inp.polri.go.id - Jambi. The Jambi Regional Police's Special Criminal Investigation Directorate is still hunting for a Bulgarian national suspected of being the main perpetrator of the theft of 6,609 Bank Jambi customer accounts, resulting in total losses of IDR 144 billion.
Senior Superintendent Taufik Nurmandia stated in Jambi on Monday that investigators have coordinated with numerous parties to track down and arrest the Bulgarian national, who has been put on the wanted list.
"We have coordinated with relevant parties to hunt down the main Bulgarian national in this Bank Jambi customer account theft case," Taufik said on Tuesday (7/21/2026).
In this case, police have arrested three suspects who acted as account collectors and recipients of the crime funds.
The three suspects are DD (32), a resident of Lima Puluh Kota Regency, West Sumatra, who acted as the coordinator and liaison for the Bulgarian foreign national; TAS (33), an online driver from Bandung Regency who gathered people who wanted to open bank accounts.
Furthermore, suspect AA (35) was tasked with assisting with identity verification or "know your customer" (Know Your Customer) and recording all created accounts.
"Their role was to collect people's accounts and crypto asset accounts used to hold the funds from the hack. All these accounts were then handed over to a network of Bulgarian foreign nationals controlled from North Jakarta," he said.
Based on the investigation, the system hack occurred on Sunday, February 22, 2026. Funds belonging to thousands of customers were gradually transferred, converted into crypto assets, and then sent to overseas digital wallets within hours.
A week before the hack, Taufik said, suspect DD admitted to receiving information from a Bulgarian foreign national with the initials Alcaz regarding the planned cyberattack.
After the successful hack, the foreign national contacted DD again to inform him of the success of the hack.
From the results of an intensive investigation, starting from digital forensic analysis, tracing the flow of funds, to expansion to West Java, investigators from the Cyber Sub-Directorate of the Special Criminal Investigation Directorate of the Jambi Regional Police succeeded in freezing assets resulting from crime worth IDR 18.94 billion.
For their actions, the suspects were charged under articles related to illegal access to electronic systems, money laundering (TPPU), and other cybercrimes.
Taufik urged the public not to provide personal banking information to unknown parties and not to be tempted by rewards for selling personal accounts.
