My Experience with Google Cloud Platform AI Services
In today's digital era, safeguarding sensitive information against cyber threats is paramount. As a cybersecurity enthusiast, I embarked on a transformative journey leveraging Google Cloud Platform's (GCP) advanced AI solutions to combat one of the most pervasive threats: Account Takeover (ATO) fraud.
The impact of account takeover fraud is significant! As per the Javelin 2023 Identity Fraud Study, 15.4 million U.S. adults have been victims of ATO.
Project Overview
The project centered on addressing the rampant ATO fraud targeting financial institutions, e-commerce platforms, and digital services. Criminals use cybercrime methods and automated bots to access user accounts without permission, resulting in financial losses and fraudulent actions.
Creating an AI-Powered Solution
To combat ATO fraud effectively, I developed a robust Software Development Kit (SDK) embedded with advanced AI models. These models, designed with well-defined features, enabled detection of fraudulent activities within login, onboarding, and payment transaction flows.
Addressing the Problem Landscape
The project delves into various methods through which credentials are stolen. Each method posed unique challenges, requiring tailored AI solutions. The overarching philosophy was to capture the anomalies observed in a user’s journey on an e-commerce/banking/financial institution’s site and provide a cumulative risk score. This risk score can be mapped to a set of actions leading to reduction in Fraud losses.
Some of the methods that I explored along with possible solutions:
1. Social Engineering:
Attackers manipulate or coerce account holders to disclose their login credentials through social interactions, requesting individuals to share their screen and retrieve security credentials, or getting control of the victim’s PC utilizing software like AnyDesk.
Possible Solution: Implement measures to detect screen recording or system dual control and prevent users from accessing pages containing sensitive information. Also, consider disabling the payment gateway if suspicious activity is detected.
2. Credential Stuffing:
Credential stuffing involves attackers using automated tools to test various combinations of compromised usernames and passwords across multiple websites, exploiting users who reuse credentials. The attack fetches usernames and passwords from a phishing attack, website breach, password dump, etc. The attacker utilizes automated tools to test the stolen credentials against several sites. If the attacker logs in successfully, he easily gets a set of valid credentials.
Possible Solution: Apply measures to limit login attempts based on device fingerprinting. Additionally, keep a check on suspicious behaviors such as distinct typing speeds, time zones, or IP addresses, especially when trying multiple credentials in a short period of time. These precautions can help detect and prevent credential stuffing attacks.
3. Brute Force Attacks:
Brute force attacks entail hackers trying several combinations of passwords and usernames until they find one that grants access to an account.
Possible Solution: Restrict API calls based on the device fingerprint to prevent excessive attempts. Implement a methodology to check that the same user (identified by characteristics such as typing speed, device fingerprint, timezone/IP address) is attempting different passwords.
4. Keylogging:
Keylogging is a form of client-side malware where attackers steal credentials by injecting malicious scripts into online forms, capturing sensitive information such as login credentials and credit card details.
Possible Solution:
Implement Web Application Firewalls (WAFs) to filter and track HTTP traffic, detecting and blocking malicious activities, including script injections.
Deploy a Content Security Policy (CSP) to alleviate the risk of cross-site scripting (XSS) attacks, commonly utilized for script injections.
Ensure HTTPS encryption for your website to encrypt data transmission between the client and server, improving security and securing against data interception.
5. Skimming And E-Skimming:
Skimming includes copying the cardholder’s payment details, with criminals utilizing different strategies like photocopying receipts, e-skimming, or installing skimmers within ATM terminals to capture card numbers and PINs.
Today's highly advanced form of skimming is e-skimming, which involves infecting e-commerce sites with malicious code to take the customer's debit or credit card information. Because it does not involve physical tampering with a device, it’s tougher to detect than other types of skimming. The customer enters their card information, assuming it to be a secure transaction, but the malicious code included in the website saves their data and transfers it to the hackers in real time.
Possible Solution:
Implement Web Application Firewalls (WAF) to filter and track HTTP traffic between a web application and the internet. This can help find and block malicious activity, which includes attempts to inject skimming scripts.
Implement a Content Security Policy (CSP) to reduce the risk of cross-site scripting (XSS) attacks, which are widely used to inject skimming scripts into web pages.
6. Man in the Middle (MitM) Attacks:
Man in the Middle (MitM) attacks include intercepting messages or data transfers by acting as proxies between legitimate parties. This enables the attacker to "eavesdrop" on the exchange of information and data between the two parties, harvesting login credentials or other personal information.
Possible Solution:
Extra security measures that were outside the scope of this project.
