HSDFSD Ransomware – Update November 2017
HSDFSD Ransomware – Infection
HSDFSD ransomware might spread its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected. You can see the detections of one such payload file uploaded to the VirusTotal service from the below screenshot:
HSDFSD ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the 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 that seems out of the ordinary. You should read the tips for preventing ransomware found in the forum section.
HSDFSD Ransomware – Overview
HSDFSD is a virus that encrypts your files and extorts you to pay a ransom to supposedly recover them. The malware authors haven’t given it a name, but the ransomware is dubbed by malware researchers after the first letters of the mutex it creates. The extortionists want you to pay in Bitcoin for the alleged restoration of your files.
HSDFSD ransomware might make entries in the Windows Registry to achieve persistence, and could 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.
That ransom note message is displayed after the encryption of your files is complete. It is inside an .html file named Wo_sind_meine_Dateien.html and can be viewed from the following screenshot down here:
That note reads the following:
Ihre Dateien wurden verschlüsselt!
Sehr geehrte Damen und Herren,
Wie Sie mit Sicherheit bereits festgestellt haben, wurden alle Ihre Dateien verschlüsselt.
Wie erhalte ich Zugriff auf meine Dateien?
Um Ihre Dateien erfolgreich zu entschlüsseln, benötigen Sie unsere Spezielle Software und den dazugehörigen Decrypt-Key.

Nach erfolgreichem Zahlungseingang erhalten Sie automatisch die Entschlüsselungs-Software sowie den dazugehörigen Decrypt-Key.
Sollten wir innerhalb von 7 Tagen keinen Zahlungseingang feststellen, gehen wir davon aus, dass Sie kein Interesse an der Entschlüsselung Ihrer Dateien haben. In diesem Fall löschen wir den Decrypt-Key unwiderruflich und Ihre Dateien sind für immer verloren.
Ihre Dateien wurden mit einem 256-Bit AES Algorithmus auf Militärqualität verschlüsselt. Wir empfehlen Ihnen keine Zeit mit eigenhändigen Entschlüsselungsversuchen zu verschwenden, dies würde Sie nur unnötig Zeit und weiteres Geld kosten, Ihre Dateien wären aber weiterhin verschlüsselt.
Zusätzlich zur Entschlüsselungs-Software erhalten Sie nach erfolgreicher Zahlung, hinweise wie die Schadsoftware auf Ihre System gelangen konnte und wie Sie sich in Zukunft vor weiteren Übergriffen schützen können!
A rough translation in English would be the following:
Your files have been encrypted!
Dear Sir or Madam,
As you’ve already noticed, all your files have been encrypted.
How do I get access to my files?
To successfully decrypt your files, you need our special software and its decrypt key.
Where can I get the software?
The decryption software can be purchased from us.
The price for the decryption software is 0.12 Bitcoin (about 600 Euro).
Please note that we only accept Bitcoin for the purchase of the software.

The note of the HSDFSD ransomware states that your files are encrypted. You are demanded to pay 0.12 Bitcoin which equates to around 850 US dollars. However, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal acts.
HSDFSD Ransomware – Encryption
What is known for the encryption process of the HSDFSD ransomware is that the cryptovirus places a random extension to all locked files. Furthermore, the encryption algorithm used by the virus is AES with 256 bit ciphers, according to the ransom note at least.
The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The HSDFSD cryptovirus is coded to erase all the Shadow Volume Copies from the Windows Operating System by using the following command:
→cmd /c vssadmin.exe delete shadows /all /quiet & wmic shadowcopy delet
The above-stated command is executed and that makes the encryption process more efficient. That is due to the fact that the command eliminates one of the prominent ways to restore your data. If your computer device was infected with this ransomware and your files are locked, keep on reading to find out how you could potentially recover your files.
