TL;DR: The 2026 Verizon DBIR analyzed more than 31,000 security incidents and found that exploitation of vulnerabilities is now the leading initial access vector, while credential abuse still drives a large share of attacks and ransomware chains, according to Enzoic’s summary of the report. The message for identity teams is that patching and credential control remain the practical choke points, not abstract security goals.
NHIMG editorial — based on content published by Enzoic: analysis of the 2026 Verizon DBIR, credential abuse, and vulnerability exploitation trends
By the numbers:
- Only 26% of the CISA KEV vulnerabilities had been fully remediated, a considerable drop from last year’s 38%.
- The median number of KEV vulnerabilities that had to be patched by organizations has risen in 2025 to 16, where this figure was 11 in 2024.
- The analysis found that 27% of ransomware victims had no associated infostealer or credential leak occur within the year.
Questions worth separating out
Q: What breaks when stolen credentials are still valid after exposure?
A: When stolen credentials remain valid, attackers do not need to bypass authentication again.
Q: Why do credential attacks still matter in environments with MFA?
A: MFA reduces some forms of credential abuse, but it does not eliminate all attacker paths.
Q: How do security teams know whether credential controls are actually working?
A: They should look for fewer successful logins from known compromised credentials, lower rates of password reuse, shorter time between exposure and revocation, and reduced lateral movement from initial access accounts.
Practitioner guidance
- Harden credential replay resistance Enforce unique passwords, blacklist known compromised passwords, and require MFA wherever it is supported so stolen credentials have less operational value.
- Shorten the life of exposed access paths Review any password, token, or API key that can be reused across multiple systems and reduce its usable lifetime through rotation, revocation, or narrower scope.
- Tie patching to access risk Prioritise internet-facing vulnerabilities that can lead to authentication bypass, code execution, or credential theft before they become identity incidents.

Credential abuse in the 2026 DBIR: what IAM teams need to act on?
Explore further
Credential persistence is the real failure mode behind modern intrusion chains. The report shows that attackers do not need novel identity techniques when valid credentials remain reusable after exposure. That is a governance failure, not just a detection failure, because identity programmes still tolerate credentials that outlive the conditions under which they were issued. The practitioner conclusion is blunt: if compromise does not quickly invalidate access, identity becomes the attacker’s persistence layer.
A few things that frame the scale:
- 72% of organisations have experienced or suspect they have experienced a breach of non-human identities, according to The 2024 ESG Report: Managing Non-Human Identities.
- Enterprises that have experienced a compromised NHI averaged 2.7 separate incidents in the past 12 months, according to The 2024 ESG Report: Managing Non-Human Identities.
A question worth separating out:
Q: Who is accountable when exposed credentials lead to a breach?
A: Accountability usually spans IAM, infrastructure, application owners, and security operations because the failure often crosses multiple controls. The key question is who owns the credential lifecycle, who can revoke it quickly, and who is responsible for the systems that accept it. Without named ownership, exposed access becomes everyone’s problem and no one’s control.
