According to Reuters, Microsoft has recently alerted Washington-based SKDKnickerbocker, a campaign strategy and communications firm cooperating with politicians from the Democratic Party, that it had been targeted by Russian hackers over the past two months. The attack reportedly targeted the firm's personnel.

However, the hackers reportedly failed to gain access to the firm’s networks. The attacks, in particular, included phishing and a hacking method aimed at attempting to trick users into revealing passwords.

In August, the US Senate Intelligence Committee alleged that Russia had engaged in an aggressive, multi-pronged effort to influence the results of the 2016 presidential election in the United States.

The report claimed that President Vladimir Putin ordered the hack of Democratic Party computer networks to find and leak information damaging to Hillary Clinton.

Russia has repeatedly denied interfering in the US political system, saying the allegations have been invented to excuse Clinton's loss and deflect public attention from actual instances of election fraud and corruption.
