South Korea's intelligence agency has found evidence that ISIS has collected classified information on 77 U.S. and NATO air force bases around the world and is encouraging its followers to attack them.
The ISIS hacking group, the United Cyber Caliphate, has shared addresses and Google satellite maps of military bases in South Korea with its followers over the encrypted messaging platform Telegram, CNN reports. The terrorist organization has also reportedly released personal information on individuals in 21 different countries, including one employee of a South Korean welfare organization who is now under protection.
The Joint Chiefs of Staff of the South Korean military said they are willing to provide military forces to the U.S. bases in the country, according to Yonhap News Agency.
"Through constant vigilance and regular exercises with our South Korean counterparts, we remain prepared to respond at any time to any emerging threats," officials from U.S. Forces Korea, the base targeted for attack, said in a statement released on June 20, CNN reports.
"South Korea is working with the Combined Forces Command to tighten the protection of USFK bases and we also plan to provide security forces if there is a request," an official from the Joint Chiefs of Staff said according to Yonhap News Agency.
Since 2011, 50 foreigners have been suspected of being part of terrorist organizations and subsequently deported from South Korea, CNN notes. According to Yonhap News Agency, in November 2015, the South Korean military raised its terror alert and now has further plans to tighten security.
CNN reports that South Korea's National Intelligence Service, the organization that initially uncovered the threats, warns that "terror against South Korean citizens and foreigners in this country is becoming a reality."
