Challenge 01
PHI Sprawl Across HL7/FHIR Integration APIs
Patient records flowed between EHR, LIS, RIS, and billing through 60+ HL7 v2 and FHIR R4 endpoints with inconsistent auth, exposing PHI to broken object-level authorization and replay risks.

Scope
ERP modules, patient portal, and HL7/FHIR integration APIs to LIS, RIS, and billing systems
The Challenge
What the team was up against
Challenge 02
Dual-Jurisdiction Compliance Pressure
Hospital customers in India demanded DPDP-aligned consent and breach notification while UAE clients enforced ADHICS and HIPAA business-associate obligations, forcing one platform to satisfy three overlapping regulatory regimes simultaneously.
Challenge 03
Multi-Tenant Role Matrix With Clinician Overrides
Doctors, nurses, pharmacists, and billing staff shared a tenant-scoped RBAC model with break-glass overrides for emergencies, creating high risk of horizontal privilege escalation and PHI leakage across hospital tenants.
Our Approach
How we solved it
Step 01
Threat-Modeled Grey-Box Web and API Pentest
Ran STRIDE workshops on EHR, OPD, and pharmacy modules, then executed grey-box testing using Burp Suite Pro, Postman, and custom FHIR fuzzers against OWASP ASVS L2 and OWASP API Top 10 with HIPAA technical safeguard mapping.
Step 02
Authorization Matrix and BOLA Deep-Dive
Built a 40-role authorization matrix across four tenant archetypes, then chained IDOR, mass-assignment, and break-glass abuse cases to validate horizontal and vertical isolation across patient charts, prescriptions, and lab orders.
Step 03
DPDP and HIPAA Gap Assessment With Remediation Sprint
Mapped findings to HIPAA Security Rule 164.312, DPDP Section 8 obligations, and ISO 27001 Annex A.8 controls, then ran weekly fix-verify sprints with engineering until every High and Critical was closed and retested.
The Results
What changed after the engagement
63
Vulnerabilities Surfaced Across Surfaces
Including 9 Critical PHI-exposure issues in FHIR endpoints, 14 High broken authorization flaws, and several mass-assignment bugs in the billing module.
100%
Critical and High Findings Remediated and Retested
Every Critical and High finding was patched by engineering and independently verified by Certbar through targeted retests before the CERT-In certificate was issued.
0
Reportable PHI Incidents in 18 Months Post-Engagement
Across 40+ hospital deployments in India and UAE, no DPDP or HIPAA reportable PHI breach has been recorded since remediation closed.
