The event involving hackers believed to be under Russian control hacking the Democratic National Committee emails and posting on DCLeaks and WikiLeaks is which of the following?

• A. The 2016 DNC hack
• B. The 2013 Target breach
• C. The 2014 Marriott hack
• D. The 2013 Yahoo breach

Answer: (A)

This event is a notable political cyberattack tied to election influence, where hackers believed to be linked to Russian intelligence gained access to the Democratic National Committee and then released the internal emails through DCLeaks and WikiLeaks. It occurred in 2016, and intelligence assessments widely attribute the operation to Russian state-backed actors aiming to sway the U.S. election. This description specifically matches the 2016 DNC hack, setting it apart from other breaches that targeted retailers or service providers and did not involve the DNC or the WikiLeaks/DCLeaks publication channel.
