The biggest healthcare data breach in July and in all of 2018 was a phishing attack on Iowa Health System dba UnityPoint Health. The threat actor spoofed the email account of an executive and sent email messages to UnityPoint Health employees. Some employees were tricked into disclosing their login details, which allowed the attacker to access their email accounts. The PHI of over 1.4 million patients were contained in those email accounts.
