Ransomware

What is Ransomware?

Ransomware is a type of malicious software designed to block access to a computer system until a sum of money is paid. These incidents, often involving sensitive or personal information, can result in financial loss and an erosion of trust.

There has been an increase in incidents of malicious cyber actors using ransomware to access data.

SPECIAL TIP: Check your software applications for the most recent versions. Outdated apps and operating systems are the target of most ransomware attacks. If your apps need to be updated, you’ll probably be prompted to update them. Go ahead. If there’s an option to automatically update in the future, select that option. Because some apps don’t have auto-updating features, it’s best to check them all. 

Avoid becoming a victim

Be careful as you use the internet.

• Be wary of unfamiliar websites.
• Examine URLs carefully.
• Ensure attachments are genuine and from an expected source.
• Don't click on suspicious links.

The Cybersecurity & Infrastructure Agency recommends:

• Know what personal and sensitive information is stored on your systems and who has access to it.
• Limit the data by only storing information you need for business operations.
• Ensure data is properly disposed of when no longer needed.
