Ransom:Win32/Threatfin is classified as a ransomware that is usually installed via other malware through a backdoor. Ransom:Win32/Threatfin displays a full-screen message that blocks the desktop and makes it inaccessible. Certain files may also be encrypted. The displayed message contains information about paying a fee so that access to the PC is regained. Security specialists do not recommend paying the ransom since the files may not be decrypted. The most effective measure against ransomware is having all important files backed up on an external device or via a cloud service.
Ransom:Win32/Threatfin Description
Researchers have reported that Ransom:Win32/Threatfin is installed on a computer as a dynamic link library file. The DLL file can be loaded by other malicious threats. It can be found in either directories:
%TEMP% \ie2.dl
%TEMP% \reg.dll
Furthermore, Ransom:Win32/Threatfin can create new registry keys so that it runs every time the PC is started. Here is a short list of added registry entries, as reported by Microsoft:
- In subkey HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Sets value: “IE11”
With data: “regsvr32 “%temp%\ie2.dll”” - In subkey: HKCU\Software\Microsoft\Windows\CurrentVersion\Run
Sets value: “WINUP”
With data: “regsvr32 “%temp%\reg.dll”
or
Once installed on a machine, Ransom:Win32/Threatfin will create some files on the user’s desktop:

HELP_DECRYPT.html
The six listed files can be described as the ransomware’s payload preventing the user from accessing his computer. The message displayed by Ransom:Win32/Threatfin pushes users to pay a certain amount of money, usually through BitCoin, in order to reclaim their computers and decrypt encrypted data.
However, paying the ransom does not necessarily result in data decryption since such threats are solely created to generate revenue for attackers.
Ransom:Win32/Threatfin Variants Similar to CryptoBot
Researchers warn that some variants of Ransom:Win32/Threatfin launch a window named CryptoBot. The displayed window contains information about the actions executed by the threat and a list of the encrypted files.
The CryptoBot file is installed as a text file:
%TEMP% \crypto_bot.log
Files with the following extensions will be encrypted:

After encryption has finished, the attackers will contact a remote host. Researchers at Microsoft reported that the ransomware attempts to connect to 65.49.8.104 at TCP port 443 to send and receive data from a remote server.
To stay secure against ransomware, users should frequently back up all of their valuable files to an external device or in a cloud.

- Do a backup of all of your files, even if they could be damaged. You should back up your data with a cloud backup solution and insure your files against any type of loss, even from the most severe threats.
- Be patient as this could take a while.
Step 1: Boot Your PC In Safe Mode to isolate and remove Ransom:Win32/Threatfin
Step 2: Clean any registries, created by Ransom:Win32/Threatfin on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- 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 Ransom:Win32/Threatfin 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.Step 3: Find files created by Ransom:Win32/Threatfin
For Windows 8, 8.1 and 10.

3: Navigate to the search box in the top-right of your PC’s screen and type “fileextension:” and after which type the file extension. If you are looking for malicious executables, an example may be “fileextension:exe”. After doing that, leave a space and type the file name you believe the malware has created. Here is how it may appear if your file has been found:
N.B. We recommend to wait for the green loading bar in the navination box to fill up in case the PC is looking for the file and hasn’t found it yet.
