My story: My mom calls me up and says her company computer has a virus. Sends me this photo. http://i.imgur.com/k8irmNZ.jpg of ransomware. I had her do a system restore for 1 week prior. Because of the system restore I do not have a ransom letter that was placed on the desktop. 

 

I ran the screen shot through the ID tool and got http://i.imgur.com/Ibbe2yo.png but I am unsure if it didn't work because of a crappy photo.

 

All  files are locked up and when you try to open them it says: The file you are trying to open, 'File name here.xls' is in a different format then specified by the file extension. Verify that the file is not corrupted and is from a trusted source before opening the file. Do you want to open the file now? .jpeg is still a .jpeg but wont open. None of the file names look different just will not open

 

To check corruption I have ran sfc/scannow in Comm Prompt and nothing was found.

To find any clue on the ransomware itself I ran a ton of online scans and one found this.. http://i.imgur.com/71LAPDt.jpg Now, could this mean its CRYPT? The only removal tool i found was CRYPT.XXX and i ran the tool on one file. Nothing was found, nothing was fixed.

 

Does anyone know what this ransomware program is?

Pls assist I have done all I can and need people smarter then me.

 

Edit: I know pictures of screens are bleepty, the first one was sent to me and the scan shot was because I don't want any files off that computer on to mine. Just wanted to redeem myself because I roll my eyes when I see pictures of screens.

First off, ID Ransomware cannot decipher anything from a screenshot; I'm not Google Image search. In your case since you didn't have a ransom note, you'd have to put in one of the URLs or Bitcoin addresses from the screen to get it identified.

 

It's Nemucod-AES. Good news for you is Emsisoft just released a decrypter for it today.

Thoough, I'm worried about the System Restore; you should never do such modifications to a system after a ransomware attack. You need to identify what you are dealing with first. The only way to decrypt this ransomware (even if you paid), is with the .db file, as described in the article.

That is wonderful, Thank you so much!

 

I have the scan running now and thanks to that page we know it came into the system via UPS email. I was thinking worse case I can re download the ransomware to re-infect for its removal. My only worry with going down that road is it will encrypt an encrypted file and ill lose the original file. Can that happen?

 

Is it better to reinfect then scan or try a scan first?

 

EDIT: Never mind the scan worked regardless of the restore I did. I don't know how that didn't mess it up but i am grateful it worked. Thanks again

Never reinfect a system. For most ransomware, the keys are generated per run, and in this case, each file has a different key anyways. You would have just corrupted the files beyond repair.

Glad to hear you were able to decrypt the data. Now please educate your mother about opening phony emails and attachments from unsolicited senders, and set them up with backups backups backups!

Now that the infection has been identified, rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the below support topic discussion.To avoid unnecessary confusion, this topic is closed.

Thanks
