Locky Ransomware – Update August 2017

Locky has reappeared in the past month, but wasn’t running for all Windows versions and its spam campaign was hindered shortly after. That only means that there is bound to be a comeback for the notorious cryptovirus and it might happen during the month of August, 2017. At the moment there are no reports from victims or malware researchers trying to find new samples of the ransomware, but that surely could be the calm before the storm.

Locky Ransomware – Update July 2017

Locky ransomware continues to infect users worldwide, and is also one of cybercriminals’ most preferred ransomware pieces when it comes to creating copycats. Jaff ransomware appeared last month and is still active as evident by the statistics and users’ complaints over tech support forums.

In factm Jaff mimics Locky ransomware in more than one way, including the payment page design, the way it distributes its infection payload, etc. Similarly to Locky and other ransomware families, Jaff ransomware might also be spreading its payload file via social media and file-sharing networks.

Locky Ransomware – Update May 2017

Locky ransomware keeps spreading and infecting new users even up to this day, but mainly distributes newer variants. The latest of them all is the Locky’s .Loptr File Extension Virus variant which is spreading with malspam campaigns delivering document files embedded inside PDF files. The document files contain hidden macro commands which download the virus from a domain and afterward infect the computer system they were activated on. This clever obfuscation tactic is applied to try and prevent security programs from detecting the threat. As that method of delivering the virus to a computer requires social engineering, experts advise you to not open emails, nor their attachments if you are not certain of their origin.

Locky Ransomware – Spread

Locky ransomware spreads in several ways. One is through spam emails having a malicious file attached. Opening the attachment automatically gets malware inside your computer. The malicious code may also hide inside the body of the email. So, only opening such emails is enough to get you infected, even without getting to the attachment part.

Other ways this virus can spread are via file sharing services and social networks, which may contain similar attachments and files with the Locky ransomware inside. These files might be presented to you as useful or something needed, like an update. Visiting untrusted websites and clicking on links with redirects could also lead to this malware infection.

Locky Ransomware – Information

Locky is classified by researchers as ransomware.

If your computer is infected with it, the ransomware might create new values in the Windows Registry to improve its persistence. That includes an automatic start with every boot of Windows. The modifications are usually made in these registry entries:




It has already been included in several security programs’ definitions and detected by them as shown in the VirusTotal site:


Afterward, the ransomware will create at least one file called _Locky_recover_instructions.txt, which contains the ransom note with instructions on how to pay the ransom. It states the following:


All of your files are encrypted with RSA-2048 and AES-128 ciphers.
More information about the RSA and AES can be found here:

Decrypting of your files is only possible with the private key and decrypt program, All which is on our secret server.
To receive your private key follow one of the links:
1. hxxp: //6dtxgqam4crv6rr6.tor2web(.)org/[mixed letters and numbers] 2. hxxp: //6dtxgqam4crv6rr6.onion(.)to/[mixed letters and numbers] 3. hxxp: //6dtxgqam4crv6rr6.onion(.)cab/[mixed letters and numbers] 4. hxxp: //6dtxgqam4crv6rr6.onion(.)link/[mixed letters and numbers]

If all of this addresses are not available, follow synthesis steps:
1. Download and install Tor Browser:
2. After a successful installation, run the browser and wait for initialization.
3. Type in the address bar: 6dtxgqam4crv6rr6(.)onion / [mixed letters and numbers] 4. Follow the instructions on the site.

!!! Your personal identification ID: [mixed letters and numbers] !!!

Users of Reddit clicked on one of the links inside this ransom note, and have provided an image of what the payment website looks like:


Image Source: Reddit

On that website, there is an alleged Locky Decrypter program and a promise that your files will be decrypted if you pay. Contacting the ransomware makers to pay for the ransom is strongly NOT advised. There is no guarantee your files are going to be decrypted with the above-mentioned decrypter software. Also, paying ransomware creators is like an equivalent of supporting them to make an even worse version of the malware and a tougher encryption.

The Locky ransomware is known to search for and encrypt document and text files. The files that it could encrypt have the following extensions:

→ .doc, .docm, .log, .pap, .info, .gdoc, .asp, .jsp, .json, .xhtml, .txt, .xls, .xlsx, .xml, .docx, .html, .js, .mdb, .odt, .asc, .conf, .msg, .rtf, .cfg, .cnf, .pdf, .php, .ppt, .pptx, .sql

This is not a full list as there could be other file extensions that the ransomware searches for encryption. After encryption, files have the extension .locky. The encryption algorithm of the ransomware, according to its own ransom note is RSA mixed with AES-128 ciphers. This makes a very strong encryption.

The Locky ransomware is known to encrypt file locations which usually contain documents, such as:

  • C:\Users\[UserName]\Documents
  • Desktop\MyDocs\Downloads
  • C:\Documents and Settings\Users\My Documents

For now, it is not known if Shadow Volume Copies are erased from the Windows operating system, but it is likely. So, after removing the ransomware, you should check the third section of the instructions written below for a few ways which can help you try to restore your files.

    Thanks for the info. Just one thing: Thete is no Locky decryptor on the Kaspersky’s webpage.
    There are other decryptors, but none specially tailored for locky.

    buenas tardes

    Se podrian recuperar los archivos si se conecta el disco duro con un adaptador o haciendolo esclavo??? Existe riesgo de al hacer esto la computadora que este visualizando los arhcivos se infecte tambien ??


  3. Avatarbronger

    Le souci c’est que shadow explorer restaure les fichiers word à une date postérieur à l’attaque de locky, c’est donc un coup d’épée dans l’eau…

    I have a client who complained about his laptop being infected by Locky. At this very moment I am performing a malware check on the whole network and I have cleaned the infected PC. Fortunately for her, i managed to find a backup of the data on another flash drive.

    Do you know by any chance if Locky can spread to other PCs on the network or smartphones? Does it infect servers?

    1. AvatarKenny Black

      Yes if Network share is mapped it will treat it as a drive

  5. Avatarsha

    hi tony,

    the ransomware is not reported to have multi-device spreading capabilities as far as i am concerned. locky uses a lot of methods to spread, however so be careful and teach your client how to spot malware!

  6. AvatarJosué David
