February 2020 Update — RAGNAR_LOCKER Ransomware Campaign Against Remote Desktop Tools in Enterprise

Ever since the first widespread attacks of the Ragnar Locker virus back in December 2019 computer hackers have used it against all kinds of users. A new campaign has been detected this month using a new strategy. At the moment it is not known whether or not the ransomware is being spread by the same hacking group. Before the actual campaign is launched the criminals will perform several reconnaissance operations in order to investigate how best to approach the targeted network.

According to the available information the main engine will first attempt to find a weakness in the network and/or the target computers. The task at this point is to steal a file and then upload it to the hacker-controlled servers. Then they will be blackmailed into paying a ransom sum in order not to release the file to the public. The next step will be to run the actual ransomware component against the rest of the accessible hard drives.

During RAGNAR_LOCKER Ransomware’s operation the security analysis reveals that the main engine will acquire the list of running processes stop some of the active programs and service according to a “string match” list. Here is the list of items that the engine will look for:

vss, sql, memtas, mepocs, sophos, veeam, backup, pulseway, logme, logmein, connectwise, splashtop and kaseya

These processes refer to several categories of software which are commonly installed on enterprise and business computers:

  • Servers — Some of the processes refer to database servers which host sensitive data used by the company and/or web applications.
  • Backup Software — Installed backup software solutions which are configured to perform daily activity can be blocked.
  • VPN and Remote Desktop Software — They are used to remote control the hosts.

It appears that the current version of the ransomware specifically targets remote management services which are used by managed service providers (MSPs). This means that the ongoing February 2020 attack is set against companies and larger networks. Before encryption the internal engine will perform a region check — if the Windows language preferences correspond to countries that are from the former USSR countries the virus will be terminated. During the actual encryption it will also skip files, folders and extensions that have these strings in their names:

kernel32.dll
Windows
Windows.old
Tor browser
Internet Explorer
Google
Opera
Opera Software
Mozilla
Mozilla Firefox
$Recycle.Bin
ProgramData
All Users
autorun.inf
boot.ini
bootfont.bin
bootsect.bak
bootmgr
bootmgr.efi
bootmgfw.efi
desktop.ini
iconcache.db
ntldr
ntuser.dat
ntuser.dat.log
ntuser.ini
thumbs.db
.sys
.dll
.lnk
.msi
.drv
.exe

A distinct personal ID will also be placed in the processed files before the end extension. This means that an algorithm will generate it by acquiring information about the installed hardware parts.

The extortionists want you to pay a ransom for the alleged restoration of your files, same as with a lot of ransomware viruses. .ragnar_ Virus File ransomware could make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows system. All encrypted will receive the .ragnar_44027CDE extension while the symbols after the lower dash are randomly generated ones. That extension will be placed as a secondary one to each file and look something like .ragnar_. Audio, video, image files as well as documents, backups and banking data can be encrypted by the ransomware.

The .ragnar_ Virus File could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet
