.kroput Files Virus – How Does It Infect?
Probably one of the main methods that is used for infection with the .kroput ransomware is believed to be via malicious e-mail spam messages. These e-mails often tend to get users to download and start a file that is attached to the e-mails themselves. These files are often disguised as important documents of some sort, such as:
- An invoice for a purchase.
- A document for a cancelled order.
- A file that is a report from a closed bank account.
- Some type of debt-related document.
The files that are usually used may either be JavaScript (.js) files or Microsoft Word and Adobe Reader documents with malicious macros embedded in them. Either way, the files are often uploaded in an archive and once the user downloads, extracts the file and runs it, infection may immediately commence.
Another method via which infection can commence may be by uploading the virus files of the malware on several different websites that are compromised as well as suspicious sites. On those web locations, crooks may use various different types of methods to disguise the files are legitimate ones. Often criminals use the following files to trick victims into downloading and getting infected with .kroput files virus:
- Fake installers.
- Fake cracks.
- Fraudulent activators for Windows.
- Fake portable versions of programs.
.kroput File Ransomware – What Does It Do
Once an infection occurs with the .kroput files virus, the ransomware may begin to create files on your computer. The files may often reside in the following Windows directories under different, often random names:
- %Temp%
- %AppData%
- %Roaming%
- %Local%
- %LocalLow%
The main malicious file of .kroput files ransomware was detected to have the following identification information:
→ SHA-256:114ccacb7ca57c01f3540611fdf49e68416544da8d8077f5896434a4b71b01dd
Name:updatewin.exe
Size:277.5 KB
In addition to it, since .kroput is a variant of STOP ransomware, the ransom note _readme.txt is also dropped on victimised machines:

In addition to the malicious files created by this ransomware, the .kroput virus may also perform other virus activities as well:
- Create mutexes on the compromised machine.
- Check to see if the virus is dropped on a virtual drive or is running on actual PC.
- Take screenshots on the compromised computer.
- Log the keystrokes you type.
- Obtain information about your location(IP) and language.
Furthermore, the .kroput files ransomware may also perform other unwanted activities on the computers that have been compromised by it. One of them is to allegedly create a randomly named registry string on the victimised machines which has data embeded in it that may automatically run the virus files of .kroput ransomware so that the virus runs automatically each time you boot Windows. The keys that are usually used for this purpose are the Run and RunOnce sub-keys in Windows. They have the following location:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
In addition to this, the .kroput file ransomware could also perform series of other malicious activities on the computers that are infected by it and among them may be to delete the backed up files and shadow copy files on the computers, compromised by it. The outcome of this is for the user to not be able to restore files via Windows Recovery services. To reach its goal, the .kroput files virus may run the following commands as an administrator in Windows Command Prompt:
→ sc stop VVS To encrypt files on the computers that have been infected, .kroput files virus may begin to scan for them, based on their file extensions. The following types of files may be encrypted by the .kroput files virus: → “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.
