Customer Data Allegedly Shared Leading to Phishing Attack and Unsolicited HDFC Bank Credit Card

HDFC BankPC-2026-02901Banking & LoansAnonymous ·
Cyber security alert HDFC Bank has poor cyber security and they share the data of their clients carelessly. My phone number was shared and I was victim of a phishing attack and ended up getting a credit card. Complete details are shared with marketing department of HDFC Bank which gets access to your financial status, phone number and address. They need to be reported to Reserve Bank of India (RBI) before a bigger fraud takes place. Their motto business before security. HDFC entities have experienced multiple cybersecurity challenges, regulatory penalties, and high-profile data incidents. The group’s subsidiaries and vendor ecosystems have repeatedly faced significant threats, drawing intense regulatory scrutiny. Avinindra Kumar Singh sir request you to please look into the matter and tag cyber security experts for this phishing attack case. State Bank of India's data has been found on the dark web, if the security at HDFC is not tightened, same may be the case. SBI is finding it hard to explain how address and phone number of users are available on the dark web. Similarly HDFC Bank triggered a slew of calls from unvaried spam numbers to me after Customer Care Executive alloted to me by HDFC spoke to me. And they then sent me a credit card which I did not want. (PS: I worked with Cyber Security of Indian Army for two years. Here the entire data protection chain is compromised due to priority being on Profit. Data of those having credit card is not safe and there is little chance that it is now on the dark web) Cyber Security Authority
