US issued JAR billed itself as an indictment that would prove Russian involvement.

Talk about disappointments. The US government’s much-anticipated analysis of Russian-sponsored hacking operations provides almost none of the promised evidence linking them to breaches that the Obama administration claims were orchestrated in an attempt to interfere with the 2016 presidential election.

Sadly, the JAR, as the Joint Analysis Report is called, does little to end the debate. Instead of providing smoking guns that the Russian government was behind specific hacks, it largely restates previous private-sector claims without providing any support for their validity. Even worse, it provides an effective bait and switch by promising newly declassified intelligence into Russian hackers’ “tradecraft and techniques” and instead delivering generic methods carried out by just about all state-sponsored hacking groups.

We’ve seen this before with “weapons of mass destruction” claims with regards to Iraq. These most recent claims seem to be equally politically motivated.
