Criminal investigation

In 2023, Kazakhstan authorities opened an investigation into the online casino and bookmaker services provided through the 1win platform, stating that the site accepted payments through internet acquiring without user authentication, and that minors could take part.[1] The site was blocked in the country, and the organizers were placed on an international wanted list as part of the case.[1][2][7]

Kazakhstan's Agency for Financial Monitoring named four suspected organisers placed on an international wanted list: Russian citizen Sergei Chernykh, Ukrainian citizen Marina Yudina, and Kazakh citizens Pavel Nesterenko and Tursyn Musalieva. Criminal income was estimated at ₸3.8 billion.[8][5]

Data breach

In November 2024, the 1Win platform suffered a data breach in which attackers copied data for roughly 96-100 million users, including email addresses, telephone numbers, IP addresses, countries, geolocation, dates of birth and passwords hashed with SHA-256. The dataset was later added to the Have I Been Pwned? database.[11][12][13]

Following extortion demands that escalated to US$15 million during negotiations, portions of the stolen databases were posted on underground forums in early November 2024.[13][14]
