What is eCh0raix ransomware? And how does it execute its attack?

eCh0raix Ransomware

eCh0raix ransomware is a newly discovered file-encrypting virus that can cause serious damage to targeted files in a computer. It was found to be targeting QNAP network-attached storage or NAS devices. It was first spotted by Trend Micro and it seems to execute its attack similar to other infamous ransomware threats like Ryuk or LockerGoga ransomware.

This new crypto-virus is written in a programming language known as Go/Golang which is abused by cybercriminals to develop threats like eCh0raix ransomware. Once the payload file of eCh0raix ransomware is loaded in the computer, it will perform a language check to determine the location of a compromised NAS device and then terminates itself quickly if it finds that the device is from certain countries like the Commonwealth of the Independent States or CIS such as Belarus, Russia, and Ukraine.

eCh0raix ransomware is designed to encrypt common user-generated files like documents, text files, archives, PDF, databases, and many more. It demands a ransom of 0.05 up to 0.06 Bitcoin which is approximately around $567 in exchange for the decrypt key used to restore encrypted files. According to security experts, the decryptors seem t be available for both Windows and macOS.
eCh0raix ransomware also makes alterations in some of the registry keys and sub-keys like Run and RunOnce.

This allows the crypto-virus to execute its attack automatically every time a victim starts the computer. It also scans the system for security and antivirus programs that might interfere with its attack and disables or removes them. Once it finds its targeted files, it encrypts them using a sophisticated encryption algorithm. Following file encryption, it appends the .ech0raix suffix to every compromised file and releases a file named “README_FOR_DECRYPT.txt” which contains the following content:

“All your data has been locked(encrypted).
How to unlock(decrypt) instruction located in this TOR website: http://sg3dwqfpnr4sl5hh.onion/order/[Bitcoin address]
Use TOR browser for access .onion websites.
Do NOT remove this file and NOT remove the last line in this file!
[base64 encoded encrypted data]”

How does eCh0raix ransomware proliferate?

It isn’t clear how eCh0raix ransomware spreads online but it might spread via spam emails. Usually, cyber crooks attached an infected file to spam emails. The infected file may be a document with malicious macro scripts used to install eCh0raix ransomware in the targeted machine. This is why you need to be more cautious in downloading attachments from emails no matter who the sender is as crooks tend to disguise these malware-laden emails to trick users into opening them and downloading the infected attachment.
