Remove KANGAROO virus: how to decrypt KANGAROO encrypted files

Description:

The authors of the once widespread KANGAROO ransomware have coined a new extortion tool that goes by another popular Russian name – Mischa. Whereas these two undoubtedly represent the same family and share some behavioral patterns, the latter is drastically different from its forerunner. The Mischa ransomware is a more ‘classic’ sample, because it encrypts the end user’s personal files rather than corrupting the Master File Table. This somewhat milder impact, which still allows the infected person to actually boot into Windows, doesn’t make the newcomer Trojan any less hazardous, though. It uses a cryptographic algorithm that’s strong enough to prevent data recovery through brute-forcing, which basically means that the victim runs the risk of losing all important files unless they pay up. – PowerPoint PPT presentation

  • The authors of the once widespread KANGAROO
    ransomware have coined a new extortion tool that
    goes by another popular Russian name Mischa.
    Whereas these two undoubtedly represent the same
    family and share some behavioral patterns, the
    latter is drastically different from its
    forerunner. The Mischa ransomware is a more
    classic sample, because it encrypts the end
    users personal files rather than corrupting the
    Master File Table. This somewhat milder impact,
    which still allows the infected person to
    actually boot into Windows, doesnt make the
    newcomer Trojan any less hazardous, though. It
    uses a cryptographic algorithm thats strong
    enough to prevent data recovery through
    brute-forcing, which basically means that the
    victim runs the risk of losing all important
    files unless they pay up.

  • The authors of KANGAROO, a new data-encoding
    trojan sample, appear to have fairly modest
    mercantile appetites as they extort an unusually
    low ransom of 0.1 Bitcoins, which converts to
    about 40 USD. This feature, though, doesnt make
    such an attack incident any less abominable than
    the rest of the crypto malware assaults out
    there. The online criminals trump card in
    defrauding their victims of some savings is a
    rather strong cryptosystem leveraged in the
    course of the compromise.

  • The offending program makes use of a blend of
    AES-256 and RSA-2048 to turn ones personal data
    into an array of inaccessible entities. It
    targets both the files stored locally and those
    residing on mapped network shares as well as
    external media thats currently inserted into the
    infected computer running Windows or Linux. The
    range of file formats at risk isnt very
    plentiful, covering objects with about 40
    different extensions, as opposed to some
    ransomware variants that lock hundreds of types
    of data.

  • Harmful is a barely accurate attribute to
    characterize the effect impaired by ransom
    trojans, because the damage tends to get
    tremendous. The only user that has nothing to
    worry about in the face of these attacks is one
    who doesnt keep any information on their
    computer, which is fiction rather than a
    plausible scenario. Ransomware blocks out ones
    access to data deposited on local drive volumes
    as well as mapped network shares. The latest
    edition of the notorious KANGAROO infection does
    exactly that, appending files with the .LOL!
    extension and creating a document with recovery
    tips named how to get data.txt inside every
    path with encrypted entities. As a result, the
    victim can no longer open files saved in more
    than 130 different formats.

    encrypted files

  • This approach relies on the native Windows backup
    of files on the computer, which is conducted at
    each restore point. There is an important
    condition to this method it works if the System
    Restore feature was toggled on before the
    contamination. Also, if changes were made to a
    file after the most recent restore point, they
    wont be reflected in the recovered file version.
  • Use Previous Versions feature

8
  • The Properties dialog for random files has a tab
    called Previous Versions. Thats where the backed
    up versions are displayed and can be recovered
    from. So right-click on a file, go to Properties,
    hit the above-mentioned tab and select the Copy
    or Restore option, depending on the location you
    would like it recovered to.

  • Apply ShadowExplorer
  • The above process can be automated with a tool
    called ShadowExplorer. It basically does the same
    thing (retrieving Shadow Volume Copies), but in a
    more convenient way. So download and install the
    application, run it and browse to files and
    folders whose previous versions you wish to be
    restored. To get the job done, right-click on any
    of the entries and select the Export feature.
  • Backups

10
  • Out of all the options that arent
    ransom-related, this one is the most optimal. In
    the event you had been backing up your
    information to an external server before the
    ransomware hit your PC, restoring the files
    encrypted by KANGAROO is as simple as logging
    into the respective interface, selecting the
    right files and initiating the restore
    transaction proper. Before you do so, however, be
    sure to completely remove the ransomware from
    your computer.
