What’s even worse is that ransomware attacks are on track to rise by 250% by the end of 2016.
What is ransomware?
Malicious software that is designed to block access to files or your whole computer, until a sum of money is paid.
Most common types of ransomware:
Crypto ransomware– targets specific data on your device (usually office, PDF and image files), as well as the file system.
Locker ransomware– targets the entire device, preventing you from logging in to your PC or device.
How can my devices become infected by ransomware?
Email attachments– unknowingly clicking files attached in emails that contain ransomware.
Compromised websites– visiting websites that have become compromised and download malware to your computer.
Installing Infected software– software (usually freeware) can have ransomware built in.
How does ransomware work?
- A user either receives or downloads malware to their device
- Ransomware then infects your device
- The malicious code connects back to the hacker’s server which then encrypts files on your device
- A ransom note is issued demanding payment for decryption of your device (or a threat of full wipe).
How can I protect my business against ransomware?
Education– education is essential to protect your business against ransomware. It is critical that your staff understands what ransomware is and the threats it poses. We recommend providing your staff with examples of suspicious emails with clear instructions on what to do if they encounter a potential ransomware email (i.e. don’t open/click attachments and report suspicious emails).
Security– having effective and up-to-date security tools such as antivirus, anti-malware, popup blockers are crucial.
Offsite backup– ensure you have a regular offsite backup of data that can be recovered in case of an attack
