How will AI increase the surface of cyber security attacks?

23 Oct 2024

AI is poised to increase the cybersecurity attack surface in several key ways, primarily by introducing new vulnerabilities in AI-driven systems, expanding AI-powered devices and providing cybercriminals with more sophisticated tools for exploiting weaknesses.

Here's how AI will enlarge the cybersecurity attack surface:

AI Systems as Targets

Vulnerabilities in AI Models:

AI systems can become a new target for cyberattacks. For example, adversarial attacks can exploit weaknesses in machine learning models, tricking AI into making incorrect predictions or decisions. Attackers could manipulate AI systems for facial recognition, autonomous vehicles or medical diagnostics, potentially leading to dangerous consequences.

Data Poisoning:

Machine learning models are highly reliant on training data. Attackers may poison datasets during training, introducing malicious or biased data that alters the AI's behaviour. This could lead to faulty decision-making in critical systems like financial fraud detection, healthcare or autonomous systems.

Model Inversion Attacks:

Hackers can attempt to reverse-engineer the AI models to extract sensitive information from them. In this attack, attackers could infer private data (such as individuals' personal information) by exploiting weaknesses in how AI models are trained and deployed.

Proliferation of AI-Powered Devices and Systems

IoT and Smart Devices:

Integrating AI into Internet of Things (IoT) devices will dramatically increase the attack surface. Smart homes, connected cars, healthcare devices and industrial systems rely on AI for decision-making and automation. Many IoT devices lack robust security measures and as they increasingly leverage AI, attackers will have more entry points to exploit vulnerabilities.

Edge AI Devices:

AI at the edge (e.g., in mobile phones, drones, or smart cameras) can create additional security risks. These devices often process data locally and may not have the same security protections as centralised systems, making them attractive targets for cyberattacks.

Autonomous Systems:

AI will play a critical role in autonomous systems such as self-driving cars, drones, and robots. Attacks on these systems could exploit AI vulnerabilities, causing them to behave unpredictably or dangerously.

AI-Augmented Attacks

AI-Driven Malware:

Attackers can use AI to develop adaptive malware that learns from its environment. For instance, AI-powered malware can evolve in real-time to evade detection by security systems, making it harder to detect and remove. This self-learning capability makes it much more resilient than traditional malware.

Automated Social Engineering:

AI can automate and amplify social engineering attacks, such as phishing or spear-phishing campaigns. It can analyse vast amounts of data to craft highly personalised and convincing phishing emails, voice calls or even deep fake videos that target specific individuals or organisations. This makes social engineering more scalable and effective.

AI-Generated Exploits:

Attackers will increasingly use AI to discover new vulnerabilities in software and systems more quickly. AI tools can scan codebases and networks at scale, identifying weaknesses faster than human attackers. Once a vulnerability is found, AI can help automate the creation of exploits, speeding up the attack process.

Attack Surface Expansion Through AI Supply Chains

AI Supply Chain Attacks:

The AI development process involves various external components like open-source frameworks, libraries, pre-trained models, and datasets. These supply chains can be compromised, leading to the insertion of backdoors or vulnerabilities during the AI development lifecycle. Attackers may compromise third-party vendors or software dependencies in AI model development, leading to widespread exploitation.

Third-Party Dependencies:

Many AI systems use cloud services or third-party platforms. If these external platforms are compromised, attackers could gain access to AI systems, increasing the overall attack surface.

Complexity of AI Systems

Increased Complexity Equals More Vulnerabilities:

As AI systems become more complex, the probability of vulnerabilities increases. AI applications often involve multiple layers of software, APIs and integrations with various services, each of which can introduce a potential security gap. This increased complexity can make it harder for security teams to audit and secure the entire system comprehensively.

Model Interpretability and Auditing Challenges:

Many AI models, intense learning systems, are seen as "black boxes" because they operate in ways that are not always easily interpretable. This lack of transparency makes it difficult for security teams to detect when models have been tampered with or compromised, increasing the risk of subtle but harmful attacks.

AI in Critical Infrastructure

Vulnerabilities in AI-Controlled Critical Systems:

AI is increasingly used to manage critical infrastructure such as energy grids, water supply systems and transportation networks. Attacks on these AI-controlled systems could have widespread consequences. For instance, a successful cyberattack could disrupt power grids, water distribution or traffic management, leading to physical harm or widespread disruption.

AI-Generated Misinformation:

AI can generate false information, deepfake content or fake news at scale, which can manipulate public opinion or cause reputational harm to businesses. AI-driven misinformation campaigns can destabilise organisations or governments by exploiting public trust in digital communications.

Summary

While AI offers numerous benefits in automating and enhancing cybersecurity efforts, it also presents new challenges by broadening the attack surface. As AI becomes more pervasive in business, critical infrastructure and daily life, the potential entry points for attackers will multiply. AI-powered attacks will be faster, more sophisticated and potentially more complex to defend against, requiring organisations to adopt equally advanced defensive measures to keep pace with, for example having a security operations centre SOC 24-7-365 will be a mandatory requirement to
