Ransomware – One Wrong Click Can Be Costly
[October 22, 2020] Ransomware is malicious software used by cybercriminals that infects a computer and displays messages demanding the victim pay a fee in order to access their system/files again. They may also threaten to publish his/her data online.
Ransomware is a class of malware that can be installed through deceptive links in an email message, instant message, or website. There are several things the malware might do once it’s taken over a victim’s computer, but the most common consequence is to encrypt some or all of the user's files.
How to Prevent Ransomware
- Pay attention to details to identify tell-tale cues of phishing.
- Hover your cursor over links before clicking to see where they will actually take you or to see what type of file you might be downloading.
- Keep your operating system patched and up-to-date to ensure you have fewer vulnerabilities to exploit.
- Don't install software or give it administrative privileges unless you know exactly what it is and what it does.
- Install antivirus software that detects malicious programs like ransomware as they arrive. Sheridan employees who are running Windows on their workstations have access to CrowdStrike Falcon Antivirus.
- Save or back-up your files regularly to your Sheridan OneDrive. While this won't stop a malware attack, it can make the damage caused by one much less impactful. If your OneDrive files get deleted, overwritten, corrupted, or infected by malware, you can restore your entire OneDrive to a previous time and undo all the actions that occurred on both files and folders within the last 30 days.
