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

ERIS ransomware is a new file-encrypting threat that was spotted by security researchers spreading using the RIG exploit kit. This new ransomware uses a “.ERIS” extension in marking the files it encrypt. It was first spotted in the last week of May 2019 by security researcher, Michael Gillespie.

Once it enters a computer, ERIS ransomware will make modifications in the computer and encrypts targeted files using Salsa20 (RSA-1024) encryption algorithm. After the encryption, compromised files will become corrupted and the “.ERIS” extension is added at the end of every file’s name. Following data encryption, ERIS ransomware will open a text file named @ READ ME TO RECOVER FILES @.txt which contains the following message:

 “*** ***

*** READ THIS FILE CAREFULLY TO RECOVERY YOUR FILES ***

*** ***

ALL OF YOUR FILES HAVE BEEN ENCRYPTED BY “ERIS RANSOMWARE”!

USING STRONG ENCRYPTION ALGORITHM.

Every your files encrypted with unique strong key using “Salsa20” encryption algorithm:
