Jolly Roger Virus – Distribution

Jolly Roger ransomware could distribute its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your PC will become infected. You can see the detections of such a file on the VirusTotal service right here:

Jolly Roger ransomware might also distribute its payload file on social media and file-sharing services. You should always scan files you download with a security program. The ransomware connects to a C2 (Command&Control) server to download files and might give remote access to the cybercriminals, allowing them to spread the virus further. You should read the ransomware preventing tips given in our forum.

Jolly Roger Virus – Overview

Jolly Roger is a virus that could encrypt your files and extort you to pay a ransom to get them back to normal. Malware researchers have discovered that it is a variant of the EDA2 open-source project.

Jolly Roger ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.

Your Desktop Background will be changed to the following picture:

That picture is named wall.jpg and it says the following:

Read Instructions.rtf

See the ransom note that is placed on your Desktop after the encryption process completes:

That ransom note is in a file called Instructions.rtf and reads the following:

+We are the only ones in the world that can provide your files for you!
+When your PC was hacked, the files were encrypted and sent to a server we control!
+You must send 0.1 BTC about 250 USD to
+Within 1 week from now to retrieve your files and prevent them from being leaked!
+When you have sent payment, please send email to with:
1) Date Transaction
2) PC’s Name
3) Email to send you the KEY
+Once we confirm the transaction, we’ll send email with the key and the process to decrypt all your files
+Check your spam looking for Email Subject: AES Key lucky guy!
+You can purchase BITCOINS from many exchanges such as:
or google for your country
*We are business people and treat customers well if you follow what we ask
*Remember your email is one-way, so don’t do anything stupid
*And please don’t waste time trying to decrypt with some local service, without the key is impossible, we use AES encryption
Thank you for your cooperation

The background of the virus uses a variation of the pirate flag known as Jolly Roger, similarly to another ransomware – Alma Locker Ransomware. The note of the Jolly Roger ransomware states that your files are encrypted. A ransom of 0.1 Bitcoin is demanded as payment for potentially unlocking your files. However, you should NOT under any circumstances pay any ransom. Your files may not get restored, and nobody could guarantee that. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware viruses or do other criminal activity.

Jolly Roger Virus – Encryption

Jolly Roger ransomware is reported to seek and encrypt files with the following extensions:

→.3df8, .3gp2, .accdb, .adpb, .amxx, .ascx, .ashx, .asmx, .ddcx, .disk, .divx, .djvu, .docm, .docx, .dotm, .dotx, .exe, .exif, .gthr, .gzig, .html, .indd, .itdb, .java, .jfif, .jiff, .jpeg, .locked, .mbox, .mpeg, .potm, .potx, .ppsm, .ppsx, .pptm, .pptx, .rsrc, .shar, .tax2013, .tax2014, .tbz2, .text, .thmx, .upoi, .wave, .wdgt, .wmdb, .wmmp, .xlam, .xlsb, .xlsm, .xlsx, .xltx, .xlwx, .xvid, .zipx

Every single file that gets encrypted will receive the same extension appended to it, which is .locked. The encryption algorithm which is implemented is AES as reported by malware researchers.

The Jolly Roger cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your data. If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your data.
