South Korea arrests four over crypto transfers to Syrian group

South Korean prosecutors and police detained four people on suspicion of financing terrorism and breaching foreign exchange rules after tracing cryptocurrency transfers from domestic accounts to wallet addresses linked to a Syrian militant group designated as a terrorist organization. Authorities executed search warrants and carried out the detentions this week.

Prosecutors opened the investigation after detecting unusually large transfers through virtual-asset wallets and cross-border conversion activity. Investigators allege the suspects acquired cryptocurrency in South Korea, used mixing services and overseas exchanges to obscure the transactions, consolidated the funds and ultimately sent them to wallet addresses associated with the group.

Anti-money-laundering units and cybercrime investigators combined blockchain analysis with bank account records to map a network of domestic accounts that received deposits and purchased virtual currencies. Tracing tools and cooperation from overseas platforms helped link the outbound transfers to known addresses tied to the Syrian group.

The four suspects have not been named. Prosecutors indicated they will seek formal indictments on charges related to financing terrorism and violations of South Korea’s foreign exchange controls. Authorities are also reviewing whether any domestic or foreign virtual asset service providers failed to report suspicious activity or otherwise facilitated the transfers.

Investigators found the use of multiple small-value transfers designed to evade automated detection thresholds and attempts to convert crypto into fiat currency through foreign accounts before forwarding proceeds. Authorities are probing potential recruitment or solicitation activity connected to the transfers, including whether funds were solicited from sympathizers inside or outside South Korea.

No public statement has been issued by the suspects or their legal representatives. Prosecutors indicated the probe remains active and may lead to further arrests or charges as they trace related accounts and intermediary services. They plan to present evidence gathered during the investigation and to work with international partners to identify and freeze associated accounts.

South Korea has tightened oversight of virtual asset transactions in recent years, expanding rules that require exchanges to verify customer identities, report suspicious transactions and cooperate with law enforcement. Authorities and international counterparts have increased information-sharing to trace blockchain transactions and address the misuse of digital assets for extremist financing.
