What exactly is ransomware?
It’s a malicious computer virus that threatens to destroy your files or online reputation if you don’t pay the large fines set out by the criminals that create them. There is no guarantee that once you pay the fines your files will be returned and you may likely be targeted again.
The RAA ransomware virus
RAA is a new strain of ransomware that’s recently been discovered by security researchers. It’s disguised as a document attached to an email that once opened automatically starts encrypting files.
What are the consequences?
If a user does open the RAA ransomware file it will automatically encrypt all files and display a Russian ransom note on screen along with a set cost to restore all files. The only way to retrieve your files is to use a system backup or pay the fine to the hackers and keep your fingers crossed that you get your files back.
Here’s some useful tips to help protect your company from RAA ransomware attacks
- We advise that awareness of the new RAA ransomware is made public within companies so employees are aware of it and are wary of opening attachments especially with a .js extension.
- Ensure all company Antivirus software is active and kept up to date
- Windows can be programmed not to start the “Windows Based Script Host” when a .js file is double-clicked. We recommend this is implemented on all Windows machines.
- We also advise that macro enabled documents (such as .docm and .xlsm) are proceeded with great caution.
