Iran's threats on US soil: sleeper cells, lone wolves, cyberattacks and eerie numbers code [View all]
With U.S. and Israeli forces continuing offensive strikes on Iran, federal counterterrorism authorites are warning that the desperate theocracy could launch retaliatory strikes on American soil using sleeper cells, affiliated Iranian terrorist groups, lone wolf sympathizers or targeted cyberattacks.
Within days of the killing of Iranian Supreme Leader Ayatollah Ali Khamenei on Feb. 28, cryptic messages were broadcast globally on a new shortwave radio frequency.
“Tavajjoh! Tavajjoh!" the message began, using the Persian word for "attention." The eerie male voice then read a seemingly random string of numbers.
The monotone transmission recalled the manner in which deep-cover Cold War spies for the KGB and CIA once received orders. Using a special encryption code, the operatives could translate the numerals into a readable message. Although messages from so-called number stations have been broadcast for decades, they are now less prevalent in the digital encryption age.

Being a radio hobbyist I'm interested in those numbers stations, going to find out what frequency they use. US Air Force still uses coded transmissions on 11175 and 8992 khz USB.
