This article will aid you to remove Erebus ransomware completely. Follow the ransomware removal instructions given at the end of this article.

Erebus is now the name of a ransomware virus that is named after the Greek God of darkness. Your files will become encrypted and receive the .ecrypt extension when the encryption process is done. Afterward, the Erebus cryptovirus displays a ransom message with demands for payment. Read below to check in what ways you could try to restore some of your data.

Erebus Ransomware – Distribution Tactics

Erebus ransomware could be distributed via different tactics. The payload file that initiates the malicious script for the ransomware that infects your personal computer thrives in the wild. Moreover, there were malvertising campaigns in the past that had spread it via the RIG Exploit Kit.

On top of that, the payload file might have a description that is an old, classic RPG game with the file being less than 1 MB in size.

Erebus ransomware might also be distributing that payload file on social media sites and file-sharing networks. Freeware programs found on the Web might be promoted as useful but also could be hiding the malicious script for the cryptovirus. Do not open files right after you have downloaded them, especially if they come from dubious sources like links and emails. Instead, you should first scan them. Run a security tool and scan them, while also do a check of the size and signatures for each of the files for anything suspicious.

Erebus Ransomware – Detailed Description

Erebus ransomware is also a cryptovirus. It is named after the Greek God of darkness. The ransomware will encrypt files on your computer device while appending the same extension to them when the process finishes.

Interestingly enough, the Erebus ransomware does not encrypt files, contained in the following directories or strings:

  • C:\$recycle.bin
  • C:\$windows.~bt
  • C:\boot
  • C:\drivers
  • %Program Files%
  • %Program Data%
  • %User Profile%
  • %Windows%
  • C:\windows.old
  • %AppDataLocal%
  • %AppDataLocalLow%
  • %Application Data%\adobe\flash player
  • %Application Data%\ati
  • %Application Data%\google
  • %Application Data%\identities
  • %Application Data%\installshield
  • %Application Data%\intel
  • %Application Data%\macromedia\flash player
  • %Application Data%\media center programs
  • %Application Data%\microsoft
  • %Application Data%\mozilla
  • %Application Data%\nvidia
  • %Application Data%\opera
  • \public\music\sample music
  • \public\pictures\sample pictures
  • \public\videos\sample videos
  • \tor browser

In addition to the above list, the following files will be excluded from the encryption process, too:

  • bootsect.bak
  • desktop.ini
  • iconcache.db
  • ntuser.dat
  • thumbs.db
  • wallet.dat

Erebus ransomware could make entries in the Windows Registry to achieve persistence. Those registry entries are usually designed in a way that will start the virus automatically with each launch of the Windows Operating System. Examples of such entries for the Erebus ransomware are the following ones:

→HKEY_CURRENT_USER\Software\Microsoft\
Windows\CurrentVersion\Run
GoogleChromeAutoLaunch_{random alphanumeric characters} = “{malware path}”

The ransom note will appear right after the encryption process completes. The note states what the demands of the cybercriminals are for the ransom price, along with all other instructions and demands for decrypting your files. The note is contained in a file called YOUR_FILES_HAS_BEEN_ENCRYPTED.txt. You can check out the ransom note in the screenshot below:

That ransom note reads the following:

Warning!
Your documents, photos, databases, important files been encrypted!
What happened to your files?
All of your files were protected by a strong encryption whit RSA-2048.
More information about the encryption keys using RSA-2048 can be found here. https://en.wikipedia.org/wiki/RSA_(encryption)
What does this mean?
This means that the structure and data within your files have been irrevocably changed. You will not be able to work with them, read them or see them.
It is the same thing as losing them forever. But with our help, you can restore them.
How did this happen?
Especially for you. On our server was generated the secret key pair RSA-2048 public and private.
All your files were encrypted with the public key. Which has been transferred to your computer via the Internet.
Decrypting of your files is only possible with the help of the private key and decrypt program. Which is on our secret server.
What do I do?
If you do not take the necessary measures for the specified time then the conditions for obtaining the private key will be changed. If you really value your data.
Then we suggest you do not waste valuable time searching for other solutions because they do not exist.
Remember that your machine ID: [Redacted] For more specific instructions please visit your personal home page. There are a few different addresses pointing to your page below:
http://wsb5cxo671abtrsg.j57xi.top/
http://nicc3j2o5rtsllvw.j57xi.top/
If the above address will be unable to open or very slow, follow these steps:
1. Download and install the tor browser.
2. After successful installation, run the browser, waiting to initialize.
3. In the address bar enter:

http://nicc3j2o5rtsllvw.j57xi.top/

The cybercriminals who are behind the Erebus virus have put their demands in the ransom note. You should NOT in any circumstance pay the cyber crooks. Your files may not get recovered, and nobody could give you a guarantee for that. Furthermore, giving money to those criminals will likely just financially support them and probably give them the motivation to create more ransomware or do other criminal activities.

Below you can see the full list with file extensions that the Erebus ransomware seeks to encrypt.

Files that get encrypted will receive the same extension appended to each of them, which is .ecrypt. The encryption algorithm is RSA of 2048 bits or at least, that is what is claimed inside the ransom note.

Files found in the following locations will get encrypted as well:

  • %Program Files%\steam
  • %Application Data%\roaming\microsoft\office
  • %Application Data%\roaming\microsoft\outlook

The Erebus cryptovirus is reported by researches to delete the Shadow Copies from the Windows operating system by utilizing the following command:

→vssadmin.exe delete shadows /all /Quiet
