Not sure why the topic was locked.  I am not able to respond to the answer that was given and there questions were not really answered, so here goes again. 

 

Hello All,

 

I have a Windows 7 computer that seems to have the newer version,  of telsa crypt. I understand from reading some of the posts, that there is no way of decrypting. There are no added file ext. that one might expect.  Also, What puzzles me is that the files do not seem to be encrypted as I can open them, though I am getting the ransom note that seems to open up in Corel, with a .png ext., pictures seem to open without the note, the only files that seem to bring up the note are Excel files but, when the notes are closed, the files open without issue and the data seen and manipulated.

 

I get an error message when opening up public Documents, My Music, My Pictures, My Videos, stating access is denied. There were 3 files under each one of the headings, RECOVERenchc.html, .png, txt

Nothing was stored in there so it is not a big deal but, it is curious. The user data is primarily in Documents in the user profile.

 

AND, these same three files (over 10,000 when a search on C: is done)  are in many of the folders and subfolders on the C drive. except for, it seems in the user's profile, WIndows, Program files, Program data, Program Files (x86). The public and default profile has these 3 files in many of the sub folders but, not the actual users profile.

 

Also regarding the public documents folders, the permissions seem to be changed to Deny Everyone and System is the owner with special permissions. Special permissions are also assigned to Administrators and Everyone. I am waiting to change anything on the computer though until getting input from you all.

 

User is not an admin on the machine, though when the infection hit, she did say that when prompted for the admin password she typed it in and immediately new she made a mistake. She was in a hurry and wasn't thinking. Wondering if the program did not fully run and there may be a way of determining that and cleaning it up.

 

Word docs don't bring up the ransom note either when opening them. I would have thought that nothing could be opened. A little puzzled by this and wonder what the best way to proceed would be.

 

Let me know what else is needed.

 

Thanks.

 

Joe

 END OF ORIGINAL POST (with a couple revisions...)

 

Could someone please answer the specific questions that were presented?  I am not looking to decrypt or back up.  I am looking for information to determine in fact if the files are actually encrypted.

 

And I would like the oppurtunity to respond, so if you could not lock the post, it would be appreciated.

 

Thanks

Joe

I explained in your other topic that you are most likely dealing with TeslaCrypt ransomware which leaves files (ransom notes) with names like RECOVER+[random].TXT, RECOVER[5-random].TXT, recover_file.txt and _rEcOvEr_[5-random].txt, Recovery+[5-random].txt, _ReCoVeRy_+[5-random].txt, Recovery_[5-random].txt, _H_e_l_p_RECOVER_INSTRUCTIONS+[3-random].txt, _recovery_+cryptolocker.txt, RECOVERY.TXT.

Your RECOVER[5-random].TXT, .HTML and .PNG files are just another ransom note name.

Support for this ransomware is in this topic where you can ask questions and seek further assistance...including letting someone look at some of your files.

Instructions for uploading samples files to SendSpace can be found in Post #1 of this topic. You can then post the link with your samples along with your request for help in the above TeslaCrypt 3.0/4.0 Support & Discussion Topic.

There are hundreds of folks who are infected with ransomware who come here for assistance by our small volunteer staff. It is unmanageable for everyone to have their own individual topic so we send folks to the applicable support topic where help can be provided by those who analyze crypto malware. That is what I explained in your previous topic and the reason it was closed.
