TL;DR: Identity-based attacks now rely on valid credentials in three out of four breaches, while phishing, credential stuffing, AiTM, and exposed secrets continue to widen the entry surface, according to Zero Networks and cited breach research. The core issue is not only access loss but the assumption that identities remain stable long enough for reactive controls to matter.
Editorial analysis by NHI Mgmt Group, based on content published by Zero Networks: “Identity Based Attacks: Tactics, Trends, and Identity Security Best Practices”.
Key questions
Q: What breaks when attackers steal a valid identity credential?
A: A valid credential collapses the difference between an external attacker and a trusted user or workload.
Q: Why do valid credentials make lateral movement so hard to detect?
A: Valid credentials let attackers appear to be normal users or administrators, so the traffic often blends into routine operations.
Q: What are the signs that machine identities are being overprivileged?
A: Common signs include service accounts with broad network reach, unused privileges that remain enabled, credentials with no clear owner, and identities that persist long after the system or project changed.
Practitioner guidance
- Tighten access around valid credentials Treat successful authentication as the start of control, not the end of it.
- Inventory machine identities separately Build a separate governance view for service accounts, API tokens, and other non-human credentials.
- Enforce segmentation at the identity layer Constrain which identities can reach which assets, logon types, and protocols so stolen credentials lose value outside their approved route.
Bottom line: Identity-based attacks succeed when valid credentials are treated as trustworthy by default rather than as a reason to narrow access.

Legacy IAM is being bypassed at the trust boundary, not defeated at the authentication screen. The article shows that valid credentials, session theft, and exposed secrets let attackers appear legitimate to systems that still equate successful login with trustworthy access. That makes identity-based attacks a governance problem, not just an authentication problem. Practitioners should read this as a signal that trust must be enforced after login, not assumed at login.
A question worth separating out:
Q: How should organisations reduce the risk of identity-based attacks?
A: Organisations should combine MFA, rate limiting, password hygiene, and continuous privilege review with strong identity lifecycle controls. The goal is to make stolen credentials less useful and to remove access quickly when it is no longer needed. That approach reduces both initial compromise and the chance that an attacker can expand access after entry.
