Remove TeslaCrypt 3.0 Ransomware and Restore .mp3 Encrypted Files

One of the most vicious malware threats ever to affect users on a global scale – TeslaCrypt ransomware, has appeared yet again with another variant. This time, the crypto-malware uses a .mp3 file extension and possibly employs improvements in its code. Such improvements may make the decryption process even more difficult. Despite the fact that TeslaCrypt demands ransom money to unlock the encrypted files on a victim’s computer, we strongly advise users not to pay. Instead, keep trying with the methods we regularly update in our removal articles to restore files.

UPDATE! A free decryptor has been released for files encoded by TeslaCrypt 3.0 ransomware. To learn how to decrypt your files, please visit the following article.

TeslaCrypt 3.0 Ransomware – How Does It Spread

TeslaCrypt is mainly spread via exploit kits and Trojans, such as the Miuref.B Trojan. These can be found attached to an email the victim may have opened as a malicious URL or a spam attachment of an archive file. It may contain either infected document files or malicious URLs that lead to such. The most commonly used malicious files are of the following file extensions:

  • .bat, .cmd, .dll, .tmp, .exe

The spam emails featured may resemble a legitimate service the user has been registered in. Examples may be as follows:

  • “Your payment receipt from PayPal.”
  • “Free gift from eBay.”
  • “Bank Reciept from {Bank Name}.”

TeslaCrypt 3.0 Ransomware In Detail

Unlike other Tesla variants, this one is more sophisticated. This is because, besides using CryptoWall’s ransom note, to resemble another devastating malware, TeslaCrypt supports a significantly larger range with file extensions that it can encrypt.

TeslaCrypt performs the following methodological steps when it infects your computer:

Step 1: Payload Drop

The payload has random characters, and it is located in:

  • %User’sProfile%\Application Data

TeslaCrypt 3.0 then makes a registry entry for the .exe to run every time Windows has started. It is located in the following key:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\run\

And it is set with the following data:

  • “addon_v{number}” = “%User’sProfile%\Application Data\{payload .exe}

After this the crypto-malware also makes a registry entry with hexadecimal digits in the following key:

  • HKEY_CURRENT_USER\Software\xxxsys\

Step 2: File Encryption

According to Symantec Threat Response researchers, once its malicious .exe has been started, the crypto-malware then scans for and encrypts files with these extensions:

.7z .rar .m4a .wma .avi .wmv .csv .d3dbsp .sc2save .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 .mcgame .vdf .ztmp .sis .sid .ncf .menu .layout .dmp .blob .esm .001 .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 .DayZProfile .rofl .hkx .bar .upk .das .iwi .litemod .asset .forge .ltx .bsa .apk .re4 .sav .lbf .slm .bik .epk .rgss3a .pak .big .unity3d .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 .dbfv .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

TeslaCrypt adds the .mp3 file extension to the files, for example:

  • New Excel Worksheet.docx.mp3

The files appear to be corrupt and upon opening the user may witness that Windows begins to look for a way to open them:

mp3-player-sensorstechforum-files-.mp3-file extension

When the file is checked, it is becoming clear that a very strong mixture of AES-256, SHA256 and ECHD encryption algorithms have been used:


In addition, the ransomware creates a “__sys_{random numbers}” mutex and then connects to several remote hosts:

  • http://ladiesdehaan(dot)be/modules/mod_cmscore/mzsy
  • http://chonburicoop(dot)net/tmp/mzsy
  • http://ferienwohnung-walchensee-pur(dot)de/tmp/mzsy
  • http://espoirsetvie(dot)com/modules/mod_cmscore/mzsy
  • http://ioasis(dot)org/modules/mod_fxprev/libraries/mzsy
  • http://polyhedrusgroup(dot)com/components/com_acymailing/views/user/tmpl/mzsy

Step 3: Notifying the user:

After finished with the encryption of the data, TeslaCrypt, creates several files:

  • recover_file_{random_ID}.txt

The _H_e_l_p_RECOVER_INSTRUCTIONS{ID} files all contain the following ransom note:

TeslaCrypt 3.0 Ransom Note

”What happened to your files?
All of your files were protected by a strong encryption with RSA-4096.
More information about the encryption keys using RSA-4096 can be found here:
How did this happen?
!!! Specially for your PC was generated personal RSA-4096 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 BTC 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.

The “recover_file.txt” contains four lines of identification numbers, which represent accordingly the following information:

  • The BitCoin address.
  • The hex code for the public AES key which is 32 bytes in size.
  • ID hex.
  • ID of the used encryption.

Remove TeslaCrypt 3.0 and Restore .mp3 Encrypted Files

The bottom line is that the latest variant of Tesla has definitely improved and may have patched up several holes and weaknesses in its code, leaving the user without any way out but to decrypt his files.

However, experts strongly advise NOT to pay any ransom money for the following reasons:

  • You fund the cybercrime organization and it makes the ransomware even more impenetrable.
  • There is no guarantee that your files will be decrypted after you pay the ransom money.

It is strongly recommended to immediately remove this malware by using the methods outlined after this article. In them we have also included instructions on how to use different software to recover your files.

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:
