Xorist-Frozen Virus – Update November 2018

This Xorist-Frozen variant continues to spread even in November, 2018. The new extension adds two more dots at the beginning of the extension and the word “important” inside it, as shown below:


A new ransom note is also accompanying the new Xorist-Frozen. The note reads the following:

https://coinatmradar.com/ (find a ATM)
https://www.localbitcoins.com/ (buy instantly online any country)
BTC ADRESS : 3NGHjpZpAzmHcgXduMtg7guTKRcixbuotU (where you need to make the payment)
For more information : restore_service@scryptmail.com (24/7)
Subject : SYSTEM-LOCKED-ID: 1989102018

The contents of the note are saved inside a file called “HOW TO DECRYPT FILES.txt“. As Windows has a 255 character limit, it is easy to see how the new (and the old) extension can cause problems while encrypting and how it might cripple the system if there is a hitch.

Xorist-Frozen Virus – Infection Process

The Xorist-Frozen virus attack campaigns can feature multiple infection tactics. Over the years previous samples associated with the malware family tend to spread via email spam messages. They utilize social engineering tactics in order to manipulate the victims into installing the virus files. They can either embedded as file attachments that pose as useful software or applications of interest. In certain cases they can be placed in password-protected archives whose password is inserted in the body contents of the message. Hyperlinks are usually disguised as login forms, password reset links and other typical scenarios.

Similar tactics can be employed by setting up specialist hacker-controlled pages that can also distribute the malware files. They are usually made using templates that copy well-known web services in order to manipulate the victims into interacting with the sites. A common tactic is the creation of fake download portals that are filled with malware of all types.

Browser hijackers are the other mechanism used by criminals to spread the Xorist-Frozen virus. They are malware plugins made for the most popular browsers (Google Chrome, Mozilla Firefox, Microsoft Edge, Safari, Opera and Internet Explorer). One of the intended goals of this type of malware is to change the default browser settings and redirect the victims to a malware page. During the initiation phase various threats can be installed such as the Xorist-Frozen virus. In a similar way various web scripts such as banners, ads and etc. can also be instituted.

Infected documents are the other malware tactic used by the hackers to spread viruses of all types. This tactic employs documents of different types (presentations, spreadsheets and rich text documents) which contain dangerous code. Once the files are opened by the victims a notification prompt appears which asks the users to run the built-in code. If this is done the Xorist-Frozen virus is downloaded from a remote location and the infection follows.

Xorist-Frozen Virus – Analysis and Activity

The Xorist-Frozen virus files acquired by the security specialists showcase that the code is derived from the infamous Xorist ransomware family. The original virus was offered as a RaaS (Ransomware as a Service) and various groups have been using it.

One of the primary reasons why the virus grew into popularity is the fact that the malware creators deployed a builder toolkit allowing practically everyone to create their own custom strains. The Xorist-Frozen ransomware is an example of such a threat. As it is built on a modular foundation it can include different components.

The ransomware infection can begin with the ransomware component which can be programmed into extracting sensitive data from the victims. They are categorized into two main types. The first type is associated with anonymous metrics that are used by the hackers to oversee the attack campaigns. The other type of data is related to the victim’s identity and can directly expose sensitive user data. The engine is programmed to extract strings related to victims: names, address, telephone number, geolocation and etc.

The gathered information is sent to the criminal controllers over a network connection. It can also be fed to the malware engine when the hackers have programmed a stealth protection feature. It can detect the presence of security software such as sandbox and debugging environments, virtual machines and anti-virus products. Their real-time scanning engines can be bypassed or altogether deleted. Advanced Xorist ransomware samples can be made to delete themselves to avoid detection if they fail this step. Follow up behavior patterns usually include the institution of a Trojan module. It allows the criminal operators to spy on the victims in real time, as well as take over their computers at any given time.

The malware can also be programmed into interacting with the operating system. As a result the malware modifications can cause performance issues or application failure. During the modification of the Windows files the Xorist-frozen virus can institute itself as a persistent threat which makes it impossible for the dangerous code to be removed without the use of a quality anti-spyware solution.

Data restoration can be made more difficult by removing the shadow volume copies of all scanned files. The malware engine can also be programmed into accessing the Windows volume manager which allows the Xorist-Frozen virus to access network shares and removable storage devices.

Xorist-Frozen Virus Virus – Encryption Process

Once all components have completed execution the ransomware engine is started. It seeks to process target files using a built-in list of extensions. Older samples use the following list:

*.zip, *.rar, *.7z, *.tar, *.gzip, *.jpg, *.jpeg, *.psd, *.cdr, *.dwg, *.max, *.bmp,
*.gif, *.png, *.doc, *.docx,
*.xls, *.xlsx, *.ppt, *.pptx, *.txt, *.pdf, *.djvu, *.htm, *.html, *.mdb, *.cer, *.p12,
*.pfx, *.kwm, *.pwm, *.1cd, *.md, *.mdf, *.dbf, *.odt, *.vob, *.ifo, *.lnk, *.torrent, *.mov,
*.m2v, *.3gp, *.mpeg, *.mpg, *.flv, *.avi, *.mp4, *.wmv, *.divx, *.mkv, *.mp3, *.wav, *.flac, *.ape,
*.wma, *.ac3.

It then creates a ransomware note in a file called HOW TO DECRYPT FILES.txt which reads the following message:

All your important files were FROZEN on this computer.
Encrtyption was produced using unique KEY generated for this computer.
To decrypted files, you need to otbtain private key.
The single copy of the private key, with will allow you to decrypt the files, is locate on a secret server on the internet;
The server will destroy the key within 36 hours after encryption completed.
To retrieve the private key, you need to pay 0.5 bitcoins
Bitcoins have to be sent to this address: 3N8FxD8y3AKKPZaUBuypw55YYSswmECPxh
After you’ve sent the payment send us an email to : frozen_service_security@scryptmail.com with subject : ERROR-ID-63100888(0.5BTC)
If you are not familiar with bitcoin you can buy it from here :
SITE : www.localbitcoin.com
After we confirm the payment , we send the private key so you can decrypt your system.

The note contains a standard message that is similar to the ones used by other samples derived from the malware family. It shows the unique victim ID which is obtained from the information gathering phase. The hacker operators request the sum of 0.5 Bitcoins which is the equivalent of about $3820 using today’s currency exchange ratio.
