The information of hundreds of thousands of Indians who received the COVID vaccine was Leaked in a significant data breach and posted on a Telegram channel. Numerous reports claim that sensitive information, including a person’s phone number, gender, ID card details, and date of birth, leaked over Telegram. It could be obtained by typing a person’s name into a Telegram bot.

What really happened?

The records pertaining to the mobile number registered in the CoWin portal are accessible on the Malayalam news website channel. It is also feasible to determine which vaccination was given and where it was given.

According to The Report, the list of individuals whose data was exposed includes BJP Tamil Nadu president K Annamalai, Congress MP Karti Chidambaram, and former BJP union minister for health Harsh Vardhan. Telangana’s minister of information and communication technology, Kalvakuntla Taraka Rama Rao, is also on the list.

MEITY stated in response to the data leak, “It is old data, we are still confirming it. We have requested a report on the matter.

After the media Report, the bot was disabled, but experts said the incident raised severe issues because the information might be used for identity theft, phishing emails, con games, and extortion calls. The Indian Computer Emergency Response Team (CERT-In), the government’s nodal body, has opened an investigation into the situation

The central government declared the data breach reports regarding the repository of beneficiaries against Covid to be “mischievous in nature” on Monday and claimed the ‘bot’ that purportedly accessed the confidential data was not directly accessing the CoWIN database.

According to the first complaint by CERT-In, the government’s cybersecurity division, the government claimed the bot might be displaying information from “previously stolen data.” Reports.

The health ministry refuted the claim, asserting that no bots could access the information without first verifying with a one-time password.

“It is made clear that all of these rumours are false and malicious. The health ministry’s CoWIN interface is entirely secure and has sufficient data privacy protections. The security of the data on the CoWIN portal is being ensured in every way possible, according to a statement from the health ministry.

Meity said the CoWin program or database was not directly compromised, and the shared information appeared to be taken from a previous intrusion. But the hack again highlights the growing danger of cyber assaults, particularly on official websites.
