Team9 Trojan – Virus Infection Methods
The Team9 Trojan is a new malware which is developed by the criminal collective which is responsible for Trickbot. The analysis made on the collected samples indicate that it is a fairy recent creation, it is possible that parts of it have been taken from previous malware.
The public disclosure of the threat made by security experts was made available a few weeks ago, judging by the available data it is a fairy recent virus. Several iterations of it have been made over the years. This also includes different mechanisms for infection.
In one of the discovered samples the main delivery mechanism relied on the Windows BITS method before moving on to other strategies. Common variants include the following:
- Phishing Methods — The hackers can also employ various scam methods that are designed to manipulate the recipients into thinking that they are receiving legitimate notifications from a well-known service or company. These messages are commonly sent via email messages and/or hacker-controlled sites. To add authenticity they can be hosted on domain names that sound very similar to the ones that are impersonated.
- Infected Files Interaction — The Team9 Trojan code can be integrated in various data, the most common examples are macro-infected documents which are designed to enable the virus when popular types are opened: presentations, text documents, databases and spreadsheets. When application installers are considered by the hackers usually popular software is affected: creativity suites, productivity tools, office programs.
- Direct Web Infections and Carriers — Infections can be done by other malware which are already present in the target systems. This is also the case with exploits which are done by the hackers using automated platforms and tools targeting unpatched applications.
Team9 Trojan – Virus Capabilities
The Team9 Trojan contains an extensive list of modules which are integrated in it. One of the first actions which is started is the startup check — it verifies if it is the first installation of the threat. If a prior infection is detected a secondary one will not be made. When the malware engine is deployed it will add an entry into the Windows Registry making it run every time the computer is started. This mechanism is also called a persistent installation, other Trojans and versions of this malware can also edit out important parameters such as configuration files and boot options. In some cases the edits can render access to the recovery boot options impossible therefore preventing manual user recovery methods.
The Team9 Trojan is instituted in two versions (32/64-bit) and the appropriate build will be deployed to the victim systems. The next step involves the running of the actual remote control module — it will create a secure connection to a hacker-controlled site that allows the criminals to take over control of the hosts. The Trojan connection also allows for spying on the users and files theft.
In comparison with other malware the execution of the threat will not be instantaneous. This will prevent some of the virus detection signatures to locate the malware.
One of the most important steps taken by the virus will be to inject itself into system applications. In this case this are the Windows system services svchost, explorer and cmd. The system changes which are done by the main engine include the setting up of the threat as a Scheduled task to the Windows startup. A shortcut will also be added to the Startup folder and will hijack existing entries.
An analysis of the captured versions of the Team9 Trojan shows that the following commands are implemented:
- Delay Time Execution Adjustment — Using this command the criminals can adjust the time of delayed execution between the local client requests.
- Information Gathering — This will force the collection of sensitive information that is contained within the system. The included buffer will automatically start to collect information and send it to the hackers controllers.
- Downloading and Injection of Code — This will retrieve a file from a remote server and inject it into a running process using a special technique that will hide it.
- DLL File Running — This will retrieve a DLL files and execute it on the host computer.
- Batch File Running — This command will run a batch file on the infected computers./li>
- PowerShell Script Running — This allows the hackers to deliver a PowerShell script to the remote computers and run it on them.
- Tasks Termination — This will stop all running modules on a given computer.
- Files Theft — This option is used to hijack any data that is stored on the computer’s hard drive and accessible storage.
- Trojan Removal — This will remove all components of the Team9 Trojan.
Regarding the information collection module the made security analysis has revealed the type of information that is retrieved:
Operating system information, Operating system architecture, NETBIOS name of the infected host, Username of the infected user, Backdoor’s file path, Infected host time zone, , Processes list, Keyboard language, Antivirus name and installed applications, Infected host’s external IP, Shared drives, Shared drives in the domain, Trust domains, Infected host administrators, Domain admins.
Multiple domains are being used in the detected attack campaign all bearing names of legitimate sounding services. This also adds confusion to the visitors which can further manipulate the victims.
