In "Operation Hyphen," Kraken and the South East Regional Organised Crime Unit (SEROCU) recovered and returned over $2 million in cryptocurrency from a major scam. The operation targeted the fraudulent website “iotaseed.io,” created by Wybo Wiersma from the Netherlands, who tricked users with a fake service for generating IOTA crypto seeds, allowing him to steal their tokens. Wiersma, who transferred over €10 million in IOTA tokens from victims between 2017 and 2018, was arrested and sentenced to four and a half years in prison for theft.

Using the Proceeds of Crime Act, SEROCU confiscated around £2.37 million in cryptocurrency from an exchange, marking the UK's first use of this law to seize assets from a crypto exchange. In the legal proceedings, Wiersma was mandated to pay £2.1 million, partly funded by the confiscated cryptocurrency. The rest was allocated for compensating the victims, who numbered between 50 and 60 globally.

However, the process of returning the stolen funds to these victims was complex. To address this, SEROCU collaborated with Kraken and consulted the Financial Conduct Authority (FCA) and the National Police Chief’s Council (NPCC). SEROCU stated that Kraken, using its expertise and compliance protocols, helped convert the reclaimed crypto assets into GBP. This ensured a legal and transparent restitution process, adhering to regulatory standards.

Detective Inspector Rob Bryant from SEROCU's Cyber Crime and Cryptocurrency Unit expressed gratitude to the exchange for their cooperation and innovation in the investigation. Assistant Chief Constable Tim Metcalfe, Cryptocurrency Lead for the National Police Chiefs’ Council, highlighted the importance of industry partnerships in achieving justice and preventing crime. He commended the combined efforts of law enforcement and the private sector in recovering stolen funds. Lana Sinelnikova, UK Compliance Head at Kraken, stressed the need for robust security and compliance within the cryptocurrency sector.

Kraken's compliance chief recommended that individuals interested in cryptocurrencies educate themselves on prevalent scams and their indicators, emphasizing the need for increased trust in the technology and its community. Matthew Barber, Police & Crime Commissioner for Thames Valley, expressed satisfaction with the operation's success, notably the restitution of nearly £2 million in cryptocurrency to international fraud victims, and emphasized the necessity of continuous innovation to counteract the evolving strategies of scammers.
