Jemd Virus – Distribution Techniques
The Jemd virus is a dangerous computer virus that appears to be descended from the Delphimorix ransomware family. The captured samples appear to be early testing releases that are being spread using a limited number. It is very possible that the ongoing attacks are the early test releases which are used to test whether or not the ransomware is deemed successful.
The Jemd virus can be distributed using various techniques among which the most popular ones are the following:
- Email SPAM Messages — The email messages sent by the hacker operators will be designed to appear as being sent by the well-known companies or services. This is done by implementing design elements and text that convince the recipients into interacting with the linked or attached files.
Additional infections can be caused by the use of browser hijackers — malicious plugins which are made for the most popular web browsers. The samples are usually uploaded to their relevant repositories of plugins, usually with fake user reviews and developer credentials. Their descriptions will promise new feature additions or performance optimizations in order to entice the users into downloading and installing them. As soon as this is done the necessary changes will be done to the browser which in-turn will lead to the Jemd virus delivery.
The virus samples can also be spread via file-sharing networks like BitTorrent where both legitimate and pirate contents can be found.
Jemd Virus – Detailed Analysis
The Jemd virus as derivative of the Delphimorix ransomware family follows the typical infection patterns as observed with the known samples so far. The security researchers confirm that the observed attacks are still an early version.
We anticipate that future updates will implement many of the distinct characteristics of advanced ransomware. A partial list of possible additions includes the following:
- Data Stealing — Information hijacking is a popular module that is available with most viruses. The infection engine will scan the local computer, operating system contents, memory and even connected network shares, if configured so, for data that is considered useful. Such may be unique hardware metrics, operating system data and etc. Personal information can also be harvested using the engine: name, address, location, phone number and any stored account credentials.
- Files Theft — Before the encryption process is started the Jemd virus can hijack files located on the infected machines.
- Security Bypass — Using the collected information the Jemd virus can scan for security software such as firewalls, anti-virus suites and debug environments (sandboxes). Their real-time engine can search for malware threats and neutralize them. This is why the Jemd virus can be programmed into disabling them.
- Windows Registry Changes — The Jemd virus can access the Windows Registry in order to modify strings belonging both to the operating system and third-party installed applications.
When these actions have completed the Jemd virus will have control of the infected machine. This will result in the ability to hook up to other applications and services, including those belonging to the operating system.
In many cases advanced configuration options can enable the persistent installation of the ransomware. This means that the virus will be executed every time the computer is started, thus reconfiguring system configuration files, boot options and etc.
In many cases infections such as this one can lead to the installation of malware threats like Trojans which setup local client instances that connect to hacker-operated server and report the collected information. Their use allows the malicious actors to spy on the users, hijack their data and take over control of the compromised hosts.
The other popular category of threats that can be obtained include cryptocurrency miners which have various different forms — from small scripts to large applications. They will take advantage of the available system resources in order to carry out complex mathematical tasks. The resources that are used include the CPU, GPU, memory and hard disk space. When a completed task is reported to the servers the criminal operators will receive income in the form of cryptocurrency which will directly be wired to their wallets.
While this version does not delete System data, future updates to the Jemd virus code can locate and remove Backups, Restore Points and Shadow Volume Copies. If this is done so then the victims will need to use a professional-grade backup solution to recover their systems.
Jemd Virus – Encryption Process
The encryption module is started after the other modules have completed running. The collected samples of the Jemd virus do not encrypt files at this moment using the typical behavior used by ransomware. We expect that this will change and that the future releases of the threat will process user data according to a built-in list of target file type extensions. An example one would be the following:
The security reports reveal that the associated ransomware note is created in a file called Recovery.txt which has the following contents:
All your files were encrypted by jemd.
