Days after hackers held Hollywood Presbyterian’s health information hostage (view related post), the Los Angeles County Health Department was hit with a ransomware attack that reportedly affected five computers. According to the Health Department, the ransomware did not spread or compromise the Department’s network.

No ransom was paid in this case. How did it happen? The usual way—employees opened attachments they received via email and in came the malware.

We are seeing more and more sophisticated phishing and spear phishing attacks and more and more employees being duped by them. This case provides another reason to consider enterprise-wide training of employees so they can detect and prevent a cyber-attack.
