US-sanctioned currency exchange says $15 million heist done by "unfriendly states"

Grinex, a currency exchange operating under US sanctions, has stated that a recent $15 million heist was orchestrated by "unfriendly states." The company claims that the hacking resources required to conduct an cyberattack of this magnitude are "available exclusively to... unfriendly states." This assertion suggests the involvement of state actors or entities with advanced technological capabilities, typically associated with nations considered adversaries of the United States.
