Since then the Matrix ransomware slightly disappeared from the threat landscape, but now it seems to be back and it is being delivered through malvertising campaign that triggers an Internet Explorer flaw (CVE-2016-0189) and Flash one(CVE-2015-8651).
When a computer is infected with the latest variant of the Matrix Ransomware, the malicious code will encrypt the files on the victim’s machine, scramble their file names, and append the .firstname.lastname@example.org extension to the file scrambled name.
The ransomware also drops a ransom note (#_#WhatWrongWithMyFiles#_#.rtf) in every folder that contains files it encrypted, then it will display a ransom screen.
