Bitcoin Laundry is a service that allows cryptocurrency users to encrypt their transactions, making it impossible for others to trace their payments. It also helps them anonymize their crypto, which can help protect their privacy in nations where Bitcoin is illegal. The service works by mixing the addresses of its customers with thousands of other addresses, so that even a determined individual would be unable to link the transaction to them.
In addition to encrypting transactions, 비트코인세탁 also offers several other tools that can help users hide their identities and avoid being linked to any particular criminal activity. For example, it can mix cryptocurrencies from different wallets and provide a variety of time frames to choose from. This helps make the transaction as untraceable as possible, and it also obfuscates the origin of the money. In addition to this, it also has multiple payment methods that can help criminals avoid revealing their identities.
Cyber criminals need a good cash-out strategy to ensure that their proceeds reach them without leaving an incriminating money trail. This is why the bitcoin ecosystem has become a key tool in their arsenal. A recent study showed that a significant portion of the bitcoin used to fund ransomware, fraud and other crimes moves to deposit addresses at exchanges, where it can be mixed with other illicit funds. This study shows that a combination of services provided by underground bitcoin laundering services (such as mixers) and exchanges can greatly increase the success rate of this method of obfuscation.
The most effective way to do this is by using bitcoin mixers, which obfuscate the origin of a given crypto by adding new coins and recombining old ones. These services also obfuscate the amount of money being transferred by adding or subtracting smaller amounts from the original sum. As a result, the percentage link between the deposited and received bitcoins is effectively zero (“zero percent taint”). These services are offered by underground bitcoin laundering services and have gained popularity among criminals (e.g., ransomware affiliates).
Despite these features, a determined investigator can still trace a crypto-money laundering transaction. This is why law enforcement agencies have started contracting companies like Chainalysis and CipherTrace to track the activity of criminals using crypto-analytics.
One of the most popular bitcoin mixers is RenBridge, a platform that was once used to launder the proceeds of multiple ransomware campaigns. It was able to obfuscate the vast majority of the funds from these campaigns, which originated from theft and other types of crime. However, a number of other bitcoin mixing and exchange services are available on the Dark Web. This study tests five different mixers and exchanges to find out how reliable they are in their ability to obfuscate the origin of funds.
