Healthcare Cybersecurity Risks in India — The Threat Landscape

Ransomware Targeting Hospital Information Systems

Hospital Information Systems (HIS) — the software platforms managing patient registration,
clinical workflows, billing, and medical records — are the highest-value targets in hospital
IT environments. A successful ransomware attack on the HIS can halt patient admissions,
disable prescription systems, and force doctors to operate on paper in an emergency.

Indian hospitals are particularly vulnerable because many run HIS software on aging Windows
infrastructure, with infrequent patching due to concerns about disrupting clinical operations.
The same unpatched vulnerability that existed for two years becomes the ransomware entry
point that shuts the hospital down.

PACS Vulnerabilities — Imaging System Exposure

Picture Archiving and Communication Systems (PACS) store medical imaging data — X-rays,
CT scans, MRIs, ultrasounds. PACS systems are frequently internet-accessible (for remote
radiologist reading) and run on outdated software. Security researchers have documented
thousands of Indian PACS systems exposing patient imaging data publicly on the internet
without authentication. Compromised PACS systems can also serve as a lateral movement
pivot point into the broader hospital network.

Electronic Medical Record (EMR) Data Breaches

EMR systems contain the complete medical history of patients — diagnoses, medications,
surgical histories, test results, and in many cases biometric and Aadhaar-linked data.
This data has high value on dark web markets (medical identity theft, insurance fraud)
and creates enormous liability under India’s DPDP Act 2023. EMR breaches also raise
serious patient safety concerns where medical history manipulation could affect treatment.

Legacy Medical Device Vulnerabilities

Modern hospitals network a wide range of clinical devices — infusion pumps, patient monitors,
ventilators, imaging equipment, and laboratory analyzers. Many of these devices run embedded
operating systems (often Windows XP or Windows CE) that cannot be patched and connect to
the hospital network for data export and remote maintenance. Compromised medical devices
can be used as network entry points or, in severe scenarios, affect patient care directly.

Telemedicine Platform Security

The rapid expansion of telemedicine post-COVID created a large new attack surface in Indian
healthcare. Telemedicine platforms handle video consultations, e-prescriptions, and patient
registration data, often with security implemented as an afterthought. Application
vulnerabilities in telemedicine platforms can expose patient data, prescription records,
and financial payment information.

Insider Threats in Healthcare

Healthcare organizations have large staff populations with varying levels of system access
— doctors, nurses, ward clerks, billing staff, lab technicians. Unauthorized access to
patient records by staff — whether out of curiosity, malice, or for financial gain
(selling patient data) — is a persistent threat that technical controls, access reviews,
and awareness training must address together.

DPDP Act 2023 & Healthcare — Patient Data Protection Obligations

India’s Digital Personal Data Protection Act 2023 creates significant new obligations for
healthcare organizations. Health data is treated as sensitive personal data under the Act,
and the consequences of non-compliance are substantial.

Who Is Covered

The DPDP Act applies to any organization that processes personal data of Indian citizens
digitally. In healthcare, this includes: public and private hospitals, nursing homes and
clinics, diagnostic laboratories and imaging centers, telemedicine and health app platforms,
pharmaceutical companies with patient data, health insurance companies, and healthcare
IT vendors.

Key DPDP Act Obligations for Healthcare Organizations

• Lawful purpose and consent: Patient data must be collected only for
  specific, legitimate medical purposes. Patients must be informed of how their data is
  used and must provide consent for non-treatment uses (research, marketing).
• Data minimization: Only the minimum necessary patient data should be
  collected and retained. Diagnostic labs cannot retain imaging data beyond clinically
  necessary periods without patient consent.
• Security safeguards: Data fiduciaries must implement reasonable security
  safeguards to prevent data breaches. “Reasonable safeguards” for a large hospital chain
  will be interpreted as significantly higher than for a single-doctor clinic.
• Breach notification: Data breaches affecting patient personal data must
  be reported to the Data Protection Board of India within the prescribed timeline (expected
  to be 72 hours). The definition of “breach” is broad.
• Data subject rights: Patients have the right to access their data,
  correct inaccuracies, and request erasure of data no longer needed for treatment.
  Healthcare organizations must have processes to respond to these requests.
• Data Protection Officer: Significant Data Fiduciaries — large hospital
  chains, national diagnostic companies, major health platforms — will be required to appoint
  a Data Protection Officer and conduct Data Protection Impact Assessments for high-risk
  processing activities.

MDIT’s DPDP Act Compliance Service for Healthcare

MDIT provides a structured DPDP Act compliance program for healthcare organizations:
personal data inventory and data flow mapping, consent management framework review,
privacy notice development, breach notification procedure design, staff training on
patient data rights, and DPO advisory support. The program is designed to integrate with
clinical operational workflows, not disrupt them.

ABDM Security Requirements — Ayushman Bharat Digital Mission

The Ayushman Bharat Digital Mission is India’s national digital health infrastructure,
creating interoperable electronic health records through Ayushman Bharat Health Accounts
(ABHA). Healthcare providers and health IT companies participating in ABDM must meet
specific security and data management requirements.

ABDM Health Data Management Policy

The National Health Authority’s Health Data Management Policy establishes the privacy and
security framework for ABDM. Key security requirements for participating organizations include:

• Data encryption: All health data transmitted over ABDM infrastructure
  must be encrypted using approved standards. Data at rest in participating systems must
  also be encrypted.
• Consent architecture: Health information exchanges within ABDM must be
  preceded by explicit patient consent through the ABHA consent manager. Systems must implement
  the consent framework correctly and maintain consent audit trails.
• Access controls: Only authorized healthcare providers with verified ABDM
  registration can access patient health records. Role-based access controls must restrict
  access to the minimum necessary for clinical functions.
• Audit logging: All access to patient health records through ABDM must be
  logged and auditable. Logs must be maintained for a specified retention period and be
  available to patients on request.
• Security assessment: Health IT systems integrating with ABDM infrastructure
  should undergo security assessment to ensure they meet ABDM security standards before
  production integration.

MDIT’s ABDM Security Service

MDIT provides security assessment and compliance advisory for healthcare organizations
integrating with ABDM — including hospitals implementing ABHA-linked EMR, health IT
companies developing ABDM-compliant HIS, and telemedicine platforms building ABDM
consent workflows. We ensure integrations are secure before they go live.
