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 can I open “.deathfile” files?

No way. These files are encrypted by Deathfile ransomware. The contents of .deathfile files are not available until they are decrypted.

🤔 Deathfile files contain important information. How can I decrypt them urgently?

If your data remained in the .deathfile files are very valuable, then most likely you made a backup copy.
If not, then you can try to restore them through the system function – Restore Point. All other methods will require patience.

🤔 You have advised using GridinSoft Anti-Malware to remove Deathfile. Does this mean that the program will delete my encrypted files?

Of course not. Your encrypted files do not pose a threat to the computer. What happened has already happened.

You need GridinSoft Anti-Malware to remove active system infections. The virus that encrypted your files is most likely still active and periodically runs a test for the ability to encrypt even more files. Also, these viruses install keyloggers and backdoors for further malicious actions (for example, theft of passwords, credit cards) often.

🤔 Deathfile virus has blocked infected PC: I can’t get the activation code.

In this situation, you need to prepare the memory stick with a pre-installed Trojan Killer.

🤔 What can I do right now?

You can try to find a copy of an original file that was encrypted:

  • Files you downloaded from the Internet that were encrypted and you can download again to get the original.
  • Pictures that you shared with family and friends that they can just send back to you.
  • Photos that you uploaded on social media or cloud services like Carbonite, OneDrive, iDrive, Google Drive, etc)
  • Attachments in emails you sent or received and saved.
  • Files on an older computer, flash drive, external drive, camera memory card, or iPhone where you transferred data to the infected computer.

To report the attack, you can contact local executive boards. For instance, if you live in USA, you can have a talk with FBI Local field office, IC3 or Secret Service.

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.
  • And to be sure about the safety of the files you downloaded, use GridinSoft Anti-Malware. This program will surely be a perfect shield for your personal computer.
