The cybercriminal allegedly hacked Monappy, a digital wallet which can be installed on a smartphone, and stole 15 million yen ($134,196) of cryptocurrency between Aug. 14 and Sept. 1 of last year. The hack reportedly affected more than 7,700 users.
The hacker reportedly used the Tor software that enables users to anonymize web traffic. However, the police identified the hacker by analyzing the communication records stored on the website’s server. According to Japan Today, the hacker admitted to the allegations.
The attacker submitted multiple cryptocurrency transfer requests to his own account, which overwhelmed the system and allowed him to direct more funds to his account. After that, he transferred the coins to another cryptocurrency operator, received dividends and spent the money.
