CryptoShadow Ransomware – Delivery Tactics

CryptoShadow ransomware might get delivered with different tactics. The dropper for the payload file which initiates the malicious script for the ransomware can be found around the Web by the name iexplorer.exe, and it can be renamed to hide itself. You can see the analysis of that executable file from the screenshot of the VirusTotal website, down here:

CryptoShadow ransomware might be using other delivery tactics, such as spreading the payload file dropper through social media and file-sharing websites. Freeware applications which roam the Internet could be presented as useful but also could hide the malicious files of the virus. Don’t open files immediately after you have downloaded them, especially if they come from unverified and unknown sources, such as links and e-mails. You should always scan the files with a security tool before opening them, and check their sizes and signatures for anything that seems unusual. You should read the ransomware preventing tips thread in the forum.

CryptoShadow Ransomware – Detailed Overview

CryptoShadow ransomware is a cryptovirus, that is a variant of the open-source ransomware project HiddenTear, according to malware researchers. When the CryptoShadow ransomware encrypts your files, it will append the extension .doomed to them as an extension on each encrypted file.

CryptoShadow ransomware might make entries in the Windows Registry to achieve perseverance. These registry entries are typically designed in a way that will start the virus automatically with each launch of the Windows Operating System.

The ransom note with instructions is found inside the following file:

  • LEER_INMEDIATAMENTE

That ransom note reads the following:

Sus archivos fueron encryptados por CryptoShadow, vea el archivo exe para mas informacion!.

Files related to the ransomware are found on the address “http://crypt0sh4d0w.890m.com/ransomphp/sha256/write.php

The developers of the CryptoShadow virus are probably targeting Spanish-speaking users. However, nobody is immune to getting infected by this ransomware. You should NOT in any case contact the cyber criminals or pay them as no guarantee exists that you will recover your files. Providing money to those crooks will probably just support them financially and inspire them to do more criminal acts.

For the moment, there is no list of file extensions that the CryptoShadow ransomware searches to encrypt. The encryption algorithm which is used is believed to be AES and malware researchers say that the ransomware is a variant of the HiddenTear open-source project. Encrypted files will receive the .doomed extension appended to them. The following extensions are possible of becoming encrypted:

→.txt, .doc, .docx, .xls, .xlsx, .pdf, .pps, .ppt, .pptx, .odt, .gif, .jpg, .png, .db, .csv, .sql, .mdb.sln.php, .asp, .aspx, .html, .xml, .psd, .frm, .myd, .myi, .dbf, .mp3, .mp4, .avi, .mov, .mpg, .rm, .wmv, .m4a, .mpa, .wav, .sav, .gam, .log, .ged, .msg, .myo, .tax, .ynab, .ifx, .ofx, .qfx, .qif, .qdf, .tax2013, .tax2014, .tax2015, .box, .ncf, .nsf, .ntf, .lwp

A high possibility for the CryptoShadow cryptovirus is to delete the Shadow Volume Copies from the Windows operating system with using the following command in CommandPrompt:

→vssadmin.exe delete shadows /all /Quiet
