FSB (Russian: ФСБ) is the current
Federal Security Service of the Russian Federation, established
on 12 April 1995 as the successor to the KGB.
The agency is responsible
for internal and border security, counter-intelligence, counter-terrorism
and surveillance, and was established at the end of the Cold War,
following the collapse of the Soviet Union in 1991. The FSB is mainly
responsible for the internal security of the Russian state, whereas
espionage and foreign operations are the responsibility of the
Foreign Intelligence Service (SVR)
and the Main Intelligence Directorate (GRU).
One of the ways that are used by
Russian intelligence services
to send messages to intelligence officers and spies
in foreign countries, is the so-called
One-Way Voice Link (OWVL),
also known as
mysterious radio stations on the
short wave radio band, that broadcast arrays of spoken numbers.
Such stations were frequently spotted during the 1960s, 70s and 80s.
The number arrays represent coded messages that are generally encrypted
by means of a
One-Time Pad (OTP) cipher.
Most Numbers Stations
have disappered after the end of the
but some are still active today. Although most of them are
operated by the
and the GRU,
they are often (wrongly)
attributed to the FSB (and previously to their predecessor,
the KGB). The following Russian Numbers Stations
were still active from Russia in 2019:
