    It has been revealed that the virus is being distributed as a single binary file named BitKangoroo.exe, bitkangoroo.exe or IEAgent.exe. Based on this information we can conclude that the hackers have made virus copies that pose as Internet Explorer program files, executables or installers.

    BitKangoroo Virus – Ransomware Features

    Once the BitKangoroo ransomware virus has successfully infiltrated the host it places itself in the following system location: %UserProfile%\AppData\Roaming\IEAgent.exe. This malware employs a dangerous encryption engine with the AES-256 cipher which is able to process a large quantity of sensitive user files. Like other similar threats it uses a built-in list that can be modified by the hackers according to their predefined targets. In its current form the BitKangoroo ransomware virus is able to encrypt data such as: documents, photos, music, videos, archives, configuration files, databases and etc.

    All affected files are renamed with the .bitkangoroo extension. Once this is done the virus enforces a lockscreen that effectively blocks all ordinary computer interaction. It reads the following message:

    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!


    From this message we can conclude the following facts about the BitKangoroo ransomware virus:

    • The ransomware message appears to copy templates used by previously known viruses. This means that the criminal operators may have taken code from other viruses and implemented it in the BitKangoroo ransomware virus.
    • The requested ransomware sum is one Bitcoin. At today’s conversion rate this equals to 1744 US Dollars.
    • Only a Bitcoin address is supplied. The victims can press a button to write an email to the hackers but it is not displayed in plaintext. The lack of a dedicated payment gateway may mean that a future version of the BitKangoroo ransomware virus can add various hacker “support” options.
    • A time limit is enforced on the victims to further extort them.

    NOTE: At the moment the BitKangoroo ransomware virus is currently under development. The security researchers stated that the captured samples encrypt the files located on the users Desktop. In addition if the victims enter a non-working code then all encrypted files are deleted.
