BitKangoroo Ransomware – Update

Update! A decrypter is now available for the BitKangoroo ransomware! The tool was created by the malware researcher Michael Gillespie and can be downloaded from the following link, wrapped inside a .zip archive: BitKangoroo Decrypter.

BitKangoroo Ransomware – Delivery

BitKangoroo 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. Samples have been spotted by malware researchers and you can preview one of them sent for analysis on the VirusTotal service right here:

The BitKangoroo ransomware might be using other ways to deliver the payload file, such as social media and file-sharing sites. Freeware applications found on the Web 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 ransomware prevention tips given in the forum section.

BitKangoroo Ransomware – Overview

The BitKangoroo ransomware is a cryptovirus, which has been recently discovered by malware researchers. They believe that the ransomware is still in-development and encrypts only files found on your Desktop. When the BitKangoroo ransomware encrypts your files, it will put the .bitkangoroo extension to every file and show a window that serves as a ransom note with instructions.

In the future, the BitKangoroo 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 provided below:


The ransom message will be placed inside a window with a timer. This is how it looks:

The following message about the ransom payment is in that window:

Your desktop file have been encrypted.
To unlock them, pay 1 BTC to the following address…
Every hour you wait to pay, I’ll delete one of them.
Bitcoin address:
Time remaining: 40:13
Decryption key:
Decrypt my files
Once you have paid, send the following email adding your bitcoin address:
Click me to write the email!

Upon clicking the button “Decrypt my files” from that window, the following warning message pops up in a smaller window:

Are you sure the decryption key is correct? You have ONE attempt to insert the key! If it isn’t correct, all your files will be deleted!

To add to that, the following e-mail template will be loaded if you click the last line in the ransom payment instructions window, labeled as “Click me to write the email!”:

Take note that you have a 1-hour timer that resets after it deletes a file, and that it’s almost impossible to get Bitcoin for such a short amount of time. That should be more than enough for you to not comply with anything that is said inside the ransom note. Besides, a decrypter utility might be released soon if the code of the virus has flaws.

BitKangoroo Ransomware – Encryption

There is no official list with file extensions that the BitKangoroo ransomware seeks to encrypt and the article will be updated if such a list is found. However, all files which get encrypted will receive the .bitkangoroo extension appended to them. The encryption algorithm which is used for the virus is AES 256-bit.

The BitKangoroo 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. Keep reading to find out what methods you can try out to potentially restore some of your data.
