Ransomware attacks are on the rise! Here is what you need to know.
What is Ransomware?
Ransomware is a type of malicious software used by cybercriminals designed to block access to a computer system until a sum of money is paid.
How does it work?
Ransomware will lock or encrypt files so the user can no longer access them or even go beyond, rendering the device useless.
The effects of ransomware:
Ransomware can affect both individuals and organisations. It can cause severe damage to not only your systems but your reputation and can cost your business money.
What to look for:
Like other viruses, you need to be wary of:
- Visiting unsafe or suspicious websites
- Opening emails or files from unknown sources
- Clicking on malicious links in email or on social media.
Signs your device might be compromised:
- Pop-up messages are requesting funds or payment to unlock files.
- You cannot access your devices, or your login doesn’t work for unknown reasons.
- Files request a password or a code to open or access them.
- Files have moved or are not in their usual folders or locations.
- Files have unusual file extensions, or their names or icons have changed to something strange.
What to do if you become a victim of ransomware:
The ASCS recommendations are:
- Do NOT pay the ransom (this may leave you vulnerable to future attacks).
- Restore your files from backup and seek advice.
