What is EbolaRnsmwr ransomware? And how does it execute its attack?

EbolaRnsmwr ransomware was first discovered in the cyber security community on October 13, 2018, and was developed based on the open-source platform, HiddenTear. At the time of writing, its developers remain unknown and it seems that they are still working on this crypto-malware since security experts discovered that this crypto-malware is missing a few features in its attack. Although this ransomware is still a work in progress, it doesn’t mean that it can’t encrypt files – it definitely can and it uses “.101” extension in marking its encrypted files. The strange thing about this ransomware is that instead of demanding ransom in the form of Bitcoin payments, it demands an Amazon Gift card.

EbolaRnsmwr Ransomware

Once it infects a computer, it downloads and creates malicious components that help it in executing its attack. It also employs a data gathering module used to obtain information about the user and the system. The data obtained is then used for the next module called stealth protection which protects the malware and prevents any programs like AV programs from interfering with the attack. Moreover, it also makes changes in the Windows Registry which allows it to make it’s persistent. Following system modifications, it starts encrypting its targeted files using AES cryptography. After the encryption, it adds the .101 extension to every encrypted file. The moment it finishes encrypting files, it changes the desktop wallpaper with an image that contains the following message:

It also opens a program window as well as a file named “READ_ME.txt” that contains similar content that states:
“Q: What happened to my Files?
A: Your Files for encrypted, which means you can’t use them anymore.
Q: Can I recover my Files?
A: Yes, you can. Follow the Instructions!
Q: Do I have to Pay?
A: Yes, you have. We only accept Amazon Giftcards.!
Q: How did I got infected with this?
A: You are prob. very stupid and you tried to download something which is a pirated program.”

As mentioned, the cybercriminals behind EbolaRnsmwr ransomware demand Amazon Gift cards instead of Bitcoin payments but whatever its demands are, giving in to these demands is a no go since there really is no guarantee that these crooks will give you the decryption software, and besides since it’s still new, you can easily recover your affected files using other methods.
