What is WannaDie ransomware? And how does it apply its attack?

WannaDie ransomware is a file-encrypting malware designed to take a victim’s files hostage with the use of an encryption algorithm. Security experts dubbed this ransomware as a Russian WannaCry imposter imitating the notorious WannaCry ransomware. WannaDie was first discovered on November 17, 2017 and despite its best efforts to copy the WannaCry ransomware, it’s really a far cry from the infamous threat as WannaDie is only created using the open source platform, Hidden Tear.

This ransomware spreads through an obfuscated file named wndi.ee which is distributed using malicious spam emails. Once this corrupted payload is dropped into the system, it immediately installs WannaDie ransomware and scans the computer to look for files to encrypt. The files that may be encrypted in the attack may include the following file formats:

.1cd, .csv, .dat, .doc, .docb, .docm, .docx, .dot, .dotm, .dotx, .dt, .DT, .dt, .ged, .hbk, .hbk, .htm, .html, .key, .keychain, .md, .pps, .ppt, .pptx, .sdf, .tar, .tax2014, .tax2015, .txt, .vcf, .xlc, .xlm, .xls, .xlsb, .xlsm, .xlsx, .xlt, .xltm, .xltx, .xlw, .xml.

As it starts data encryption, it appends the wndie extension on the affected files using a combination of AES and SHA 256 encryption algorithms making its encryption strong. After the completion of data encryption, it opens a program window labeled “Wana die decrypt0r” as seen above that contains the ransom note written in Russian. The following context is the ransom note translated from Russian to English:

“Files are encrypted, what should I do?

WHAT HAPPENED WITH MY COMPUTER?

Your important files are encrypted.

Many of your documents, photos, videos, databases and other files are no longer available because they have been encrypted. Perhaps you are busy searching for a way to restore your files but do not waste your time. No one can recover your files without our decryption service.

CAN I RESTORE FILES?

Of course, we guarantee that you will be able to safely and easily restore all your files. But we do not have much time.

You can decrypt some of your files for free. Try clicking Decrypt.

But if you want to decrypt all your files, you need to pay.

Every minute we will destroy one file you need to speed up the process (payment-decryption).

You only have 3 days to send the payment. After that, the price will be doubled.

In addition, if you do not pay within 7 days, you will not be able to restore the files permanently.

We will have free events for users who are so poor that they will not be able to pay for 6 days.

How does WannaDie ransomware distribute its malicious payload?

As stated above, WannaDie ransomware spreads as an obfuscated file named wndie.exe which is distributed using spam emails.
