Full breach record for The Children's Hospital of Philadelphia →3 incidents on file

The Children's Hospital of Philadelphia (CHOP) reported to HHS on 2018-10-23 a Hacking/IT Incident affecting 5,368 individuals. On August 23, 2019, a phishing email sent to 679 Outlook users enabled an unauthorized actor to access a physician's email account and the accounts of five employees who forwarded work email externally. The compromised account contained PHI including demographic and clinical information of approximately 5,368 patients. CHOP responded by disabling the account, recalling phishing emails, blocking the phishing site, resetting credentials, notifying affected individuals, and offering credit monitoring. Staff phishing training and a risk assessment update followed. OCR obtained documented assurances of corrective action.
