‘WannaCrypt’ Ransomware: Protect Yourself
[May 15, 2017] Many of you may have heard the news about an ongoing worldwide ransomware known as “WannaCrypt”. Ransomware is malicious software which infects a computer, denies access to the system or data, and demands a sum of money to restore the information.
The system vulnerability exploited by “WannaCrypt” was addressed by Microsoft in a security patch that was released in March, and you should know that Microsoft Windows patches are applied automatically to end-user computers managed by Sheridan. However, if your computer is not managed by Sheridan, or you are concerned about a personal device, please make sure your Microsoft security patches are up to date. It is important to ensure that you always apply the latest security and software patches.
Ransomware and other forms of malware are ever evolving. Here are a few additional reminders on how best to protect ourselves at work and at home:
- One of the most important protections against ransomware is making sure to back up your data. Sheridan employees have access to network drives that are backed up every night, making them ideal for storing your most important data:
- Personal Network Drive: Each Sheridan employee is automatically assigned a personal network drive and is allocated 300 MB of disk space. Although 300 MB may be insufficient to store all of your files, it’s a good idea to back-up your most important files.
- Network Shared Drives: A shared network drive is a remotely accessible folder that can be used for storing and sharing files with other users. Many departments already have shared drives set up for their employees.
- Spam emails may contain malware attachments, or links to websites hosting malware. Do NOT click on links or open attachments in e-mails sent to you by someone you do not know. Sheridan will NEVER send you an email asking you to divulge account details, or with links asking you to log into your account. When in doubt, contact firstname.lastname@example.org for a second opinion.
Questions or Concerns?
If you believe your Sheridan computer is infected by ransomware or other malware, contact the IT Service Desk immediately by phoning ext. 2150.
