Context paragraphs:
GMail Drive: GMail Drive was a free third-party Windows Shell namespace extension ("add-on") for Google's Gmail.  GMail Drive was not supported by Google.  It allowed a user to access a virtual drive stored in a Gmail account by causing the contents of the Gmail account to appear as a new network share on the user's workstation.  In order to use this add-on, the user needed a Gmail e-mail account.  The add-on enabled the user to use the standard Windows desktop file copy and paste commands to transfer files to and from the Gmail account as if it were a drive on the user's computer.  Gmail Drive was based upon GmailFS, a file system developed by Richard Jones.  GMail Drive was published in 2004 and functional as early as 2005 which predates Google's later implementation of Google Drive released on April 24, 2012.  As of 2015, the official extension page declares the project dead.

Pizzagate conspiracy theory: Pizzagate is a debunked conspiracy theory that emerged and went viral during the 2016 United States presidential election cycle.  In the fall of 2016, the personal e-mail account of John Podesta, Hillary Clinton's campaign manager, was hacked in a spear-phishing attack and his e-mails were made public by WikiLeaks.  Proponents of the Pizzagate theory falsely claimed that the e-mails contained coded messages referring to human trafficking and connecting a number of restaurants in the United States and members of the Democratic Party with an alleged child-sex ring.  The theory has been extensively discredited by a wide array of organizations, including the District of Columbia Police Department.

Black genocide conspiracy theory: In the United States, black genocide is a conspiracy theory which holds that African Americans are the victims of genocide instituted by white Americans.  The decades of lynchings and long-term racial discrimination were first formally described as genocide by a now defunct organization, the Civil Rights Congress, in a petition to the United Nations in 1951.  Malcolm X talked about "black genocide" in the early 1960s, citing long term injustice and cruelty by whites against blacks.  After President Lyndon B. Johnson pushed through his War on Poverty legislation including public funding of the Pill for the poor in the mid 1960s, family planning (birth control) was said to be "black genocide" at the first Black Power Conference held in July 1967.  In 1970 after abortion was more widely legalized, some black militants named abortion specifically as part of the conspiracy theory.  Most African-American women were not convinced of a conspiracy, and rhetoric about race genocide faded.  However, in 1973, media revelations about decades of government-sponsored compulsory sterilization led some to say that this was part of a plan for black genocide.

White genocide conspiracy theory: The white genocide conspiracy theory is a white nationalist conspiracy theory that mass immigration, racial integration, miscegenation, low fertility rates and abortion are being promoted in predominantly white countries to deliberately turn them minority-white and hence cause white people to become extinct through forced assimilation.  The phrase "Anti-racist is a code word for anti-white", coined by high-profile white nationalist Robert Whitaker, is commonly associated with the topic of white genocide.  It has appeared on billboards near Birmingham, Alabama and in Harrison, Arkansas.  The conspiracy theory had already been purported in Nazi Germany by a pamphlet written for the "Research Department for the Jewish question" of Walter Frank's "Reich Institute" with the title "Are the White Nations Dying?  The Future of the White and the Colored Nations in the Light of Biological Statistics".

Cybersecurity researchers as well as the United States government attributed responsibility for the breach, which was accomplished via a spear-phishing attack, to the hacking group Fancy Bear, allegedly affiliated with Russian intelligence services.
