Healthcare
Where a breach can cost lives, not just data.
Healthcare is the most frequently ransomware-targeted sector globally — and the stakes of a breach extend beyond data loss to patient safety. Ransomware that disrupts hospital operations has been directly linked to patient harm. The combination of valuable data, life-critical systems, and chronically underfunded IT makes healthcare a primary target for both organised criminal groups and nation-state actors.
Threat landscape
Ransomware Targeting Clinical Systems
Healthcare-targeted ransomware groups (LockBit, BlackCat/ALPHV, Royal) specifically target hospital networks, knowing that the risk to patient care forces rapid payment. Ransomware has caused documented patient diversions, cancelled surgeries, and delayed emergency care — consequences that extend beyond financial loss.
PHI Exfiltration & HIPAA Exposure
Protected Health Information (PHI) commands premium prices on criminal markets — up to $250 per record, compared to $5 for financial records. Double extortion (encrypt + threaten to publish PHI) is standard practice among ransomware groups targeting healthcare.
Connected Medical Device (IoMT) Attacks
Internet of Medical Things devices — infusion pumps, imaging equipment, ventilators, patient monitors — run on legacy operating systems (Windows XP, Windows 7) that cannot be patched. They create persistent network footholds for lateral movement and can be manipulated to affect patient care.
Legacy System Exploitation
Hospital networks routinely contain systems running unsupported operating systems that cannot be updated without replacing expensive medical equipment. These systems are connected to clinical networks and frequently accessible from the same network segment as modern workstations.
Vendor & Supply Chain Access
Medical equipment vendors, radiology outsourcing partners, and clinical software providers often have standing VPN access to hospital networks. Compromise of a vendor's credentials or network provides direct access to the hospital's clinical infrastructure.
Compliance & regulations
Health Insurance Portability and Accountability Act — Security Rule requires administrative, physical, and technical safeguards for Protected Health Information. Includes provisions for risk analysis and workforce security training.
Digital Personal Data Protection Act — applies to processing of health data as 'sensitive personal data'. Requires consent, purpose limitation, and data minimisation for all health data processing.
Information security management in health — provides healthcare-specific guidance on implementing ISO 27001 controls in clinical environments with medical device considerations.
Widely adopted in healthcare for structuring security programmes. Provides Identify, Protect, Detect, Respond, Recover functions applicable to clinical environments.
National Accreditation Board for Hospitals requires information security standards as part of accreditation criteria for Indian healthcare providers.

03
HIPAA / DPDPA aligned reporting
Our reports are structured to support your HIPAA Security Rule risk analysis requirements and DPDPA data protection obligations — providing the risk evidence your compliance team needs without additional translation work.
Sample engagement
Anonymised case study — Confidential — Multi-hospital group, Southern India
Challenge
Following a near-miss ransomware incident at a peer institution, the hospital group's board mandated a comprehensive ransomware preparedness assessment before their next accreditation review. The IT team had limited visibility into their network segmentation between clinical and administrative systems.
Approach
UnlockSec delivered a combined VAPT and Ransomware Resiliency assessment. The VAPT identified network segmentation gaps between the radiology PACS system and the main hospital network. The ransomware simulation tested backup resilience and conducted an IR tabletop with the CISO, IT Director, and clinical informatics lead.
Outcome
Critical finding: PACS system had direct network access to clinical workstations with no segmentation — allowing potential ransomware propagation to clinical endpoints. 2 backup resilience gaps identified: daily backups without offline copies, and recovery time objective significantly longer than assumed. All critical findings remediated before the accreditation review.
