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 Amazon Gift card.
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 its 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:
“YOUR FILE HAVE BEEN ENCRYPTED THIS MEANS YOU
CAN’T USE THEM ANYMORE.
IF YOU WANT YOUR FILES BACK, YOU HAVE TO PAY!
It also opens a program window as well as a file named “READ_ME.txt” that contains similar content that states:
“Q:What happedned to my Files?
A:Your Files for encrypted, what means you can’t use them anymore.
Q: Can I recover my Files?
A:Yes, you can. Follow the Instructons!
Q:Do I have to Pay?
A:Yes, you have. We only accept Amazon Giftcards.!
Q:How 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 cyber criminals behind EbolaRnsmwr ransomware demands Amazon Gift card 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.
How does EbolaRnsmwr ransomware spread online?
EbolaRnsmwr ransomware spreads using several distribution techniques although it mostly uses malicious spam email campaigns. Cyber crooks tend to disguise malware-laden emails to make them look like they are legitimate emails. However, don’t be fooled as they’re actually sent by cyber criminals. This is why you have to be careful in opening emails even though it may look like a harmless email. You must not take any chances and double check the email before you click any link or download the attachment.
