The Evolution of AI Threat Actors: A Cybersecurity Challenge
How AI technologies are being used by threat actors and the implications for cybersecurity.
Artificial intelligence (AI) is a powerful technology that can enhance the capabilities of humans and machines. However, it can also be used for malicious purposes by threat actors who seek to exploit vulnerabilities, steal data, disrupt operations, or cause harm. AI threat actors are those who use AI technologies to launch cyberattacks or to evade detection and response. They can leverage AI to automate, optimize, or augment their attack vectors, such as phishing, malware, ransomware, denial-of-service, or social engineering. AI threat actors can also use AI to generate realistic and convincing fake content, such as deepfakes, synthetic voices, or fake news, to manipulate, deceive, or influence their targets. AI threat actors pose a serious challenge for cybersecurity, as they can increase the scale, speed, sophistication, and stealth of their attacks, and make them more difficult to detect, prevent, or mitigate.
The Evolution of AI Threat Actors
AI threat actors are not a new phenomenon, but they have evolved over time as AI technologies have become more accessible, affordable, and advanced. The evolution of AI threat actors can be divided into three phases:
Phase 1: Early Adopters. In this phase, AI threat actors were mostly state-sponsored or well-funded groups who had access to high-end AI technologies and expertise. They used AI to enhance their existing cyber capabilities, such as reconnaissance, encryption, or obfuscation. For example, in 2010, the Stuxnet worm, which targeted Iran's nuclear facilities, used AI to evade antivirus software and to adapt to different environments. In 2016, the Project Sauron malware, which targeted government and military organizations, used AI to generate unique encryption keys and to blend in with normal network traffic.
Phase 2: Mainstream Users. In this phase, AI threat actors became more diverse and widespread, as AI technologies became more available, affordable, and user-friendly. They used AI to automate and optimize their attack vectors, such as phishing, malware, ransomware, or denial-of-service. For example, in 2017, the WannaCry ransomware, which infected millions of computers worldwide, used AI to scan for vulnerable systems and to spread rapidly. In 2018, the Emotet malware, which targeted banking and financial institutions, used AI to generate personalized and convincing phishing emails.
Phase 3: Innovators. In this phase, AI threat actors are expected to become more creative and disruptive, as AI technologies become more advanced, powerful, and versatile. They will use AI to augment and generate new attack vectors, such as deepfakes, synthetic voices, or fake news. They will also use AI to evade and counter the AI-based defenses of their targets, such as anomaly detection, behavior analysis, or biometric authentication. For example, in 2019, a CEO of a UK-based energy firm was tricked into transferring $243,000 to a fraudster who used AI to mimic the voice of his boss. In 2020, a deepfake video of a Belgian politician was circulated online, in which he appeared to endorse a far-right party.
The Implications for Cybersecurity
The evolution of AI threat actors has significant implications for cybersecurity, as they pose new and complex challenges for the defenders. Some of the implications are:
Increased Attack Surface. AI threat actors can exploit the vulnerabilities of the AI systems themselves, such as data poisoning, model stealing, or adversarial attacks. They can also target the human users of the AI systems, such as social engineering, phishing, or spoofing. Moreover, they can attack the infrastructure and devices that support the AI systems, such as cloud servers, IoT devices, or networks.
Reduced Detection and Response Time. AI threat actors can launch faster, stealthier, and more adaptive attacks, which can evade the traditional security measures, such as signatures, rules, or firewalls. They can also use AI to generate realistic and convincing fake content, which can deceive the human analysts, such as security operators, investigators, or decision-makers.
Increased Impact and Damage. AI threat actors can cause more harm and damage to their targets, as they can scale up, optimize, and diversify their attacks, such as infecting more systems, demanding higher ransoms, or disrupting more operations. They can also cause more psychological and social harm, as they can manipulate, deceive, or influence their targets, such as eroding trust, spreading misinformation, or inciting violence.
TLDR
AI threat actors are a growing and evolving cybersecurity challenge, as they use AI technologies to launch more sophisticated, effective, and harmful cyberattacks. They can exploit the vulnerabilities, target the users, and attack the infrastructure of the AI systems. They can also evade the traditional security measures, deceive the human analysts, and counter the AI-based defenses. They can also cause more harm and damage to their targets, both in terms of technical and psychological aspects. Therefore, cybersecurity professionals need to adopt a proactive, adaptive, and collaborative approach to defend against the AI threat actors, by leveraging AI technologies, enhancing human capabilities, and strengthening security culture.
