Thank you for this information mate, it would be a big help for every newbie like me to be careful about some activities we are doing online. You really need to be careful especially when you have important data in your device because the virus is always there and hackers are always there as well trying to gain an advantage over you. If you won't be careful and you don't secure very well your device then it will be a big loss for you.
One thing that hooked me is that why they have a fixed ransom which is $300 only for decryption, well in fact they can make it more especially if they get very controversial information on a company, business, and person.
How to protect yourself from a ransomware
1. Suspicious and irrelevant emails should not be opened.
2. Use official and verified download channels
3. Software should be updated with functions/tools provided by legitimate developers.
4. Have a reputable anti-virus/anti-spyware suite installed and kept up-to-date.
We can also don't forget the most important things on how can we avoid this ransomware. Always back up your files so whenever you received ransomware like that, you won't panic because you have the backup.
