EVEREST ransomware is the cryptovirus which encrypts data using AES and DES algorithms 

EVEREST ransomware
EVEREST ransomware is a threat that can also be called Everest Locker because developers state this name in the ransom note.

EVEREST ransomware is a virus that locks users' data and demands ransom in cryptocurrency. Also known as EVEREST LOCKER, this cryptovirus hails from the already known family of Everbe 2.0 ransomware. Ransomware infiltrates the system without your consent, then it encodes various files on the device and appends .[everest@airmail.cc].EVEREST file extension to the target data. This file marker indicates modified data which is inaccessible due to the encryption algorithm.[1] When your files are locked, virus developers place the ransom file on the system in every folder with encrypted data and on your desktop. It is called EVEREST LOCKER .txt or 新建文本文档.txt which can be found on the device and contains more information about the initial attack.

A ransomware payload dropper hide in spam email file attachments

Cyber infections have multiple distribution ways and can be easily spread around the world. Malicious script can be initiated from the payload directly, or other malicious programs distribute ransomware around. When the file lands on your system and code is launched, the system becomes infected, and ransomware starts its infiltration.

Spam email box fills up with commercial emails from companies and advertisers, but there is a possibility that malicious emails go straight to your email box and not as spam. Since malicious actors disguise their emails with known company names and subject lines like Invoice or Receipt people, tend to open them without paying much attention.

When you receive an email that contains financial information or MS Word or Excel file be aware that documents may be filled with malicious macros. Do not open the email if you haven't waited for one and do not download any data on the system without checking the sender and email itself.
