What is RedEye?

RedEye Ransomware is a newly discovered malware created by the “iCorex” (a YouTube channel). This author is notoriously known for programming such malware. Annabelle ransomware was also created by iCorex that wreaked havoc early this year and targeted many high profile companies.

Like Anabelle, This infection can also be spread via social networking site Twitter. The malware is programmed to exploit user files by encrypting the data using Rijndael-Algorithmus – AES – 256 Bit encryption algorithm on all the hard drive files to deprive the user from accessing them.  It also targets the Master Boot Record (MBR) of the operating system making it paralytic to take the control.  This is done by downloading the pay load & then by waiting for the next hard boot.

The moment the system is booted or restarted by the user, the entries of this ransomware takes the control and replaces everything with .redeye extension. IT then displays the ransom message to threaten the user for the payment.

The infection is designed with the sole purpose to earn ransom amount in Bitcoin for the alleged restoration of the file.

How does the infection invade the system?

The infection is spread via spam email attachment that contains a media file especially image and audio file. The file size is around 35 MB which is huge.

This email attachment is comprised of three “.wav” files:

  1. child.wav
  2. redeye.wav
  3. suicide.wav

These three audio files play a creepy sound with the intention to scare people.

After successful infiltration and encryption of user data, the users are notified about the encryption through a ransom note stating that a unique decryption key is required to restore files. The note also declares that the victim is entitled to a ransom of 0.1 Bitcoins ($765 USD) within 4 Days to recover the compromised data.

Also, the note threatens the victim to destroy the data if they fail to pay the ransom on time.

How does it affect the computer system?

Ransomwares are designed to serve one ultimate and obvious purpose which is monetary gain.

Just like its predecessor Annabelle, Redeye performs a series of actions to make removal quite difficult. Once infiltrated, the first job of this infection is to disable task manager to prevent its detection. It then hidesthedrives and ceases the access to all the files.

RedEye Ransomware claims to encrypt files securely with AES256 (Advanced Encryption Standard – key length 256 bits). The malware renders the files useless by overwriting files with 0 bytes, and appends the same with “.RedEye” extension.

The Options available in the ransomware include the possibility to:

  1. View encrypted files
  2. Decrypt them
  3. Get support
  4. Destroy PC

If the last option i.e. Destroy PC is selected, a GIF is displayed in the background, with two options to select: “Do it” button to proceed with the operation and a “Close” button to close the image.

If “Do it” is selected or when 4 days’ time runs out, the malware reboots the machine and replaces the MBR (Master Boot Record).

How to get rid of this ransomware?

The MBR or the files can be restored if the computer is shut down immediatelyor rebooted to safe mode as soon asthe ransomware is discovered in the system.

However to be on a safer side, you are advised to maintain regular data backup and store them on a remote server or unplugged storage devices.
