- %AppData%
- %Roaming%
- %Temp%
- %Local%
- %LocalLow%
After this has completed, the ransomware virus may modify the registry entries on the compromised computers, more specifically by adding custom value strings. It may attack the Run and RunOnce registry sub-keys and in them add strings that make the malicious executable of ImSorry ransomware run automatically. The sub-keys have the following locations:
→ HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\
After this has been completed, the ransomware infection aims to perform multiple different actions to prevent any data recovery from Windows Backups. One of those is to delete the shadow volume copies possibly by executing a script that enters the following administrative Windows Command Prompt commands:
→ process call create “cmd.exe /c
vssadmin.exe delete shadows /all /quiet
bcdedit.exe /set {default} recoveryenabled no
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures
In addition to those activities, the ImSorry ransomware virus also drops it’s ransom note on the compromised computer. This ransom note is responsible for getting the user closed to the end goal of the cyber-criminals – paying the ransom. The note is in two files, a program and a text file, named Read me for help thanks.txt. When opened, the program displays the following pop-up:

ImSorry Ransomware – Encryption Process
The encryption of the ImSorry ransomware virus is performed In one of the encryption modes that are compatible with the AES encryption algorithm. These modes include 10 passes, 12 passes or 14 passes for the AES-256 cipher. The encryption consists of replacing segments of plaintext data with a ciphertext data. This activity results in the file no longer able to be opened. For the encryption process, the ImSorry ransomware virus targets specific files and is very careful to avoid Windows files that may damage the OS. The targeted files may be of the following file types:
“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.
