I paid the ransom but then my personal home page just disapeared. Is anyone in contact with them or is there a way for me to contact them?

 

My personal page was: htps://paytordmbdekmizq.com/11zjwxg.

 

If someone is in contract could they contact them and say I won't pay since "11zjwxg" paid and did not recieve the key to unencrypt.

 

I really think it was a mistate on their part as I did everything they asked.  Help!

2 things could have happened.

-The malware could have been poorly made which leads to a non existant page where your 'key' was stored by them.

-Or they chose to just be the scumbags that they are and just take the money and said fu. After all, they are criminals.

Im not quite sure if there is anything you can do. Sorry man. Hopefully somebody will have a better answer than me.

Actually as a test they allowed me to pick a file at random on my computer and they unencrypted it immediately. That made me believe they could do what they said.

Hi there,

 

I'm really really sorry for you. I had to pay also (more than a month ago), but for me, the moment i copy-pasted the bitcoin transaction id i got the decrypt.zip file... However it was a crappy decrypter (many .bak - database files backup from an application) were corrupted,  the pictures showed strange horizontal lines (like a 95% complete decryption with errors). Of course, i decrypted only on copies, i still have the original HDD with the encrypted files, i just installed a new windows on a new one. So i wrote on that silly support page and i complained at them that the decrypt doesn't work as it should. After about a week i downloaded again the decrypt.zip file and the CRC was different, this time it worked.

 

Try and try again to go into your page (i've tried but didn't connect) and see if you can download your decrypter archive. If you can work only on copies, make (maybe with norton ghost) some clones of your hard drive, write files on cd,s dvd.s (i mean the encrypted files you need), and work on them on a computer with another hard disk in where you don't risk anything. If you don't have another hard disk, try the decrypter (the antivirus shows is infected) on a computer with deep freeze installed, so after restard you can be sure you have no viruses...

 

Finally... pray ! Pray that the page will get back and you'll get your decrypter back.

 

Another very very slowly solution (and probably the only one for this virus) is to work on virtual machines, get purposely infected and get the decryption page. You can upload there any file encrypted with any key (that decryption test page) and it will decrypt (they probably check the encryption key on a server database, but it works). However,.... you need to have just files lower than 512 KB.

 

Any other solution you'll find at the time i'm writing this is NOT working ! Recovering files is impossible, since they're secure deleted with crazy rewritings on hard disk. the most you might achieve is to get infected again, and that's a nightmare, i know...

 

I'll be praying for you.

Mihai.

I just recovered a clients files today that was encrypted with the Cryptowall 2.0 virus. It got past their anti virus and none of their backups were any good. I paid the $500 ransom after jumping thru hoops to create a bitcoin account and pay extra to have same day fulfillment of my deopsit. I followed the instructions on the virus pop up page and within about 3 hours I was able to download the decrypt.zip file with the public & private keys. It took several hours to decrypt over 10,000 files but looks like they are all there. This is the nastiest virus out there as it erases shodow copies and not only encrypts the local pc files but any files that the pc is mapped to. If you only have a few files it may not be worth it but in this case it was 20 years of contracts and financial files that would have put them out of business had they not been recovered.

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

Reading that Guide will help you understand what CryptoWall & CryptoWall 2.0 does and provide information for how to deal with it and possibly decrypt/recover your files. Cryptowall typically deletes all Shadow Volume Copies with vssadmin.exe so that you cannot restore your files form the Shadow Volumes. At this time there is no fix tool for CryptoWall.

CryptoWall 2.0 uses its own TOR gateways...see Updated CryptoWall 2.0 ransomware released that makes it harder to recover files.

There is also a lengthy ongoing discussion in this topic: CryptoWall - new variant of CryptoDefense.

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 that topic discussion.

Thanks
