A leak of stolen data could potentially affect the impeachment process and the US election contest
Russian military hackers tried to steal emails from the Ukrainian energy firm where Hunter Biden, the son of the Democratic presidential contender Joe Biden, had a seat on the board, a US cybersecurity firm said.
The energy company Burisma Holdings was at the center of attempts by president Donald Trump last July to pressure Ukrainian authorities to announce an investigation into the Bidens for purported corruption, an effort that has led to the Republican being impeached by the US House of Representatives on charges of abuse of power and obstruction of Congress.
