.choda File Virus (Jigsaw) – Spread
Jigsaw ransomware could infect computers using different methods for spreading that infection. Spam e-mails could be spreading its payload dropper. Those types of emails will try to convince you that something important is attached as a file to that e-mail. In actuality, the attachment will look like a legitimate document or one that is archived, but it is a file containing a malicious script. If you open that file, it will launch the payload for the ransomware. You can preview the analysis of one such file on the VirusTotal service:
As you can see above, the payload file is called 초다 랜섬웨어.exe.
Jigsaw ransomware might be using other methods for spreading, like putting the payload file dropper via social media and file-sharing sites. Freeware applications which roam the Internet could be presented as useful but also could hide the malicious files of this virus. Refrain from opening files after you download them, especially if they come from unverified sources, such as links and e-mails. First, you should scan these files with a security tool, and also make sure to check their sizes and signatures for anything that seems unusual. You should read the ransomware preventing tips topic in the forum.
.choda File Virus (Jigsaw) – In Detail
The Jigsaw ransomware ransomware virus keeps on appearing on the radar of malware researchers. This variant displays a text in the Korean language and not themed around the Jigsaw character from the movie series “SAW” as its original Jigsaw Ransomware variant did.
When the Jigsaw virus is executed, it will modify an existing entry in the Windows Registry or create a new one to achieve persistence. That registry entry makes the malware to automatically execute with each boot of the Windows operating system. Afterward, your files will get encrypted, and receive the same extension.
Next, a window will pop-up on your screen that shows the Jigsaw character and text being typed out with green letters. That text is the ransom message with information and instructions for payment.
The text of the ransom note reads:
주확톤 당진희 침퓨터가 지짐각하계 존쟝되었줄끄띠토
당신의 소중한 파일몰온 조다 랜섬웨어에 의해 감염되었습니대

The note roughly interpreted with machine translation in English says:
Dangjin of the State of the week, we will be in the summer John Jean!
Your precious files have been infected by the Mall of Jorda Ransomware
Now you can revert the distant files that follow my directives.
All of the files are encrypted and can not be accessed.
This ransomware is based on the Pode encryption method molar.
Therefore, there is no sense in changing the extension drive.
The file extension can not be reversed even if the directive is changed.
Do not close this long sound or turn off the computer, rules.
If this is closed or the computer is shut down, rule is “kite”
I’ll erase the files again.
Please do not use any other company’s extreme luxury pictures except this program.
While other other extreme glamorous prawns, the file can not be reversed.
From now on, things are simple.
Just enter in the space below here, the ultimate security code, and the dramatization will proceed.
Please do your best
The Jigsaw ransomware scares you that it will delete files from your PC every hour until you pay and there is nothing else that you can do to prevent that. But you should NOT under any circumstances pay the ransom as the note is lying to you – the virus is decryptable. Supporting cybercriminals is a bad idea as that will only motivate them to do more criminal acts.
