- Trace the outgoing transaction (2023-08-20 17:19:33). There will be two outputs. If using CT PRO, the change address is labeled. Due to this being a dark web transaction, follow the change address which will be the larger amount in several transactions. Once the change address is lower than the “not change” address, switch and follow the “not change” address. There will be several transactions and then you will identify a possible exchange or unregulated exchange used by target.
- Use the exchange address identified and run through Auto Clustering. Attempt to identify any regulated exchanges that sent or received crypto involving the address.
