What is Locky Ransomware

Update: in some cases .locky files can by decrypted by AutoLocky Decryptor from EmsiSoft. Read below to download free decryptor and leave comments if it works!

Locky is a ransomware virus that encrypts you files using the RSA-2048 and AES-1024 algorithms and demands 0.5 BTC (bitcoins) (equivalent to $207) for receiving “Locky Decrypter” to allow user decrypt his documents and images. This is a very dangerous blackmailing virus and there are currently only a few ways to decrypt your files. It targets a large number of file extensions and encrypts data also on remote network resources, as we saw earlier with DMA Locker. Now we can say with confidence that this feature will become the norm among the ransomware functionality. After encryption, it creates a ransom note (_Locky_recover_instructions.txt) and replaces the desktop background with an image file (_Locky_recover_instructions.bmp).

From February to April 2016, at least 10 different Locky bootloader options were registered. Each of them tried to circumvent antiviruses by hiding the target load in various types of files (.doc, .docm, .xls and .js) issued as unpaid bills. In this guide, we collected all information available that can help you remove Locky ransomware virus and restore infected files.

How Locky Ransomware infected your PC

Locky spreads via spam e-mail attachments as .doc or .xls file. Texts of these e-mails try to ensure the user that attachments contain an important invoice. After downloading, it asks the user to enable macros to be able to see the contents of the document. This macros downloads and runs executable file that starts encrypting user files. Affected file names are modified to unique 16-letter and digit combinations with a .locky file extension. Then Locky Ransomware opens _Locky_recover_instructions.txt file with instructions and URLs that lead to The Locky Decrypter Page.

2. Back up your files

idrive backup

As an additional way to save your files, we recommend online backup. Local storages, such as hard drives, SSDs, flash drives or remote network storages can be instantly infected by the virus once plugged in or connected to. Locky Ransomware uses some techniques to exploit this. One of the best services and programs for easy automatic online backup is iDrive. It has the most profitable terms and simple interface. You can read more about iDrive cloud backup and storage here.

3. Do not open spam e-mails and protect your mailbox

  1. Me he infectado con el virus locky en windows 10 a traves de un falso correo de ENDESA. He intentado recuperar los archivos con el Shadow y efectivamente aparecen copias de una semana anterior a la infeccion. El problema es que cuando exporto los archivos y los intento abrir no me los deja abrir. Al intentar abrir los archivos PDF me pone “Adobe no pudo abrir el archivo debido a que no es un tipo de archivo admitido o esta dañado) y por ejemplo al abrir los archivos word me pone “El archivo de formato XML abierto de Office no puede abrirse porque hay problemas en el contenido”. Tienen alguna solucion?


  2. Buenos días,

    Fui infectado por el virus “.locky ” y tras quitarlo de mi equipo, ahora me falta desencriptar los ficheros infectados. He probado varias herramientas y opciones sin exito (spyhunter, shadow copy,versiones anteriores…) ¿No existe algun desencriptador como para el .locked?

  3. Simplemente bajen algún programa de recuperación de datos como por ejemplo el recurva y listo, ya que ese virus primero los encripta y después borra los archivos; una vez recuperando la información formatear el equipo para eliminar cualquier rastro del virus.
