DEATHFILE Virus Files of MedusaLocker Ransomware

The Deathfile virus belongs to the MedusaLocker ransomware family. This ransomware encrypts all user’s data on the PC (photos, documents, excel tables, music, videos, etc), adds its specific extension to every file.

Deathfile Virus

☝️ Deathfile can be correctly identify as a MedusaLocker ransomware-type infection.

Deathfile adds its specific “.deathfile” extension to the name of every file. For example, your photo named as “my_photo.jpeg” will be transformed into “my_photo.jpeg.deathfile“, report in Excel tables named “report.xlsx” – to “report.xlsx.deathfile“, and so on.

Inside of the ransom note, there is usually an instruction saying about purchasing the decryption tool. This decryption tool is created by ransomware developers.

Example of encrypted .deathfile files

How did I get MedusaLocker?

When the MedusaLocker ransomware is mounted to your PC, it will do different startup routines to prepare your computer for encryption

Step 1

MedusaLocker will create the Registry value EnableLinkedConnections under the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System registry key and also established it to 1. This is done to make certain mapped drives come also in a UAC launched process.

Step 2

Next, ransomware will restart the LanmanWorkstation service in order to make certain that Windows networking is running which mapped network drives come.

Step 3

MedusaLocker will seek as well as end the complying with procedures in order to shut down security programs and to make certain all data files are closed and easily accessible for encrypting:

wrapper, DefWatch, ccEvtMgr, ccSetMgr, SavRoam, sqlservr, sqlagent, sqladhlp, 
Culserver, RTVscan, sqlbrowser, SQLADHLP, QBIDPService, Intuit.QuickBooks.FCS, 
QBCFMonitorService, sqlwriter, msmdsrv, tomcat6, zhudongfangyu, SQLADHLP, 
vmware-usbarbitator64, vmware-converter, dbsrv12, dbeng8, wxServer.exe, 
wxServerView, sqlservr.exe, sqlmangr.exe, RAgui.exe, supervise.exe, Culture.exe, 
RTVscan.exe, Defwatch.exe, sqlbrowser.exe, winword.exe, QBW32.exe, QBDBMgr.exe, 
qbupdate.exe, QBCFMonitorService.exe, axlbridge.exe, QBIDPService.exe, httpd.exe, 
fdlauncher.exe, MsDtSrvr.exe, tomcat6.exe, java.exe, 360se.exe, 360doctor.exe, 
wdswfsafe.exe, fdlauncher.exe, fdhost.exe, GDscan.exe, ZhuDongFangYu.exe

Step 4

Finally, it gets rid of the Shadow Volume Copies to ensure that they can not be made use of to bring back files, gets rid of back-ups made with Windows back-up, and also disables the Windows automatic start-up repair work making use of the complying with commands:

vssadmin.exe Delete Shadows /All /Quiet
wmic.exe SHADOWCOPY /nointeractive
bcdedit.exe /set {default} recoveryenabled No
bcdedit.exe /set {default} bootstatuspolicy ignoreallfailures
wbadmin DELETE SYSTEMSTATEBACKUP
wbadmin DELETE SYSTEMSTATEBACKUP -deleteOldest

Step 5

MedusaLocker will currently begin to scan the computer’s drives for files to encrypt. When encrypting documents, it will miss all data that have the extensions.exe,. dll,. sys,. ini,. lnk,. rdp,. encrypted (or other expansion utilized for encrypted files) in addition to data in the adhering to folders.

USERPROFILE
PROGRAMFILES(x86)
ProgramData
\AppData
WINDIR
\Application Data
\Program Files
\Users\All Users
\Windows
\intel
\nvidia

When encrypting documents, it will use AES file encryption to encrypt the data and afterwards the AES key will be encrypted by a RSA-2048 public key consisted of in the virus executable.

For every data that is encrypted, it will add among the adhering to extensions depending on the version of the ransomware.

• .encrypted
• .bomber
• .boroff
• .breakingbad
• .locker16
• .newlock
• .nlocker
• .skynet

When done, the ransomware will rest for 60 secs and afterward scan the drives again for new files to encrypt.

When mounted, this ransomware will likewise duplicate itself to %UserProfile%\AppData\Roaming\svchostt.exe and also create a scheduled job that releases the program every 30 mins in order to continue to be resident.

How to remove Deathfile virus?

In addition to encode a victim’s files, the Deathfile infection has also started to install the Azorult Spyware on system to steal account credentials, cryptocurrency wallets, desktop files, and more.

To ensure the user that ransomware distributors really have the decryption tool, they may offer to decrypt several encrypted files. And they are the single owners of this decryption program: Deathfile ransomware is a completely new type, so there is no legit program from anti-malware vendors, which can decrypt your files. But such a situation is in momentum: decryption tools are updating every month.

However, paying the ransom is a bad decision, too. There is no guarantee that Deathfile ransomware developers will send you the decryption tool and a proper decryption key. And there are a lot of cases when ransomware distributors deceived their victims, sending the wrong key or even nothing. In the majority of cases, there is a way to recover your files for free. Search for available backups, and restore your system using it. Of course, there is a chance that the backup you found is too old, and does not contain a lot of files you need. But, at least you will be sure that there is no malware in your system. However, to ensure that there are no malicious programs in your system after the backup, you need to scan your PC with anti-malware software.

Deathfile ransomware is not unique. These examples of ransomware act in a similar way: encrypting your files, adding a specific extension, and leaving a great number of ransom money notes in every folder. But there are two things that make difference between these ransomware – cryptography algorithm, which is used for file encryption, and ransom amount. In some cases, victims are able to decrypt their files without any payments, just using free solutions produced by several anti-malware vendors, or even with the decryption tool which is offered by ransomware creators. The last scenario is possible when ransomware distributors have typed your decryption key inside of a ransom money note. However, as you can already guess, such luck is a very rare thing. Ransomware is created for money gaining, not for jokes or scaring.

Frequently Asked Questions

How сan I avoid ransomware attack?

Deathfile ransomware doesn’t have a superpower.

You can easily protect yourself from its injection in several easy steps :

• Ignore all emails from unknown mailboxes with a strange unknown address, or with content that has likely no connection to something you are waiting for (can you win in a lottery without taking part in it?). If the email subject is likely something you are waiting for, check carefully all elements of the suspicious letter. A fake email will surely contain a mistake.
• Do not use cracked or untrusted programs. Trojans are often distributed as a part of cracked software, possibly under the guise of “patch” which prevents the license check. But untrusted programs are very hard to distinguish from trustworthy software, because trojans may also have the functionality you need. You can try to find information about this program on the anti-malware forums, but the best solution is not to use such programs.
