BazarLoader Trojan – Virus Infection Methods
The BazarLoader Trojan is being distributed through an elaborate method abusing the popular BaseCamp online service, a platform service for project management. Last week a worldwide attack using this mechanism was detected in a worldwide campaign orchestrated by an unknown hacking group. The criminals take advantage of the documents creation utility which is part of the service.
The method of infections relies on the creation of links and file attachments of virus data in documents that are created on BaseCamp. As this is one of the most popular collaborative platforms, it is often seen as a trusted website and is not filtered by firewalls. Links to the BaseCamp documents can be distributed using popular strategies. Most of them will rely on the use of manipulative techniques — the criminals will post the links in content that masks itself as safe and useful. The list of possible sources usually includes popular services and companies, examples are notifications, web pages, letters, documents, and etc. Many hacking groups will also choose to post on popular online services and communities like social networks, chat rooms, and forums.
As the identity of the criminal group is not known at the moment, we suspect that they are an experienced collective. For this reason, other infection techniques can be considered in future campaigns. Examples include the use of other virus carriers — through their own execution sequence the BazarLoader Trojan will be deployed to the victim computers. Many hackers will also rely on the use web scripts that can redirect or directly open the BaseCamp pages.
BazarLoader Trojan – Virus Capabilities
BazarLoader Trojan samples have been captured in the ongoing attack campaigns. This allows for an in-depth look into the features and capabilities of the threat as it is found on an infected computer. The analysis shows that once the virus is executed on the host machine, it will immediately start a complex execution pattern. It will interact directly with the Windows command line to start processes of its own and execute scripts that will modify the system settings and important files.
The hijacked files appear to be digitally signed with a strong called Best Fud OOO, which might signal a code name used by the hacking group. This also might be used to confuse the operating system into thinking that this is a legitimate and safe file that is loaded into memory. The first process that is started and controlled by the criminals is designed to execute apps for hidden code execution — any further commands that are run will bypass the operating system security features.
A major part of the BazarLoader Trojan operations is the launching of the data gathering procedure. It can be instructed to gather different types of information, all relating to data that can be stolen by hackers. It may be a report of the installed hardware components, individual computer operating system values, and personal user data. The use of such information can lead to the generation of a unique identifier for each affected host. By having access to personal user’s data, hackers can use it for blackmail or identity theft purposes. Applications data is also hijacked from the installed web browsers — it can serve as an additional source of personal users information.
As a Trojan malware, the malware will start a remote control operation — the engine establishes a secure connection to a hacker-controlled server. This allows the hackers to fully take over control of the victim machines, hijack any available files, and spy on the victims in real-time.
To a large extent the Trojan can lead to numerous system changes, they will depend on the hacker instructions, in typical cases this includes the following:
- Boot Changes — The BazarLoader Trojan may be installed as a persistent threat, thereby starting autoamtically when the computer is powered on. This step may also block access to recovery options.
- Windows Registry Modifications — The malicious engine may modify existing values or create new ones according to the designated hacker instructions.
- Data Manipulation — Files found on the compromised machines can be removed, this includes backups and shadow volume copies. This makes recovery much more difficult.
Detected instances should be removed at once to prevent further damage to the compromised machines.
