Ransomware is malicious software that can lock users out of devices or encrypt files, preventing access until a ransom is demanded.

For businesses, an attack can disrupt operations, affect access to important information, and create significant financial challenges.

Ransomware attacks may begin with a phishing email, malicious attachment, unsafe website, or compromised account.

Warning Signs to Watch For

• Files suddenly become inaccessible or have unfamiliar extensions.

• Applications begin freezing or performing unusually slowly.

• Unexpected activity appears on shared drives or cloud storage.

• A device displays a ransom note or message demanding payment.

These signs don't automatically mean ransomware is present, but they should be taken seriously.

How Can You Reduce the Risk?

1. Be cautious with messages. Avoid clicking suspicious links or opening unexpected attachments.

2. Keep security tools enabled. Follow your organization's requirements for antivirus, endpoint protection, firewalls, and software updates.

3. Use strong, unique passwords and MFA. These safeguards can help reduce the risk of unauthorized account access.

4. Follow company security procedures. Use approved applications and secure access tools when handling business information.

What If You Suspect an Attack?

Act quickly.

• Stop interacting with suspicious messages, files, or ransom demands.

• Immediately notify your IT or designated security contact.

• Follow instructions for isolating the affected device or responding to the incident.

• Record what you observed and when, if you can do so safely and without delaying reporting.

Don't attempt to investigate, repair, or recover affected systems on your own. Don't make ransom-payment decisions independently.
