Indian cryptocurrency exchange BuyUCoin says it is investigating claims that sensitive data related to hundreds of thousands of its users has been leaked online. The 6GB of leaked data is said to have been found in a MongoDB database that was left unsecured, and included users bank account details, email addresses, mobile phone numbers, and Google sign-in tokens. The data was subsequently leaked by the ShinyHunters gang which has a history of publishing data breaches. The company is sending mixed messages regarding whether a breach has occurred or not.”]
