A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected. You can see the detections of such a file on the VirusTotal service right here:

SyncCrypt ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them.

SyncCrypt Ransomware – Analysis

SyncCrypt is a virus that encrypts your files and extorts you to pay a ransom to supposedly recover them. You are given a number of contact details, including multiple email addresses but you shouldn’t reach out to the cybercriminals as they will demand payment.

The ransomware will create the following files and put them inside a folder called “README” placed on your Desktop:

  • readme.html
  • readme.png
  • KEY
  • AMMOUNT.txt

SyncCrypt ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows Operating System.

That ransom note is inside the following two files:

  • readme.html
  • readme.png

The note can be previewed right down here, from the following screenshot:

The note reads the following:

using military grade encryption. The encrypted files have the additional extension .kk. You won’t be able to retrieve your data unless you purchase the software provided by us. YOU HAVE EXACTLY 48 HOURS TO MAKE A DECISION OR YOU’LL NEVER SEE YOUR FILES AGAIN. Any atempt to recover your files on your own could damage the files permanently. There is no workaround, that’s how encryption is supposed to work. In order to retrieve your data, please follow the steps below:
1. Go to Desktop folder, and open AMMOUNT.txt from within README folder. Obtaining the decryption sofware requires that you send EXACTLY the ammount of Bitcoin (without the transaction fee) that is written within the text file to the following address:
Note that if the ammount sent doesn’t match EXACTLY the ammount in the text file, you will NOT receive the sofware, as it’s the only way to validate and confirm the payment.
2. After the payment is done, send an email to ALL of the following addresses [email protected], [email protected], [email protected] containg:
The file named KEY, located within the README folder on your Desktop, as an Attachment – this file is a locked version of the decryption key (that must be unlocked by us), used to recover your files. DO NOT delete it if you plan to get your files back
The transaction id of the Bitcoin payment
Emails that dont contain the KEY file attached will be automatically rejected.
As soon as we confirm the payment, you will receive on your email address the decription key together with the required software and the instructions to recover your files.

The note of the SyncCrypt ransomware states that your files are encrypted. You are demanded to contact the following e-mail to supposedly recover your files, after paying:

The ransom sum that you are supposed to pay might differ between demanded to be paid in the Bitcoin currency. However, you should NOT under any circumstances pay anything. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware viruses and make them prone to commit similar cybercrimes.

SyncCrypt Ransomware – Encryption

The encryption process of the SyncCrypt ransomware is utilized with the help of the AES encryption algorithm or at least that is stated inside the ransom note. It will encrypt your files while placing the .kk extension to all locked files.

The targeted extensions of files which are sought to get encrypted are the following:

→accdb, .accde, .accdr, .adp, .ach, .arw, .asp, .aspx, .backup, .backupdb, .bak, .bat, .bay, .bdb, .bgt, .blend, .bmp, .bpw, .cdf, .cdr, .cdr3, .cdr4, .cdr5, .cdr6, .cdrw, .cdx, .cer, .cfg, .class, .cls, .config, .contact, .cpp, .craw, .crt, .crw, .css, .csv, .d3dbsp, .dbx, .dcr, .dcs, .dds, .der, .dif, .dit, .doc, .docm, .docx, .dot, .dotm, .dotx, .drf, .drw, .dwg, .dxb, .dxf, .edb, .eml, .eps, .fdb, .flf, .fpx, .frm, .gif, .gpg, .gry, .hbk, .hpp, .html, .hwp, .jpe, .jpeg, .jpg, .kdbx, .kdc, .key, .jar, .java, .laccdb, .latex, .ldf, .lit, .lua, .mapimail, .max, .mbx, .mdb, .mfw, .mlb, .mml, .mmw, .midi, .moneywell, .mocha, .mpp, .nef, .nml, .nrw, .oab, .odb, .odc, .odf, .odg, .odi, .odm, .odp, .ods, .odt, .otg, .oth, .otp, .ots, .p12, .pas, .pab, .pbm, .pcd, .pct, .pcx, .pdf, .pef, .pem, .pfx, .pgm, .php, .pict, .pntg, .potm, .potx, .ppam, .ppm, .pps, .ppsm, .ppsx, .ppt, .pptm, .pptx, .ppz, .prf, .psd, .ptx, .pub, .qbw, .qbx, .qpw, .raf, .rtf, .safe, .sav, .save, .sda, .sdc, .sdd, .sdf, .sdp, .skp, .sql, .sqlite, .sqlite3, .sqlitedb, .stc, .std, .sti, .stm, .stw, .sxc, .sxg, .sxi, .sxm, .sxw, .tex, .txt, .tif, .tiff, .vcf, .wallet, .wb1, .wb2, .wb3, .wcm, .wdb, .wpd, .wps, .xlr, .xls, .xlsb, .xlsm, .xlsx, .xlam, .xlc, .xlk, .xlm, .xlt, .reg, .rspt, .profile, .djv, .djvu, .ms11, .ott, .pls, .png, .pst, .xltm, .xltx, .xlw, .xml, .r00, .7zip, .vhd, .aes, .ait, .apk, .arc, .asc, .asm, .asset, .awg, .back, .bkp, .brd, .bsa, .bz2, .csh, .das, .dat, .dbf, .db_journal, .ddd, .ddoc, .des, .design, .erbsql, .erf, .ffd, .fff, .fhd, .fla, .flac, .iif, .iiq, .indd, .iwi, .jnt, .kwm, .lbf, .litesql, .lzh, .lzma, .lzo, .lzx, .m2ts, .m4a, .mdf, .mid, .mny, .mpa, .mpe, .mpeg, .mpg, .mpga, .mrw, .msg, .mvb, .myd, .myi, .ndf, .nsh, .nvram, .nxl, .nyf, .obj, .ogg, .ogv, .p7b, .p7m, .p7r, .p7s, .package, .pages, .pat, .pdb, .pdd, .pfr, .pnm, .pot, .psafe3, .pspimage, .pwm, .qba, .qbb, .qbm, .qbr, .qby, .qcow, .qcow2, .ram, .rar, .ras, .rat, .raw, .rdb, .rgb, .rjs, .rtx, .rvt, .rwl, .rwz, .scd, .sch, .scm, .sd2, .ser, .shar, .shw, .sid, .sit, .sitx, .skm, .smf, .snd, .spl, .srw, .ssm, .sst, .stx, .svg, .svi, .swf, .tar, .tbz, .tbz2, .tgz, .tlz, .txz, .uop, .uot, .upk, .ustar, .vbox, .vbs, .vcd, .vdi, .vhdx, .vmdk, .vmsd, .vmx, .vmxf, .vob, .vor, .wab, .wad, .wav, .wax, .wbmp, .webm, .webp, .wks, .wma, .wp5, .wri, .wsc, .wvx, .xpm, .xps, .xsd, .zip, .zoo

The SyncCrypt cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

If the above-stated command is executed, the encryption process will become more efficient. That is due to the fact that the command will eliminate one of the prominent ways to restore your data.
