The Oblique Trojan is a new malware which currently targets victims located in the South East Asia region. It is known that it is the work of an experienced hacking group which appears to be specialized against high-profile diplomatic and government targets.

This particular campaign is being distributed to the intended victims using infected documents that contain dangerous macros. This means that the Trojan will be delivered when the users interact with them. When they are opened a prompt will be spawned asking the users to enable the scripts to correctly view the documents. However this will execute the first stage of the Oblique Trojan installation process. Instead of following the common tactics used by most other related threats the hackers are using an alternative approach — when the files are opened a password will be requested to be entered. It will be supplied in the site, email or other delivery method throuh which the files are spread.

At this time most of the malware files are sent via phishing email messages — the hackers are sending messages which use template titles and contents, examples are the following: “Company-Terms.doc, “DOT_JD_GM.doc” and other similar terms. WHen the corrrect password is entered in the document this will trigger a built-in Visual Basic Script that will extract a dropper which will downlod the Trojan.

The dropper will also ensure that a persistent installation will be achieved — the Oblique Trojan will be deployed to the host computers in way which will ensure that it will always run and get started every time the computer is powered on.

Before the other modules are run the Oblique Trojan whether or not the username or computer name is not listed in the built-in blacklist — this ensures that certain networks are not to be processed. When the main Trojan starts it will also interact with the Windows Mount Manager which will list all connected hard disk drives, network shares and removable devices. This action will allow the hacker operators to hijack sensitive data not only from the contaminated computer, but also from the available network.

The Oblique Trojan can be further extended with other functionality as the hacking group extends its attack campaign. We will continue to monitor the infections and update this article accordingly.
