What the 2025 IBM Data Breach Report Really Says?

The IBM Cost of a Data Breach Report has been published every year for two decades. It’s often read for the numbers, but this year’s report says something more fundamental about cybersecurity awareness.

The IBM Cost of a Data Breach Report has been published every year for two decades.

It’s often read for the numbers: the global average breach cost (now $4.4M), the top industries, or the fines (which in the U.S. push average costs to $10M).

But look a little deeper and with your own expert-view, and this year’s report says something more fundamental about cybersecurity awareness.

AI is already inside the breach

One in six breaches in 2025 involved AI.

And when AI was used, attackers reached for tools we all “know very well”:

  • 37% were phishing emails
  • 35% used deepfakes and impersonation

Phishing remains the dominant entry point. The difference is scale and realism. AI doesn’t replace old attack vectors – it makes them much stronger.

Governance is the missing piece

63% of organizations hit by an AI-related breach had no AI governance in place.

97% lacked access controls for AI tools.

This explains why “shadow AI” – employees experimenting with tools outside IT’s oversight – shows up so frequently in breach narratives. We’ve seen the same pattern before: adoption moves faster than security.

Recovery is harder than many admit

  • Two-thirds of organizations say they never fully recover from a data breach.
  • And 76% say recovery takes longer than 100 days.

These numbers put the focus on resilience — not just prevention. If most companies can’t bounce back quickly, the conversation has to shift toward how people react under attack.

Awareness needs practice, not more policies

The report’s numbers confirm what awareness professionals have long observed:

  • Attack vectors stay constant (phishing, compromised credentials, insider threats).
  • The environment around them evolves (AI, automation, fines, supply chains).

Human error is still the constant.

What changes is the context in which humans make mistakes.

That’s why traditional awareness (policies, lectures, slide decks) rarely works under real pressure. People know the rules — but fatigue, urgency, or a very convincing AI-crafted phish are enough to override that knowledge.

The answer is not more policies. It’s practice.

Realistic simulations. Adaptive coaching. Building instincts instead of relying on theory.

“The IBM report reminds me: awareness is not about knowing what phishing is. It’s about building the muscle memory to resist it – even when the phish looks perfect.”

A joint study with Lucerne University on AI-enabled spearphishing

Event card "AI-enabled spearphishing" by Dr. Carlo Pugnetti, Lucerne University, October 1st, over Lucerne's Chapel Bridge

In collaboration with Lucerne University, CYBERDISE conducted a controlled study to examine how employees respond to AI-enabled spearphishing attacks. Unlike traditional phishing, these attacks are personalized, adaptive, and more difficult to detect.

The research reveals a clear finding: Participants trained with CYBERDISE demonstrated a 60% increase in vigilance when facing AI/OSINT-generated spearphishing attempts. In this webinar, we will present the study design, key results, and implications for organizations that want to stay ahead of evolving threats. You’ll learn: – How AI is reshaping the landscape of spearphishing. – The methodology and findings from our joint study with Lucerne University. – Why human vigilance remains a major vulnerability in cybersecurity. – Practical advice to strengthen awareness programs based on scientific evidence.

How many breaches in 2025 involved AI?
One in six breaches in 2025 involved AI. When AI was used, 37% were phishing emails and 35% used deepfakes and impersonation.
Does AI replace old attack vectors?
No. AI doesn’t replace old attack vectors – it makes them much stronger. Phishing remains the dominant entry point; the difference is scale and realism.
Why does shadow AI show up so often in breach narratives?
Because governance is missing: 63% of organizations hit by an AI-related breach had no AI governance in place, and 97% lacked access controls for AI tools. Shadow AI means employees experimenting with tools outside IT’s oversight – adoption moves faster than security.
How long does recovery from a data breach take?
76% of organizations say recovery takes longer than 100 days, and two-thirds say they never fully recover from a data breach.
Why does traditional awareness rarely work under real pressure?
People know the rules, but fatigue, urgency, or a very convincing AI-crafted phish are enough to override that knowledge. That’s why traditional awareness (policies, lectures, slide decks) rarely works under real pressure.
If not more policies, what is the answer?
Practice: realistic simulations, adaptive coaching, and building instincts instead of relying on theory.
How does AI-enabled spearphishing differ from traditional phishing?
Unlike traditional phishing, AI-enabled spearphishing attacks are personalized, adaptive, and more difficult to detect.
