Remove CrypMIC Ransomware Virus and Restore Encrypted Files

STF-crypmic-cryptxxx-ransomware-copycat-ransom-note

The ransomware CryptXXX was such a huge success for cyber criminals that others made a copycat version of it. The copycat is called CrypMIC, and it utilizes the same distribution method, while also using the same ransom note and payment sites. The biggest difference between them is that CrypMIC does not encrypt files with a specific extension and uses another encryption algorithm.

This may actually be the same version of Microsoft Decryptor ransomware or another version imitating it. However, there is plenty more information about the virus in this article.

To see how to remove the ransomware virus and what you could apply to recover your files, you should read the article carefully.

CrypMIC Ransomware – Distribution

CrypMIC ransomware uses an exploit kit for its distribution. The ransomware uses the Neutrino exploit kit as its entry point – same as CryptXXX. Other exploit kits could be used for distribution in the future – with malware campaigns from compromised sites or hijacked sub-domains. For now Neutrino is one of the most effective exploit kits and TrendMicro labs reported that it spreads the following ransomware families as well:

TeslaCrypt was also being delivered by Neutrino earlier this year, but as its authors released the master decryption key, and thus the attention has shifted to CryptXXX.

The CrypMIC ransomware has its payload stored in a .DLL file with a random name. Beware that this makes it easy to spread and besides the exploit kit, spam emails, social media and file sharing networks might be used as a delivery way as well. Be very careful in opening files, links and emails of unknown origin or that seem suspicious.

CrypMIC Ransomware – Technical Description

The CrypMIC ransomware is a copycat of CryptXXX. However, it has quite a few differences. For instance, it does not apply a persistence mechanism such as an auto-start feature. Another interesting thing is that it does not feature a lockscreen. However, it does employ a check routine for the presence of any Virtual Machines being run and sends that data over its C&C (Command and Control) server.

CrypMIC encrypts files with a strong algorithm, but does not put any extension to the encrypted files. After encryption is complete the following files are created:

  • README.TXT
  • README.HTML
  • README.BMP

The files are almost 100% the same as those of CryptXXX, as names and content, and serve the same purpose. The .html file is made just after the file encryption is finished. The file launches a browser to display the .html code. This makes the links inside clickable. This file makes copies of itself in directories with encrypted files. The file also has a .TXT and a .BMP version. The latter of the two is a picture which is set as a desktop background, but the screen does not get locked.

You can see the .BMP file right here:

We removed the hyperlinks from the image for safety purposes but know that they lead to the same payment sites for decryption as the CryptXXX virus. The links may differ per infected users, but will lead to those domains hosted by the original ransomware owners.

The file displayed above reads the following:

NOT YOUR LANGUAGE? USE https://translate.google.com

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: http://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

CrypMIC ransomware asks the price of 1.2 BitCoins, to be paid as ransom. That is nearly 800 US dollars, which is very high as an initial payment. You will be given a period of 4 days to make the payment. If you don’t pay in that time frame, the price doubles and becomes 2.4 Bitcoins. No threats are made that your files can get lost after time.

Do NOT pay these criminals. CrypMIC ransomware is a copycat so you don’t know what will happen with your money if you do. Paying the ransomware is not a good option because the decrypter might not work as in the original ransomware variant.

The ransomware locks over 900 different file types. Some of the files that CrypMIC ransomware seeks to encrypt have these extensions:

→.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 encryption algorithm used here is AES 256-Bit, although the ransom note states it is RSA-4096. After the process, the virus sends information about the current state of the system and the result of encryption to its C&C server. It uses the TCP protocol on the 443 port. Over the C&C the ransomware can also do a check if a VM (Virtual Machine) is running and send that data back.

CrypMIC ransomware deletes Shadow Volume Copies with the Vssadmin in Windows.

CrypMIC FAQ

What is CrypMIC ransomware and how does it work?

CrypMIC is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files.

Many ransomware viruses use sophisticated encryption algorithm how to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

How does CrypMIC ransomware infect my computer?

Via several ways.CrypMIC Ransomware infects computers by being sent via phishing e-mails, containing virus attachment.

This attachment is usually masked as an important document, like an invoice, bank document or even a plane ticket and it looks very convincing to users.

After you download and execute this attachment, a drive-by download occurs and your computer is infected with the ransomware virus.

Decryptor did not decrypt my data. What now?

Do not panic and backup the files. If a decryptor did not decrypt your .CrypMIC files successfully, then do not despair, because this virus is still new.

One way to restore files, encrypted by CrypMIC ransomware is to use a decryptor for it. But since it's a new virus, advised that the decryption keys for it may not be out yet and available to the public. We will update this article and keep you posted as soon as this decryptor is released.

How Do I restore ".CrypMIC" files (Other Methods)?
