As per latest reports, the Juspay data breach is a result of a compromised server of the Bengaluru-headquartered mobile payment solutions company.

It is being said that the credit card data leak India of Juspay users was concealed in places to expose only partial copies of card numbers, however, the Juspay data breach has now left millions of users vulnerable to phishing scams. Rajshekhar Rajaharia, cyber security researcher, who first spotted the breach, said that Juspay data breach could become a lot more serious if hackers figure out the encryption algorithm.Since the credit card data leak includes mobile numbers, they could call unsuspecting cardholders and trick them into giving out the full card numbers, PIN, CVV as well as OTP. He also explained that since these users are paying customers, the leak holds a lot of importance for scammers and hackers.
Juspay has acknowledged the credit card data leak, but has maintained that the data breach didn’t contain any sensitive information. Juspay founder Vimal Kumar said. “On 18 August 2020, an unauthorised attempt on our servers was detected and terminated when in progress. No card numbers, financial credentials or transaction data were compromised. Some data records containing non-anonymised, plain-text email and phone numbers were compromised, which form a fraction of the 10 crore data records.” He further added, “The masked card data (which is not sensitive) has 2 Cr user records. Our card vault, in a different PCI-compliant system with encrypted card data, was never accessed.”
