Remove Cryp1 (UltraCrypter) Ransomware and Restore .Cryp1 Files

Latest Update! Malware researchers from Kaspersky have updated their Rannoh Decryptor utility with decryption for the CryptXXX 3.0 ransomware family. Files should be fully decrypted with the help of that software. You can find its download page and instructions at: Kaspersky’s Rannoh Decryptor page.
New Update! A possible glitch reveals the private decryption key Cryp1 (UltraCrypter) ransomware. You just need to enter your personal ID on the page and you should have the page saying that you have paid and give you the key. You can check this at – but if it does not say that you have paid – do not pay!
Update! It appears that TrendMicro have come up with a decrypter software for the CryptXXX 3.0 variant. It might work with Cryp1 (UltraCrypter) as well. Unfortunately, for now, it decrypts files only partially. You can learn more about it from TrendMicro’s support site.


CryptXXX 3.0 crypto-virus ransomware has a new version, that locks files with .cryp1 extension. Although it quickly gained popularity with the Cryp1 title, the true name of the ransomware is UltraCrypter.

After encrypting files on a compromised PC, it will give you a personal ID, which you enter in a Tor’s Onion site to supposedly get a decrypter after paying. To see how to remove the ransomware and what you might try to restore your files, you should read the full article carefully.

Cryp1 Ransomware – Ways of Distribution

Cryp1 ransomware has more than one distribution ways. The most effective one continues to be through exploit kits. The Angler exploit kit and Bedep exploit kit are still mostly responsible for the lightning fast distribution of this nasty crypto-virus. Only this time, other exploit kits are involved as well.

Like many of today’s world ransomware viruses, spam emails are a common tactic to compromise computers. The Cryp1 ransomware is no exclusion. These emails have files attached which spread the infection further. The file attachments usually contain some executable file with malicious code inside. The malicious code might be the ransomware itself, or another malware that is delivering files of the real threat to the infected machine.

Another popular way of distribution for the attacks of Cryp1 is through social media networks and file-share services. DropBox is a known medium for such infections, containing files, which are disguised as something harmless and useful. You should be on high alert when it comes to downloading, opening or clicking anything from an unknown source. A good prevention tip is to stay away from suspicious files and be wary around anything that seems out of place.

Cryp1 Ransomware – Origin

Cryp1 ransomware has an interesting backstory. It all began as CryptXXX and encrypted users’ files on a global scale. Kaspersky researchers made a decryptor tool and released it for free. Afterward, CryptXXX 2.0 came in play. The improved ransomware hit companies, business firms, schools, and hospitals. Kaspersky fought back with an improved version of their decryptor. People could take a breath for a bit, but it wasn’t long until the new variant CryptXXX 3.0 came into being.

The ransomware owners released the CryptXXX 3.0 variant in a desperate attempt to save their business. In all the haste, they broke their own decrypter, which users had to pay for to decrypt files. Now, in its current state, CryptXXX 3.0 has a new version, which probably has a working decrypter and fixed flaws. Rebranded as UltraCrypter, the ransomware continues to thrive.

Cryp1 Ransomware – Comprehensive Analysis

Cryp1 is a crypto-virus ransomware. In other words, it reproduces just like a human virus, trying to infect more and more data; it encrypts user files; it asks for money to be paid as ransom. As already mentioned above, its real name is UltraCrypter. Circling the Web is the name Cryp1, which has gained more popularity. People have named it so, because of the extension it places on files – .cryp1.

UltraCrypter actually goes by many names and the most popular are:

  • Cryp1 Ransomware
  • Crypt1 Ransomware
  • Crypt Ransomware
  • UltraCrypter
  • UltraDeCrypter
  • CryptXXX 3.0 (ver. 2)

A file !(Hex code ID).html is created after a successful encryption, where the file name is random. The name is created out of the hexadecimal values formed by the malware in each infected computer. The malware researcher Michael Gillespie has shared his unique hex ID in one of his twitter posts.

The file !([0-9A-F]{12}).html as described above, opens a browser to display the html code in a browser webpage. It does that so the links given inside are clickable. This file copies itself around multiple locations that have encrypted files. It also has the same file with the text made into a .bmp picture that is placed as a desktop background at the end of the encryption process.

You can see the .bmp file’s preview from the image here:


The file has different hyperlinks and a different version of the sites, which probably either redirect or the cyber criminals have bought a multitude of domains. An example of the file in question reads the following:

All your files are encrypted.

ID: [Your personal ID is given here]


Download and install tor-browser

TorLink: http://eqyo4fbr5okzaysm(.)onion

Write down the information to notebook (exercise book) and reboot the computer.

If you click on any of the weblinks that are provided, you will be sent to the following page:


Entering your personal ID number will let you into the system. Inside, you will find the following instructions with the full payment instructions:

Your files are encrypted
If you do not pay for decrypting until [Date], the decryption cost will increase 2 and will be 1008 USD

96 hours remaining

We present you a special software – UltraDeCrypter that will allow you to decrypt your files.
How to buy UltraDeCrypter?
1. You can pay using Bitcoin, getting them by the way most convenient for you.
2. You need to create a Bitcoin-wallet (e-wallet or other method).
3. Buy Bitcoin on one of the trading platforms.
4. Send 1.2 BTC to Bitcoin address.
5. Enter the ID of your Bitcoin-transaction.
6. Please check payment information you mentioned and click on “PAY” (Attention! Do not provide incorrect information! Otherwise, the payment amount will be increased by several times, or your account will be blocked!)

From the quoted information above, it is easy to see that the initial price asked is 1.2 BitCoins or the equivalent of ~500 US dollars. You have four days to pay the ransom, which is 96 hours. If you don’t pay, the price gets increased, but there are no threats that your files are going to be lost or erased.

Judging from the text, it seems that now the Cryp1 ransomware has a working decrypter tool, or it only seems that way. The tool is called UltraDeCrypter.

Do NOT pay these crooks. Supporting criminals is not in any way good. You will only help them in making a stronger variant or other ransomware with fewer flaws. Nobody can say with certainty that you can restore your files with their decrypter, or that it will actually work. Kasperksy have beaten this ransomware twice, so there is a high chance they will do it again. Meanwhile, if you want to see how you can try to restore some of your files, read till the end.

The Cryp1 ransomware possibly encrypts files with the same extensions as CryptXXX 3.0. These extensions can be seen in the following list:

→.3dm, .aes, .ARC, .asc, .asf, .asm, .asp, .avi, .bak, .bat, .bmp, .brd, .cgm, .class, .cmd, .cpp, .crt, .csr, .CSV, .dbf, .dch, .dcu, .dif, .dip, .djv, .djvu, .doc, .DOC, .docb, .docm, .docx, .DOT, .dotm, .dotx, .eml, .fla, .flv, .frm, .gif, .gpg, .hwp, .ibd, .jar, .java, .jpeg, .jpg, .key, .lay, .lay6, .ldf, .max, .mdb, .mdf, .mid, .mkv, .mml, .mov, .mp3, .mp4, .mpeg, .mpg, .ms11, .MYD, .MYI, .NEF, .obj, .odb, .odg, .odp, .ods, .odt, .otg, .otp, .ots, .ott, .PAQ, .pas, .pdf, .pem, .php, .png, .pot, .potm, .potx, .ppam, .pps, .ppsm, .ppsx, .PPT, .pptm, .pptx, .psd, .qcow2, .rar, .raw, .RTF, .sch, .sldx, .slk, .sql, .SQLITE3, .SQLITEDB, .stc, .std, .sti, .stw, .svg, .swf, .sxc, .sxd, .sxi, .sxm, .sxw, .tar, .tar, .bz2, .tbk, .tgz, .tif, .tiff, .txt, .uop, .uot, .vbs, .vdi, .vmdk, .vmx, .vob, .wav, .wks, .wma, .wmv, .xlc, .xlm, .xls, .XLS, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml, .zip, .zipx


The list above might be incomplete because we are talking about a new version after all. When the encryption process finishes, all your files will have another extension added as an appendix – .cryp1. The creators of the ransomware have cleverly written .crypt again but in a more creative way. Except that resemblance, there are other indicators that this is indeed a version of CryptXXX 3.0.

Cryp1 ransomware deletes Shadow Volume Copies from the Shadow Explorer process used in the Windows Operating System.

Hopefully, researchers will make a decrypter for the ransomware as they did with previous variants of CryptXXX. Read on, to find out what you can do about your files in the meantime.

Remove Cryp1 Ransomware and Restore .cryp1 Encrypted Files

In case your computer is infected with the Cryp1 (UltraCrypter) ransomware, you should have some experience in removing viruses. You should get rid of Cryp1 ransomware as soon as you can, because it can keep encrypting more and more files. Even worse, if not removed quickly it could spread into the network and reach a lot of other PCs. The recommended action is for you to remove the ransomware and then follow the step-by-step instructions given here.

    It angers me – ransomware’s unprecedented evolution. I truly hope that reverse engineers and security researchers will succeed in “resolving” all current ransomware infections. We need active anti-ransomware protection more than ever.

      i am not techincian guy but I Wonder if it is so impossible to track those crooks using their ransom id for payment. it means to find IP address who received such transfer.
      Is it difficult to create software tracking such transfers?
      If they are using bitcont transfer isn’t it possible to develop such bitcoin wallet to have possibility to track tchem.

      1. AvatarMilenaDimitroff

        I am sure that security experts are doing whatever they can to track down cyber crime gangs. When institutions cooperate, it usually leads to arrests…For instance, last year Kaspersky collaborated with the Dutch police, and eventually they arrested suspects on the CoinVault case. However, things get more complicated with later ransomware cases, as cyber criminals gain more experience and quickly fix holes in their viruses, and release new versions of the same virus…and the story continues…

  2. AvatarGergana Ivanova

    The case “.crypt” has transformed into a long story. The development of Cryp1 or UltraCrypter ransomware sounds like a logical sequence of the story about the criminals. Тhey certainly were not happy when the news about their broken decrypter had spread around the net. Unfortunately, it is evident that they have discovered a new way to harass users and demand money.
    Think about the preventive measures that concern your online security. Don’t forget to implement them every time you use your PC and be a step ahead of the crooks. So, do you feel protected?

    I had last week my files, pictures and others encryption.. all my files… .cryp 1
    Do you know the tool to decrypt the files?
    Because de hackers sendme a bad ID to use at dipweb to pay the ranson, and now Im desespareted.
    I wait for answer.
    Thanks so much.

      Hello Tati,

      Can you provide us with more information regarding your interaction with the hackers?

      What ID did they send you that didn’t work? CryptXXX 3.0 (the previous version of this ransomware) also had a decrypter that didn’t work.

      For now there is only the decrypter of TrendMicro as stated in the update at the very beginning of the article. Their tool doesn’t recover files fully. The article will be updated if such a tool is found.

        On 05.31.2016 after lunch had my machine invaded by Malware Ransoware in a matter of minutes he encrypted
        my files of images, documents, .txt among others, in addition to the original extension of my file Ransoware the added length
        .cryp1 and each of them, for example the original file name with DSC0001.jpg turned DSC0001.jpg.cryp1 and therefore did not have more access to them.
        After restarting the machine the Ransoware added a wallpaper showing the way he should go to try the rescue with the given ID.
        I tried this but I did not succeed because the ID did not work, tried on more than one machine to ensure, and it did not work.
        Well, I ask for help, please, photos are my life, I am very sad, this is killing me.

        I await comments, please help me!

          Hello Tati,

          Sorry for the late response but we have been busy.

          Thank you for providing more information about your case.

          However, we wanted to know about your communication with the criminals after you got infected. Did you only use the system they provided for paying or did you have a conversation with the criminals as well? If you received a non-working key, do you mind sending it to us?

          We hope you didn’t format your computer, so you might be able to recover some files with a Data Recovery software. Some examples of such software are provided inside the article’s Restore section of the instructions.

          Best Regards,

            Last Friday I joined the dipweb site with the key, and then on Monday beast sent the sample file for descriptografarem criminals as saying on the site before paying the bitcoins, but they failed to decrypt the file, the same continues as (wait …), if you can use the id that I received and go to check.
            Not formatted my HD, I will wait, even if you have to save for years my pictures to get a key that decrypts my files.

            My key is ID 68F0D99F1937

            you want I sent the pictures of all my case ?, because I captured via print all events.

            Thanks so much.

            Hello again, Tati.

            Unfortunately, even with the ID you shared, it seems files cannot be decrypted from the criminals site. You can provide pictures, but other researchers report that the ransomware owners’ decryption doesn’t work.

            Your best bet is to try the Free TrendMicro decrypt tool (there is a link at the start of the article) and after that the Data Recovery Tools we mentioned in the above comment. In that way, you should be able recover at least .doc files and pictures – not sure to what extent though.

            Best Regards,
