When contacted, Unacademy co-founder and Chief Technology Officer Hemesh Singh said the company has been closely monitoring the situation and claimed that no sensitive information such as financial data or location has been breached.

"As per our internal investigations, e-mail data of around 11 million users has been compromised as against 22 million stated in reports. This is on account of only around 11 million e-mail data of users available on the Unacademy platform," Singh said.

He said the company is following stringent encryption methods and making it highly implausible for anyone to decrypt passwords.

"We also follow an OTP-based login system that provides an additional layer of security to our users. We are doing a complete background check and will be addressing any potential security loophole to further bolster our efforts of ensuring a far more robust security mechanism. We are in communication with our users to keep them updated on the progress," Singh said.

Facebook, General Atlantic, Sequoia India, Flipkart CEO Kalyan Krishnamurthy, and Nexus Venture Partners have invested in the company. According to Cyble, this breach can have an impact on security of other companies as well.

"Cybercriminals are always on the lookout for such breaches and utilise them for credential stuffing attacks. We have seen accounts/records with domain names from Infosys, TCS, Cognizant, Reliance Industries, HDFC, Accenture, ICICI, SBI, Canara Bank, Bank of Baroda, Punjab National Bank and several other large organisations," Cyble said.
