 How To Prevent Bank Frauds With Programming Languages.




Bank frauds nowadays is getting serious and tricky especially in cases where technology is improving gradually. Scammers uses this opportunity to defraud bank accounts and hack the bank's customer personal details list so that they will get your information and try to vandalize your account.


How does it work.

Bank frauds works with a wide range of illegal activities with the unlawful way of getting money, source of income and confidential information from businesses, financial institutions and individuals. The schemes can be very advanced taking vulnerabilities in the system, technological development and human behavior. There are common ways bank frauds work:

1. Credit Card Fraud: Scammers get information of the victim credit card by various means like data breaches, hacking or from payment devices hacked by scammers in other to copy information from the ATM card. They will use the information to make transactions, purchase goods or withdraw cash with you knowing. 

2. ATM Skimming: Scammers attach devices in the ATM and hack the POS terminal to collect information and PIN from users. They use the data to clone onto fake cards to use it for online transactions. 

3. Identity Theft: They steal the victim personal information like password and Social Security numbers to impersonate victims and open fraudulent accounts. They use the stolen identity and apply for financial services. 

4. Wire Fraud: Criminals convince businesses and individuals to transfer funds into accounts controlled by the Criminals. They disguise as legitimate vendors, suppliers and executives and provide invoices and payment requests in order to deceive victims to paying money into their accounts. 

5. Ponzi Schemes: Ponzi is when fraudsters promise high returns to investors but use the funds of newer investors to pay the older investors. They make everyone to invest until the scheme falls and leaves everyone with losses.

6. Cyberattacks: Fraudsters uses vulnerabilities in the computer systems and networks of the banks. They use many hacking techniques to steal data from the banks and hijack he services. 

7. Phishing: Scammers impersonate many institutions on emails, phone calls messages and text messages. They deceive individuals by convincing them to reveal their confidential information credentials and financial details.

8. Taking Over The Account: Criminals gain access to a individual's bank account by stealing login information and passing through weak security practices. Once they get it, they make unauthorized transfers withdraws and payments.


How To Prevent It With Language Codes.


Preventing bank frauds with programming languages requires implementation of security measures leveraging available libraries and adoption of best practices. However, even though the codes are basic and not sophisticated, it may be used as a example to create a better and more powerful code for bigger scam tactics. While in the basic, you can use these codes for normal domestic prevention

Here are the codes you can use to secure your account in Java, Python, Swift, C++ and Ruby:

In Java, there are two codes you need to use in order to secure your account.


Java 

Secure Communication and Authentication. 


// Using Spring Security for secure communication and authentication

@Configuration

@EnableWebSecurity

public class SecurityConfig extends WebSecurityConfigurerAdapter {

    @Override

    protected void configure(HttpSecurity http) throws Exception {

        http

            .requiresChannel()

                .anyRequest().requiresSecure()

            .and()

            .formLogin()

                .loginPage("/login")

                .permitAll()

            .and()

            .authorizeRequests()

                .antMatchers("/public/**").permitAll()

                .antMatchers("/private/**").authenticated();

    }

}


Data Encryption:


// Using Java Cryptography Architecture (JCA) for data encryption

import javax.crypto.Cipher;

import javax.crypto.KeyGenerator;

import java.security.Key;

import java.util.Base64;


public class EncryptionExample {

    public static void main(String[] args) throws Exception {

        String originalData = "Sensitive data to encrypt";


        // Generate a symmetric key

        KeyGenerator keyGen = KeyGenerator.getInstance("AES");

        keyGen.init(128);

        Key key = keyGen.generateKey();


        // Encrypt the data

        Cipher cipher = Cipher.getInstance("AES");

        cipher.init(Cipher.ENCRYPT_MODE, key);

        byte[] encryptedData = cipher.doFinal(originalData.getBytes());


        System.out.println("Encrypted Data: " + Base64.getEncoder().encodeToString(encryptedData));

    }

}


Python 


Secure Communication and Authentication:


# Using Flask for secure communication and authentication

from flask import Flask, request

from flask_httpauth import HTTPBasicAuth


app = Flask(__name__)

auth = HTTPBasicAuth()


@auth.verify_password

def verify_password(username, password):

    # Implement your authentication logic here

    return username == "user" and password == "password"


@app.route('/private')

@auth.login_required

def private_route():

    return "Private data"


if __name__ == '__main__':

    app.run(debug=True)


Data Encryption:


# Using cryptography library for data encryption

from cryptography.fernet import Fernet


key = Fernet.generate_key()

cipher_suite = Fernet(key)


original_data = b"Sensitive data to encrypt"

encrypted_data = cipher_suite.encrypt(original_data)


print("Encrypted Data:", encrypted_data)


Swift.


Secure Communication and Authentication 


import Foundation


// Using URLSession for secure communication and authentication

let url = URL(string: "https://example.com/api/resource")!


var request = URLRequest(url: url)

request.httpMethod = "GET"


let username = "user"

let password = "password"

let loginString = "\(username):\(password)"

let loginData = loginString.data(using: .utf8)

let base64LoginString = loginData?.base64EncodedString()


request.setValue("Basic \(base64LoginString)", forHTTPHeaderField: "Authorization")


let task = URLSession.shared.dataTask(with: request) { data, response, error in

    if let data = data {

        let responseString = String(data: data, encoding: .utf8)

        print("Response: \(responseString ?? "")")

    }

}


task.resume()


Data Encryption: 


import Foundation

import CryptoKit


let originalData = "Sensitive data to encrypt".data(using: .utf8)!


// Generate a symmetric key

let key = SymmetricKey(size: .bits256)


// Encrypt the data

let encryptedData = try! AES.GCM.seal(originalData, using: key).ciphertext


print("Encrypted Data:", encryptedData)


C++


Secure Communication and Authentication:


#include <iostream>

#include <curl/curl.h>


int main() {

    CURL *curl;

    CURLcode res;


    curl_global_init(CURL_GLOBAL_DEFAULT);

    curl = curl_easy_init();

    if (curl) {

        const char *url = "https://example.com/api/resource";

        curl_easy_setopt(curl, CURLOPT_URL, url);


        const char *userpwd = "user:password";

        curl_easy_setopt(curl, CURLOPT_USERPWD, userpwd);


        res = curl_easy_perform(curl);

        if (res != CURLE_OK) {

            fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));

        }


        curl_easy_cleanup(curl);

    }

    curl_global_cleanup();


    return 0;

}


Data Encryption:


#include <iostream>

#include <string>

#include <openssl/aes.h>


std::string encryptAES(const std::string &input, const std::string &key) {

    AES_KEY aesKey;

    if (AES_set_encrypt_key(reinterpret_cast<const unsigned char *>(key.c_str()), 128, &aesKey) != 0) {

        std::cerr << "AES key initialization error" << std::endl;

        return "";

    }


    unsigned char encrypted[128];

    AES_encrypt(reinterpret_cast<const unsigned char *>(input.c_str()), encrypted, &aesKey);


    return std::string(reinterpret_cast<char *>(encrypted));

}


int main() {

    std::string originalData = "Sensitive data to encrypt";

    std::string key = "0123456789012345"; // 16 bytes


    std::string encryptedData = encryptAES(originalData, key);

    std::cout << "Encrypted Data: " << encryptedData << std::endl;


    return 0;

}


Ruby 


Secure Communication and Authentication:

require 'net/http'

require 'uri'

require 'base64'


url = URI.parse('https://example.com/api/resource')

http = Net::HTTP.new(url.host, url.port)

http.use_ssl = true


request = Net::HTTP::Get.new(url.path)

request.basic_auth('user', 'password')


response = http.request(request)

puts "Response: #{response.body}"


Data Encryption:


require 'openssl'


original_data = 'Sensitive data to encrypt'

key = '0123456789012345' # 16 bytes


cipher = OpenSSL::Cipher.new('AES-128-ECB')

cipher.encrypt

cipher.key = key


encrypted_data = cipher.update(original_data) + cipher.final

puts "Encrypted Data: #{encrypted_data}"
