4rw5w Ransomware – Infection

4rw5w ransomware is currently in a stasis period, but in the future it might spread its infection via various ways. A payload dropper which initiates the malicious script for this ransomware could be spread around the world. If that file lands on your computer system and you somehow execute it – your computer system will become infected. Malware researchers have found a sample of the ransomware and you can see its detections on the VirusTotal service right here:

4rw5w ransomware might begin distributing its payload file on social media and file-sharing services. Freeware located on the Web can be presented as useful and also could hide the malicious script for this cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything suspicious. You should read the tips for preventing ransomware given in our forums.

4rw5w Ransomware – Overview

4rw5w is a crypting virus which encrypts your files and asks you to pay a ransom to get them recovered. Another name by which the ransomware goes by is 4rw5wDecryptor. A few similarities with the WannaCry virus have been spotted in this ransomware regarding its file names, title name and the embedded killswitch in the code of the ransomware. Here is a list of files associated with the 4rw5w ransomware:

  • .4rncry4w
  • 3a.4rnkey
  • 5d.4rnkey
  • t6.4rnkey

4rw5w ransomware could make entries in the Windows Registry to achieve persistence, and probably 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.

The note is written in English, but has an option for translation in other languages. You can view the ransom message that loads after the completion of the encryption process below:

That ransom message reads the following:

we have encrypted your files with 4rw5w crypt virus !
Your important files : photos, videos, documents, etc, were encrypt with our 4rw5w crypt virus.
The only way to get your files back is to pay us 30$ in Bitcoins. Otherwise, your files will be lost.
Caution: Removing of 4rw5w crypt virus will not restore access to your encrypted files.

Bitcoin Adress to buy the decryption key : 16K81jbUkCcUbwjtmW7Lvywp3CJcg2HKoG
Encrypted Files: 0
Decrypted Files: 0

The ransomware demands 30 US dollars as payment for the ransom. However, you should NOT under any circumstances pay the ransom. Your files may not get restored, and nobody could give you any real guarantee for that. Furthermore, giving money to cybercriminals will likely motivate them to create more ransomware or do other criminal activities.

4rw5w Ransomware – Encryption

The 4rw5w Ransomware encrypts files which have the following extensions:

→.avi, .dll, .doc, .docx, .dot, .dotm, .exe, .jpg, .lnk, .mp3, .mp4, .nef, .odt, .pdf, .pif, .png, .png, .rar, .txt, .url, .wav, .zip

It encrypts them with AES and after that it encrypts that key with the Data Encryption Standard (DES), which is a symmetric encryption algorithm. The extensions given above are around 22 in number, but are also one of the most commonly used ones by each user of Windows. All of the files that get encrypted will receive the same extension appended to them, and that is the .4rwcry4w extension.

The 4rw5w cryptovirus might be tweaked 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

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your files. If your computer is infected with this ransomware and your files are encrypted, read on to find out how you could potentially recover them.
