.Gryphon File Virus – Update September 2017

The “BlankSlate” malspam has been reported to push the .Gryphon File Virus. The malware campaign sends spam emails which contain an archive file as an attachment. The e-mail is written in a laconic way, so you as the potential victim gets curious enough to open it. Inside that archive file is another archive, usually in the form of a .zip file and finally the real contents are revealed. At the end, a .js script is waiting to be executed. If opened, the script will launch a download for the actual Gryphon ransomware and then infect your computer device. Most infections spotted are with the chines34@protonmail.ch email variant of the .Gryphon File Virus.

.Gryphon File Virus – Spread

The .Gryphon file virus could spread its infection via various methods. One of these methods is seen as the main one for spreading it, which is with a payload file that executes the malicious script for the ransomware, which in turn infects your computer system. Such a payload file can be seen distributed around the Internet and you can see an example of it being detected by security vendors as showcased down here:

The .Gryphon file virus could spread its payload file on social media sites and file-sharing networks. Freeware applications which are found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Avoid opening files straight away after you have downloaded them. That stands especially for ones that came from sources like suspicious e-mails or links. What you should rather do is to scan files before opening them with a security tool, while also checking their size and signatures for anything dubious. Also, you should read the ransomware prevention tips given in the forum section.

.Gryphon File Virus – Details

The .Gryphon file virus takes its name from the .Gryphon extension that it appends to all files which it encrypts. Some malware researchers are arguing if this virus is a variant of the the .BTCWare File Ransomware Virus or written on its code.

The .Gryphon file virus could make entries in the Windows Registry to achieve persistence, launch and repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each boot of the Windows Operating System, and one such entry is outlined down below:

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run

The ransom note will be placed inside your personal computer after the encryption process is complete. The note is written in English, but that doesn’t mean that the only target of the virus is the English-speaking users. Inside, you will view the payment instructions for allegedly recovering your files. The ransom note is written in a file called “HELP.inf”.

The HELP.inf file will show the following ransom note:

That ransom note reads the following:

GRYPHON RANSOMWARE
Your documents, photos, databases and other important files have been encrypted
cryptographically strong, without the original key recovery is impossible!
To decrypt your files you need to buy the special software – “GRYPHON DECRYPTER”
Using another tools could corrupt your files, in case of using third party
software we dont give guarantees that full recovery is possible so use it on
your own risk.

If you want to restore files, write us to the e-mail: decr@cock.li
In subject line write “encryption” and attach your ID in body of your message
also attach to email 3 crypted files. (files have to be less than 2 MB)

It is in your interest to respond as soon as possible to ensure the restoration
of your files, because we wont keep your decryption keys at our server more than
one week in interest of our security.

Only in case you do not receive a response from the first email address
withit 48 hours, please use this alternative email adress: decrsup@cock.ll

Your personal identification number:

The developers of the Gryphon ransomware are using two e-mail addresses as a way to contact them. As seen above in the ransom note message the two e-mail addresses used by the Gryphon cryptovirus are the following:

  • decr@cock.li
  • decrsup@cock.ll

Instructions presented in the ransom note of the .Gryphon file virus should not be followed. You should NOT under any circumstances write to the cybercriminals. Nobody could give you a guarantee that your files will get restored if you pay the ransom. However, you could try to get 3 of your files decrypted, in case you need to use them with a potential decryptor tool released in the future.

.Gryphon File Virus – Encryption

If the .Gryphon file virus ransomware is indeed a BTCWare variant or uses its code, it has a high probability to target and encrypt files that have the following extensions:

→.1c, .3fr, .accdb, .ai, .arw, .bac, .bay, .bmp, .cdr, .cer, .cfg, .config, .cr2, .crt, .crw, .css, .csv, .db, .dbf, .dcr, .der, .dng, .doc, .docm, .docx, .dwg, .dxf, .dxg, .eps, .erf, .gif, .htm, .html, .indd, .iso, .jpe, .jpeg, .jpg, .kdc, .lnk, .mdb, .mdf, .mef, .mk, .mp3, .mp4, .mrw, .nef, .nrw, .odb, .ode, .odm, .odp, .ods, .odt, .orf, .p12, .p7b, .p7c, .pdd, .pdf, .pef, .pem, .pfx, .php, .png, .ppt, .pptm, .pptx, .psd, .pst, .ptx, .r3d, .rar, .raw, .rtf, .rw2, .rwl, .sql, .sr2, .srf, .srw, .tif, .wb2, .wma, .wpd, .wps, .x3f, .xlk, .xls, .xlsb, .xlsm, .xlsx, .zip

Each file that gets encrypted will receive the .[decr@cock.li].gryphon extension or the .[chines34@protonmail.ch].gryphon extension appended to itself as a secondary extension. One person in the comments has reported that there is another email used by the ransomware developers again implemented as the ones mentioned above and ut into the encryption of files – .[payoff@cock.li].gryphon. Some malware researchers say that the algorithm being used for the encryption process is AES but that has not been confirmed as of yet.

Other e-mails that are used, which also end up being in the forming of the extension of encrypted files:

  • microcost@bigmir.net
  • microcost@protonmail.ch

The .Gryphon file virus is very possible to erase the Shadow Volume Copies from the Windows operating system. That will make the encryption process more viable since it will eliminate one way for a possible file restoration. Keep on reading to see what ways you can try out to potentially recover some of your file data.

Remove .Gryphon Virus and Restore Your Data

In case your computer got infected with the .Gryphon file virus, you should have some experience in removing malware. You should get rid of this ransomware as quickly as possible before it can have the chance to spread further and infect more computer systems.

    There is a new variant for this virus, it uses the email addresses:
    payoff@cock.li
    payoff@bigmir.net
    and files get the extension:
    filename.origextension.[payoff@cock.li].gryphon
    No decryption tool knows it yes – i have tried Kaspersky Decryptors, Emsisoft Decryptors and BTCWareDecrypter by Michael Gillespie.

    Here is how the encrypted files looks like:

    Any new information will be much appreciated.

      I see that there are no changes in the code of the ransomware, the ransom note, but just in the e-mail. The e-mail is also used as that secondary extension to encryt files. This is not a new variant, but more like a change in the current one or a version rather.

      I do not think that Michael Gillespie has updated the BTCware decrting tool yet. We will keep you posted if any new information surfaces, but know that there might be even 10 different emails put used for this variant of BTCware (Gryphon).
