vulnerability exploitationtechnical
"for the first time in 19 years of the DBIR being published, exploiting vulnerabilities has surpassed"
Vulnerability exploitation is the act of taking advantage of a weakness in a computer system, software, or network to gain unauthorized access, disrupt operations, or steal information. For investors it matters because successful attacks can cause direct financial losses, halt business operations, damage customer trust and trigger regulatory fines—similar to a criminal finding and using an unlocked door to break into a storefront, the resulting harm can reduce a company's revenue and valuation.
data breach investigations reporttechnical
"The 19th edition of the Data Breach Investigations Report (DBIR) confirms AI-driven speed"
A data breach investigations report is a document that summarizes what went wrong when sensitive information was exposed, how the breach occurred, which data was affected, and what steps were taken to stop it and prevent a repeat. For investors it functions like a post‑accident report: it reveals potential legal costs, regulatory fines, lost customer trust, and required fixes that can affect a company’s future earnings and risk profile.
social engineeringtechnical
"threat actors are pivoting to mobile-centric social engineering (fake text messages and voice calls)"
Social engineering is the practice of manipulating people into revealing confidential information, granting access, or taking actions that compromise security, often by posing as a trusted person or using urgent, persuasive stories. For investors it matters because these scams can lead to direct financial loss, theft of sensitive corporate data, disrupted operations, or damage to a company’s reputation — similar to a con artist who tricks a business into handing over its keys.
shadow AItechnical
"Shadow AI, referring to employees using unapproved AI tools at work, is now the third most common"
Shadow AI describes employees using artificial intelligence tools or services without formal approval, oversight, or integration into official systems — for example, personal subscriptions, free web apps, or browser add-ons. For investors this matters because these hidden tools can expose sensitive data, create compliance or legal problems, produce unreliable results, and lead to unexpected costs or reputational damage, much like an unapproved gadget in a factory that creates safety and billing surprises.
data exfiltrationtechnical
"highlighting an elevated risk of data exfiltration associated with unapproved platforms."
Data exfiltration is the unauthorized copying or removal of sensitive information from an organization’s systems, like someone sneaking files out of a locked office. It matters to investors because stolen data can lead to direct financial loss, regulatory fines, legal liability, damage to customer trust, and operational disruption — all of which can reduce revenue and share value and create unpredictable costs for the company.
ai bot internet crawlerstechnical
"AI Bot Internet Crawlers are experiencing a massive 21% month-over-month growth"
AI bot internet crawlers are automated programs that use artificial intelligence to browse, read and extract information from websites at large scale, acting like a digital librarian that scans pages to pull out text, images and data. They matter to investors because they can speed up market research and competitive monitoring but also create risks—such as inaccurate or misused data, strain on a company’s web infrastructure, copyright or privacy disputes, and shifts in web traffic or revenue models—that can affect a business’s costs, reputation and regulatory exposure.
secure by designtechnical
"integrating AI into 'secure by design' frameworks, and leveraging AI within defense-in-depth"
An engineering approach that builds security into a product, system, or process from the very beginning rather than bolting it on later. For investors, it matters because solutions designed this way tend to have fewer costly breaches, lower remediation and compliance expenses, and a stronger reputation—similar to installing a safe during construction instead of adding locks after a break-in, which helps protect long-term value and predictable risk.
defense-in-depthtechnical
"integrating AI into 'secure by design' frameworks, and leveraging AI within defense-in-depth strategies"
A strategy of layered safeguards that combines multiple, different controls to prevent failures, breaches or accidents. Like a series of locked doors, alarms and backup plans protecting the same asset, each layer reduces the chance that a single problem becomes a crisis; for investors, clear defense-in-depth means management is actively lowering operational, cybersecurity and regulatory risk, which can protect earnings, reputation and long-term value.
The 19th edition of the Data Breach Investigations Report (DBIR) confirms AI-driven speed as a new challenge, pushing security strategy toward fundamental resilience
NEW YORK, May 19, 2026 (GLOBE NEWSWIRE) -- Verizon published the annual Data Breach Investigations Report (DBIR) today, which shows how Artificial Intelligence (AI) is impacting the cyber threat landscape as a whole. Although this report uses 2025 data—predating the latest frontier model advancements—the trends are clear: AI is fundamentally reshaping the cybersecurity industry. And at the same time that AI-detected vulnerabilities are in the news, for the first time in 19 years of the DBIR being published, exploiting vulnerabilities has surpassed stolen credentials to become the number one breach entry point.
Key Findings:
Nearly a third (31%) of all breaches start with vulnerability exploitation in an AI world: This is the first time in 19 years that it has surpassed stolen credentials as the biggest point of entry. Further, AI is being leveraged by threat actors to accelerate the time to exploit known vulnerabilities, shrinking the window for defense from months to mere hours.
Interactive, conversational attacks on mobile are on the rise: In terms of the “Human Element” risk of cybersecurity, as people get more savvy about traditional email phishing, threat actors are pivoting to mobile-centric social engineering (fake text messages and voice calls) with a success rate 40% higher than traditional email phishing.
More employees now use ‘shadow AI’ at work, risking company secrets: Shadow AI, referring to employees using unapproved AI tools at work, is now the third most common non-malicious data leakage related activity. Frequent usage of AI tools by employees has surged from 15% to 45% of employees in a single year, highlighting an elevated risk of data exfiltration associated with unapproved platforms.
Supply chains get riskier as third-party involvementin breaches is up 60%: As companies rely more heavily on external vendors, threat actors are exploiting those vulnerabilities, with breaches involving a third party now accounting for 48% of all breaches.
AI Bots are the next frontier: AI Bot Internet Crawlers are experiencing a massive 21% month-over-month growth compared to entirely flat (0.3%) human-led traffic growth, showing where the next set of threats could come from.
What it means:
The rapid weaponization of known vulnerabilities by AI can create a capacity crisis for security teams, underscoring the urgent need to prioritize fundamental security and risk management practices. In response, the DBIR is providing Chief Information Security Officers (CISOs) and cybersecurity professionals with actionable, resilient recommendations tailored with today’s AI environment in mind throughout the report. These include preparing for an influx of patches as AI identifies software flaws at an accelerating rate, integrating AI into 'secure by design' frameworks, and leveraging AI within defense-in-depth strategies to minimize the total attack surface
"While the velocity of cyber threats - driven by AI and faster vulnerability exploitation - is increasing, the foundational principles of security and strong risk management remain the most effective defense," said Daniel Lawson, SVP Global Solutions, Verizon Business. "The DBIR reinforces that these fundamentals still hold as organizations strive for resilience."
