What is Worlddecoding Ransomware?

Secneurx Analysts found the Worlddecoding ransomware in the wild and analyzed the sample. This ransomware exhibits several similarities and overlaps with World2022decoding Ransomware. Worlddecoding ransomware encrypts files and appends its extension (".worlddecoding") to filenames. Also, it drops the "WE CAN RECOVER YOUR DATA.MHT" file that contains a ransom note. After executing the Worlddecoding ransomware all files and folders got encrypted and appended their filenames with a ".worlddecoding" extension. For example a file titled as "Sep2019.docx" appeared as "Sep2019.docx.worlddecoding", "Jan2020.docx" as "Jan2020.docx.worlddecoding", and so on.

Worlddecoding Ransomware Overview

Worlddecoding ransomware notes inform victims that their files have been encrypted. It instructs victims to purchase an unique private key for decrypt the files and also mentioned an email address("”) and jabber account address ("") in ransomware note.

How does ransomware infect my computer?

Malware (ransomware included) is spread using phishing and social engineering tactics. Malicious programs are typically presented as or bundled with ordinary content. Infectious files can be executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), Microsoft Office and PDF documents, JavaScript, and so on. When a virulent file is executed, run, or otherwise opened - the infection process is jumpstarted.

YOUR FILES ARE ENCRYPTEDYour files, documents, photos, databases and other important files are encrypted.

You are not able to decrypt it by yourself! The only method of recovering files is to purchase an unique private key. Only we can give you this key and only we can recover your files.

To be sure we have the decryptor and it works you can send an email: and decrypt one file for free. But this file should be of not valuable!

Do you really want to restore your files?•write to email:

•or jabber:

Attention!•Do not rename encrypted files.

•Do not try to decrypt your data using third party software, it may cause permanent data loss.

•Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.




What can you do to avoid being a ransomware victim?

As dangerous as ransomware is, simply being aware and staying updated with the latest ransomware trends can go a long way in securing your data and systems. Here are helpful tips on how you can defend yourself from a likely attack.

Scrutinize emails & its attachments before opening them

Be wary of emails from unverified sources. You can check by communicating directly with the purported sender to confirm if they sent the messages. To check its validity, you can use SecneurX Sandbox to verify the sanity of the email.

Avoid clicking embedded links found in unverified emails

Such social engineering tricks can lead to the download of ransomware. Additionally, be wary of sites that prompt you to enter a CAPTCHA code as this could be linked to a ransomware attack. To check its validity, you can use services like SecneurX Sandbox to verify the reputation of the site.

Back up your important files

While prevention is always better than the cure, having a backup of important files can at least lessen the potential damage done by a ransomware attack. While being locked out of your own system is always a bad thing, at least it's not a total disaster since you can always retrieve your important files. The 3-2-1 backup rule applies here—three backup copies of your data on two different media, and one of those copies in a separate location.

Regularly update software, programs, applications

Updating them to the latest versions can provide an added layer of protection against online threats as some ransomware arrive via vulnerability exploits.

Use a layered protection suite

Doing so can detect threats before they enter your network. Security solutions like SecneurX ATP can block Infectious files (like executables (.exe, .run, etc.), archives (ZIP, RAR, etc.), Microsoft Office and PDF documents, JavaScript, and so on) by scanning them at the point of entry of the organizations (File uploads, USB file transfers etc)
