Cybersecurity: AI-Based Threats
While AI enhances the capabilities of cybersecurity systems, it has created new avenues for cybercriminals. AI-driven attacks, such as AI-generated phishing emails, are becoming increasingly sophisticated. These emails can mimic human communication with remarkable accuracy, making it easier to deceive users into sharing sensitive information or credentials. As phishing techniques evolve, organisations must stay ahead by leveraging AI to detect and counteract such attacks.
Moreover, the use of AI in cyberattacks is not limited to phishing—AI also powers the development of malware and ransomware that adapt in real-time, learning to bypass traditional defence mechanisms. This arms race between attackers and defenders defines the modern cybersecurity landscape. Organisations must invest in AI-driven threat detection systems that can adapt as quickly as the threats they face.
Shift from Passwords to Passkeys
In response to these rising threats, the cybersecurity industry is witnessing a shift from passwords to passkeys, offering more secure and user-friendly alternatives. Traditional passwords, long considered the weak link in digital security, are being replaced by passkeys enabled by technologies such as FIDO (Fast Identity Online). This shift allows users to authenticate themselves without transmitting a password over the internet, making it significantly harder for attackers to intercept or steal credentials. Passkeys are stored securely on the user’s device, offering both simplicity and enhanced security.
Passkeys utilise public-key cryptography, where a private key is stored on the user’s device and a public key is registered with the service provider. During authentication, the device signs a challenge with the private key, and the service provider verifies the signature with the public key. This process eliminates the need for passwords and reduces the risk of credential-based attacks.
Deepfake Technology
Deepfakes use AI to manipulate voice, images, and video, creating highly convincing but fake representations of real people. This technology has already infiltrated social media and communication platforms, with attackers using deepfakes to impersonate individuals in phishing schemes, blackmail, or financial scams.
Deepfake detection technology is currently being developed, but it is becoming clear that detection alone will not be sufficient. As deepfakes continue to evolve and improve, the focus must shift towards building robust security measures that do not rely solely on identifying deepfakes. This could involve multifactor authentication methods or verification processes that ensure a person’s identity through means other than audio or visual confirmation.

For instance, organisations can implement biometric authentication methods that combine facial recognition with voice analysis and behavioural patterns. Additionally, blockchain technology can be used to create tamper-proof records of digital communications, making it harder for attackers to manipulate data.
AI Hallucinations
Another major concern in the AI space is the issue of AI hallucinations, where generative AI models produce incorrect or misleading information. As businesses and individuals become more reliant on AI systems to provide information and make decisions, the risk of AI-induced errors or security vulnerabilities grows. Hallucinations could lead to critical mistakes, particularly in environments where AI is trusted to perform sensitive tasks.
To mitigate this, technologies like retrieval-augmented generation (RAG) are being explored to improve the accuracy of AI outputs. These systems combine AI’s generative capabilities with real-time data retrieval, reinforcing the validity of the information provided and reducing the likelihood of errors. RAG works by integrating a retrieval model that fetches relevant information from a database, which is then used by the generative model to produce accurate outputs.
Future Projections
Looking ahead, the relationship between AI and cybersecurity will continue to evolve. AI will play an increasingly important role in fortifying cybersecurity defences, but it will also drive the evolution of new threats. Organisations must balance adopting AI for defence with ensuring that the AI systems themselves are secure and trustworthy.
In the future, we can expect to see more advanced AI-driven threat detection systems that can adapt to new and emerging threats in real-time. Additionally, the use of AI in cybersecurity will likely become more integrated with other technologies, such as blockchain and quantum computing, to create more robust and secure systems.
