Kangaroo Ransomware – Delivery

The Kangaroo ransomware can infiltrate your computer machine in some ways. The payload file could be spreading through spam e-mails. Spam mail is made to sound urgent and try to trick you into opening its attached file. If you rush to see what the letter is all about and seek some resolution on the matter that is presented, you might open the file. Malicious content found inside the file will encrypt your computer machine. The payload file can be a Trojan horse hidden inside an executable. You can see an example of such a detection on the VirusTotal website:


Kangaroo ransomware might infect your device using more methods. The developers of the ransomware could deliver the files through social media networks and file-sharing websites. The malicious file could be hosted on one such platform with the aim of infecting more PCs. Refrain from opening unknown links and files from dubious sources. Before you think of opening files, scan them with a security application and check their signature and size. You should read the ransomware prevention tips in the corresponding forum topic.

Kangaroo Ransomware – Description

Kangaroo is now the latest malware strain related to the Apocalypse ransomware and Esmeralda ransomware.

It will encrypt your files and then place the extension .crypted_file to every one of them. Instructions with the demands will be written in a text file and also launched as a ransom message on a screen after the encryption process is complete.

After the Kangaroo ransomware executes its payload, it can create entries inside the Windows Registry for achieving persistence. Those registry entries are created to make the virus start automatically with every boot of the Windows operating system. Then, your files become encrypted, and the ransom note displays on your desktop screen. The ransom message is inside a file called Instructions_Data_Recovery.txt.

You can see the ransom message from the below snapshot:


The message reads the following:

Windows has encountered a critical problem and needs your immediate action to recover your data. The system access is locked, and all the data have been encrypted to avoid the information be published or misused. You will not be able to access to your files and ignoring this message may cause the total loss of data. We are sorry for the inconvenience.

You have to contact the email below along with your Personal Identification ID to restore the data of your system.

Your Personal Identification ID: 2F5BD40FDE

Email: [email protected]

You will have to order the Unlock-Password and the Kangaroo Decryption Software. All the instructions will be sent to you by email.

There appears to be another version using the [email protected] email address. This could somehow be related to the Philadelphia ransomware as it seems that is another bad joke targeted at the highly respected malware researcher Fabian Wosar.


No further instructions are given unless you contact the email address and write to the cybercriminals. Do NOT contact the criminals or pay, in any case. No one can guarantee you that by paying you will get your data restored. Adding to that the cybercriminals will probably invest the money in other ransomware viruses or more criminal activities.

The Kangaroo ransomware encrypts files while appending the .crypted_file extension to them. The encryption process uses the AES encryption algorithm according to malware researchers.

The Kangaroo cryptovirus is highly likely to erase the Shadow Volume Copies from the Windows operating system by using the following command:

→vssadmin.exe delete shadows /all /Quiet

Read below to see what methods you can try to possibly restore your data, at least partially.
