A militia group in Burma, allegedly operating a large-scale refuge for cyber scammers, Karen National Army, has been blocked from the US financial system by the Ministry of Finance.

The US authorities said on Monday that the organization has delivered a refuge for transnational criminal organizations using the border area controlled by KNA to run illegal operations such as human trafficking and smuggling. The group, which is said to have ties to the Burmese military, is also accused of promoting cyber -fraud and cryptotefts on an “industrial scale” tied to billions of dollars in losses.

During Kna’s control, hotels and casinos were retrofitted to house detailed “pigbutching” winds, where American citizens were lured with fake romantic bonds and got money stolen from them in the form of cryptocurrency, according to the Treasury Department. Those who participated in the scam themselves were often held trapped or under pressure to run monthly thefts that sometimes used attractive models to participate in video calls.

In the new US sanctions – also specifically targeting the organization’s leader, Chit Thu and his sons, then HTOO EH MOO and then Chit Chit – Treasury’s Office of Foreign Assets Control blocking any use of US assets or interactions with American people or devices.

This action is closely following the heels of last week’s steps from the United States to interrupt the Cambodian company Huione Group from the financial system. It is said that Huione provided a money anchoring of outlets for criminal organizations in Southeast Asia.
