Reflecting on Last Year’s Predictions (2024)

Before diving into what lies ahead, let’s take a quick look back. In 2024, several noteworthy trends took center stage, and nearly all came true in one form or another. By understanding these developments, you can better contextualize and prepare for the more sophisticated threats of 2025 and beyond.

Passkeys and the End of Passwords

One of last year’s primary predictions was the mass adoption of passkeys—cryptographically secure, user-friendly alternatives to traditional passwords.

• Notable Milestone: A major password management provider reported 4.2 million passkeys were saved in its vaults over the past year.
• Rapid Growth: They also noted that 1 in 3 users have begun storing and presumably using passkeys, marking a real shift in everyday security practices.
• Future Outlook: As more websites and apps adopt the FIDO Alliance standards, expect a steady decline in traditional password reliance.

Why This Matters
Passkeys are both more secure and more convenient than passwords. For businesses, this means less overhead for password resets and fewer vulnerabilities due to weak or reused credentials.

AI-Driven Phishing Attacks

Generative AI has made phishing emails more realistic and targeted than ever:

• Perfect Grammar and Style: The days of spotting scams through awkward English are gone. Attackers now use advanced AI models to write flawlessly.
• Personalized Content: AI tools can scrape public information, tailoring emails that feel legitimate and highly specific to the recipient.
• Wider Impact: An email security firm reported phishing emails with near-perfect authenticity, making it harder for employees to distinguish friend from foe.

Defensive Strategy

• Deploy email security solutions with machine learning capabilities to detect anomalies.
• Continually train employees to question even well-written messages that make unusual requests or include suspicious links.

Deepfakes Gone Mainstream

Deepfake technology isn’t a future threat—it’s here now:

• Corporate Swindles: Soon after the 2024 predictions video was released, a CFO’s deepfaked likeness convinced an employee to transfer $25 million to an attacker’s account.
• Election Interference: In the early run-up to the 2024 U.S. presidential election, a deepfake robo-call of Joe Biden’s voice told voters they didn’t need to participate in a primary, sowing significant confusion.
• Growing Concern: These examples prove that audio and video manipulation can easily deceive both private citizens and well-trained professionals.

Looking Forward
Businesses must devise verification protocols, especially for significant transactions or high-level communications. Deepfakes also raise legal concerns—if video evidence can be fabricated, how will courts authenticate digital proof?

Hallucinations in Generative AI

Even as AI gets smarter, hallucinations—instances where AI confidently provides inaccurate information—remain a challenge:

• Real-World Example: An AI chatbot incorrectly converted a 5.45 min/km running pace to 3.43 min/mile, implying a world-record-breaking speed. When challenged, it recalculated to 9.15 min/mile, a stark difference.
• Implications: Businesses relying on AI for critical tasks should be aware that not all AI outputs are gospel. Ongoing human oversight is essential.

Securing AI Deployments

AI deployments themselves need robust cybersecurity measures:

• Top Client Concern: Organizations integrating AI want to ensure these systems are not easily exploited or tampered with.
• Confidential Data Risks: Models can inadvertently expose sensitive data if not properly secured or if “prompt injection” vulnerabilities are exploited.

Using AI to Strengthen Cyber Defenses

On the flip side, AI offers tools to improve cybersecurity:

• Case Summaries: Generative AI excels at summarizing lengthy documents. Security analysts can swiftly review incident histories or threat reports.
• Enhanced Q&A: Retrieval-augmented generation (RAG) can create chatbots that answer internal security questions accurately—provided the underlying data is properly managed and validated.

Cybersecurity Trends for 2025 and Beyond

Now, let’s dust off the crystal ball again. While Artificial Intelligence will continue to be a key driver—for better or worse—there are additional challenges and game-changers on the horizon.

1. Shadow AI: The New Frontier of Risk

As AI tools become more accessible, not all deployments will be authorized or well-managed:

• Unapproved Deployments: Employees might spin up AI instances in the cloud or install unauthorized apps on their devices, bypassing IT oversight.
• Data Leakage: Sensitive or proprietary information can slip through these shadow systems, leading to compliance violations or reputation damage.
• Mobile OS Integration: AI is increasingly integrated into smartphones, raising concerns about how data from these tools is stored and shared.

What You Can Do
Implement strong governance policies around AI usage. Educate your workforce on the risks of unauthorized tools and monitor for unapproved AI-driven activities.

2. Deepfakes 2.0: Business, Government, and Legal Implications

Deepfake technologies are only getting better, with wide-ranging impact:

1. Business Fraud
   • A previously documented example involved $25 million stolen. Another case saw $35 million transferred due to a well-crafted audio impersonation.
   • Verification Protocols: For high-stakes transactions, require multi-factor approval and out-of-band authentication.
2. Government & Elections
   • Deepfake robo-calls or videos can manipulate public opinion.
   • Trusted Sources: Encourage citizens to rely on official websites or verified social media channels for important announcements.
3. Legal Challenges
   • Authentic-looking footage of crimes or statements could undermine court evidence.
   • Conversely, real footage might be dismissed as a deepfake, introducing reasonable doubt in trials.

3. AI-Powered Exploits and Malware

Criminals now use generative AI not just for phishing but also to write malicious code:

• Rapid Exploit Generation: A study showed that a large language model produced exploit code for zero-day vulnerabilities in 87% of tested scenarios.
• No Coding Skills Needed: Attackers only need a basic understanding of the vulnerability to prompt AI effectively.
• Skyrocketing Attacks: One major online retailer witnessed a sevenfold increase in attacks over the last six months—likely linked to AI’s ability to automate malicious processes.

Defensive Measures

• Harden your systems by promptly patching known vulnerabilities.
• Use intrusion detection/prevention systems (IDS/IPS) that can flag unusual network activity in real time.

4. Expanding Attack Surfaces in the AI Era

Each new AI tool or system you add becomes a potential attack vector:

• Shadow AI Impact: Unauthorized deployments can connect to your organization’s network, broadening the attack surface.
• Model Poisoning: Hackers might insert malicious data into AI training sets, causing the model to misbehave or leak data.

Action Item
Regularly inventory all AI instances and ensure you have robust monitoring and patching strategies for each.

5. Prompt Injection: The Top Threat to Large Language Models

Generative AI models are vulnerable to social engineering—similar to humans:

• Prompt Injection Attacks: Attackers trick AI into performing actions or revealing data outside its intended scope.
• OWASP Priority: The Open Worldwide Application Security Project (OWASP) lists prompt injection as the number-one threat to large language models.
• Why It Matters: Malicious prompts can override guardrails, leading to unauthorized data exposure or harmful recommendations.

Preventive Tips

• Implement content filtering and context restrictions.
• Regularly test your AI models with “red team” exercises to identify vulnerabilities.

6. AI-Assisted Cybersecurity: From Analysis to Response

AI won’t only be used by attackers. It’s also a powerful defensive ally:

• Incident Summaries: AI tools can collate logs, identify indicators of compromise, and produce quick, accurate summaries for human analysts.
• Recommended Remediation: While full automation is risky—due to the risk of AI “hallucinations”—AI suggestions can speed up manual response times.
• 24/7 Monitoring: AI-enabled systems can watch your network constantly, raising red flags the moment anomalies appear.

Balancing Act
Use human-in-the-loop mechanisms. Let AI handle data parsing, but ensure experienced security professionals make final decisions.

7. Quantum Computing and Post-Quantum Cryptography

Finally, quantum computing is poised to revolutionize cryptography:

• Threat to Encryption: Quantum machines can theoretically break current public-key cryptography, potentially exposing everything from financial data to top-secret intelligence.
• Harvest Now, Decrypt Later: Attackers may already be collecting encrypted data, with plans to decrypt once quantum capabilities mature.
• Quantum-Safe Algorithms: Researchers are developing algorithms resistant to quantum attacks, often called post-quantum cryptography (PQC).

Immediate Steps

• Begin migrating critical systems to quantum-safe algorithms.
• Monitor official guidance from bodies like NIST (National Institute of Standards and Technology) on recommended cryptographic standards.

Key Takeaways and Action Steps

1. Adopt Modern Authentication
   • If you haven’t moved toward passkeys, make it a priority.
2. Train, Train, Train
   • Equip your employees to recognize sophisticated phishing and deepfakes.
3. Establish AI Governance
   • Formalize policies to control Shadow AI and prevent data leakage.
4. Stay Vigilant on AI Model Security
