Comrade Circle Ransomware – Spreading Technique
For it to be successful whist infecting user PCs’ Comrade Circle may use the conventional tested spreading methods most ransomware viruses tend to use – massive spam of phishing e-mails. For those uninformed, phishing e-mails tend to resemble legitimate e-mail addresses to get users to click on them. Example is the below-mentioned fake LinkedIn invitation containing a malicious web link.
Once the malicious web link or in some cases e-mail attachment, is opened it may cause the infection via an exploit kit, such as the Rig EK, for example. Such kits are very expensive because they locate weaknesses and bugs in Windows only to exploit them and infect the victim’s computer.
However, this may not be the only method of distribution Comrade Circle may use – the virus may also replicate via online file sharing services and software, like dropbox and social media as well. It may also be disguised as fake Adobe Flash Player update or a fake setup of a program that may be uploaded on a shady websites which displays results based on what you “googled” for (download free torrent of someting, etc.).
Comrade Circle Ransomware – More Information About It
As soon as Comrade Circle has been installed on your computer, the malware may immediately begin to modify it. For starters, one or more files may be dropped under different names in the following Windows folders;
- %Common%
- %Roaming%
- %Temp%
- %AppData%
- %System32%
- %UserProfile%
As soon as this is completed the Comrade Circle ransomware has to set up it’s auto launch. This can happen in two ways. One is do drop the file-encryption module directly on the %Startup% folder of Windows which is usually located in:
The other technique which may be used by Comrade Circle ransomware may be to add custom registry entries for the malicious executable that encrypts files. The usual targeted registry entries are the following:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce”
After this has been performed and the encrypter of Comrade Circle ransomware runs, the following files may be encrypted and no longer openable, unless a decryption key is used to unlock them:
→“PNG .PSD .PSPIMAGE .TGA .THM .TIF .TIFF .YUV .AI .EPS .PS .SVG .INDD .PCT .PDF .XLR .XLS .XLSX .ACCDB .DB .DBF .MDB .PDB .SQL .APK .APP .BAT .CGI .COM .EXE .GADGET .JAR .PIF .WSF .DEM .GAM .NES .ROM .SAV CAD Files .DWG .DXF GIS Files .GPX .KML .KMZ .ASP .ASPX .CER .CFM .CSR .CSS .HTM .HTML .JS .JSP .PHP .RSS .XHTML.

The strategy of the cyber-criminals is very clear when it comes to motivating users that have been affected by it. They not only claim that they will give profits to the poor but they also directly advertise their RaaS (ransomware as a service) scheme openly to the ransomware’s victims. This is a very unique strategy and it may actually be successful for them in the future. This is due to the fact that most victims may become cyber-criminals themselves out of desperation and begin to cause infections in multiple different distribution methods, even targeted attack. However, malware researchers strongly advise against following the demands in the ransom note, primarily because any cooperation with cyber-criminals is considered to be illegal and punishable by law. Also, it is no guarantee you will profit and that you will make any money by spreading the malware further and the cyber-criminals may not keep their word at all.
Not only this, but once a ransom is paid, the crooks have even developed a mechanism to keep the infected computer safe from further infections by giving the victim an icon of Stalin that will prevent re-infection by the Comrade Circle cyber-threat(at least according to the ransom note).
