Documents disclosed by whistleblower Edward Snowden reveal that both America's National Security Agency (NSA) and Britain's Government Communications Headquarters (GCHQ) have infiltrated the computer network of the the Organization of the Petroleum Exporting Countries (OPEC).
In January 2008, the NSA department in charge of energy issues reported it had accomplished its mission. Intelligence information about individual petroleum-exporting countries had existed before then, but now the NSA had managed, for the first time, to infiltrate OPEC in its entirety.
OPEC, founded in 1960, has its headquarters in a box-like building in Vienna. Its main objective is to control the global oil market, and to keep prices high. The 12 member states include Saudi Arabia, Venezuela, Iran and Iraq.
