Wana Decryptor / WanaCrypt0r

Alright, guys. This is a tough one: However, there's no reason to claim it's impossible to decrypt victims data. These idiots always let something slip through their fingers. Their servers might be found and keys restored to their respective victims. Errors might be found in their code, their key encryption scheme may have some weakness, etc. Let's just let the experts find a way out.

By the way, if you want to temporarily protect your PC from this malware, you may do this.

CryptoDefense: Keys pair stored on disk!

This little detail slipped through their fingers... TOO LATE!

(I actually hid this post when I understood that it might alert the crooks. But SYMANTEC did!)

This is the exact path where your keys are:


Windows XP
C:\Documents and Settings\<USERNAME>\Application Data\Microsoft\Crypto\RSA\S-1-5-2... Windows 7
X:\Users\<USERNAME>\AppData\Roaming\Microsoft\Crypto\RSA\S-1-5-21... (X stands for your hard-disk letter, which is commonly C in most computers)

The private key is encrypted via DPAPI (Data Protection API). There are many RSA keys in that folder though, but you can still find them by sorting these files by date. If you don't remember the date you got infected, see your screenshot at the crook's webpage or search for the oldest HOW_DECRYPT.TXT file in your system.
I'll update this blog soon!


Software Utilities and Assistance

We have been requested many times to provide download links to all the tools we have used (and developed) to reverse the encryption schemes of some ransomware. These tools include Network Sniffers, TCP/IP Traffic Dumpers, Hex Editors, Debuggers and so on.
For those of you who like to get hands down to work, we'll gladly provide you with them. If you are not a computer geek and just need assistance, send us an E-mail and we'll try to fix your problem.
Bear in mind that we get many requests per day, so you must be patient!
Sincerely, the HD team.

You infected the wrong fool!

Yeah, I recovered all my files. ALL and EACH one of them without paying a PENNY. If that wasn't enough, we are also helping victims to recover their files without payment. 

Dear CryptoDefense Authors, if you are reading this: SCREW YOU. Your awful script kiddie skills led our team of true experts to THWART your evil plans, even though you used state-of-the-art RSA encryption. What a bunch of fools! that's like loosing a football match having Lionel Messi, Cristiano Ronaldo and Xavi on your team.

Next step is to report all your domain names (that you lamely use to infect more and more victims).

Now, if you are a victim, feel free to write us at howdecrypt@gmail.com
