Ransomware is a type of malicious software (malware) that freezes your computer or mobile device until a sum of money is paid. It can destroy personal and business files, leading to stolen data and large financial losses.

$209 million collected by criminals in the first quarter of 2016.
A projected $1 billion + in losses from ransomware attacks in 2016 alone, according to the FBI.

Identify
Ransomware targets a specific individual with a business, or a consumer with a link or attachment that infects our computer with malware or leads you to an infected website. Three ways ransomware can take shape are:
Spear phishing emails
The sender appears to be someone you may know or someone relevant to your business.
The message is often personalized, and may include your name or a reference to a recent transaction.
Advertisements or pop-up windows
Your computer freezes, and a popup message appears.
The message may threaten a loss of your files or information, or may also tell you that your files have been encrypted.
Downloadable software
Ransomware is also present in downloadable games and file-sharing applications.
Once the PC is infected, your files are encrypted and inaccessible. The fraudster demands a ransom payment in order to unlock them.
Prevent
Always back up your files and save them offline or in the cloud.
Always use antivirus software and a firewall. Be sure they are set up to update automatically.
Enable popup blockers.
Don't click. Be cautious when opening emails or attachments you don't recognize---even if the message comes from someone in your contact list.
Only download software from sites you know and trust.
Alert your local law enforcement agency as soon as you encounter a potential attack.
