TL;DR: Credential abuse remains the most common breach vector, with attackers increasingly using stolen, reused, or exposed usernames and passwords to gain legitimate access and prolong dwell time, according to Enzoic and Verizon’s 2026 Data Breach Investigations Report. Point-in-time password policy is no longer enough because exposure can happen long after creation, making continuous credential visibility a core underwriting and IAM concern.

By the numbers:
- 80 to 85 percent of users reuse passwords across multiple personal and professional accounts.
- 97 percent of the identity attacks it observed involved password spraying.
Questions worth separating out
Q: How should security teams reduce cyber insurance risk from credential abuse?
A: They should focus on reducing the chance that stolen or reused credentials can be used successfully and on shrinking the impact if they are.
Q: Why do valid credentials create more underwriting concern than many other attack paths?
A: Because they let attackers look like legitimate users.
Q: What do organisations get wrong about breached password risk?
A: Many teams treat breached passwords as an edge case instead of a standing control weakness.
Practitioner guidance
- Implement continuous credential exposure monitoring Track stolen, reused, and breached credentials across the lifecycle so remediation can begin before attackers exploit them.
- Reduce password reuse across business-critical accounts Enforce unique credentials for employees, contractors, and privileged users, and pair the control with detections for credential stuffing and password spraying.
- Tighten privileged access review for high-value identities Review cloud console access, admin accounts, and service-linked credentials on a shorter cycle than standard user access, and remove unnecessary standing privilege.
What's in the full article
Enzoic's full article covers the operational detail this post intentionally leaves for the source:
- How credential abuse affects cyber insurance underwriting questions and claim severity assessments.
- The practical role of MFA, PAM, and identity governance in reducing insurer-perceived risk.
- Why point-in-time password policies miss post-issuance exposure and how continuous visibility changes that.
- How organisations can frame identity controls as evidence of resilience during renewal conversations.

Credential exposure is now a governance problem, not a password problem. This article is really about the failure of point-in-time identity assurance. Once credentials can be replayed, sold, or harvested after issuance, the governance question becomes how quickly exposure is detected and revoked, not whether a password met policy at creation. Practitioners should treat credential exposure as a lifecycle state, not a one-time event.
A few things that frame the scale:
- Two-thirds of enterprises have endured a successful cyberattack resulting from compromised non-human identities, with a quarter encountering multiple attacks, according to The 2024 ESG Report: Managing Non-Human Identities.
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, with 46% confirmed and 26% suspected.
A question worth separating out:
Q: Who is accountable when privileged access failures affect a cyber insurance claim?
A: Accountability usually sits with whoever owns access governance, security operations, and the system that granted or retained the privilege. In practice that often spans IAM, PAM, platform teams, and business owners. If no one can produce evidence quickly, the organisation inherits both operational and financial exposure.
