What is Craftul ransomware? And how does it execute its attack?
Craftul ransomware is a new file-encrypting threat that was first spotted in the last week of June 2019. According to crypto malware experts, it seems to be a new and improved version of Stroman ransomware. It uses a “craftul” suffix in the files it encrypts as well as the RSA 1024 encryption algorithm in locking files. It has similarities with other ransomware threats like Insta ransomware but it is yet to be proven.
The second its malicious payload is dropped in the system, it begins to execute its attack by adding more malicious files and placing them on system folders to prevent any programs from interrupting its attack. It also modifies the Windows Registry in order to run on every system boot. Once these changes are applied, it will start to scan the computer looking for files with the following formats:
.3gp, .7z, .apk, .avi, .bmp, .cdr, .cer, .chm, .conf, .css, .csv, .dat, .db, .dbf, .djvu, .dbx, .docm, doc, .epub, .docx .fb2, .flv, .gif, .gz, .iso .ibooks,.jpeg, .jpg, .key, .mdb .md2, .mdf, .mht, .mobi .mhtm, .mkv, .mov, .mp3, .mp4, .mpg .mpeg, .pict, .pdf, .pps, .pkg, .png, .ppt .pptx, .ppsx, .psd, .rar, .rtf, .scr, .swf, .sav, .tiff, .tif, .tbl, .torrent, .txt, .vsd, .wmv, .xls, .xlsx, .xps, .xml, .ckp, .zip, .java, .py, .asm, .c, .cpp, .cs, .js, .php, .dacpac, .rbw, .rb, .mrg, .dcx, .db3, .sql, .sqlite3, .sqlite, .sqlitedb, .psd, .psp, .pdb, .dxf, .dwg, .drw, .casb, .ccp, .cal, .cmx, .cr2
Once it finds its targeted files, it will begin the encryption process by applying the AES 256 cipher in encoding the files. Following data encryption, it appends the .craftul extension to every encrypted file and generates a file named “FilesInfo.txt” which contains the following message:
“All your important files were encrypted on this PC.
All files with the .craftul extension are encrypted.
Encryption was produced using the unique private key RSA-1024 generated for this computer.
To decrypt your files, you need to obtain a private key + decrypt software.
The single copy of the private key, with will allow you to decrypt the files, is located on a secret server on the internet.
To retrieve the private key, you need to contact us by email at [email protected] send us an email your FilesInfo.txt file, and wait for further instructions.
For you to be sure, that we can decrypt your files – you can send us 1-2 not very big encrypted files and we will send you back it in a decrypted form free.
To send files you can use hxxp://dropmefiles.com/
Do not waste your time! After 72 hours the main server will double your price!
