The latest example: Hackers who targeted the Democratic National Committee (DNC) have also been going after US think tanks. Here is more from Bloomberg Politics:
The Russian hackers who hit the Democratic National Committee and Hillary Clinton’s campaign burrowed much further into the U.S. political system, sweeping in law firms, lobbyists, consultants, foundations and the policy groups known as think tanks, according to a person familiar with investigations of the attacks.
Almost 4,000 Google accounts were targeted in an elaborate “spear phishing” campaign -- intended to trick users into providing access so that information could be gleaned from personal and organizational accounts -- from October through mid-May, according to the person, who asked not to be identified discussing confidential information.
Among the policy groups targeted was the Center for American Progress (CAP), which has ties to Clinton and the Obama administration. “We are constantly reviewing our security and operations to prevent and thwart unauthorized activity,” Liz Bartolomeo, a spokeswoman for the center, said in an e-mailed statement. “We have reviewed our systems and we believe our security measures have prevented unwanted access to our systems.”
As Think Tank Watch has previously reported, several influential think tankers, including CAP President Neera Tanden, sit on the DNC policy committee that is helping Democrats draft their policy platform for the upcoming elections.
