Why 2025 Might Be the Most Volatile Year Yet for Cybersecurity and What We Can Do About It

Oct 22 / TACRAVEN CYBER TEAM

Hello and welcome, let’s dive into what’s really going on in the cybersecurity right now.

Spoiler alert: It’s moving faster than ever!

1. The AI Arms Race: Not Just for Software Developers Anymore

We’ve all heard about artificial intelligence (AI) transforming everything but here's the twist: it’s not just about companies using AI for good. The bad guys are using it too. According to multiple recent reports, AI-driven malware and phishing campaigns are gaining steam.

For example, AI can mimic writing styles, create deepfake voices and videos, craft highly personalized phishing emails, and even adapt malware to avoid detection.  For the defenders (that’s you and me), this means our old playbook won’t always cut it.

What you can do:

  • Treat AI as both a weapon and a tool. When you're deploying AI-driven defenses, assume attackers may also be deploying AI.

  • Invest in anomaly detection, behavior-based monitoring, and threat intelligence that considers AI-driven threats.

  • Train users. If an email sounds “just like your boss,” but you aren’t expecting it pause and double-check.

2. Supply Chain and Third-Party Risk: The Ripple Effect Keeps Growing

It’s no longer sufficient to secure just your systems. The network effect of supply chains, vendor relationships, and tool dependencies means your weakest link might be someone else’s unsecured system.

We’ve seen attackers exploit software libraries, vendor updates, and third-party integrations. One compromised partner can cascade into your world.

What to keep in mind:

  • Conduct rigorous vendor risk assessments, and insist on security standards and audits.

  • Maintain visibility and access control over what third parties can touch within your environment.

  • Understand your “blast radius” if a vendor goes down, how many of your systems are impacted?

3. Encryption Under Threat: Quantum Is Looming (But It’s Not Here … Yet)

Yep “post-quantum cryptography” is no longer sci-fi. It’s on the radar for serious cybersecurity planners. A powerful quantum computer could someday crack many of today’s encryption schemes. And while quantum computers capable of breaking encryption are not mainstream (yet), adversaries are already harvesting encrypted data now to decrypt later. 


Action items:

  • Start inventorying what data you have that must remain secure for years.

  • Monitor standards and initiatives around post-quantum cryptography (PQC).

  • Consider hybrid encryption models and real-world risk around encryption lifespans.


4. Identity Is the New Perimeter – Treat It As Such

The days when you trusted from within a network boundary are mostly gone. Modern environments are hybrid, remote, cloud-based, and filled with connected devices. That means identity = access = risk.

If “who can do what” is blurry or uncontrolled, you’ll have trouble containing a breach.

Recommended steps:

  • Embrace zero-trust models: never trust, always verify, assume breach.

  • Strengthen identity fabrics: multifactor authentication, least-privilege, role-based access.

  • Monitor identity activity, especially for anomalous patterns (e.g., login from new geo, odd hours, unfamiliar device).

5. Regulation & Public Infrastructure: Stakes Are Getting Higher

The regulatory landscape is heating up. From public disclosure of cyber incidents to tighter rules on critical infrastructure, the pressure is mounting.

At the same time, digital infrastructure from OT (operational technology) to IoT devices in buildings and factories is being targeted more aggressively. 

What this means:

  • Compliance isn’t optional. If you’re subject to regulation (or your vendors are), make sure you stay ahead of requirements.

  • Critical infrastructure isn’t just “big utilities” anymore. Hackers are eyeing building systems, HVAC, cameras, sensors everything. Know what you’ve got and how it’s secured.


6. Human Factors: The Most Under-Normalized Risk

We talk about AI, quantum, zero-trust … but at the end of the day, humans remain the pivot point. The attacker often just needs one person to click, mis-configure, or let in the bad actor.

In 2025, workforce diversity, training, and cyber-awareness are rising as essential parts of cybersecurity strategy.

Quick wins:

  • Make training real. Use realistic phishing simulations, social-engineering exercises, not just “check-the-box” modules.

  • Empower your workforce to question. If something seems off, let them escalate without fear.

  • Build a culture of “cyber hygiene” regular updates, strong passwords (or passkeys), vigilance.

Final Thoughts

If I had to sum up 2025 in one line: “Complexity is the enemy of security, and we’re entering an era defined by new complexity.” Between AI, supply chains, quantum threats, identity chaos, regulatory pressure, and human fallibility the terrain is shifting beneath our feet.

But here’s the silver lining: awareness is half the battle. By recognizing these trends and taking pragmatic steps today, organizations can be ahead instead of trying to catch up tomorrow.

For the folks at TacRaven ThreatScope Blog, my ask is simple: don’t wait. Pick one of these areas (say, vendor risk or identity controls or AI threat detection) and make it a priority this quarter. Because the adversary isn’t waiting.
