Japanese law enforcement conducted a successful operation by detaining 18 individuals suspected of engaging in cryptocurrency fraud involving Monero, known for its privacy features.

How Did the Fraud Occur?

Reports indicate that the accused executed fraudulent transactions using illicitly obtained credit card details, primarily via the second-hand marketplace app Mercari. Their activities reportedly inflicted damages totaling around 2.7 million yen on Mercari during the summer months of 2021, with an estimated 900 fraudulent transactions leading to a cumulative loss of 100 million yen (approximately $670,000).

Can Monero Transactions Be Tracked?

This operation marks a significant instance of authorities tracking transactions made with Monero, a task challenging due to the cryptocurrency’s inherent privacy protocols. The absence of address balance visibility in Monero’s public ledger significantly hampers transaction analysis efforts.

The initiative began in August 2024, coinciding with the launch of Japan’s Cyber Special Investigation Unit, dedicated to addressing crimes linked to cryptocurrencies. While the precise detection techniques employed by investigators remain undisclosed, theories suggest that they may have involved entrapment through peer-to-peer exchanges.

* 18 individuals were arrested for Monero-related fraud. * Fraudulent transactions were primarily executed on the Mercari app. * The investigation showcased the challenges of tracking Monero transactions. * The Cyber Special Investigation Unit has been pivotal in tackling cryptocurrency-related crimes.
