What is Blood Jaws ransomware? And how does it implement its attack?
A new crypto-malware has been spotted in the wild named “Blood Jaws ransomware” but unlike other ransomware threats, it is created with a purpose of demonstrating to users how devastating a ransomware attack can be. It is created and released by Virus Express. And since this is an educational ransomware, the files it encrypts can be decrypted for free. However, just like HiddenTear, an open source platform which was also initially released for educational purposes, it could be exploited by cybercriminals in order to create an even more dangerous file-encrypting threat.
Once Blood Jaws ransomware is up and running in the system, it drops two executable files namely, Runme.exe and Bloodjaws.exe. The Runme.exe file is used to execute a series of tasks on the infected device. For one, it adds more malicious files in the system that helps it stay undetected. It also makes alterations in the Windows Registry in order for the crypto-virus to run on every system startup. Right after applying these changes, Blood Jaws ransomware will begin the encryption process and once it’s done, it will display the following ransom note in the screen:
“Your personal files have been encrypted.
All images, videos, music, documents, and executables on this PC have been encrypted by Blood Jaws ransomware.
To decrypt your files, locate and run the Blood Jaws decryption program. It is called ‘bloodjaws.exe’. Decryption is free.
Do not delete the Blood Jaws Decryption program if you want to be able to decrypt your computer.
Uninstall your antiviruses as they may try to uninstall the Blood Jaws Decryption program which is your only way of saving your PC.”
In addition, it also opens another file named “readme.txt” which contains a message that reads:
“Blood Jaws ransomware
Blood Jaws is ransomware!
Run at your own risk. Run ‘runme.exe’ if you really want to kill your PC.
I am not responsible for any damage done.
Tested on Windows 10 (64)
The virus made by Virus Express.
AES 256 Bit Encryption used with the password: [email protected]:”
How does Blood Jaws ransomware spread online?
Blood Jaws ransomware may spread using spam emails so you need to be extra careful in opening emails even though this new ransomware threat is harmless for now. Usually, crooks attach an obfuscated file in emails such as a document with macro scripts. If opened, these macro scripts will be executed and will launch Blood Jaws ransomware into the system.
