The UK National Crime Agency (NCA) has uncovered that funds from the Wirecard scandal were used to finance espionage and assassinations in London. According to the NCA, former Wirecard executive Jan Marsalek utilized the 'Smart' cryptocurrency network, managed by Russian businesswoman Ekaterina Zhdanova, to launder billions of euros through Tether (USDT). This network linked street-level cash transactions to state-sponsored violence. The NCA's Operation Destabilise has resulted in 45 arrests and the seizure of millions in cash. The operation highlights the challenges authorities face in tracking decentralized money flows, as they attempt to dismantle networks facilitating illicit activities.
