Kangaroo ransomware

The first Kangaroo ransomware version includes an advanced operation module

This virtual parasite aims to have a bit more complex module than others of its kind. Once the malware accesses the operating system via hacked RDP and appears on the machine, it displays a lock screen that prevents numerous users from using their computers until they transfer the demanded price or eliminate the cyber threat.[3] Kangaroo ransomware virus is able to complete such a task by disabling Explorer processes and deactivating the Windows Task Manager.

Kangaroo ransomware virus mimics a legal notice and displays it as a ransom note before the infected users aim to log in to their computer systems. This way the cybercriminals are assured that the victims will spot the message before taking any further actions. In order to succeed in this process, the malware adds the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon “LegalNoticeText” registry key. Afterward, the ransomware virus initiates the encryption process by using the AES key to lock up all files and documents that are found on the infected device. 

Kangaroo virus adds the .crypted_file appendix to each filename of the encrypted components. Afterward, the malware displays the ransom note named (filename).Instructions_Data_Recovery.txt. Continuously, the parasite adds a lock screen that displays a fake warning about a critical system problem and data encryption where the [email protected]  cybercriminals’ contact email is added as a way to perform communication between the crooks and the victims.

Ransomware infections are distributed via hacked RDPs and email spam

According to NoVirus.uk specialists,[4] a lot of ransomware versions are downloaded directly to your computer via Remote Desktop applications. Once cybercriminals hack the system, they locate your IP identification and encryption codes. Likewise, they infiltrate the system. Later on, the malware initiates the encryption process. 

Mostly, the hackers search for RDPs that include weak protection or none at all. So, it is very important that you secure your RDP with a strong and complex password that includes letters, numbers, and symbols. This way you decrease the chances of getting your RDP hacked by malicious actors.

Continuously, another popular method through which ransomware infections are delivered is known to be email spam. By using this technique, the cybercriminals drop legitimate-looking email messages to random users and attach the infectious payload to the email message itself in the form of an executable, PDF or word document.

The crooks often pretend to be from some reliable companies, healthcare, banking, shipping firms. If you ever receive an email message that you were not waiting for, you should not rush to open it as there might be malicious content planted inside it (in a form of a hyperlink) or attached to it. Scan all the attached files with an antimalware product before opening them just to make sure that they are not infected with malware.
