The .JayTHL virus is a ransomware that is currently set against target end users on a global scale. There is no information available about the hacking group behind it. It is believed to be a new iteration of the famous ransomware family. This is one of the reasons why we believe that the hackers are experienced.
Once the .JayTHL virus has started it will execute its built-in sequence of dangerous commands. Depending on local conditions or the specific hacker instructions various actions will take place. The file encryption will begin after them — the encrypting component will use a built-in list of target file type extensions. In the end the victim files will be renamed with the .JayTHL extension.

.JayTHL Virus – Spread and Impact
The .JayTHL virus is a new sample that is derived from one of the well-known ransomware families — SamSam. It can be distributed using different distribution tactics depending on the target victims. At the moment there is no information available about the hacking group behind the ongoing attacks. This allows us to presume that the most popular tactics are to be used.
This can include the running of phishing strategies which can be either sent as email messages or posted to hacker-controlled servers. The main goal of the criminals is to confuse the recipients and visitors into believing that they are viewing safe and trustworthy contents. This is done by impersonating famous services and companies.
The hackers can also infect the target users by creating malware-infected files that can be easily uploaded to these hacker-controlled sites or sent as links that are embedded in the emails. Large-scale infections are commonly done by posting the data over file-sharing networks like BitTorrent and also found on social network sites where the hackers can post the files on their public profiles, in private messages and in group conversations. The two most widely used file types are infected documents of all popular formats or malware app installers — usually popular software that is frequently downloaded by the end users.
The .JayTHL virus can exhibit different behavior depending on the current version or specific hacker instructions. The captured sample appears to focus on starting the main engine following the infection. It is confirmed that this will trigger the removal of Shadow Volume Copies — this is done in order to make data recovery and virus removal very difficult. This is often accompanied by the deletion of backups, user data, restore points and etc. In combination with other techniques this can make it very hard to restore the machines.
Future variants can include other functionality such as the following:
- Information Gathering — This is one of the most common modules which are run. The built-in module will acquire information that can reveal much about the identity of the victims. In many cases this is done in order to commit other crimes such as identity theft and blackmail. The .JayTHL virus can be programmed to construct an ID string based on the collected information about the hardware.
- Persistent Installation — The malware can be installed in a way which will automatically launch it as soon as the computer is powered on. It can also block access to the recovery boot options.
- Other Malware Infections — The virus can be used to install other kinds of viruses onto the computer: Trojans, miners or hijackers.
- Windows Registry Changes — Some viruses have also been found to edit values in the Registry or create new ones which are specific for the virus. This can result in severe performance issues, unexpected errors and data loss.
At any time other modules can be installed and run. When everything has finished running the actual file encryption will start. Like previous samples and common ransomware a strong cipher will be applied to the target user data. The files can be any of the following:
- Multimedia Files
The .JayTHL extension will be applied to the target files. To extort the victims a ransom note will be created in a file called FuckYouJayTHL_HELP_ENCRYPTED_FILES.TXT.
