Ransomware is a common term used to describe malicious programs which can encrypt and withhold data from its owner in exchange for “ransom” payment. Did you know that in recent months several healthcare organizations have been a victim of ransomware and have had significant impact to clinical operations?
Ransomware usually prevents or limits a user’s ability to access to their system by disabling the system screen or locking files unless a ransom is paid. Attackers inform the user that they must make a time-sensitive payment (in a virtual currency, typically Bitcoin) to see their files again. Even if users pay the ransom, there is no guarantee that the files will be unlocked or will be uncorrupted
For ransomware, prevention is absolutely the best strategy. You can avoid organizational disruption by following some simple best practices:
| Don’t fall for phishing attempts: An overwhelming majority of ransomware is delivered through phishing emails that contain malicious links and attachments. Never enter your password credentials if asked to by a suspicious email. |
| Be wary of unexpected attachments: Maintain a healthy level of skepticism before clicking on any email attachments. Ransomware can find its way onto your device and make its way into WCH’s servers when a user unsuspectingly downloads an attachment that contains the malware. |
| Avoid delaying your computer’s updates. These updates often include updates to antivirus and antimalware software. |
| Act fast if you suspect infection – If you think your system or device is infected, immediately disconnect from the internet – both wired and wireless. Next, alert the WCH Digital Security Team and/or the Service Desk. |
Reminder: It starts with you! Be sure to participate in the quizzes and phishing simulations that will be taking place throughout the month. Not only will these activities serve as a healthy refresher for cyber security awareness – there are also many fabulous prizes to be won!
