TL;DR: API abuse now hides inside valid tokens, normal sessions, and low request volumes, so rate limits and signatures miss the real attack surface, according to AccuKnox. The control problem is not traffic volume but runtime intent, because behaviour, identity, and flow context determine whether an API session is legitimate or abusive.

Questions worth separating out
Q: What breaks when API abuse controls rely only on rate limits?
A: Rate limits fail when abuse stays within normal volume but violates intent, sequence, or entitlement.
Q: Why do service accounts make API abuse harder to detect?
A: Service accounts often look like trusted automation, so their traffic can blend into normal operational patterns.
Q: How do security teams know if API behaviour is outside its intended boundary?
A: Look for repeated sequence violations, unusual response-byte accumulation, and calls that succeed while breaking expected business flows.
Practitioner guidance
- Implement per-identity behaviour baselines Define normal API session patterns for users, service accounts, and application tokens, then alert on deviations in sequence, cadence, and rolling-window volume.
- Continuously discover shadow and zombie APIs Build runtime inventory from observed traffic, gateway telemetry, and service mesh traces so inactive-looking endpoints and forgotten paths are still governed.
- Correlate identity and flow telemetry Join IdP events, gateway logs, and workload traces so investigators can see the full chain from authentication to action.

AccuKnox's full article covers the operational detail this post intentionally leaves for the source:
- Runtime control examples for Kubernetes ingress, service mesh, and workload-level enforcement points
- Specific policy actions for bot credential stuffing, scraping, business logic abuse, and low-and-slow exfiltration
- Telemetry combinations that pair gateway logs, IdP events, and eBPF signals for investigation

API abuse is an identity problem before it is a traffic problem. When valid tokens, service accounts, and delegated sessions can carry abusive flows, the control failure sits in identity context, not packet inspection. That is why IAM, PAM, and API security teams need a shared view of session legitimacy, not separate control planes. The practical conclusion is simple: govern API access as a runtime identity surface, not just as an application interface.
A question worth separating out:
Q: Who is accountable when an exposed API credential is abused?
A: Accountability should sit with the service owner and the identity governance function, not just the platform team. API credentials are lifecycle assets, so control failure usually spans design, issuance, monitoring, and retirement. Frameworks like the NIST Cybersecurity Framework 2.0 help structure that ownership.
