Stolen customer data including medical reports from India's biggest health insurer, Star Health, is publicly accessible via chatbots on Telegram, just weeks after Telegram's founder was accused of allowing the messenger app to facilitate crime.

However, the arrest of Russian-born founder Pavel Durov in France last month has increased scrutiny of Telegram's content moderation and features open to abuse for criminal ends. Durov and Telegram denied wrongdoing and are addressing the criticism.

Parker said he posed as a potential buyer on a online hacker forum where a user under the alias xenZen said they made the chatbots and possessed 7.24 terabytes of data related to over 31 million Star Health
