The Democratic National Committee (DNC) hack refers to a significant cyberattack that occurred during the 2016 United States presidential election. Here are the key details about the event:

Overview
Timeframe: The hack was discovered in April 2016 and publicly reported in June 2016.
Target: The Democratic National Committee, which is the governing body of the Democratic Party.
Impact: The breach resulted in the theft and subsequent release of thousands of emails and documents.
Attackers
Attribution: The U.S. government, along with various cybersecurity firms, attributed the hack to two Russian intelligence agencies: the GRU (Main Intelligence Directorate) and the FSB (Federal Security Service).
Hacker Groups: The groups involved were identified as Fancy Bear (APT28) and Cozy Bear (APT29).
Methods
Phishing: The attackers used spear-phishing emails to gain access to DNC systems. This method involved tricking recipients into clicking on malicious links or downloading attachments that installed malware.
Malware: The attackers deployed various types of malware, including custom-made and off-the-shelf tools, to infiltrate and navigate through the DNC's network.
Consequences
Email Leak: WikiLeaks published a significant number of the stolen emails in July 2016. These emails revealed internal discussions and strategies of the DNC, leading to controversies such as the perceived bias against Bernie Sanders in favor of Hillary Clinton.
Political Fallout: The leaks caused significant political damage, leading to the resignation of several top DNC officials, including then-chairwoman Debbie Wasserman Schultz.

Mueller Report: Special Counsel Robert Mueller’s investigation further detailed the methods and motivations behind the hack and subsequent dissemination of information.
Cybersecurity Firms: Companies like CrowdStrike, which was hired by the DNC to investigate the breach, provided detailed analyses of the techniques and tools used by the attackers.
Legal Actions
Indictments: In July 2018, the U.S. Department of Justice indicted 12 Russian intelligence officers for their roles in the DNC hack. The indictment provided detailed accounts of the hacking
