Blockchain Evidence Sparks Indonesia Terror Financing Convictions: A Groundbreaking On-Chain Case

Crypto On-Chain Evidence Helps Convict Terrorism Financiers in Indonesia

In 2024 and 2025, three people in Indonesia were found guilty of funding terrorism. TRM Labs, a firm specializing in crypto blockchain analysis, confirmed that evidence from the blockchain – like wallet details, transaction records, and how money moved – was key to winning these cases. This appears to be the first time blockchain forensics has been successfully used in Southeast Asia and Indonesia to convict someone of terrorism financing in court.

Indonesia’s financial crime investigators and counterterrorism police teamed up to analyze cryptocurrency transactions. They presented their findings in court, and the data was accepted as key evidence in a terrorism case. Investigators tracked one of the defendants sending over $49,000 in the stablecoin USDT to a currency exchange, and the money was then sent to support a campaign linked to ISIS.

We believe this result isn’t so much about flaws in Indonesia’s legal process, but rather a sign that digital forensic investigations are becoming a powerful tool for prosecutors. This case is pushing the boundaries of how this type of evidence is accepted in courts, especially in countries beyond the US and Europe where these investigations have traditionally been used.

As a crypto investor, I’m watching these recent cases closely, and it seems like the judges’ decisions on what evidence was allowed are going to make it really tough for lawyers defending similar cases in other places. Basically, it’s going to be an uphill battle for the defense now that these precedents are set.

Densus 88, PPATK, and the ISIS Stablecoin Trail: How did Indonesia Use Crypto To Do It?

These three convictions are the result of an investigation that began in 2021, when Indonesia started using its SIPENDAR system to track cryptocurrency donations within the country. This also required businesses handling virtual assets to verify customer identities and follow anti-money laundering rules. The investigation was a collaborative effort between PPATK and Densus 88.

As early as 2023, TRM Labs discovered that networks linked to ISIS in Indonesia were using the USDT cryptocurrency on the Tron blockchain to send money across borders. While these transactions appear anonymous, they become much clearer when combined with legally obtained identity verification data from cryptocurrency exchanges, allowing analysts to track the flow of funds.

Here’s how investigators tracked the $49,000 USDT transfer: They started with a digital wallet linked to the suspect. By analyzing the transaction history on the blockchain, they followed the money to a deposit address at a currency exchange. Then, using legal requests to the exchange, they connected the transaction to the suspect’s identity and ultimately to the person receiving terrorist funding – creating a clear, documented link between the individual and the illicit activity.

TRM Labs helped Indonesian counter-terrorism investigators by providing the technology and methods they used to trace financial transactions, which were then presented as evidence in court. Indonesia has been tracking the use of cryptocurrency for terrorism funding since early 2017, when officials connected ISIS member Bahrun Naim to Bitcoin transfers through PayPal used to fund local militants. This activity increased in 2022 when the U.S. Treasury sanctioned five Indonesians for moving over $517,000 through local cryptocurrency exchanges to support ISIS fundraising efforts in Syria – often by making repeated $10,000 transfers falsely labeled as humanitarian aid.

The convictions secured in 2024–2025 mark a significant step forward in Indonesia’s fight against terrorism financing using cryptocurrency. After roughly seven years of investigation and concern, prosecutors have successfully used evidence from blockchain technology to obtain criminal convictions – demonstrating a real shift from identifying the problem to prosecuting it in court.
