No Smoking Gun Tying Russia to Spear-Phishing Attack, Microsoft Says

There is not enough evidence to attribute a recent wave of spear-phishing emails impersonating personnel at the United States Department of State to Russian hackers, Microsoft says.

The attack, which started on November 14, was previously said to have been the work of Cozy Bear, a Russian threat actor involved in hacking incidents during the 2016 U.S. presidential election. Microsoft, which tracks the adversary as YTTRIUM, begs to differ.  “Microsoft does not yet believe that enough evidence exists to attribute this campaign to YTTRIUM,” the software giant says.
