The Verizon 2025 Data Breach Investigations Report (DBIR) has drawn a red line through conventional cybersecurity thinking. This year, it wasn’t sophisticated malware or high-profile zero-day attacks that took center stage — it was the overlooked fundamentals: third-party risk and machine identity governance.
In an era where organizations are more connected, automated, and reliant on digital ecosystems than ever, the real threat isn’t always a new exploit — it’s the unmonitored access granted to machines and external users. As AI agents and machine accounts proliferate, they introduce complexity and exposure that most enterprises aren’t prepared to handle. The DBIR outlines a harsh truth: fragmented identity governance is no longer a minor flaw; it’s a direct path to breach.
The Expanding Attack Surface: A 30-Line Summary
The 2025 DBIR revealed a sharp increase in third-party-related data breaches, rising from 15% to 30% year-over-year.
The majority of these incidents stemmed from poor identity lifecycle management of external accounts.
Industries affected include healthcare, finance, manufacturing, and public services — showing this is a universal problem.
Contractors, vendors, and partners are now common entry points for threat actors.
A key issue is inactive or over-privileged accounts that are not deactivated after usage.
Simultaneously, ungoverned machine identities — bots, APIs, AI agents, RPAs — are being exploited at scale.
Attackers are increasingly targeting machine credentials for initial access and privilege escalation.
Machine identity governance is lagging behind human identity controls, creating severe blind spots.
Traditional identity management tools treat machine accounts as second-tier priorities.
Many machine accounts lack clear ownership or oversight.
The proliferation of AI agents is expected to further accelerate machine identity growth.
Without automated and scalable governance, machine accounts become high-risk liabilities.
Credential abuse is now one of the top methods used by attackers to breach systems.
Fragmented identity strategies make it easier for attackers to find a single weak point.
Siloed governance between employees, partners, and machines is no longer viable.
Identity is now the true perimeter of security — not just networks or endpoints.
Unified identity governance must extend across human, third-party, and machine users.
Gaps in identity visibility result in undetected privilege abuse and unauthorized access.
A successful breach today often originates from a forgotten third-party login or service account.
Automated de-provisioning and continuous monitoring are essential to reduce risk.
Effective security requires clarity — not complexity — in managing all forms of identity.
Organizations must treat machine identities with the same rigor as employee accounts.
AI-driven identity models need to be incorporated for real-time risk detection.
The report emphasizes that identity chaos translates directly into breach opportunities.
Machine and non-employee accounts should have enforced least privilege and activity logging.
Threat actors are pivoting toward less-monitored access points in the identity stack.
Unified identity platforms like SailPoint are responding with end-to-end visibility.
Machine identity-specific governance models are becoming a necessity, not a luxury.
The push for identity-first security strategies is now mission-critical for breach prevention.
The takeaway: modern threats require unified, intelligent, and proactive identity management.
What Undercode Say: A Deep Analysis on Machine and Third-Party Identity Risk
The rise of machine identity abuse signals a dramatic shift in the threat landscape. In the past, attackers targeted weak passwords, open ports, or unpatched systems. Now, the path of least resistance is identity — and especially those identities no one is watching. The 2025 DBIR’s findings align with what many cybersecurity professionals have witnessed but struggled to quantify: that machine accounts and third-party credentials are the new weak links in the chain.
Here’s what we find most critical about the
Third-Party Identity Risk is Scaling Faster than Controls: As organizations embrace digital transformation, they also open the floodgates to external partners. Without automated identity governance, many fail to remove or monitor these access points. This neglect is now manifesting in real breaches across nearly every industry.
Machine Identity Management is the Next Cyber Battleground: Enterprises are scaling AI-driven processes, microservices, and automated workflows faster than they’re governing the identities enabling them. As a result, attackers are finding goldmines of unprotected machine credentials — often with powerful access rights.
Traditional IAM is Outdated for Today’s Needs: Many companies still rely on outdated human-centric identity models that ignore the explosion of service accounts and non-human actors. These legacy frameworks create a governance vacuum that cybercriminals are eager to exploit.
AI Agents Will Worsen the Problem Before It Gets Better: The rise of generative AI and autonomous systems will introduce thousands of new identities per organization. Without identity lifecycle automation and behavioral analytics, these agents will operate in the shadows, uncontrolled and invisible.
Lack of Ownership Means Lack of Accountability: Machine identities often don’t belong to a person — they belong to systems, applications, or scripts. Without clear ownership, these accounts escape standard security reviews, logging, and access audits.
Unified Identity Security is No Longer Optional: Disjointed identity policies lead to gaps. Unified platforms that centralize human, machine, and third-party identity governance are now vital to prevent lateral movement and privilege escalation.
Credential Abuse is the First Step in Most Modern Breaches: Attackers rarely use brute force anymore. Instead, they search for under-governed service accounts or third-party credentials to sneak into systems. Once inside, privilege escalation follows.
Lifecycle Management is the Hidden Hero: Timely deactivation of machine and third-party accounts is among the simplest yet most neglected defenses. Automating this process across all identity types reduces unnecessary exposure.
Zero Trust Requires Identity Intelligence: Implementing Zero Trust without deep identity visibility is just wishful thinking. A real Zero Trust model must include machine and third-party risk scoring, context-aware access controls, and dynamic identity behavior analytics.
Identity is the New Perimeter — and the Most Fragile One: Network and endpoint security are no longer sufficient. Identity, and specifically identity behavior, must be the central focus of every organization’s defense architecture.
In short, as organizations accelerate their digital ecosystems, attackers aren’t following complexity — they’re exploiting simplicity. A forgotten vendor login or unmonitored service account can now open the door to a full-scale breach. Undercode’s stance is clear: the war on cybercrime will be won not by firewalls or signatures, but by who manages identity better.
Fact Checker Results
Third-party involvement in breaches doubled from 15% to 30% — Verified in the 2025 DBIR.
Credential-based attacks remain a top initial access method — Confirmed by multiple threat intelligence sources.
Machine identities often lack governance — Supported by industry whitepapers and incident reports.
Prediction
The next wave of cybersecurity breaches will stem not from headline-grabbing zero-days, but from the unchecked sprawl of machine and third-party identities. By 2027, expect over 60% of enterprise breaches to originate from non-employee or machine accounts. Enterprises failing to adopt unified, automated identity governance will be left exposed, while those prioritizing intelligent identity management will gain a competitive edge in both security and operational resilience.
