Star Health Insurance data leak: 31M+ customers exposed on Telegram
A hacker has reportedly used Telegram chatbots to leak confidential customer data from Star Health, one of the largest health insurance providers in India. The leaked information includes medical reports and personal details of millions of policyholders. This security breach comes on the heels of allegations against Telegram's founder, Pavel Durov, for enabling criminal activities through his messaging app.
Insurance provider responds to data breach allegations
In response to the alleged unauthorized data access, Star Health has issued a statement. The company, valued at over $4 billion, has reported the incident to local authorities. Despite initial assessments suggesting no widespread compromise and assuring that sensitive customer data remains secure, Reuters was able to download policy and claims documents via these chatbots. These documents contained personal information such as names, phone numbers, addresses, tax details, copies of ID cards as well as medical test results and diagnoses.
Telegram's chatbot feature under scrutiny
The ability to create chatbots has significantly contributed to Telegram's growth as a leading messaging app with 900 million active monthly users. However, this feature is now under scrutiny due to its potential misuse for cybercrimes. The arrest of Durov in France last month has intensified this scrutiny, focusing on content moderation and features that could be exploited for illegal purposes. Both Durov and Telegram have denied any wrongdoing and are addressing these criticisms by introducing privacy-focused features.
Security researcher uncovers chatbots leaking Star Health data
UK-based security researcher Jason Parker discovered the chatbots leaking Star Health data. These bots, operational since at least August 6, display a welcome message stating they are "by xenZen." Parker interacted with a user named xenZen on an online hacker forum who claimed to have created these bots and possessed over 7.24TB data related to over 31 million Star Health customers. The data is freely available via the bot on a random basis but can also be purchased in bulk.
Telegram takes action against data-leaking chatbots
After being alerted about the data-leaking bots on September 16, Telegram took them down within 24 hours. The company's spokesperson, Remi Vaughn, stated that private information sharing is strictly prohibited on their platform and is removed whenever discovered. Despite this action, new chatbots offering Star Health data have since emerged. Following the data leak, Star Health has been actively collaborating with law enforcement to address this illegal activity.
