Identity attack lifecycle: what IAM teams need to fix now

TL;DR: Identity-based attacks now span compromised credentials, phishing, cloud misconfiguration, privilege escalation, persistence, and exfiltration, with CrowdStrike saying valid account abuse drove 35% of cloud-related incidents and Hydden arguing that blind spots make traditional IAM a paper shield. The core problem is that identity controls are often built around assumed states rather than continuous discovery and context.

NHIMG editorial — based on content published by Hydden: From Account Creation to Data Exfiltration

By the numbers:

• Valid account abuse was responsible for 35% of cloud-related incidents.
• Only 20% have formal processes for offboarding and revoking API keys, and even fewer have procedures for rotating them.
• Only 5.7% of organisations have full visibility into their service accounts.

Questions worth separating out

Q: How should security teams reduce identity-based initial access risk?

A: Security teams should focus on credential exposure, phishing resistance, and detection of abnormal authentication patterns.

Q: Why do service accounts and API keys increase lateral movement risk?

A: Service accounts and API keys increase lateral movement risk when they are over-permissioned, long-lived, or poorly tracked.

Q: What breaks when identity inventories are incomplete?

A: When identity inventories are incomplete, defenders cannot tell which accounts are legitimate, which are dormant, and which are attacker-created.

Practitioner guidance

• Build continuous identity discovery into the control stack Replace periodic audits with always-on discovery across cloud, SaaS, on-prem, and CI/CD so shadow identities and unmanaged credentials are visible before attackers find them.
• Tighten lifecycle controls for service accounts and API keys Track creation, rotation, ownership, and offboarding for every non-human identity, and treat orphaned credentials as active attack paths rather than housekeeping issues.
• Inspect privilege edges between IAM, PAM, and cloud roles Map where one compromised identity can reach another, especially across privileged groups, service principals, and PAM workflows that can widen blast radius.
