How to remove Vveo ransomware, Decrypt .vveo files.

What is Vveo virus?

Vveo virus is a ransomware that belongs to the ransomware family called STOP (Djvu). Ransomware is a form of malware that encrypts the victim’s files and demands a ransom for decrypting them. The Vveo virus encrypts files, renames them by appending the .vveo extension, and creates files named “_readme.txt” containing the ransom demand message. For example, a file named “image.jpg” will be renamed to “image.jpg.vveo”, a “document.docx” file to “document.docx.vveo”, “invoice.pdf” to “invoice.pdf.vveo”, and so on.

Vveo ransomware in detail

Vveo ransomware is a malware that encrypts files on the victim’s computer and demands a ransom payment to restore access to the contents of these files. Vveo targets users running Microsoft Windows. In most cases, this malware requires user actions in order to be installed on the computer. Typically, criminals use various tricks, for example, disguising the malicious software as a freeware, cracks, activators and key generators, so that victims download and run Vveo virus on their computer.

Upon infecting a computer, it performs the following steps as part of its preparation for encrypting files: creates a folder in the Windows system directory and copies itself to it; adds itself to the list of programs that start up every time the computer is turned on; collects information about the victim’s computer; establishes connection with its command server (C&C).

If the Vveo virus was able to establish a connection with the command server, then it sends some information about the victim’s computer to the server, and the server returns a key to it that must be used to encrypt files. Such a key is called ‘online key’ and it is unique for each case of ransomware infection. If a connection to the command server has not been established, Vveo uses a fixed key (so called ‘offline key’), which is unique for each version of STOP (djvu) ransomware, but the same for each case of Vveo infection.

Having determined which key to use, the Vveo ransomware virus goes to the main thing – it starts the file encryption process. Of course, it does not encrypt absolutely all files, since encryption of the Windows system files will cause the computer to stop working. Therefore, the ransomware does not encrypt files located in the system directory of Windows, as well as files with the following extensions: ‘.sys, .dll, .lnk, .ini, .bat’. In addition, Vveo virus does not encrypt files named ‘_readme.txt’. All other files will become the target of the malware, for example, the following file types can be encrypted:

.wdp, .bay, .crt, .zi, .wpt, .wotreplay, .cfr, .pem, .sid, .yml, .odp, .wbz, .ltx, .mrwref, .lvl, .ppt, .mcmeta, .z, .wdb, .wp, .asset, .wma, .mdbackup, .blob, .sis, .upk, .rw2, .docx, .xdb, .tax, .wpd, .wav, .mlx, .dmp, .xls, .iwd, .sb, .xbdoc, .xyw, .zip, .menu, .wbc, .odt, .wma, .pef, .zip, .bc6, .dba, .py, .3fr, .mov, .vtf, .7z, .qdf, .wot, .mdf, .xmind, .pptm, .hplg, .xpm, .wpl, .hkx, .xll, .zw, .kf, .ntl, .dwg, .rwl, .map, .xlgc, .mef, .wbm, .raf, .arw, .slm, .xxx, .arch00, .litemod, .t13, .fpk, .bar, .vfs0, .xx, .psd, .p12, .itl, .wm, .zif, .xlsx, .xlk, .lrf, .cr2, .rgss3a, .pkpass, .flv, .avi, .xwp, .mddata, .rtf, .pak, .pdd, .ztmp, .xls, .wcf, .jpg, .png, .bkf, .wire, .cas, .nrw, .erf, .xlsm, .xlsb, .wps, .dazip, .w3x, .kdc, .vpk, .odc, .wpg, .pptx, .dxg, .fsh, .tor, .pfx, .wmv, .r3d, .webdoc, .yal, .sql, .bkp, .ncf, .forge, .raw, .rar, .dng, .rim, .hkdb, .xdl, .p7c, .sie, .xlsm, .mp4, .d3dbsp, .0, .itm, .das, .bc7, .pst, .wri, .icxs, .wsc, .wps, .sr2, .der, .wb2, .wbk, .jpeg, .xbplate, .mpqge, .srw, .sidn, .vcf, .indd, .m2, .wp7, .kdb, .gdb, .wpb, .db0, .desc, .bik, .wbmp, .vpp_pc, .hvpl, .srf, .t12, .wmf, .1st, .xlsx, .jpe, .xyp, .xld, .3dm, .wn, .wp5, .ptx, .m4a, .wmv, .accdb, .syncdb, .crw, .iwi, .wp4, .js, .apk, .sum, .3ds, .xy3, .cer, .txt, .dbf, .big, .wmd, .orf, .odb, .wmo, .x3f, .xmmap, .1, .wgz, .itdb, .rb, .webp, .p7b, .zdb, .snx, .ibank, .esm, .css, .doc, .x3d, .wpd, .wsd, .cdr, .xml, .docm, .qic, .wpa, .zdc, .m3u

All encrypted files become completely useless, their contents cannot be read in any way. To clearly show that the files are encrypted, the ransomware virus appends a new ‘.vveo’ extension at the end of the filename of each encrypted file. This means the following: if the file had the name ‘photo-image.jpg’, then after it has been encrypted, it will be called ‘photo-image.jpg.vveo’. In all directories where there are encrypted files, the Vveo virus drops a file named ‘_readme.txt’

This file contains text written by the Vveo authors. In this message, the criminals report that the user’s files were encrypted and the only way to get them back is to purchase a key and a decryptor. Attackers give the victim 72 hours. At this time, the key will cost $490, after 72 hours the ransom will increase to $980. The message also contains the contact information of the criminals, using which the victim can check the ability of the attackers to decrypt .vveo files, as well as find out where to send the ransom.

The full text of the Vveo ransomnote:

In file ‘_readme.txt’, criminals scare victims by saying that encrypted files cannot be decrypted without paying a ransom. And unfortunately this is true, the contents of the files cannot be read while the files are encrypted, and a key and decryptor are needed to decrypt them. Fortunately, there is a free Vveo File Decrypt Tool. This decryptor can help each victim to decrypt .vveo files for free. But in addition to this decryptor, the key is still necessary. As we reported above, the virus can use two types of keys. An offline key can be determined by security researchers, but only criminals have an online key. Thus, files encrypted with so called ‘offline key’ can be decrypted. And all files that have been encrypted with so called ‘online key’ cannot yet be decrypted. In this case, the alternative methods listed below in this article can be used to recover the contents of these files.

How to remove Vveo virus (ransomware)

Before you start decrypting or recovering .vveo files, you need to remove the Vveo virus. 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 read the entire instruction manual carefully and make sure to understand it all. We advise you not to skip any steps, each of the steps is very important and must be completed by you. In order not to get confused and not miss an important point in the instructions, we recommend that you print this article or open it on your smartphone.

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 Vveo 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 Vveo virus, then let us know in the comments, we will try to help you.

To remove Vveo virus, follow the steps below:

1. Kill Vveo virus
2. Disable Vveo startup
3. Delete Vveo task
4. Remove Vveo virus

Kill Vveo virus

Press CTRL, ALT, DEL keys together.

Click Task Manager. Select the “Processes” tab, look for something suspicious that is the Vveo virus then right-click it and select “End Task” or “End Process” option. If your Task Manager does not open or the Windows reports “Task manager has been disabled by your administrator”, then follow the guide: How to Fix Task manager has been disabled by your administrator.

It is not difficult to detect a process related to the Vveo ransomware. When looking for a malicious process, pay attention to the process icon and its name. Most often, this ransomware has a process name in the following format: 4-characters.tmp.exe or 4-characters.exe. For example: 7533.tmp.exe, A4b1.exe, CD15.tmp.exe, 19b2.exe. The process name can also contain “(32 bit)”. If you do not find a process with a similar name in the list of processes, then most likely the Vveo ransomware has finished working. But keep in mind, if you do not remove the ransomware autostart entries, as demonstrated below, and do not delete its file, then after a while it may start again, and if it finds unencrypted files, immediately encrypt them.

Disable Vveo startup

Select the “Start-Up” tab, look for something similar to the one shown in the example below, right click to it and select Disable.

Close Task Manager.

Delete Vveo task

How to decrypt .vveo files

Files with the extension ‘.vveo’ are encrypted files. The ransomware uses a long key and a strong encryption algorithm, so it is impossible to decrypt files without a key and decryptor. Criminals demand a ransom for the key and the decryptor. Of course, even paying a ransom, there is no guarantee that victims will receive the required key and decryptor. Fortunately, a team of experts from Emsisoft created a decryptor that helps everyone to decrypt the encrypted files for free.

To decrypt .vveo files, use Vveo File Decrypt tool:

• Go to the following link to download Vveo File Decrypt tool.
  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.

Vveo File Decrypt Tool is a free software that can decrypt the encrypted files only in some cases, when the files were encrypted with an ‘offline key’. If the files were encrypted with an ‘online key’, then they cannot be decrypted. The reason for this is that the decryption key is in the hands of criminals and this key can not be determined. This does not mean that if your files are encrypted with an online key, then their contents are lost forever. Fortunately, there are several ways to recover encrypted files. These methods do not involve the use of decryption and therefore can be used in any case, no matter what key the ransomware used to encrypt files.

How to find out which key was used to encrypt files

Since Vveo File Decrypt Tool only decrypts files encrypted with an offline key, each Vveo’s victim needs to find out which key was used to encrypt the files. Determining the type of key used is not difficult. Below we give two ways. Use any of them.

Find out the type of 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.

Find out the type of 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’, Vveo 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.

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

If, when you try to decrypt .vveo files, Vveo 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 Vveo 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.

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

If, during decryption of .vveo files, Vveo 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 .vveo files.

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

How to restore .vveo files

If the Vveo File Decrypt tool cannot decrypt the encrypted files or your data is encrypted with an online key, then there is no need to despair. Fortunately, there are several alternative methods that can allow everyone to recover the contents of encrypted files. Each of these methods does not involve the use of special knowledge and paid programs and can be performed by everyone. We have prepared an instruction with illustrations, which describes in detail the process of data recovery. Before you begin data recovery, if you have not completed step 1, then go back. You must be 100% sure that the Vveo ransomware virus is completely removed. We recommend using free malware removal tools.

Run ShadowExplorer to recover .vveo files

The first and very simple way to restore encrypted files to the state in which they were before encryption is to restore files from their Shadow Copies. The Shadow Volume Copies are copies of files and folders that Windows automatically saved as part of system protection. This feature is fantastic at rescuing personal files that were locked by the Vveo ransomware. The guide below will give you all the details.

Installing the ShadowExplorer is simple. First you will need to download ShadowExplorer on your Microsoft Windows Desktop from the link below.

When downloading 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 such as the one below.

Launch the ShadowExplorer tool and then select the disk (1) and the date (2) that you wish to restore the shadow copy of file(s) encrypted by the Vveo ransomware as on the image below.

Now navigate to the file or folder that you wish to recover. When ready right-click on it and press ‘Export’ button as shown in the following example.

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

Use PhotoRec to restore .vveo files

Another way to recover encrypted files is to use data recovery programs. There are many such programs, but most of them are paid. We recommend using a program called PhotoRec. It has all the necessary functions and is completely free.

Download PhotoRec from the link below. Save it directly to your Windows Desktop.

When downloading 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 as displayed in the following example.

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

Choose a drive to recover as shown on the image below.

You will see a list of available partitions. Choose a partition that holds encrypted files as shown in the figure below.

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

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

Count of recovered files is updated in real time. All recovered documents, photos and music are written in a folder that you have chosen on the previous step. You can to access the files even if the recovery process is not finished.

When the recovery is done, click on Quit button. Next, open the directory where restored files are stored. You will see a contents like below.

All recovered files are written in recup_dir.1, recup_dir.2 … sub-directories. If you’re 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.
