How Does Erebus Ransomware Infiltrate the System?

The first Erebus ransomware samples were identified back in September 2015. The primary attack campaigns are targeted against English-speaking computer users.

The operators of the virus mainly use spam email campaigns that utilize social engineering tricks. The goal of the criminals is to make the targets infect themselves by interacting with the Erebus ransomware. This can be done by opening file attachments or links placed in the body of the messages.

Browser hijackers and other malicious add-ons and software can lead to an Erebus ransomware infection. They are frequently found on hacked or hacker-controlled sites. Beware that the virus can also be installed via direct hacker intrusion attempts.

Infection Flow of Erebus Ransomware

The Erebus ransomware is a new encryption virus that is of unknown origin. The security experts at this moment cannot deduce if this is an entirely new creation or an offspring of a malware family.

The malware features an AES encryption engine which targets popular user files and encrypts them using the cipher and then extorts the victims for a ransomware payment fee.

Each infected host receives an unique hash ID which is appended to the compromised files using the following pattern – {hash}.ecrypt.

The crafted ransomware note reads the following message:

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. xxxxs://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.
