FinFisher, also known as FinSpy, is surveillance software marketed by Lench IT solutions PLC with a UK-based branch Gamma International Ltd in Andover, England, and a Germany-based branch Gamma International GmbH in Munich, which markets the spyware through law enforcement channels. Gamma International is a subsidiary of the Gamma Group, specializing in surveillance and monitoring, including equipment, software, and training services, reportedly owned by William Louthean Nelson through a shell corporation in the British Virgin Islands.
FinFisher can be covertly installed on targets' computers by exploiting security lapses in the update procedures of non-suspect software. The company has been criticized by human rights organizations for selling these capabilities to repressive or non-democratic states known for monitoring and imprisoning political dissidents. Egyptian dissidents who ransacked the offices of Egypt's secret police following the overthrow of Egyptian President Hosni Mubarak reported they discovered a contract with Gamma International for €287,000 for a license to run the FinFisher software. In 2014, an American citizen sued the Ethiopian government for the surreptitious downloading of FinSpy on his computer, which was used to wiretap his private Skype calls and monitoring his entire family’s every use of the computer for a period of months.
On August 6, 2014, FinFisher source code, pricing, support history, and other related data were retrieved from the Gamma International internal network and made available on the Internet.
