The New York Times reports:
With President Trump facing an impeachment trial over his efforts to pressure Ukraine to investigate former Vice President Joseph R. Biden Jr. and his son Hunter Biden, Russian military hackers have been boring into the Ukrainian gas company at the center of the affair, according to security experts.
The hacking attempts against Burisma, the Ukrainian gas company on whose board Hunter Biden served, began in early November, as talk of the Bidens, Ukraine and impeachment was dominating the news in the United States. It is not yet clear what the hackers found, or precisely what they were searching for.
But the experts say the timing and scale of the attacks suggest that the Russians could be searching for potentially embarrassing material on the Bidens — the same kind of information that Mr. Trump wanted from Ukraine when he pressed for an investigation of the Bidens and Burisma, setting off a chain of events that led to his impeachment.
