A CoWIN data breach on Telegram has shaken the internet. Reports suggest that leaked data is available on the popular social media platform Telegram, which can now be accessed by any user by entering mobile numbers. All personal information including PAN and Aadhaar card details can be accessed say reports.

The Government of India has denied all the reports and said that they were without any basis and mischievous in nature. “CoWIN portal of Health Ministry is completely safe with adequate safeguards for data privacy. Furthermore, security measures are in place on CoWIN portal, with web application firewall, anti-DDoS, SSL, TLS, regular vulnerability assessment, identity and access management.

What the CoWIN Development Team has to say about CoWIN Data Breach on Telegram

The CoWIN development team has verified that there are no publicly accessible APIs that allow data retrieval without an OTP. Furthermore, certain APIs have been provided to select third parties like ICMR for data sharing purposes. Among them, there is an API that permits data sharing by using only a mobile number or Aadhaar. However, this particular API is highly specific and exclusively accepts requests from a trusted API that has been authorized and whitelisted by the CoWIN application.
