AI-driven attacks rose 56% in a year, adding $1M to the average $4.99M breach cost. U.S. companies paid $11.5M. Healthcare, financial, and energy sectors lead the damage.
Alpha Score of 47 reflects weak overall profile with weak momentum, moderate value, weak quality, moderate sentiment.
The average cost of a data breach hit a record $4.99 million, a 12% increase over last year, as attackers weaponized AI at a pace that outstrips most corporate defenses.
AI-driven attacks jumped 56% from the prior year's study, adding roughly $1 million to the average breach tab, according to IBM's Cost of a Data Breach Report. The research, conducted by Ponemon Institute, covered 602 organizations hit between March 2025 and February 2026 and included interviews with more than 3,550 security and C-suite leaders.
"What's changing is the economics of cyberattacks. AI is making attacks faster and cheaper, while breaches keep getting more expensive," said Suja Viswesan, vice president of IBM Security Software. "When organizations have an extended gap between discovery and remediation, that imbalance shows up directly in breach costs."
Ninety-two percent of organizations that suffered an AI-related breach lacked proper access controls for AI systems, the report found. Despite that, 85% of breached organizations said they plan to increase spending on security tools and governance.
IBM said three-quarters of organizations surveyed will deploy AI agents at higher rates in alert triage, vulnerability management, and penetration testing.
The U.S. posted the highest average breach cost at $11.5 million, roughly double the global average, driven by higher business costs and regulatory fines. Healthcare remained the most expensive sector at $6.4 million per breach, though that figure was down from $7.4 million a year earlier. Financial services averaged $6.3 million; energy came in at $5.2 million.
Malicious or criminal attacks accounted for 55% of all breaches, up nearly 8% from last year and more than double the share caused by IT failures or human error.
IBM's stock page carries an Alpha Score of 37 out of 100, a Mixed label in the Technology sector, reflecting the competing pressures of rising cyber spending demand and the company's own exposure to a fast-changing threat landscape.
