Emerging threats in 2024: How AI, IoT, and Deepfakes are shaping the Cybersecurity landscape

Cybersecurity is a constantly evolving battlefield, and as we step into 2024, the threat landscape is rapidly transforming. The growth of artificial intelligence (AI), the proliferation of Internet of Things (IoT) devices, and the increasing sophistication of deepfake technologies are reshaping how we think about cyber threats and how we defend against them. In this article, we explore how these emerging threats are challenging cybersecurity in 2024 and what organizations can do to stay ahead of these evolving risks.

The rise of AI in cyber attacks

Artificial intelligence is a double-edged sword in cybersecurity. On one side, it has tremendous potential for improving threat detection and response. On the other side, it is being weaponized by cybercriminals to execute more sophisticated attacks.

In 2024, AI is not just used by defenders; attackers are leveraging it for automated phishing campaigns, exploiting vulnerabilities faster, and even creating polymorphic malware that changes to evade detection. The AI-driven attacks of today are far more efficient, with sophisticated social engineering techniques that use AI to generate personalized phishing emails that are nearly impossible to distinguish from genuine communication.

One security team experimented involving 200 of their colleagues, found that an organization can be hit by an AI-generated spear-phishing campaign,and in which every email was uniquely tailored for each target, drawing on publicly available information, the success rate of this attack was worryingly high because even seasoned professionals fell for the convincing narratives.

How to defend against AI-driven attacks:

• User education: Train employees on recognizing phishing emails, even those that seem personalized. Employees are often the last line of defense.

• AI-powered defense: Use AI to fight AI. Implement advanced threat detection systems that leverage machine learning to identify anomalies and potential attacks in real time.

• Regular updates and patching: Attackers often leverage AI to exploit known vulnerabilities at scale. Keeping systems up to date is a fundamental, yet often neglected, part of defense.

IoT: A growing attack surface

The Internet of Things is connecting billions of devices worldwide, from smart appliances in homes to critical infrastructure in cities. While IoT brings convenience and efficiency, it also expands the attack surface, creating more opportunities for malicious actors.

In 2024, IoT devices remain a top target for cybercriminals due to their often-weak security posture. Many IoT devices are shipped with default credentials, lack firmware updates, or have inadequate encryption, making them easy entry points for attackers. Once compromised, these devices can be used as a launchpad for larger attacks, including Distributed Denial of Service (DDoS) attacks.

In one incident, a company's smart HVAC system was compromised and used as a gateway to access the corporate network. The attackers managed to pivot from the HVAC system to the main network, ultimately leading to a significant data breach. This highlights the importance of securing even seemingly non-critical devices. (Ref: https://krebsonsecurity.com/2014/02/target-hackers-broke-in-via-hvac-company/?utm_source=chatgpt.com)

How to secure IoT devices:

• Network segmentation: Separate IoT devices from the main corporate network to limit the damage in case of a compromise.

• Change default credentials: Ensure all IoT devices have their default credentials changed and strong passwords implemented.

• Regular audits: Conduct regular security audits to identify and address vulnerabilities in IoT devices.

Deepfakes: The new era of social engineering

Deepfake technology is no longer a novelty; it has become a powerful tool in the hands of cybercriminals. Deepfakes are AI-generated audio or video content that can convincingly mimic real people. In 2024, deepfakes are increasingly being used for social engineering attacks, particularly targeting organizations for financial gain.

Imagine receiving a video call from your CEO instructing you to wire funds to a particular account—only it wasn’t your CEO at all. The ability to create realistic deepfake content has elevated the threat of Business Email Compromise (BEC) to a whole new level, making it a growing concern for cybersecurity teams.

A well-known incident involved an employee who received an urgent phone call from someone who sounded exactly like the CFO, instructing them to make a significant payment ( $243,000) to a vendor. The employee complied, only to later discover that it was a deepfake voice used by attackers to commit fraud.

How to protect against deepfake attacks:

• Multi-factor verification: Implement multiple layers of verification for financial transactions, including cross-checking via different channels.

• Employee training: Train employees to recognize the signs of deepfakes and to verify the authenticity of unusual requests.

• AI tools for detection: Use AI-based tools that can help detect manipulated audio and video content to identify deepfakes.

The skills gap in cybersecurity

While the threats are becoming more sophisticated, the pool of skilled cybersecurity professionals remains limited. The cybersecurity skills gap is a pressing challenge that makes defending against these emerging threats even harder. Organizations must adapt by building strong internal capabilities, investing in training, and leveraging automation.

Addressing the skills gap:

• Invest in training: Encourage existing IT staff to upskill in cybersecurity by providing training and certification opportunities. This not only fills critical gaps but also boosts employee retention.

• Leverage automation: Automation can help alleviate the burden on security teams by handling routine tasks like log analysis and vulnerability scanning, allowing skilled professionals to focus on high-priority threats.

• Partner with educational institutions: Build partnerships with universities and technical schools to create internships and co-op programs, bringing fresh talent into the organization.

Practical advice for executives and Cybersecurity leaders

1. Adopt a proactive security posture: Waiting until an incident occurs is no longer an option. Adopt a proactive approach by conducting regular penetration tests, threat hunting, and red team exercises.

2. Embrace zero trust: The Zero Trust model—never trust, always verify—is more relevant than ever. With IoT devices, remote work, and increased attack surfaces, ensuring that every connection is verified is essential.

3. Build a resilient incident response plan: Ensure that your incident response plan is well-documented, regularly tested, and includes strategies for handling AI, IoT, and deepfake-related threats.

4. Use AI defensively: While attackers are leveraging AI, defenders must do the same. Deploy AI-based solutions for threat detection, behavioral analysis, and automated responses to contain threats in real time.

The path forward

The emerging threats in 2024 are pushing the boundaries of what we traditionally think of as cybersecurity. AI, IoT, and deepfakes are not just buzzwords—they represent real, evolving threats that can disrupt businesses and compromise sensitive information. Organizations that understand these threats and adapt accordingly will be better positioned to protect their data, reputation, and bottom line.

Closing thought: The threat landscape in 2024 demands that we stay agile, proactive, and innovative. By investing in people, technology, and processes, we can navigate these emerging threats and ensure our organizations remain resilient in an increasingly complex digital world.
