Implement an effective data backup and disaster recovery plan. Q5: What can I do to prevent an attack? What can healthcare organizations do? Here is an example of Locky, a very successful exploit used for ransomware.

Spear-phishing, a variant of a phishing email attack, is more targeted and might include specifics that make an email seem more genuine such as a reference to a company picnic or other data a hacker might find on social media sites. With ransomware, the email or website injects malicious code onto the user's computer with infected hyperlinks.

The first high-profile attack happened in February at Hollywood Presbyterian Hospital. In one recent attack, Medstar Health in Maryland had to turn away patients because the attack crippled their ability to operate.
