What is Mark file
.[email@example.com].Mark is a file extension that uses a new malware belonging to the Crysis/Dharma ransomware family to mark files that have been encrypted. Ransomware is a malicious program that encrypts user files and demands a ransom for a key-decryptor pair that is necessary to decrypt the affected files. Ransomware uses a strong encryption system and a long key, which virtually eliminates the possibility of decrypting files without a key. Files encrypted with .[firstname.lastname@example.org].Mark extension become useless, their contents cannot be read without the key that the criminals have.
What is Mark ransomware virus
Mark virus is one of the variants of Dharma/Crysis ransomware. This malware most often gets to the computer as part of other programs (torrents files, freeware, cracked apps and games) that have been downloaded by the user from the Internet. After its start, the virus begins to encrypt files using a key that is individual for each computer. Mark virus uses a very strong encryption system, which eliminates the possibility of determining the key, even using a super computer. The encryption process is very fast, regardless of what is in the file, the virus can easily encrypt it. Mark can encrypt almost all files that are on the computer, including those located on network drives. The only thing that the virus does not encrypt is the files that are necessary for the Windows OS to function normally. Below we list the types of files that can be encrypted by the ransomware:
.avi, .3dm, .qdf, .wpw, .rb, .mdbackup, .upk, .pptm, .bc7, .xbdoc, .xlgc, .yml, .kdc, .wmf, .t12, .xlsx, .1, .wmd, .xmind, .fsh, .kdb, .wot, .pak, .xlsm, .litemod, .ai, .icxs, .eps, .jpe, .p12, .itdb, .rwl, .slm, .dcr, .blob, .y, .wmo, .odm, .esm, .wav, .zdb, .desc, .sis, .arch00, .bar, .xlk, .rgss3a, .wri, .wpd, .1st, .odt, .wmv, .txt, .wpe, .vtf, .wbk, .ltx, .re4, .xlsb, .odp, .xf, .p7c, .epk, .ybk, .raw, .map, .arw, .wb2, .wbm, .xmmap, .ppt, .xwp, .wcf, .kf, .ibank, .png, .vfs0, .pem, .wps, .3ds, .cas, .syncdb, .webdoc, .ws, .m3u, .tax, .lrf, .ysp, .ztmp, .dazip, .itm, .wdb, .xx, .zi, .db0, .xls, .xxx, .bik, .ods, .xar, .hplg, .pst, .lvl, .accdb, .zip, .mlx, .sr2, .zw, .z3d, .erf, .wbz, .rim, .tor, .ncf, .bay, .xbplate, .7z, .wmv, .bc6, .rw2, .xml, .sum, .3fr, .wpt, .sie, .js, .xy3, .cfr, .xlsm, .wbmp, .zif, .forge, .xll, .yal, .wire, .doc, .cdr, .py, .wn, .flv, .rar, .sav, .mdf, .wp, .srf, .apk, .dbf, .xld, .wp7, .lbf, .m4a, .cer, .srw, .vcf, .z, .wsh, .itl, .mrwref, .csv, .big, .crw, .xyw, .raf, .dba, .mpqge, .docx, .wbd, .xls, .hkx, .bkp, .xdl, .sql, .sidn, .wbc, .wma, .wp5, .jpeg, .wdp, .bsa, wallet, .dmp, .indd, .zdc, .hvpl, .vdf, .mef, .x3f, .wpd, .rtf, .ff, .fpk, .r3d, .wp6, .wma, .webp, .mp4, .t13, .nrw, .mdb, .mcmeta, .pkpass, .wps, .xpm, .wpb, .menu, .wpa, .asset, .pef, .sid, .d3dbsp, .vpk, .mov, .odc, .p7b, .wsd, .wgz, .wm, .w3x, .gdb, .xdb, .ptx, .sb, .gho, .sidd, .x3f, .pfx, .pdf, .vpp_pc, .cr2
When the file is encrypted, ‘.id-USERID.[EMAIL-ADDRESS].Mark’ is added at the end of its name, that is, if you had a file of ‘document.docx’, then a file with the name ‘document.docx.id-USERID.[EMAIL-ADDRESS].Mark’ will appear in its place. If you change the file name, just delete the added extension, then nothing will change. The file will remain encrypted, and as before, this file will not be possible to open in the program with which it is associated.
Perhaps you found on your computer or its desktop a new file called ‘FILES ENCRYPTED.txt’, which for some reason is not encrypted. An example of such a file is given below.
all your data has been locked us
You want to return?
write email email@example.com or firstname.lastname@example.org
This file is very important, in addition to containing a ransom demand, it also contains information that allows you to contact intruders. According to the message, the victim is invited to contact the attackers using the given email address. In response, the authors of the virus will give a Bitcoin address to which the ransom must be transferred. Of course, you should understand that there is no guarantee that the attackers, after receiving the ransom, will provide you with the key necessary to decrypt your files. In addition, by paying the ransom, you will push attackers to create a new ransomware.

As we have already said, Mark virus is not the first in its series. The fact that to date, antivirus companies have not created a way to decrypt files, and just have not found a 100% way to protect the user’s computers (otherwise how would you be on our site), indicates the complexity of the virus and the method that it uses to encrypt files. Nevertheless, you do not need to despair. There are several ways to find and remove Mark ransomware, and there is also a chance to restore part or even all encrypted files to their original state. Below we will describe in detail how to do this.

How to decrypt .[firstname.lastname@example.org].Mark files
All files with the ‘.[email@example.com].Mark’ extension are encrypted. Their contents cannot be unlocked simply by removing this extension or completely changing the filename. Unfortunately, as we already reported in this article, there is currently no way to decrypt files. The reason for this is the complexity of the encryption algorithm that the authors of Mark virus use. In principle, this is what the attackers sought. But this does not mean that you have no choice and you need to pay a ransom for your files.
Never pay the ransom! Any security expert will tell you this. Of course, there is a chance that by paying a ransom, Mark virus authors will allow you to unlock your files, but there is no guarantee. Moreover, you should understand that when you pay a ransom, you unknowingly push the attackers to create new, even more destructive viruses.
Do not forget that besides you, thousands more people around the world have lost their files, that is, you are not alone. Antivirus companies, secuity experts are working on something that will allow you to decrypt .[firstname.lastname@example.org].Mark files. Perhaps in the future an universal method will be developed that will allow all victims to unlock all their data.
Of course, as soon as a way to decrypt the files appears, we will post a message about this to this article or to our facebook account. Therefore, we recommend that you follow the updates.
How to restore .[email@example.com].Mark files
As we wrote above, you cannot decrypt files encrypted with this virus. But you can use a different way, there is a small chance to restore .[firstname.lastname@example.org].Mark files without decrypting them. Programs created for searching and recovering lost and deleted data can help you with this. We offer you to use the following free programs: PhotoRec and ShadowExplorer. Only two things that I want to say additionally. First, before restoring files, you must be 100% sure that there is no ransomware on the computer. We recommend using free malware removal tools that we examined in this article. Second, and what is very important! The less you use your computer after ransomware infection, the higher the chance that you will be able to recover encrypted files.
Use shadow copies to restore .[email@example.com].Mark files
First of all, try to recover your files using a free tool called ShadowExplorer. This program will allow you to recover your files from Shadow Volume Copies. These copies are created automatically by the OS when you work with your files. Unfortunately, very often, the virus automatically deletes all these copies and thus prevents the user from recovering exnrypted files. Nevertheless, in some cases, the ransomware cannot delete all copies, and the user gets the opportunity to quickly restore all files. Therefore, our opinion, you should definitely try this method!
Download ShadowExplorer by clicking on the following link.
Category: Security tools
Update: September 15, 2019
After the download is complete, extract the saved file to a folder on your computer. This will create the necessary files as displayed below.
Launch the ShadowExplorerPortable program. Now select the date (2) that you want to recover from and the drive (1) you want to recover files (folders) from as shown below.
On right panel navigate to the file (folder) you wish to recover. Right-click to the file or folder and click the Export button like below.
And finally, specify a folder (your Desktop) to save the shadow copy of encrypted file and click ‘OK’ button.
Use PhotoRec to restore .[firstname.lastname@example.org].Mark files
Another really working way to recover your encrypted files is to use a program named PhotoRec. It is created to recover deleted or lost files. Does the virus block this method? Fortunately, the Mark virus cannot block it in any way. Why is this possible you ask. This is possible for the reason that when you delete files using the standard OS function, these files are not actually deleted. Just the Windows marks them as deleted and does not show them in the list of files. The program that we suggest you use, finds deleted files, including files that were deleted by the ransomware, and recovers them.
Download PhotoRec on your personal computer by clicking on the following link.
Category: Security tools
Update: March 1, 2018
When the downloading process is complete, open a directory in which you saved it. Right click to testdisk-7.0.win and select Extract all. Follow the prompts. Next please open the testdisk-7.0 folder as displayed in the following example.

Select a drive to recover as displayed on the image below.
You will see a list of available partitions. Choose a partition that holds encrypted documents, photos and music as displayed in the following example.
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 done, press OK button.
Next, click Browse button to select where restored files should be written, then click Search.
Count of restored 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 restore process is not finished.
When the recovery is finished, click on Quit button. Next, open the directory where recovered files are stored. You will see a contents like the one below.
All restored 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 recovered files by extension and/or date/time.
