Incident Report
| Target Organization | Concord Eye Center |
|---|---|
| Threat Group | interlock |
| Summary | A private ophthalmology clinic specializing in various fields. However, it completely fails to ensure the security of itself and its clients and is extremely lax in its recordkeeping. The structure of its confidential records is determined by the categories of protected health information (PHI) it creates and stores. Because Concord Eye Center makes no attempt to regulate security, we provide you with the following information: patient identification and administrative data: this includes names, addresses, dates of birth, social security numbers, and contact information; clinical and medical history: detailed symptom records, ophthalmological and systemic medical history, and family history; diagnostic and lab results; surgical and treatment documentation; billing and financial information: insurance information, claims data, and payment records. Leaking these documents would primarily violate the HIPAA Privacy and Security Rules (45 CFR Parts 160 and 164) and the HITECH Act, which provide for tiered civil penalties for each category of violation, leading to distrust of their business by customers and partners and its collapse. |
