Across the world, the profound effects of fraud on organisations have uncovered the far-reaching consequences it can have on data integrity, reputation and customer trust. Unmesh Kurup, Director, ML, Intuition Machines, delves into the world of online fraud, abuse and the paramount importance of CAPTCHA in today’s cybersecurity landscape. He unravels new tactics employed by cybercriminals to exploit vulnerabilities and deceive unsuspecting victims and protective measures to mitigate risks and safeguard sensitive information.
What are the most common causes of online fraud and abuse?
Data breaches often serve as the initial catalyst for most cases of online fraud and abuse. Once a system is compromised and data is extracted, it opens the gateway to various malicious activities such as phishing, malware attacks and additional vulnerabilities being exposed. The consequences of these breaches are straightforward, with identity theft being most commonly talked about.
Beyond this, there are other kinds of fraud such as credit card fraud, ticket scalping and merchandise scalping. There are also financial frauds, e-commerce or online gaming fraud but what sets apart the contemporary landscape of online fraud and abuse is its widespread prevalence, primarily due to extensive automation. Fraud has existed since the dawn of civilisation, but instances of fraud required a considerable amount of time and effort from individuals. But today, automation allows fraudsters to scale up their operations effortlessly.
What are the effects of fraud on an organisation?
In the short term, financial and reputational damage are most immediate. Long term secondary effects include operational disruption. Companies providing a service and making a product have a roadmap they are trying to execute and if they’re fighting fraud, they don’t have time and the bandwidth to execute on that roadmap which means they fall behind. That leads to a loss of competitive advantage and of course, decreased morale within the company.
What is a CAPTCHA and how does a CAPTCHA test prevent online fraud, data corruption and spam?
A CAPTCHA is a test of humanness. The reason for the test is because we want to prevent automation from overwhelming our systems. The goal is to determine if the entity interacting with the platform is a human or an automated bot. In the case of a bot, we would implement more restrictions. So, this is a test of humanness. This is only one part of our security ML platform for online fraud and abuse prevention, but it integrates with our other tools.
A CAPTCHA solution is an integral component of a comprehensive security framework. I like to think of CAPTCHA as the tip of an iceberg – with an iceberg, only a fraction is visible above the water, and you don’t see it often. That’s how a comprehensive security platform is – you don’t see it most of the time but every once in a while, you see it. That’s the CAPTCHA. That’s the part you interact with as a user.
What are the risks of not implementing a CAPTCHA and why is it essential in cybersecurity?
The main purpose of implementing CAPTCHAs is to regulate and stop automated attempts by individuals trying to breach your system. It prevents brute force attacks and various forms of phishing. Preserving the integrity of data is fairly obvious to everyone but even if you have no data to safeguard, it’s still important to protect your resources.
How can organisations implement gateway solutions to detect anomalies and spot security warning signs that can raise appropriate alerts?
It all begins with establishing appropriate internal policies that govern the safeguarding of data, data loss prevention policies, security life cycle policies and overall security measures.
After these internal steps, the focus drifts to defensive systems like firewalls, intrusion detection and prevention systems, as well as security information and event management systems. These are collective components of a security solution.
Many companies employ a more dynamic technique to enhance their security posture like human security analysts who examine data to ensure that no anomalies or potential threats go unnoticed and teams that continually battle each other to identify vulnerabilities within the system. Some organisations may go further to employ penetration testing to assess the strength of their security defences.
What are the key considerations when determining the optimal Machine Learning approach for implementing CAPTCHA?
It all starts with performance. One of the challenges associated with AI and Machine Learning is staying ahead of the rapid evolution cycle of fraud and abuse tactics. That is why performance is important. Do these CAPTCHAs effectively capture and mitigate bots? Do they provide an optimal user experience for customers? These performance considerations lay the foundation for all endeavours.
Privacy has also become a significant concern today. Beyond compliance with regulations such as GDPR or CCPA, people are increasingly aware of their personal data being at risk. As a result, it is imperative for Machine Learning and AI to be aware of privacy issues and avoid any inadvertent data leaks.
Accessibility also plays a crucial role in this approach. We always say we are in the business of detecting humans, not bots. So, our approach is to make something that is user-friendly and accessible to people. CAPTCHAs traditionally rely on image recognition, but we go beyond that. We provide alternative ways for people to access the system without having to interact with the CAPTCHA if they have an accessibility issue. So, we cater for individuals with diverse accessibility needs and ensure that the system accommodates everyone, regardless of any accessibility limitations.
What sets hCaptcha apart as an exceptionally potent defence system against sophisticated and automated attacks, specifically in terms of its ML-based solutions and their ability to fortify online properties?
At hCaptcha, our approach revolves around the comprehensive leverage of AI and Machine Learning across all aspects of our system, especially to scale our capabilities to match the magnitude of sophisticated attacks by perpetrators. That way, we meticulously scrutinise every data we encounter and our system, which is designed to handle millions of requests per second, ensures exceptional speed, accuracy and efficiency.
With our operations, most of the data processing occurs within the client’s local jurisdiction enabling us to adhere to your local laws and regulations such as GDPR and CCPA, and hCaptcha can be deployed within minutes to get up and running.
We prioritise a low-friction experience, empowering you to swiftly harness the power of our solutions. And for privacy, data protection and other pertinent regulations, rest assured, we do not collect any personally identifiable information, safeguarding your sensitive data and maintaining your compliance obligations.
We realise the importance of having a global view of emerging threats in other parts of the world which means we can protect our clients before they experience new attacks.
While we maintain this global perspective on emerging threats across the Internet, we understand that every company faces unique challenges. So, we provide personalised Machine Learning models for your data that takes into account what is happening on a global scale, but also the specific threats you face.
We also provide advanced threat protection services. We detect coordinated attacks targeting your system and an array of supplementary tools, including in-house software to provide an extra layer of protection and vigilance. For effective monitoring and analysis, our team offers advanced dashboards and KPIs which can be seamlessly integrated into your existing internal tools. We support a wide range of organisations from those starting off with security to organisations with large security analyst teams. All of these are what make us unique.
Traditional CAPTCHAs have been flagged for violating privacy laws such as GDPR and collecting user information without proper consent. What makes hCaptcha unique in its approach to bot and fraud management?
Our approach is very unique because all our data is processed locally within the relevant jurisdiction where the user interacts. We do not retain any personally identifiable information or track users across websites. Our services are geared toward providing even more advanced privacy options to customers which includes zero personally identifiable (PII) information, even blinding IP addresses before we see them.
For example, a customer may request they do not want any information from users to reach the page captcha and we make that possible. Customers can blind all users’ private information before sending it to us and we’re still able to perform analysis to detect threats.
How does the AI revolution affect online fraud, data corruption and spam?
Data corruption, spam, fraud and abuse have existed since the dawn of civilisation. Automation is supercharging the fraud and abuse that’s happening now. It’s always been a cat-and-mouse game between people trying to commit fraud and people trying to stop fraud.
AI and Machine Learning are only bad if a company is stagnant and dependent on existing solutions because then their systems will be overwhelmed by always-evolving techniques. For hCaptcha, we constantly evaluate the latest techniques and technologies, allowing us to stay a step ahead of threat actors. That way we can scale up our threat detection abilities beyond the capabilities we had even a few months ago, based on the latest ML technologies, computing and hardware developments.
So, my key advice would be for organisations to embrace the revolution in AI and Machine Learning to stay ahead of the game.Click below to share this article
