Microsoft Decryption ransomware is the name of the latest variant in the CryptXXX family. Files get encrypted while retaining their names and extensions. That is clever as it might hindrance the detection of the malware for security software. An asymmetric algorithm for encryption is used based on RSA-4096. The decrypter the criminals have provided does not work, or at least that is what many victims report.
After encryption is complete, the ransomware will give you a personal ID, for you to use in any of the provided websites to pay. To see how to remove the ransomware and what you can try to recover your files, you should read the article carefully.
|This variant of the CryptXXX ransomware is called Microsoft Decryption. All files including ones found on network drives will get encrypted, while preserving their names. The ransom money that is asked doubles if it is not paid within 100 hours.
|The Microsoft Decryption ransomware encrypts files while these files preserve both their file names and extensions. Creates a few README files of different formats and gives links to certain sites, based on the TOR network. It demands payment to grant access to a decryption tool, which does not even work.

Microsoft Decryption Ransomware – How Did I Get Infected?
Microsoft Decryption ransomware is a variant of CryptXXX, and the methods of infection are almost the same as its previous variants. The most effective way of spreading the infection is through an exploit kit. Infecting your computer with an exploit kit happens when you enter a website, which is compromised and will inject a malicious script from the Darkleech malware camapign. The exploit kit which is used this time is Neutrino. The kit might send a shockwave Flash exploit from where to make its entry.
Spam emails might also get you infected with Microsoft Decryption ransomware. The emails have might have malicious files attached, which are hidden from their true form. Social media or file-sharing networks could be spreading the ransomware further. DropBox was one of the platforms used to spread variants of the CryptXXX ransomware virus, in the past. Files can be presented as useful applications, so be careful in what you click and download.
Microsoft Decryption Ransomware – Technical Analysis
The Microsoft Decryption is the improved variant of the CryptXXX 3.0 ransomware.
This new variant encrypts files and demands ransom money as per usual. The newest thing about the ransomware is that uses a simple but in the same time clever trick to make its detection hard. The trick is that files preserve their filenames and their extensions. If left unpaid for 100 hours or around four days the price doubles. If your PC gets infected a registry key can be created, which is tied to this virus:
At a later moment, three files are downloaded through the exploit kit and left on a user’s desktop.
The files are the following:
The .bmp file is put on your desktop as a background image. The .txt file contains the ransom message, and the .html file opens a browser to display the ransom message with enabled html code. That is done so the links to become clickable.
Here you see the full .html file loaded:
The file has links that redirect to payment sites which can redirect you once more after you enter your ID. Again, multiple domains are used, and they are all on the TOR network, so the cyber crooks can hide their location. All files contain the same text inside, which is also shown in the above image:

What happened to your files ?
All of your files were protected by a strong encryption with RSA4096
More information about the encryption keys using RSA4096 can be found here: https://en.wikipedia.org/wiki/RSA_(cryptosystem)
How did this happen ?
!!! Specially for your PC was generated personal RSA4096 Key , both public and private.
!!! ALL YOUR FILES were encrypted with the public key, which has been transferred to your computer via the Internet.
!!! Decrypting of your files is only possible with the help of the private key and decrypt program , which is on our Secret Server
What do I do ?
So , there are two ways you can choose: wait for a _miracle_ and get _your_ PRICE DOUBLED! Or start obtaining *BITCOIN NOW! , and restore _YOUR_ _DATA_ easy way If You have really valuable _DATA_, you better _NOT_ _WASTE_ _YOUR_ _TIME_, because there is _NO_ other way to get your files, except make a _PAYMENT_

After entering your personal ID number, you will enter the platform of the decryption service. There you will see the full payment instructions.
Microsoft Decryption ransomware asks the ransom price of 1.2 BitCoins, which is the equivalent of 788 US dollars, as initial payment. You will have around four days to pay. If you don’t make the payment, the price increases two times (2.4 Bitcoins), but no threats are being made about your files getting lost.
Do NOT pay these cyber criminals. They will keep making new iterations of their ransomware. Not only that, but they keep sticking to the same broken decryption tool, which just gives an error. No reason exists to lose your money on that by supporting the criminals financially.
The Microsoft Decryption ransomware encrypts files with the extensions encrypted by CryptXXX 3.0:
→.3dm, .aes, .ARC, .asc, .asf, .asm, .asp, .avi, .bak, .bat, .bmp, .brd, .cgm, .class, .cmd, .cpp, .crt, .csr, .CSV, .dbf, .dch, .dcu, .dif, .dip, .djv, .djvu, .doc, .DOC, .docb, .docm, .docx, .DOT, .dotm, .dotx, .eml, .fla, .flv, .frm, .gif, .gpg, .hwp, .ibd, .jar, .java, .jpeg, .jpg, .key, .lay, .lay6, .ldf, .max, .mdb, .mdf, .mid, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .ms11, .MYD, .MYI, .NEF, .obj, .odb, .odg, .odp, .ods, .odt, .otg, .otp, .ots, .ott, .PAQ, .pas, .pdf, .pem, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .PPT, .pptm, .pptx, .psd, .qcow2, .rar, .raw, .RTF, .sch, .sldx, .slk, .sql, .SQLITE3, .SQLITEDB, .stc, .std, .sti, .stw, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .bz2, .tbk, .tgz, .tif, .tiff, .txt, .uop, .uot, .vbs, .vdi, .vmdk, .vmx, .vob, .wav, .wks, .wma, .wmv, .xlc, .xlm, .xls, .XLS, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .zip, .zipx
The extension list might be a bit larger now with the latest variant, but the extensions in the above list are still being encrypted. When the encryption process fully completes, all files which are found on your computer and your network will remain with the names and extensions they had before the encryption.
The Microsoft Decryption ransomware uses an asymmetric RSA-4096 algorithm for encryption. That algorithm makes a public encryption key and a private decryption key.
Microsoft Decryption ransomware deletes Shadow Volume Copies from the Shadow Explorer process in the Windows Operating System, just like other variants of the ransomware.
Malware researchers from Kaspersky and TrendMicro have provided decryption tools for previous variants of the ransomware – you should read more about that in the article about Cryp1 (UltraCrypter) ransomware. Continue reading, to see how you can try to recover some of your files.
