TL;DR: Credential abuse appeared in 39% of full breach chains, and 50% of ransomware victims saw a credential or infostealer event within 95 days, according to Acsense citing Verizon's 2026 DBIR, which analyzed more than 22,000 confirmed breaches. Identity controls now shape both intrusion paths and recovery cost.
Editorial analysis by NHI Mgmt Group, based on content published by Acsense: “Verizon DBIR 2026: What It Means for IAM Resilience”.
By the numbers:
- The 2026 DBIR analyzed over 22,000 confirmed breaches across 145 countries.
- Credential abuse remained the single most pervasive technique at 39% across full breach chains.
- Ransomware hit 48% of breaches in the 2026 DBIR.
Key questions
Q: What breaks when identity visibility is missing during a ransomware attack?
A: Containment becomes guesswork.
Q: Why do compromised credentials so often lead to broader access after initial login?
A: Compromised credentials often become a foothold because attackers inherit the targeted user’s trust, network reach, and authentication context.
Q: How can organisations prove that identity controls support resilience?
A: By showing that access governance still holds during disruption, that audit trails are complete, and that recovery processes restore control quickly.
Practitioner guidance
- Audit identity recovery dependencies Map which IAM tenants, policy objects, admin roles, and federation settings must be restored before business systems can authenticate again.
- Tighten third-party and admin MFA hygiene Find cloud and external identities with missing or disabled MFA, then track remediation as a closure programme rather than a one-off ticket queue.
- Treat infostealer exposure as a ransomware precursor Correlate stolen credential telemetry with privileged identity assets so the response starts before an attacker reaches tenant-wide control.
Bottom line: Credential abuse remains a major breach-chain problem because it carries attackers beyond initial access into persistence and escalation.

Credential abuse is now a breach-chain property, not just an access vector. The DBIR's 39% figure should be read as evidence that stolen credentials continue to matter after initial entry, not only at the door. That changes the governance problem for IAM teams because the same identity can support persistence, lateral movement, and recovery disruption. The implication is that credential lifecycle control has become a cross-stage control, not a point-in-time check.
A few things that frame the scale:
- Credential abuse across the entire attack chain, not just initial access, appears in 39% of all breaches, according to the 2026 Verizon Data Breach Investigations Report.
A question worth separating out:
Q: Should security teams treat NHIs and human admin accounts under the same recovery plan?
A: Yes, because the recovery dependency is the same even if the actor type differs. Service accounts, API keys, OAuth links, and human admins all sit inside the authentication path. A recovery plan that ignores NHIs leaves part of the tenant unrecoverable when a breach hits.
