Long story short, I had a computer running one of the ransomware programs that encrypts files.  This computer was on the network and encrypted a few folders that contain office files, PDF and photo's.  I ran combofix and malwarebytes on the infected computer before I realized it was a ransomeware virus.  How can I determine which of the ransomeware programs has encrypted my files.  None of the files have different extensions, there are no txt files in the directories to give me a clue as to which program has encrypted my files.  Does anyone know how I can determine which virus has encrypted my files?

As I mentioned in the original post, I had a computer that was infected with ransonware.  I did not konw it at the time as the user was complaining about performance issues and abnormal behavior on her computer.  I ran combofix and malewarebytes on her computer to check for malware and it cleaned some things off her computer.  The next morning is when we discovered that ransomeware had infected the documents on the server that she was mapped to and the documents on her computer.  I searched and reviewed her hard drive, but I never could find any specific evidence of what type of ransomware was on her computer.  There were no ransom notes and none of the file extensions were changed.  I have recovered most of the files from backup or other sources, but there are some that my client really wants to recover and I am trying to see if there is a way for me to identify what ransomware had encrypted my files and is there a way to decrypt them.

Hello lonestar2500 and welcome to BleepingComputer!           :)

 

My name is Sirawit and I'm here to help you.

 

Please note that I'm currently in training and my fixes need to be approved first, that may delay our fix a bit, but I will normally reply back in 24 hours.

 

If I don't reply after 3 days, feel free to PM me.            :)

==========================================================================

Some points for you to keep in mind:

  • Backup any files that cannot be replaced. Removing malware can be unpredictable and this step can save a lot of heartaches if things don't go as planned. You can put them on a CD/DVD, external drive or a pen drive, anywhere except on the computer.
  • We ask you to run different tools in a specific order to ensure the malware is completely removed from your machine, and running any additional tools may detect false positives, interfere with our tools, or cause unforeseen damage or system instability.
  • Please do not run any tools or take any steps other than those I will provide for you while we work on your computer together. I need to be certain about the state of your computer in order to provide appropriate and effective steps for you to take. Most often "well intentioned" (and usually panic driven!) independent efforts can make things much worse for both of us. If at any point you would prefer to take your own steps please let me know, I will not be offended. I would be happy to focus on the many others who are waiting in line for assistance.
  • Do not attach logs or use code boxes, just copy and paste the text.
  • Periodically update me on the condition of your computer, and provide detail in every post.
  • In the upper right hand corner of the topic you will see the Followtopic.jpg button. Click on this then choose Immediate E-Mail notification and then Proceed and you will be sent an email once I have posted a response.
  • If you do not reply to your topic after 5 days we assume it has been abandoned and I will close it.
  • Once things seem to be working again, please do not abandon the thread. I will give an "all-clean" message at the very end with some additional information on how to stay malware-free.
  • Lastly, I would like to remind you that most members here are volunteers, and sometimes "real life" can get in the way of our malware hunt. I will notify you if I know I will need to be away for longer than 48 hours.

==========================================================================

 

I've submitted my reports to my instructor and will reply to you as soon as possible.

 

Thank you.


If I don't reply back to you in 2 days, feel free to send me a PM.

Hi lonestar2500.

 

Please run IDTool so we can know which ransomware variant you got.

 

IDToolbyNathan.png Scan with IDTool

 

Please download IDTool by Nathan and save the file to the desktop.
It will come as a zipped file, so you will need to unzip it. You may do it by right-clicking on it and choosing Extract All. Extract it to your desktop.

  • Enter the IDTool directory, right-click on IDToolbyNathan.png icon and select RunAsAdmin.jpg Run as Administrator to start the tool.
  • IDTool needs Microsoft .NET Framework environment to work properly, so if prompted to download & install it please agree.
  • Please patiently wait for the tool to collect necessary data. 
  • Once the main console is loaded, please press Rescan Computer and Generate a New Report.
  • When prompted at the main bar that Rescan is completed, press Generate Text Friendly Report for Forums.
  • Copy the entire content of the frame that appears. You may want to save it to a text file for your convenience.

Please include that in your next reply.

 

--------------

 

Please download Farbar Recovery Scan Tool and save it to your Desktop.

Note: You need to run the version compatible with your system. If you are not sure which version applies to your system, download both of them and try to run them. Only one of them will run on your system, that will be the right version.

  • Right-click FRST then click "Run as administrator" (XP users: click run after receipt of Windows Security Warning - Open File).
  • When the tool opens, click Yes to disclaimer. 
  • Press the Scan button.
  • When finished, it will produce a log called FRST.txt in the same directory the tool was run from.
  • Please copy and paste the log in your next reply.

Note 2: The first time the tool is run it generates another log (Addition.txt - also located in the same directory the tool was run from). Please also paste that, along with the FRST.txt into your next reply.

 

Thank you.


If I don't reply back to you in 2 days, feel free to send me a PM.
