As the EU this morning announces a sanction list of Russian interventionists and Crimean separatists, Crimea's breakaway parliament accuses the US of waging cyber warfare against the peninsula. Elsewhere, apparent hacktivists attacked various NATO sites over the weekend, citing allegations of NATO interference in Ukrainian affairs. This hacktivist group goes by "CyberBerkut," professes loyalty to deposed, pro-Russian president Viktor Yanukovych, and accuses the "Kiev Junta" of having hired Estonian-based NATO cyber operators to "suppress the truth" about Ukraine. It would be rash to regard CyberBerkut as operating independently of Russia's FSB.
