, especially since identifying the culprit of any cyberattack is no easy matter.
