And RSA-2048
More versions of the Trick or Treat ransomware may have been released to the Internet and could encrypt users’ files. Be careful while browsing the Web or you might have a jump scare.
Trick or Treat Ransomware – Delivery Methods
Trick or Treat ransomware could be delivered in more than one way. However, the way that is the most widespread is via a payload dropper file which initiates the malicious script for the ransomware. A sample has been spotted by malware researchers and you can preview its analysis, which is available on the VirusTotal service from down below:
The Trick or Treat ransomware might use other ways to deliver the payload file, such as social media and file-sharing sites. Freeware applications found on the Internet could be promoted as helpful but also could hide the malicious script for this virus. Before opening any files after you have downloaded them, you should instead scan them with a security program. Especially if they come from suspicious places, such as emails or links. Also, don’t forget to check the size and signatures of such files for anything that seems out of place. You should read the tips for ransomware prevention provided in our forum.
Trick or Treat Ransomware – Detailed Overview
The Trick or Treat ransomware is a virus, which has been recently discovered. Although the virus might not encrypt, it will still show a ransom note demanding payment to unlock your files. However, Trick or Treat ransomware is not known to encrypt files at the moment, researchers claim. The virus will pop up a window that serves as a ransom note with instructions that is actually a screen that is meant to lock your computer and blocking access to your files.
The Trick or Treat ransomware could be set to make new registry entries in the Windows Registry to achieve a higher level of persistence. Those entries are usually designed in a way that will start the virus automatically with every launch of the Windows Operating System, like in the example given below:
→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”
The ransom message that loads up can be seen right here below:
The ransom note message states the following:
Trick or Treat
Uh Oh! Your Files Have Been Encrypted,
By Trick or Treat Ransomware!
Trick or Treat
Decrypt My File’s!
The ransom sum that is demanded as payment for allegedly restoring access to your computer is unknown. However, you should NOT pay cybercriminals as that may only serve as a motivation for them. Nobody can guarantee you will get your computer back to the way they were. As the virus doesn’t necessarily lock your files themselves but meant to block just the access to them, it is removable. Keep on reading to see how.
Trick or Treat Ransomware – Encryption Process
There is no official list with file extensions that the Trick or Treat ransomware seeks to encrypt and the article will be duly updated if there are changes regarding that. Encryption doesn’t seem to be present in some variants of the ransomware. The virus might still be in-development and the encryption feature might be added in the near future.
Update November 2017! The encryption which might be implemented in the near future (or already has on versions not found by researchers) could be AES-256 and RSA-2048 combined. That is if the ransom note is telling the truth about the encryption algorithms.
The Trick or Treat cryptovirus is more than likely to erase the Shadow Volume Copies from the Windows Operating System by executing the following command:
→vssadmin.exe delete shadows /all /Quiet
If the above-stated command is inputted into the command prompt of the Windows operating system, that will make the encryption process more effective, as one of the main ways for file recovery will be gone. Continue to read to find out what methods you can try out to potentially restore some of your files.

- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by Trick or Treat there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove Trick or Treat
