What is Stinger ransomware? And how does it implement its attack?

Stinger ransomware is a newly discovered ransomware threat seeking to encrypt files on targeted PCs. This file-encrypting threat utilizes the AES encryption algorithm in locking its targeted files. It was spotted in the middle of March this year by a group of security researchers. According to these researchers, it mainly targets English, German and French-speaking users. Nevertheless, it doesn’t mean it can’t affect other users all over the globe. Researchers also noted that this ransomware contains the following parameters:
Size:39.5 KB
The moment it manages to infect a system, it will immediately create and download several malicious files to help it implement its attack. It also modifies the Windows Registry to achieve persistence. After that, it will encrypt files with the following extensions using the AES cipher.
Each of the encrypted file will have the .Stinger extension, signifying the attack of Stinger ransomware. Victims are then informed about the attack using a ransom note contained in a file named “About .Stinger unlocking instructions.txt” that states:
Hello, friend, Please read the following
Your file has been locked, please do not close the system, or modify the extension name

As you can tell, the ransom note of Stinger ransomware does not provide much information about itself and victims are urged instead to contact the given email address. If you are one of the unfortunate victims of Stinger ransomware, there is no need for you to contact the crooks behind this crypto-malware because one thing’s for sure – the cyber crooks will demand a huge amount of ransom which is totally not worth it as it does not really guarantee that you’ll get your files back. So instead of wasting your money and time with these criminals, it’s better if you prioritize the removal of the threat and then try other alternative ways to recover your encrypted files.
How does Stinger ransomware proliferate?

Restore the previous state of your files using the Shadow Volume copies
Restoring your encrypted files using Windows’ Previous Versions feature will only be effective if Stinger ransomware hasn’t deleted the shadow copies of your files. But still, this is one of the best and free methods there is, so it’s definitely worth a shot.
