How to remove Vvmm ransomware, Decrypt .vvmm files.

What is Vvmm virus?

Vvmm virus is a ransomware. Ransomware is a type of malicious software (malware) that encrypts a victim’s files, making them inaccessible. The attackers then demand a ransom payment from the victim, usually in the form of cryptocurrency, in exchange for the decryption key to restore access to the encrypted files. Ransomware attacks can cause significant financial and operational losses, as well as damage to a victim’s reputation if sensitive information is compromised

Vvmm encrypts files, renames them by appending the .vvmm extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “document.docx” will be renamed to “document.docx.vvmm”, a “image.jpg” file to “image.jpg.vvmm”, “invoice.pdf” to “invoice.pdf.vvmm”, and so on.

Vvmm ransomware is a variant of the STOP (Djvu) ransomware. It is spread by websites offering to download freeware, key generators, Windows/Office activators, hacked software, torrents and so on. Upon execution, Vvmm creates a folder in the Windows system directory where it places a copy of itself and changes some Windows settings so that it starts up every time the computer is restarted or turned on. The virus collects information about the victim’s computer and then tries to establish a connection with its command server (C&C). If the connection has been established, then it sends information about the infected computer to the server, and in response receives the encryption key (the so-called ‘online key’) and additional commands and malware that must be executed on the victim’s computer. If the virus could not establish a connection with its command server, then it uses a fixed key (the so-called ‘offline key’).

The Vvmm ransomware encrypts files using a strong encryption algorithm and a key (‘offline key’ or ‘online key’, as described above). The virus tries to encrypt as many files as possible, for this it only encrypts the first 154kb of the contents of each file and thus significantly speeds up the encryption process. Vvmm has the ability to encrypt files on all drives connected to the computer: internal hard drives, flash USB disks, network storage, and so on. It skips without encryption: files located in the Windows system directories, files with the extension .ini, .bat, .dll, .lnk, .sys and files with the name ‘_readme.txt’. The remaining files located on the victim’s computer can be encrypted. For example, the following file types may be the target of ransomware attack:

.1st, .sum, .dazip, .mlx, .ltx, .re4, .3dm, .x3f, .bc7, .xlsx, .3ds, .indd, .dwg, .xwp, .db0, .z, .p7c, .layout, .qic, .wp6, .vpp_pc, .ff, .kdb, .bsa, .sis, .rwl, .syncdb, .sie, .srw, .svg, .dbf, .bc6, .7z, .bik, .mdf, .zabw, .hvpl, .nrw, .wma, .mpqge, .rofl, .apk, .xls, .das, .wot, .sidn, .slm, .t13, .arch00, .mcmeta, .xld, .xpm, .epk, .sav, .sb, .wps, .itm, .wbm, .psk, .wbmp, .snx, .itl, .pptx, .wmv, .map, .zip, .ibank, .xar, .xlsm, .t12, .lvl, .vpk, .zdc, .wav, .wpd, .py, .lbf, .hkdb, .wps, .hplg, .jpg, .wbk, .odt, .psd, .ztmp, .mov, .xls, .wdb, .xy3, .bar, .wmd, .ysp, .yml, .desc, .dba, .wp7, .mp4, .mef, .ppt, .sr2, .wsd, .x, .fos, .litemod, .xml, .xlsm, .cer, .wpb, .sidd, .mdbackup, .fpk, .der, .m2, .wbz, .2bp, .iwd, .crw, .p7b, .pfx, .raf, .docm, .rim, .bay, .ai, .kdc, .orf, .sid, .kf, .jpe, .odb, .p12, .zi, .cfr, .esm, .rar, .wm, .itdb, .vtf, .txt, .png, .cdr, .wgz, .avi, .icxs, .m4a, .wsc, .xlk, .flv, .tor, .pkpass, .xdl, .ntl, .fsh, .rtf, .pem, .vcf, .csv, .xyw, .wpd, .0, .wpt, .pst, .w3x, .wn, .odm, .wp, .gho, .3fr, .xbplate, .wpg, .hkx, .wdp, .xbdoc, .wotreplay, .dcr, .forge, .wp4, .wma, .vdf, .pak, .rb, .cr2, .wire, .wpa, .odp, .dng, .x3d, .vfs0, .tax, .lrf, .ncf, .zw, .asset, .xdb, .xlgc, .iwi, .wbd, .ptx, .odc, .wri, .xll, .xmmap, .yal, .erf, .m3u, .accdb, .pef, .1, .webdoc, .x3f, .jpeg, .crt, .wcf, .qdf, .wpw, .ods, .cas, .dmp, .ybk, .docx, .ws, .bkf, .wbc, .pptm, .xyp, .mddata, .pdf, .xlsb, .y, .d3dbsp, .zip, .wmf, .mdb, .rgss3a, .bkp, .sql

Vvmm encrypts file-by-file. Each file that has been encrypted will be renamed, the .vvmm extension will be added at the end of its name. Thus, it marks all encrypted files. In every directory where there is at least one encrypted file, the virus places a file named ‘_readme.txt’. The file contains a message from the Vvmm authors. An example of the contents of this file is given below.

This message says that all files on the computer are encrypted and the only way to decrypt them is to buy a key and a decryptor from the authors of the Vvmm ransomware. That is, criminals demand a ransom for unlocking the victim’s files. The size of the ransom is $980, but if the victim is ready to pay the ransom within 72 hours, then its size is halved to $490. Attackers offer victims to verify that encrypted files can be decrypted. To do this, the victim must send them a small file to one of the email addresses specified in the ‘_readme.txt’ file. Of course, it is obvious that a single decrypted file cannot guarantee that after paying the ransom, the criminals will provide the victim with a working key and decryptor.

The full text of the Vvmm ransom note is

How to remove Vvmm ransomware

You need to remove the Vvmm ransomware virus (its associated files and Windows registry entries) before proceeding to decrypt or restore encrypted files. This must be done since otherwise the ransomware may re-encrypt the restored files. You can stop the ransomware from working, as it is not difficult to do. Another option is to perform a full system scan using free malware removal tools capable of detecting and removing ransomware infection.

It is very important to scan the computer for malware, as security researchers found that spyware could be installed on the infected computer along with the Vvmm ransomware. Spyware is a very dangerous security threat as it is designed to steal the user’s personal information such as passwords, logins, contact details, etc. If you have any difficulty removing the Vvmm virus, then let us know in the comments, we will try to help you.

To remove Vvmm ransomware, follow the steps below:

How to decrypt .vvmm files

As we already reported above, files with .vvmm extension are files that have been encrypted by the Vvmm ransomware. Their contents will remain locked until decrypted using the decryptor and the key. Fortunately, there is a free Vvmm File Decrypt Tool that can decrypt .vvmm files. Below we provide instructions on where to download and how to use this decryptor.

To decrypt .vvmm files, use Vvmm File Decrypt Tool

• Download Vvmm File Decrypt Tool from the following link.
  STOP Djvu decryptor
• Scroll down to ‘New Djvu ransomware’ section.
• Click the download link and save the decrypt_STOPDjvu.exe file to your desktop.
• Run decrypt_STOPDjvu.exe, read the license terms and instructions.
• On the ‘Decryptor’ tab, using the ‘Add a folder’ button, add the directory or disk where the encrypted files are located.
• Click the ‘Decrypt’ button.

Vvmm File Decypt Tool is a free software that can decrypt files that were encrypted with an offline key, as Emsisoft found a way to determine this key. Unfortunately, files encrypted with an online key cannot yet be decrypted. The online key is unique to each infected computer, and at the moment there is no way to obtain this key. Of course, criminals have this key, but we do not think that paying a ransom is a way to decrypt .vvmm files. In the case when the files are encrypted with an online key, there is a chance to restore the encrypted files using alternative methods, which are described below.

How to find out which key was used to encrypt files

Below we will demonstrate how to find out the type of key with which files were encrypted. This is very important, since knowing the type of key you can understand if you can decrypt .vvmm files for free using the Vvmm File Decypt Tool. We recommend using the second method, as it is more accurate.

How to find out the type of a key using ‘_readme.txt’ file

• Open the ransom demand message (‘_readme.txt’ file).
• Scroll down to the end of the file.
• There you will see a line with the text ‘Your personal ID’.
• Below is a line of characters, this is your personal id.

How to find out the type of a key using ‘PersonalID.txt’ file

• Open disk C.
• Open directory ‘SystemID’.
• Open file named ‘PersonalID.txt’. This file lists ‘Personal ID’s that match the keys that the virus used to encrypt files.

The ‘Personal ID’ is not a key, it is an identifier related to a key that was used to encrypt files. If the ID ends with ‘t1’, then the files are encrypted with an offline key. If the ID does not end with ‘t1’, Vvmm virus used an online key. If you could not figure out how to determine which key was used to encrypt files, then we can help. Just write a request here or in the comments below.

Vvmm File Decrypt Tool : “No key for New Variant online ID”

If, when you try to decrypt .vvmm files, Vvmm File Decrypt Tool reports:

No key for New Variant online ID: *
Notice: this ID appears to be an online ID, decryption is impossible

It means that your files are encrypted with an ‘online key’ and their decryption is impossible, since only the Vvmm authors have the key necessary for decryption. In this case, you need to use alternative methods listed below to restore the contents of encrypted files.

Vvmm File Decrypt Tool : “No key for New Variant offline ID”

If, during decryption of .vvmm files, Vvmm File Decrypt Tool reports:

No key for New Variant offline ID: *t1
Notice: this ID appears be an offline ID, decryption MAY be possible in the future.

It means the following: your files are encrypted with an ‘offline key’, but the key itself has not yet been obtained by security researchers, in this case, you need to be patient and wait a while, in addition, you can also use alternative ways for recovering encrypted data.

If for some reason you were unable to decrypt the encrypted files, then We recommend to follow the news on our Facebook or YouTube channels. So you ‘ll know right away that it ‘s possible to decrypt .vvmm files.

This video step-by-step guide will demonstrate How to use STOP Djvu decryptor to Decrypt encrypted files.

How to restore .vvmm files

As we mentioned above, in addition to using the Vvmm File Decypt Tool, there are several more methods for recovering encrypted files. These methods do not require the use of a decryptor and a key, and therefore are suitable for all cases when the ransomware used an online key, and for the case when the ransomware used an offline key. It is very important to check your computer for malware before you try to recover encrypted files. You must be 100% sure that Vvmm virus is completely removed. To scan your computer for ransomware, use free malware removal tools.

Recover .vvmm files with ShadowExplorer

The Microsoft Windows has a feature called ‘Shadow Volume Copies’ that can help you to recover .vvmm files encrypted by the ransomware. A small tool called ShadowExplorer will allow you to easily access the Shadow copies and restore the encrypted files to their original state. Unfortunately, the ransomware can delete these Shadow copies before it starts encrypting files. Therefore, if ShadowExplorer did not help you, then try another method, which is given below.

ShadowExplorer can be downloaded from the following link. Save it on your Microsoft Windows desktop.

After the download is done, open a directory in which you saved it. Right click to ShadowExplorer-0.9-portable and select Extract all. Follow the prompts. Next please open the ShadowExplorerPortable folder as on the image below.

Start the ShadowExplorer tool and then choose the disk (1) and the date (2) that you want to restore the shadow copy of file(s) encrypted by the Vvmm ransomware virus as displayed below.

Now navigate to the file or folder that you wish to recover. When ready right-click on it and press ‘Export’ button like below.

This video step-by-step guide will demonstrate How to recover encrypted files using Shadow Explorer.

Use PhotoRec to restore .vvmm files

The last chance to restore encrypted files to their original state is using data recovery tools. We recommend a program called PhotoRec. It has all the necessary functions to restore the contents of encrypted files. It helped many victims recover data when it seemed like there was no more hope.

Download PhotoRec by clicking on the link below. Save it on your Windows desktop.

When the download is complete, open a directory in which you saved it. Right click to testdisk-7.0.win and choose Extract all. Follow the prompts. Next please open the testdisk-7.0 folder like the one below.

Double click on qphotorec_win to run PhotoRec for Windows. It will open a screen as displayed in the following example.

Choose a drive to recover as displayed on the screen below.

You will see a list of available partitions. Choose a partition that holds encrypted documents, photos and music as displayed on the screen below.

Click File Formats button and select file types to recover. You can to enable or disable the recovery of certain file types. When this is done, click OK button.

Next, click Browse button to choose where restored photos, documents and music should be written, then click Search. We strongly recommend that you save the recovered files to an external drive.

Count of restored files is updated in real time. All recovered files are written in a folder that you have selected on the previous step. You can to access the files even if the restore process is not finished.

When the restore is complete, click on Quit button. Next, open the directory where recovered photos, documents and music are stored. You will see a contents as on the image below.

All recovered photos, documents and music are written in recup_dir.1, recup_dir.2 … sub-directories. If you are searching for a specific file, then you can to sort your restored files by extension and/or date/time.

This video step-by-step guide will demonstrate How to recover encrypted files using PhotoRec.
