The end goal of the ransomware is to get the victims to pay a ransom in order to get the crooks to recover the files, encrypted by this infection. However, this is highly inadvisable and if your computer has been infected by this variant of Magniber ransomware, we advise that you read this article and learn how to remove this virus from your PC and restore files, encrypted by it.

.ndpyhss Ransomware – Distribution Methods

For the .ndpyhss files virus to be distributed and infect the maximum amount of victims out there, the crooks behind the virus may participate in massive spam campaigns, the purpose of which is to get victims to open a malicious e-mail attachment or click on a malicious web link. The idea behind those e-mails is that they often pretend to come from big and legitimate companies from the likes of:

  • DHL.
  • FedEx.
  • PayPal.
  • eBay.

The e-mails often contain convincing statements embedded within them such as to prompt victims to open e-mail attachments whose main idea is to cause the infection.

In addition to via e-mail, the Magniber ransomware virus may also spread by posing as a legitimate type of file that is upladoaded online while posing as a legitimate file. This basically means that the file may pretend to be:

  • Setup of a program.
  • Game patch or crack.
  • License activator.
  • Key generator.

.ndpyhss Ransomware — Targeted Vulnerabilities

The Magniber ransomware and its associated .ndpyhss virus strain have been found to use various exploits that target specific vulnerabilities. One of the distinct features of this particular threat is that during the 2017 attack campaigns the threat was using a mechanism called filtering gate nick named Magnigate which distributed Cerber ransomware. This particular threat allows the operators to defined specific values that are selected in the targets. This has allowed the criminals to carry out fine-tuned attacks that have plagued several countries in Asia. Their success has provoked other ransomware authors to selectively filter out the intended victims in a similar way.

The Magniber virus was delivered using two specific exploits targeting common vulnerabiliites:

  • CVE-2018-4878 — A use-after-free vulnerability was discovered in Adobe Flash Player before 28.0.0.161. This vulnerability occurs due to a dangling pointer in the Primetime SDK related to media player handling of listener objects. A successful attack can lead to arbitrary code execution.
  • CVE-2018-8174 — A remote code execution vulnerability exists in the way that the VBScript engine handles objects in memory, aka “Windows VBScript Engine Remote Code Execution Vulnerability.” This affects Windows 7, Windows Server 2012 R2, Windows RT 8.1, Windows Server 2008, Windows Server 2012, Windows 8.1, Windows Server 2016, Windows Server 2008 R2, Windows 10, Windows 10 Servers.

.ndpyhss Magniber Ransomware – Infection Activity

Once the .ndpyhss files variant of Magniber ransomware are dropped on the victims computers, the malware uses several modules which are dropped on the infected machine:

Main Infection Module – This module has a trojan-like capabilities which could turn the ransomware into spyware to steal and take control of computers.
Data Theft modules – they may be used to steal sensitive data, such as passwords, financial information or files.
Additional Malware dropper – this module may update the existing virus files or download another virus on the infected computer.

The malicious files are copied to a folder, which may also be changed after this happens. As soon as this is done, the malware’s files are changed into radnom names and may exist in te following Windows directories:

  • %Temp%
  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%

In addtion to this, the ransomware may also spawn processes as an administrator to perform various malicious activities such as information gathering activities that check if the virus is ran on a real system or a virtual drive and if that is the case, the malware may start to delete itself and will never run encryption. But if it’s running on an actual computer, it may start to drop it’s ransom note file, called README.txt, which contains instructions on how to pay a hefty ransom fee in order to restore the files that have been encrypted by this virus. The ransom note usually leads victims to the payment page of Magniber ransomware, which looks somewhat like the following:

In addition to instructions on how to pay the ransom, the virus may also provide the free decryption of 1 file to the victims, to prove that this blackmainling works.

.ndpyhss Files Virus – Encryption Process

For this variant to encrypt the files on the victims’ computers, it uses a pre-set list of file extensions which it targets for encryption. If those types of files are detected within the victim’s computer, the ransomware virus encrypts them:

But this variant of Magniber ransomware is also a clever one, which skips encrypting files In several important Windows folders in order to leave the infected machine intact and functional. The folders in it’s so-called “whitelist” appear like the following:

→ :\documents and settings\all users\
:\documents and settings\default user\
:\documents and settings\localservice\
:\documents and settings\networkservice\
\appdata\local\
\appdata\locallow\
\appdata\roaming\
\local settings\
\public\music\sample music\
\public\pictures\sample pictures\
\public\videos\sample videos\
\tor browser\
\$recycle.bin
\$windows.~bt
\$windows.~ws
\boot
\intel
\msocache
\perflogs
\program files (x86)
\program files
\programdata
\recovery
\recycled
\recycler
\system volume information
\windows.old
\windows10upgrade
\windows
\winnt

After the encryption process has completed, the Magniber ransomware virus assigns often a random file extension, one variant of which was detected by researcher Michael Gillespie to use the .ndpyhss file extension. The files appear like the following after they have been encrypted by Magniber Ransomware:
