This ransomware struck in October of 2014.  It did not change the extensions of my files, it simply dropped a weblink titled INSTALL_TOR that led to the URL:

https://paytordmbdekmizq.tor4pay.com/z0pN4e

This page is no longer extant.  

 

There may have been a ransom demand file dropped on my desktop that I deleted by mistake, not  yet knowing what had happened. 

 

Would like to know if this is a recognized entity, and if so, what brand of ransomware (I think it's a variant of CryptoLocker?) and has anyone developed a decrypt method for it?  

 

Thanks.

You can submit samples of encrypted files and ransom notes to ID Ransomware for assistance with identification and confirmation.

Samples of any encrypted files, ransom notes or suspicious executables (installer, malicious files, attachments) that you suspect were involved in causing the infection can be submitted here (http://www.bleepingcomputer.com/submit-malware.php?channel=168) with a link to this topic.

Once we have identified which particular ransomware you are dealing with, we can direct you to the appropriate discussion topic for further assistance.

Sorry, forgot to mention that I ran it through ID Ransomware, submitting both the link and a sample corrupted file, and it was unable to identify. 

 

So my next step is...?

You said this infection occurred in 2014. An earlier version of CryptoWall 2.0 left files (ransom notes) named install_tor.url. CryptoWall does not change extensions on a file like many other ransomware infections which encrypts a file and adds an obvious extension to the end of the affected filename.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0, CryptoWall 3.0 & CryptoWall 4.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ.

Unfortunately at this time there is no fix tool and decryption of CryptoWall files...is impossible since there is no way to retrieve the private key that can be used to decrypt your files without paying the ransom. For a more detailed explanation, read this reply by Nathan (DecrypterFixer).

The only methods you have of restoring your files is explained in the FAQ: How to restore files encrypted by CryptoWall...but there is no guarantee that will work. As with most ransomware infections...the best solution for dealing with encrypted data is to restore from backups. If that is not a viable option, the only other alternative is to save your data as is and wait for a possible breakthrough...meaning, what seems like an impossibility at the moment (decryption of your data), there is always hope someday there may be a potential solution so save the encrypted data and wait until that time.

There are ongoing discussions in these topics where you can ask questions and seek further assistance.Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in one of the above support topic discussions. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.

Thanks
