Remove TeslaCrypt and Restore .vvv Encrypted Files

A new variant of the nefarious TeslaCrypt ransomware is circling the Web. This time, the malicious threat is encrypting files in a .vvv file format. Once it affects your system, it will create thousands of files inside multiple folders, along with “how_recover+abc” files to which a ransom note is attached.

TeslaCrypt Ransomware – How Did I Get It?

We have already seen other members of this ransomware family around the Web. Learn more about TeslaCrypt and AlphaCrypt.

Ransomware such as TeslaCrypt could enter your system in a number of ways.

The most common distribution method known is through malicious email attachments and spam emails. There are even cases, where the email body itself contains a malicious code and upon opening the email, the user infects his computer with it, even if he doesn’t open the attachment inside.

Social networks and file sharing services may also contain the TeslaCrypt ransomware, disguised as a regular file. Keep in mind that TeslaCrypt may hide in dubious websites as well. Once you visit such a website, you risk infecting your system with TeslaCrypt without you even knowing it.

TeslaCrypt Ransomware – Description

Once executed, the latest TeslaCrypt ransomware will search for files with more than 150 extensions, and more specifically the following ones:

→.sql, .mp4, .7z, .rar, .m4a, .wma, .avi, .wmv, .csv, .d3dbsp, .zip, .sie, .sum, .ibank, .t13, .t12, .qdf, .gdb, .tax, .pkpass, .bc6, .bc7, .bkp, .qic, .bkf, .sidn, .sidd, .mddata, .itl, .itdb, .icxs, .hvpl, .hplg, .hkdb, .mdbackup, .syncdb, .gho, .cas, .svg, .map, .wmo, .itm, .sb, .fos, .mov, .vdf, .ztmp, .sis, .sid, .ncf, .menu, .layout, .dmp, .blob, .esm, .vcf, .vtf, .dazip, .fpk, .mlx, .kf, .iwd, .vpk, .tor, .psk, .rim, .w3x, .fsh, .ntl, .arch00, .lvl, .snx, .cfr, .ff, .vpp_pc, .lrf, .m2, .mcmeta, .vfs0, .mpqge, .kdb, .db0, .dba, .rofl, .hkx, .bar, .upk, .das, .iwi, .litemod, .asset, .forge, .ltx, .bsa, .apk, .re4, .sav, .lbf, .slm, .bik, .epk, .rgss3a, .pak, .big, wallet, .wotreplay, .xxx, .desc, .py, .m3u, .flv, .js, .css, .rb, .png, .jpeg, .txt, .p7c, .p7b, .p12, .pfx, .pem, .crt, .cer, .der, .x3f, .srw, .pef, .ptx, .r3d, .rw2, .rwl, .raw, .raf, .orf, .nrw, .mrwref, .mef, .erf, .kdc, .dcr, .cr2, .crw, .bay, .sr2, .srf, .arw, .3fr, .dng, .jpe, .jpg, .cdr, .indd, .ai, .eps, .pdf, .pdd, .psd, .dbf, .mdf, .wb2, .rtf, .wpd, .dxg, .xf, .dwg, .pst, .accdb, .mdb, .pptm, .pptx, .ppt, .xlk, .xlsb, .xlsm, .xlsx, .xls, .wps, .docm, .docx, .doc, .odb, .odc, .odm, .odp, .ods, .odt

After TeslaCrypt threat finds files with these extensions, it will encrypt them with the extension “.vvv”. This variant does not use data files like the previous one, nor does it store information about the decryption key on the compromised computer.

So, decryption is possible, by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets. If you have a sniffer set before the attack happened you might get information about the decryption key. Another way to get your files back is to restore them if you have backups on an external storage device. Other potential ways for decryption are included in the instructions at the end of the article.

In the ransom note it is described how you can pay the ransom with different currencies like, BitCoins, Ukash, and PayPal My Cash Cards. At the end of the note, there is an upload form, where you can test if the decryption will work:

teslacrypt-8-variant-.vvv-extension-decryption-page-ransom-note-decrypt-how-recover-test-file-support

We advise you not to pay the ransom, as there is no guarantee you will get a decryption key, let alone a working one. The ransomware can create thousands of files with the names: decrypt.exe, decrypt.html, and decrypt.txt, along with the ransom note files, how_recover+abc.txt and how_recover+abc.html.

4.Restore Files Encrypted by TeslaCrypt

Security engineers strongly advise users NOT to pay the ransom money and attempt restoring the files using other methods. Here are several suggestions:

To restore your data, your first bet is to check again for shadow copies in Windows using this software:

Shadow Explorer

If this method does not work, Kaspersky have provided a decryptors for files encrypted with the this and other encryption algorithms:

Kaspersky Decryptors

Another method of restoring your files is by trying to bring back your files via data recovery software. Here are some examples of data recovery programs:

There is also the technical option to use a network sniffer:

Another way to decrypt the files is by using a Network Sniffer to get the encryption key, while files are encrypted on your system. A Network Sniffer is a program and/or device monitoring data traveling over a network, such as its internet traffic and internet packets.

    Hello,

    To all users who have had their files ENCRYPTED.

    The newest variant of TeslaCrypt is not yet analyzed so there may be very little chance to decrypt your files.

    But you can still try with the following decryption tools, mentioned in our forum:

    Please, let the others know if it worked so that you can raise awareness.

        Hello Omar,

        If I understand correctly, you can see folders in your previous versions. Before doing anything else, you should remove TeslaCrypt with an anti-malware tool. Let me know how it goes. Also, it would help if you send me an email to idunn0@abv.bg with 3 or 4 encrypted files and some files of the virus (.tmp, .bin, .exe or .dll).

        Thanks in advance and looking forward to your reply.

    Hello Eric and Steph, an antivirus program should remove the leftovers of the ransomware. However, it won’t be able to decrypt the encrypted files. Please keep in mind that every infection is unique, and that there are may be more variants of the same ransomware.

      Hey Luke!

      TeslaCrypt is a Trojan horse ransomware. This means that it is a Trojan itself, and it was spread with other malware.

      There were executables that dropped with the ransomware in these locations:

      %Temp%
      %AppData%
      %LocalAppData%
      %ProgramData%
      %WinDir%
      or randomly in the C: drive.

      But no data for the key was dropped for this variant, neither was the Windows Registry tampered by it.

      Fortunately, this ransomware case has already been resolved : http://sensorstechforum.com/teslacrypt-master-decryption-key-available/

      Stay tuned!

    You can use the shadow copy of your windows to recover the previous version before the attack. This is the best safest way. You can have other tool like ShadowExplorer-0.9-portable that will help to recover your previous good version.

    Nach über 10 Jahren habe ich es wiede mal geschafft meinen PC zu infizieren. Ärgerlich das dies nur durch meine unvorsichtigkeit auf einem zweiten System passiert ist und von diesem dann alles verschlüsselt wurde.

    Da ich mit einigen Antiviren usw. (bitDefender wäre meine empfehlung! Stand 15.05.2018) drüber gefahren bin ist das System sauber aber ich kann leider nicht mehr sagen welches genau den PC befallen hat.

    Alle dateien enden mit .2226499124.ransomed@india.com und beim ausführen wird angezeigt das es eine MS-Dos anwendung sei.

    DateiTyp: MS-DOS-Anwendung (.com)
    2226499124 wäre ja meine ID bei den Spasten!
    ransomedia@india.com wird sicher nicht die Dateienendung sein.
