Decoder@tutamail.com ransomware is a particularly unpleasant type of malicious software (not that any types of malware are anything to relish being infected by...) But unlike some of the malware programs which will show you adverts or redirect your internet searches – adware and Potentially Unwanted Programs we’re looking at you - ransomware is a program that can cause you real distress, delete or damage your personal files – and even wind up costing you a fair amount of money. Here's an example of how an encrypted Word file is listed in a folder:
As you can see, the original file name is tasks-aug.docx. The encoder virus encrypted it and added a unique id, in this case 5874213680, and an email address firstname.lastname@example.org that should be used to contact cyber criminals and receive further steps on how to get your files back. They also mentioned email@example.com in a ransom note in case the main one doesn't work or you don't receive a response within 48 hours. What is more, it's not longer and .docx file but an executable file. This ransomware changes file extension for who knows what reasons because when a file is encrypted the extension isn't important.
Sounds nasty – just what is this ransomware?
It has been designed with one aim in mind: to make money. Not only that but it does so by preying on our fears and vulnerabilities. As the name suggests, ransomware infects your PC then holds your files, photos, documents, etc, etc, hostage. It normally encrypts them so you have no chance of breaking the code and accessing them while it is on your machine. It then demands that you pay a ransom in return for the decryption code that will release your files. However one thing to bear in mind if you do get hit by ransomware is that there are numerous tales of people parting with their cash only to receive no code whatsoever. And it's not like you are going to be able to call a ransomware programmer's helpline to ask for assistance, is it? Although, you can email them.
Other ways ransomware gets you to pay a fine
As well as holding your documents to ransom, firstname.lastname@example.org ransomware can also change your default browser settings so that accessing the internet is virtually impossible. Of course, this is unacceptable as the vast majority of us need the web to be able to do our jobs and, increasingly, live our lives. How long do you think you'd last without the internet on your computer? Would you crack and simply pay the ransom?
How to get my files back?
If you have a recent backup, wipe your hard disk and reinstall your files. If you don't, try Shadow Explorer program or search your computer for previous versions of files. If you are lucky enough you may find files that were not encrypted. But before restoring your files, please remove the ransomware and related malware files from your computer.
