WannaCry Malware Prompts Call for Vigilance

In wake of the recent WannaCry ransom-malware attack that has infected more than 200,000 computers worldwide, Enterprise Information Services (EIS) is urging employees to be vigilant when using email.

EIS has issued the following tips to prevent an attack:

  • Be on guard while reviewing emails that originate from outside of Cedars-Sinai (subject now marked with the tag [External]).
  • Forward suspicious emails to spamcheck@cshs.org, then delete.
  • Do not click on attachments or web links in any email whose sender you do not recognize.

Distinct from other malware, ransomware is a type of malicious software that prevents access to a computer system by encrypting it with a key known only to the hacker. After the system data is encrypted, the ransomware directs the user to pay a ransom to the hacker for the decryption key.

WannaCry ransomware-malware started spreading in mid-May and crippled computer networks around the globe. In the United Kingdom, some hospitals had to turn away patients as the malware shut down computer systems.

While Cedars-Sinai deploys sophisticated cybersecurity defenses, attacks remain especially dangerous.

For questions on cybersecurity concerns, email Chris Joerg, chief information security officer, at chris.joerg@CSHS.org, email information.security@cshs.org, or call the EIS Service Desk at 310-423-6428.
