Lets Hack Banks make them Cry


Finding all the vulnerabilities and valuable exploits in a Local bank website

You guys must have tried to hack many applications. Have you ever thought that we can break into the local bank and collect some information that will be very useful for you. It takes a lot of time. Sometimes it takes three days, months and sometimes years of effort. will understand the follies.

I don’t want to teach cyber security that way like the old guys, well you’ll do it all on top of a learning lab, but how do you know until you set up a Rails target on top of a Rails machine? I will tell you what you want to do. I don’t want to take you to any fiction, I want to show you the reality of how complex things become.

Be aware :

that publicizing any company’s personal information is an unethical practice and an illegal crime. Your state can also file a serious case related to this against you, so please do not make this thing without permission, otherwise the loss will be yours.

Hello my name is Imran Niaz and I am a cyber security penetration tester my experience is in breaking security of web application architecture. I try to get my hands on the API the most and the directory traversal because many times I get good information from there.

Which makes my job easier. We’ll see how we can find things inside the banks. We’ll try to bypass firewalls. It will be long, videos will also be uploaded in the video part, which will help you understand many things, there will be a theory, many commands and many tools will be used.

First of all we have to collect the links of all these websites which are of banks, we have made a sim related tutorial. We will divide all the things into different parts and see what we can get from there. Let’s see about this thing in the video below and understand a diagram.

How the banking system works,10 major components that ultimately control the banking web application:

Out of all this information, the most important information will be the one that we have bolded from where we can pick things up.

  1. Core Banking System
  2. Online Banking Application
  3. Payment Gateway
  4. Security and Compliance Systems
  5. Customer Relationship Management (CRM) System
  6. Risk Management and Analytics
  7. Backend Infrastructure
  8. Mobile Banking Applications
  9. Data Warehousing and Business Intelligence
  10. Customer Support and Communication Channels
  11. Regulatory Reporting and Audit Trail
  12. VOIP in Banking

Core Banking System:

As this is the first lecture on this topic, we would like to understand first of all what is in “Core Banking Networks ”and what is the difference between Core Banking Network and “Core Banking System”. And how are they working?

Which are the places in the bank where there is a lot of sensitive information and the attacks that happen will also be investigated. At that time, what was our mind thinking about what could happen.

Components in Banking Core System Web Application:

  1. User Authentication and Authorization
    2. Course Management
    3. User Profiles
    4. Content Management
    5. Discussion Forums
    6. Assessment and Grading
    7. Payment Integration
    8. Reporting and Analytics

Types of Attackers and Our Targets:

  • Malicious Users: Unauthorized access, content theft, and disruption.
  • Phishing Attackers: User credentials and personal information.
  • Data Thieves: Sensitive user data (personal and financial).
  • Instructors or Admin Impersonation: Unauthorized access and manipulation.
  • Content Scrapers: Theft of course content.
  • SQL Injection and XSS Attackers: Exploiting code vulnerabilities.

First set a target.

If you want to do condition testing in any place, then you should know what your target is and what you want to extract from your target. First we locked down our target and saw what was out there and then we started investigating them. The first thing we did was to find the subdomains and see how many they had. There are subdomains. To find subdomains, we used a tool called DNS Mapper.

dnsmap Builden tool in klai.i also have my own tool andSome Scipt your can use it for Finding Hidden Domain is. but if You wanna find with

https://github.com/imran-niaz/ You can see things here i Have

git clone https://github.com/imran-niaz/Subdomain/ you can use Sudo Command Extra Help is here

Find all Hidden Subdomains of domains with python
Sub domain is Part if your domain or any other origination what if you are able to find someone subdomains. there are a…imran-niaz.medium.com

when i get my favrat Subdomain that i was domaind to targe i open another tools so I can see where is trafig going.

“Wireshark + Nmap + DNSMAP”

When I found the subdomain, I scanned both IPs connected to the subdomain and used Nmap to scan the IP. And ran a simple command, which I found out through the ping request method that the AWS server is running there.

And when I went to the slog page of the subdomain, there I got an error, there was a blank space with a double slash, and I found out that they were using SP’s server. Did not reach the stages

putting Small Space so we understand what Framework they are using

Frequently asked questions

What is this guide about banking?

A complete guide to finding all the vulnerabilities and valuable exploits in a bank website explains practical, ethical notes on banking. Use it as a structured walkthrough — then practice only in authorized labs.

Who is this banking article for?

Readers who want clear, street-level guidance on banking without hype. Beginners and intermediate practitioners both benefit.

How do I practice banking safely?

Stay in scope: systems you own or have written permission to test. Keep notes, verify findings, and never attack live targets without authorization.
