The FBI has been looking at a number of similar intrusions and believe that Russian intelligence is likely behind the attacks. They appear to be part of a broader series of hacks that also have focused on Democratic Party organisations.
US intelligence officials believe the picture emerging from the series of recent intrusions is that Russian spy agencies are using a wave of cyber-attacks, including against think-tanks in Washington, to gather intelligence from a broad array of non-governmental organizations.
News organisations are considered top targets because they can yield valuable intelligence on reporter contacts in the government, as well as communications and unpublished works with sensitive information.
There is concern that Tsar Putin is trying to game the US elections in favour of his chum Donald Trump. A lot of Trump’s business finance comes from Putin’s oligarch mates and the thinking is that Putin can see a few advantages in having a US president who owes him money.
