5. Fraudulent Transactions

• Threat: Fraud in financial systems often involves manipulating transactions, which can lead to significant losses and damage to a company’s reputation.
• Solution: AI analyzes transaction patterns to flag suspicious activity in real time. By simulating fraud, AI helps systems become better at catching it before it causes harm.

6. Vulnerabilities in Software

• Threat: Software often has hidden flaws that hackers can exploit to access systems, steal data, or disrupt services.
• Solution: AI can identify these vulnerabilities and automatically apply patches to fix them, closing the door on attackers before they can cause trouble.

7. Deepfake Media

• Threat: Deepfakes are AI-generated images, videos, or audio that can impersonate real people, often used in scams or misinformation.
• Solution: AI can detect subtle inconsistencies in deepfake media, helping to prevent impersonation and manipulation. It adapts continuously, making it harder for attackers to fool people with fake media.

8. Zero-Day and Advanced Attacks

• Threat: Zero-day attacks exploit unknown software vulnerabilities, making them especially hard to prevent.
• Solution: AI can simulate possible attack scenarios, giving security teams a heads-up on potential threats. This proactive approach helps reduce the impact of advanced, unexpected attacks.

9. Social Engineering

• Threat: Social engineering tricks people into revealing sensitive information, often by playing on emotions or trust.
• Solution: Generative AI can simulate these manipulative tactics, training employees to recognize and resist them. This builds awareness and reduces the chances of falling for real social engineering schemes.

10. Staying Updated on New Threats

• Threat: Cyber threats constantly evolve, and staying updated on the latest tactics is a challenge for organizations.
• Solution: AI can generate synthetic data and realistic threat scenarios, keeping organizations informed about emerging attack methods and helping them prepare defenses in advance.
