Ransomware is a growing concern. This malicious cyber threat locks down a system or encrypts the files requiring a ransom to be paid to regain access. Data rich organizations, like hospitals and universities are prime targets. Typically ransoms are low enough to make paying a more attractive solution than fighting. However, the FBI does not recommend paying ransom because it encourages cyber thieves. Ransom payment is in done in bitcoin, a digital currency that is unregulated and untraceable. Beware: sometimes criminals do not provide the decryption key after receiving payment.
Become more cyber savvy. Learn these ransomware facts:
- Often delivered by phishing emails with malicious attachments or spoofed links, or dodgy websites.
- Targets organizations of all types and sizes plus individuals as well.
- Shared files, like Google Drive, Dropbox and other shared drives, are at risk. If someone accidentally clicks on a phishing email or a bad link ransomware can lock out all users.
What to do if confronted with ransomware:
- Stop all activity on your computer
- Disconnect your computer from intranet, internet or WiFi
- Immediately contact your designated IT staff for assistance
How to protect yourself:
- Regularly back-up all personal files - documents, pictures, etc.
- Install good antivirus, firewall and antimalware on personal computers, smartphones & tablets.
- Keep all software up to date by turning on auto updates
- Use secure websites when doing transactions (check for the "S" in https)
- Scrutinize emails - don't click on "phishy" links or unusual attachments
- Don't use public WiFi for any transactions (email, shopping, etc.)
