Schwerer Ransomware – Infection Spread

The Schwerer ransomware could spread its infection by using different methods. The payload file that initiates the malicious script for this ransomware that in turn infects your computer system is seen on the Web. Malware researchers have found a sample of the virus. You can see the sample and the detections of multiple security program vendors on the VirusTotal service by checking out the snapshot right here below:

Schwerer ransomware could also distribute its payload file on social media and file-sharing networks. Freeware which is found online could be presented as helpful but at the same time could be hiding the malicious script for the cryptovirus. Don’t open files immediately after downloading them, before you have checked them with a security tool. That goes especially if they come from dubious sources such as links and e-mails. Don’t forget to check the size and signatures of these files for anything that seems out of the ordinary. You should read the ransomware preventing tips thread in the forum.

Schwerer Ransomware – Technical Description

Schwerer ransomware is a virus that is written with the AutoIt language. AutoIt is a freeware BASIC-like scripting language. The ransomware is made to encrypt files on a computer machine and ask for a ransom.

The Schwerer ransomware could make entries in the Windows Registry to achieve persistence, launch or repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each launch of the Windows Operating System. The following registry entry is entered by the virus:

→”HKCU\Software\Other\Schwerer” ,”complete” , “REG_SZ”

Whenever the encryption process is fully complete, a ransom note will be displayed in a window box. The note is written in the English language. Inside the window, you will find instructions on what to do for the restoration of your files.

You can preview the ransom note message here:

The ransom note reads the following:

All your computer file were encrypted with AES, only we can restore your files.
How to restore files :
Files encrypted : 2821
1. Send email to 897698@mail2tor.com containing your personal identifier (it is below)
2. We will send you a Bitcoin address, you must send 150€ to it within 3 days.
IF YOU DO NOT UNDERSTAND BITCOIN EMAIL WILL CONTAIN INFORMATIONS
3. Once full amount is sent you email us again. (make sure to contain key)
A. We will send you key and you will paste into textbox below, that will restore files.
Your Identifier: 14df8b3376dd29b731f2c7ec8f610df8b33764a608
Restore key:
Restore files

From the ransom note of the Schwerer virus, we can see that the TOR network is used for the contact e-mail left by the cybercriminal. You should NOT pay, nor contact the criminal. The demanded ransom sum is precisely 150 Euros. If you pay, no guarantee exists in the world that you will recover your files back to normal. Moreover, giving money to crooks is very likely to motivate them to keep making more ransomware viruses or do other criminal activities.

Schwerer Ransomware – Encryption Process

Schwerer ransomware seeks to encrypt lots of files with different file extensions. Currently, the following list with file extensions is believed to be the main target for the encryption process of this ransomware:

→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip

Those are the most commonly used files by most Windows users. Every file that gets locked will be encrypted with the AES algorithm or at least that is what is stated inside the ransom note.

The Schwerer cryptovirus is quite possible to delete the Shadow Volume Copies from the Windows operating system by utilizing the following command:

→vssadmin.exe delete shadows /all /Quiet

If the command is indeed executed, the encryption process will become more viable that way, as one of the ways for decrypting your files will be gone. Continue reading and see what kinds of ways you can try out to potentially restore some of your files.
