A very unique ransomware infection has been detected by malware researchers. The virus also dubbed RanRan encrypts files on the computers it infects, just like most ransomware viruses out there do. However, this virus is more than that – it is also politically motivated malware that aims to get the victim to publicly admit he or she is hacked by creating a subdomain and agree with political terms. These terms are against the leader of Saudi Arabia, King Salman bin Abdulaziz Al Saud. Despite this, the virus has also been detected to infect in the Philippines, besides Saudi Arabia, which means it may further spread onto multiple different locations. In case your system has been infected by RanRan ransomware using the .zXz file extension, we advise you to read the following article.

RanRan Ransomware – How Does It Infect
For the infection of this virus, the cyber-criminals behind it may have used malicious files that are uploaded on spammed e-mail messages. These messages are sent to a pre-programmed list of e-mail addresses of potential victims. The e-mails may contain different information, like the name of your account and other data to increase legitimacy. They may also pretend to be different types, for example an e-mail pretending to be suspicious activity on the PayPal account of the victim, provided there is one.
Once a misled victim opens the malicious file attachment, this ransomware infection checks for a specific mutex and if this mutex, also reported as Services 1.0 is present, the virus will stop the infection.
RanRan .zXz Virus – Further Analysis
Once an infection by RanRan ransomware is commenced, the virus dropps a file, named services.exe in the C:\ (System Drive) folder. Once this file has been dropped onto the victim PC, the virus reportedly modifies the Run and RunOnce registry keys to run the services.exe file on system boot. The sub-keys are the following:
After this has been done, the virus creates multiple different files on the computer and runs the encryption.
RanRan .zXz Virus – Encryption Process
For the encryption of the files, the RanRan ransomware infection looks for multiple types of files on the computers it has infected. Most of those files are usually often used and important documents and other content:
→ .mdf .ldf .edb .pst .ost .doc .docx .pdf .xls .xlsx .ppt .pps .pptx .ppsx .accdb .mdb .zip .rar .txt .jpg .bad .epf .bdp .efp .vsd .mpp .xlt .cmd .lic .me .xlsm .war .bdr .stm .sdb .psd .eml .vdw .vdx .tar .csv .max .png .ai .dwg .dxf .7z .c .cpp .bak .ese .ashx .asmx .soap .svc .bkf .issue .sql .fmb .olb .java .webm .mkv .flv .dbf .mtb .asp .aspx .sln .cs .jar .bmp .iso .resx .exe .tar .dat .rtf .img .gz .vmdk .log .ace .kdbx .rdp .psc .bat .cfg .rmvb .3gp .swf .ipdb .db .cmsc .kmz .edx
But the virus does not just get to the encryption of the files. Before this happens, it stops processes of Databases in order to ensure successful encryption. The processes which this ransomware ends are the following:
→ MSSQLSERVER SQLWriter MSSQL$CONTOSO1 SQLServerAgent MSSQL$SQLEXPRESS Microsoft Exchange Information Store OracleASMService+ASM OracleCSService OracleServiceORCL OracleOraDb10g_home1TNSListener usermanager outlook exchange sql
The encryption of the .zXz ransomware is very innovative, but not undefeated. The ransomware uses different encryption procedure for files with different file sizes. For example, if it encrypts files up to 5 MB it will use one set of encryption keys which it generates. But if it encrypts files more than 3 GB, it will proceed with a completely different decryption key being generated.
After encryption, the RanRan virus adds the .zXz file extension to the files which are rendered no longer able to be opened by it. They may appear like the following:
After the encryption process is complete, the .zXz file virus also drops a ransom note with the following message:
Welcome to my Ransomare!
Cannot you find the files youneed?
Is the content of the files that you have watched not readable?
I want to play a game with you. Let me explain the rules:
Your documents, photos, databases and other important files have been encrypted with strongest encryption and unique key, generated for this computer.
Private decryption key is stored on a secret internet server and nobody can decrypt your files until you pay and obtain the private key.
But, don’t worry!
It is normal because the files names, as well as the data in your files have been encrypted.
Do not: power off computer, run antivirus program, disable internet connection. Failures during key recovery and file decryption may lead to accidental damage on files.
In order to have relationship with us, and pay the ransom; must go the following steps.
1. Launch a subdomain named:
2. Make a txt file named:
“Your email address”
We will text you ASAP.”
Unlike other ransomware viruses, this one extorts users to register to a political website, which means that it is one of the few ransomware viruses with a hacktivist element in them.
Fortunately the virus is decryptable, thanks to Palo Alto malware researchers. Keep reading this article to learn how to properly get your files back for free if you have become a victim of this virus.
