.neras ransomware – A newbie threat for computer
users
This blog will help you to get rid of the newly discovered .neras ransomware.
Apart from encrypting the files, it restricts the access to anti – virus in the affected
system.
Guide to remove .neras Ransomware
The DJVU ransomware is back with its new variant - .neras ransomware. It is a
dangerous crypto virus that encrypts the data and makes it unusable. Once, it
infiltrates the system, it immediately search for the targeted files and locks them

Understanding .neras Ransomware
The methodology of .neras ransomware is similar to the DJVU family. It must be
clear that Neras encrypts the data and blackmail the victims to pay ransom. It adds
‘.neras’ extension to the files and made them unusable. Unfortunately, it uses a
powerful cryptography algorithm which generates a unique decryption key on the
hacker’s server. The decryption key is exchanged for large amount of ransom, in
the form of bitcoins. Hence, it is next to impossible to manually restore .neras files.
After successful encryption, the malicious ransomware scans every inch of the
system for the targeted files. The targeted files are commonly found in most of the
systems today. It includes the important productivity documents, images, audio
files and what not! When the victim tries to open the .neras encrypted files, a
ransom-demanding message is displayed on the screen. The dangerous neras
ransomware targets all versions of windows, including Windows 7, Windows 8
and windows 10.
Apart from locking the files, it also deletes ‘Shadow Volume Copies’ that are
found on the affected system. It is done to complicate the restoration of the
encrypted files. In order to restore the corrupted data, the user gets ready to pay the
demanded ransom.

ransomware.
Distribution Technique
The exact method used by developers to proliferate .neras ransomware is still a
mystery. However, spam campaigns, Trojans, software crack and fake software
update tools are a few devastating methods. Let us understand these methods in
detail:
Spam campaigns, is a way to send a spam e-mail with malicious attachment. The
malicious attachment could be in the form of MS Word document, PDF or Zip file.
Unfortunately, these are used to spread other malicious malware in your system. A
catchy subject line is written to make them look legitimate. Hackers trick the users
into believing that these e-mails are from a shipping company. It informs about an
undelivered package or a shipment made previously. As soon as the user clicks on
the link or open the file, it leads to the installation of the nasty .neras virus.
Trojan ransomware, the malicious program which makes a back door entry in the
system is designed to cause chain infections. Once installed, they download other
malicious files in the system.
Software cracking is a way to freely activate the paid applications. However,
hackers design them in a way that they instead of performing their task install
malicious software in the system.
Once it infiltrates the system, it may cause great damage to the targeted files.
Therefore it is necessary to scan the system with an antivirus on regular basis.
Keep in mind, as soon as you detect .neras ransomware, focus on removing it
completely from your system.
Threat Behavior
The dangerous neras ransomware infiltrates your system with or without your
knowledge. After successful encryption, it restricts the access to the encrypted
files. It appends ‘.neras’ extension so that the user cannot open the files anymore.
Unfortunately, the encryption algorithm used by .neras ransomware is not yet
revealed. However, the cryptographies used are strong and creates a private key on
the remote server. This is the decryption key for the locked files. Developers, use
this key to blackmail the victim and to extort money from them.
When the victim user tries to open the corrupted files, the ransomware displays a
ransom – demanding message on the screen. Large amount is demanded in the
form of bitcoins – a crypto currency. The only way to get the key is by paying the
asked ransom.
Ransom – Demanding Message:
The ransom message notifies you on how to pay the ransom. Cyber criminals ask
for $980 (in bitcoins). Lucky victims, who contact the hackers within 72 hours of
the ransomware attack, get a discount of 50%. The amount of ransom reduced to
$490 (in bitcoins).
Though you can use the decryptor tools to remove .neras ransomware, yet it does
not work in most of the cases. In many cases, it is impossible to decrypt the files
without the private key.
Keep in mind, it is not necessary than you will receive the decryption key after
paying the ransom. Furthermore, the ransom amount helps these cyber criminals to
commence their next malicious project.
