Defray 2018 Virus – Distribution Techniques

The Defray 2018 virus is a ransomware that is launched by an unknown group of hackers. The detected attack campaigns seem to target mainly English-speaking in a limited campaign. It is very possible that future releases will use use the most popular distribution methods.

A common strategy is to coordinate SPAM email messages that make use of phishing tactics. They are designed to appear as being sent by a well-known company or service and almost all scenarios will coerce the victims into opening the attached file or click on a link in the body contents. The design of the messages and text contents will be just like a regular notification. In most cases it my be very hard to distinguish between a real and a fake message.

The hackers can construct fake web pages that impersonate vendor download pages and popular web portals. The Defray 2018 virus files can be spread via other methods like file-sharing networks, one of the most popular places where the files can be spread is BitTorrent.

En-mass ransomware infections can also be spread by infecting other files and using them as payload carriers. A typical example is the use of documents of all popular type: spreadsheets, text documents, presentations and databases. Whenever they are opened a notification prompt will appear asking the users to enable the built-in scripts. If this is done they the scripts will download the payload from a remote server and execute it.

The other popular payload type is the malicious installer. The criminals will take the legitimate setup files of popular apps from the official sources and modify them to include the virus download code. After that they will spread as legitimate and safe downloads.

Large-scale campaigns make use of browser hijackers — malicious extensions made for the most popular web browsers. To coerce the victims into installing them the hackers will use fake developer credentials and user reviews. When they are installed on the computers typically changes to the installed browsers will take place — they will change the default options to redirect the users to a hacker-controlled page. Alongside this action the Defray 2018 virus will also be deployed.

Defray 2018 Virus – Detailed Analysis

Once the Defray 2018 virus is deployed it will initiate a typical ransomware infection behavior pattern. It appears to originate from an older release called “Defray” which shows that it might be made by the same hacker or criminal group. The captured samples appear to be early testing releases which can be updated in future campaigns.

The current version of the Defray 2018 virus includes only the bare ransomware module. We anticipate that future releases will include more components.

Future releases of the Defray 2018 virus can start with the information gathering module. It will scan the infected system for sensitive information that can be harvested. The first category of data is one that is related to the personal information of the victim user. The hackers can use it to expose their identity and conduct crimes such as identity theft or financial abuse. Example contents include the following: their real name, address, location and any stored username and password combinations.

The other type of data that is collected is related to the generation of an unique victim ID. It is usually made by creating a report of the installed hardware components, user configuration and regional settings.

This information can be used by the next module in the pattern — security bypass. It will scan the local contents for any security software that can interfere with the virus’s execution. Typically it will scan for apps like anti-virus, firewalls, debug environments and virtual machine hosts. Their real-time engines can be disabled or entirely removed. In some configurations if the virus is unable to do so it can remove itself to avoid detection.

At this point the Defray 2018 virus will be able to obtain full control of the infected machine. A list of the possible actions is the following:

  • Windows Registry Changes — The engine will modify values belonging both to the operating system and any third-party installed apps. This can make them inaccessible or cause severe performance issues.
  • Persistent Virus Installation — The ransomware threat may be installed in a way which will automatically start it once the computer boots. The additional danger here is that this step can disable access to certain recovery menu options. This will make most manual user removal instructions ineffective.
  • Additional Threats Installation — Active Defray 2018 ransomware infections can be used to deploy other malware. This is especially useful when the main threat has disabled the security software and has total system control.
  • Trojan Instance — The Defray 2018 virus can be used to load a Trojan virus infection. It will setup a secure and encrypted connection to a certain hacker-controlled server. It allows the operators to take over control of the infected hosts at any given time, hijack user data and also spy on the victims.

To make recovery more difficult the engine can also delete sensitive user data such as System Restore Points or Shadow Volume Copies. In these cases the hackers will need to use both an anti-spyware utility along with a data recovery software.

Defray 2018 Virus – Encryption Process

As soon as all modules have completed execution the encryption engine will be started. Like other malware it will use a built-in list of target file type extensions that will be processed with a strong cipher. The resulting data will be inaccessible and the victims will be blackmailed into a “decryption fee”. An example list will usually target the following data types:

  • Archives
  • Backups
  • Documents
  • Music
  • Videos
  • Photos
  • Databases

All processed files will be renamed with the .***777 extension. The following ransomware note will be created in folders where the ransomware process has been started — !!!_Read_Me_How_To_DeCrypt_Files_!!!.tXt. Its contents reads the following:
