A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample.

Yami Cat ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them.

Yami Cat Ransomware – Detailed Description
Yami Cat is a virus that supposedly encrypts your files and shows a window with instructions on the screen of your computer system. The extortionists want you to pay a ransom for the alleged restoration of your files and restoration of your computer system back to normal.
Yami Cat ransomware makes entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment (such as locking your computer screen). Such entries are typically designed in a way to launch the virus automatically with each start of the Windows operating system.
After the “encryption” process of the Yami Cat virus completes, a ransom message will be displayed on your computer screen. You can see its contents from the following screenshot given right down here:
The ransom note states the following:
Yami cat just encrypted you
Paypal: www.paypal.com/hentaicheat Send 40 dollars
www.paypal.com/hentaicheatDecrypt my files!
Yami cat just encrypted ur files!
ur fucked xd
now u need to pay
Paypal:
paypal.com/hentaicheat
you can’t decrypt ur files without our decrypotemail : yamistinks@gmail.com
email 2 : mizukidev@waifu.clubPay inf
In case you click on the “Decrypt my files!” button, you will see the malware popping up an error notification message:
The above message states:
yami ransomware cat
Bitch u didn’t paid yet. As punishment we will delete 10 files!
The note of the Yami Cat ransomware states that your files are encrypted. You are demanded to pay 40 US dollars as a ransom sum. However, you should NOT under any circumstances pay any ransom. Your files may not get recovered, and nobody could give you a guarantee for that. Moreover, giving money to cybercriminals will most likely motivate them to create more ransomware viruses or commit different criminal acts.
Yami Cat Ransomware – Encryption Process
The encryption process of the Yami Cat ransomware is not known to work at the time of writing of this article. That might change in the future, as the ransomware might be in a developmental phase and implement the encryption feature at a later point in time.
It is currently unknown if any version of this ransomware actually encrypts files. That feature might be implemented in the future, especially if the malware is still under development. Currently there is no information regarding which types of files might get encrypted if such a feature was present in the malicious application. If information about the file extensions which might get encrypted in the future is found, this article will get duly updated.
The files which are used the most by users that would probably get encrypted will probably be from the following categories:
- Audio files
- Video files
- Document files
- Image files
- Backup files
- Banking credentials, etc
The Yami Cat cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:
→vssadmin.exe delete shadows /all /Quiet
In case the above-stated command is executed that will make it harder to restore your computer back to its state before becoming infected with the threat. In the future that would also help make the encryption process more viable. That is due to the fact that the command eliminates one of the prominent ways to restore your data as well. If your computer system was infected with this ransomware and you wish to find out how you could potentially restore your system back to normal, continue reading below.
