HyperStack Trojan – Virus Infection Methods
The HyperStack Trojan is a custom malware that has been detected in an ongoing campaign against European government organizations. It is built on the foundations of prior malware that have been constructed by this hacking group. Many of them have been updated with new code and combined in this new iteration.
This hacking group is known for conducting advanced espionage operations against high-profile targets — most of their attacks so far use custom and very complex viruses that are specially designed to infiltrate the target networks and cause as much damage as possible. In this ongoing attack, the HypereStack Trojan is used in combination with other viruses such as Kazuar and Carbon, all of them are categorized as remote procedure-call based backdoors. They are an advanced type of remote control malware that uses a special network connection to receive commands from a hacker-controlled server.
This particular virus is distributed using direct intrusion attemps. This is done by scanning the target networks for open ports and running services that can interpret RPC calls from the Internet. The Trojan will automatically attempt to login using numerous combinations of default credentials, or a brute force attempt will be made. Other ways of getting infected with this virus include its deployment by other existing malware. In future campaigns, other infection strategies can be considered, depending on the goals of the hackers and their target users.
HyperStack Trojan – Virus Capabilities
To a large extent, the captured Trojan samples indicate that this particular threat uses a traditional approach — the locally deployed agent will establish a secure connection to a hacker-controlled server, allowing the hackers to take over control of the machines, steal users data and make dangerous changes to the hosts.
As the HyperStack Trojan is often bundled with other advanced malware modules, it is likely that they will interact between themselves on the local machine. Many of these threats are delivered in encrypted form and a small module will decrypt and run them on the infected hosts. The dangerous factor about these type of viruses is that they can be configured to conduct a wide range of dangerous tasks, common ones are the following:
- Persistent Installation and Advanced Infection — Many similar computer viruses are programmed to reconfigure boot options and important configuration files. This will start virus together with the power-up of the computers, it may block access to the recovery boot options and etc.
- Files Theft — Through the installed virus instances, the hackers can steal any data that is found on the victim computers. This includes system information, application data, and important operating system files. Available data can also be modified or removed.
- System Changes — Many Trojans are programmed to conduct system changes. They can be to configuration files, the Windows Registry, or to some of the essential operating system values. Depending on the made changes this can lead to data loss, performance issues, and the inability to start certain services.
- Additional Malware Deployment — The HyperStack Trojan may be used as an intermediate payload carrier for other viruses: they can be cryptocurrency miners or even file-encrypting ransomware.
The made infections may make use of legitimate servers to hold covert information. A frequently used approach is to post commands to the local agents through collaborative platforms or online editing services, an example is Pastebin. Also, this malware can present itself in a worm form, meaning that the infected hosts will be recruited to a worldwide network. Their collective power can be harvested and used in further criminal attacks.
Given the fact that the intrusions were made against high-profile targets, it is possible that forthcoming campaigns can be set against other government, national and international organizations.
