Kimsuky Trojan – Virus Infection Methods

The Kimsuky Trojan is a newly discovered malware module that appears to originate from North Korea hackers. It is probably the work of a state-sponsored group, however concrete evidence is still not found. From the analysis of the captured samples, the researchers note that it is possible that the criminal collective has been active since as early as 2012. The experts from Cybereason have published an extensive analysis giving further information about the capabilities of this new malware.

What we know is that it has been previously known under other names as well: Black Banshee and Thalium. Over the years different tactics and modules have been added to intrude onto the target computers. The American FBI and DOD released a memo giving further information about the captured versions of this threat.

To obtain access to the target systems the hackers use mainly manipulative tactics. The hackers will attempt to manipulate system owners into opening up crafted email messages that are sent to them. By opening them and interacting with the content, the virus will be deployed to the target system and automatically start its commands. Other social engineering can be the following:

  • Fake Landing Pages — The criminals can create counterfeit pages and sites of famous services and companies. The usual mechanisms through which this is done is the use of similar-sounding domain names, this can fool the recipients into thinking that they have accessed the legitimate page, but in fact they have mistyped it. To make them appear as safe and useful, the hackers may insert stolen content and design as well.
  • Intrusive Advertising — Links to these hacker-created sites can be easily sent over ad networks and other portals that are being operated by criminals.
  • Redirects — The use of web browser hijackers and associated redirect code can be used to deliver this particular malware to the target computers.

Other tactics can be used by the hackers in forthcoming attacks. The Kimsuky Trojan has been found to use several clever social manipulation tactics. The hackers appear to have targeted experts in different fields and send out specific template-based messages. For instance, journalists can receive interview prompts, while others can receive academic articles or important system notifications. The email messages will contain a backdoor loader that will lead to the deployment of the Trojan.

Kimsuky Trojan – Virus Capabilities

At the start of the infection, the virus will start a combination of several actions: the use of a loader component called BabyShark and a sequence of commands that are to be executed by the operating system. It is very likely that this is done in accordance to the guidelines observed by most hacking groups to conduct a security bypass procedure. This is the scanning of the local computers in search of applications that can block viruses from running properly. This includes anti-virus programs, firewalls, intrusion detection systems, and etc.

Many malware of this type will also be programmed to gather valuable information: the hijacked information can be both personal user’s information or operating system data. The collected may be used to conduct other crimes such as financial abuse, identity theft, and etc. Usually, by using the data obtained from the systems the hackers can use another module to generate a unique identity of each individual computer. Some of the areas that are accessible by this particular Trojan includes application data (including web browsers), the Windows Credential Manager, email client programs, office software, or remote desktop clients. As part of this malware, other components can be downloaded and run, depending on the individual hacking strategy.

One of the main modules which are run by the criminals is the running of the Trojan module which will establish a persistent and secure connection to a hacker-controlled server. It is not known whether or not other modules can be downloaded and run by hackers. Important changes to the system can also be Windows Registry — existing values can be edited or the malware can create new ones for itself. This can lead to issues such as performance issues, data loss, and the inability to run certain services.

During the running of the main Trojan threat, the security analysis has discovered that the virus will also run a keylogger instance — a small program that will hijack the keyboard input and mouse movement of the victim users. Some of the dangerous modules and capabilities that are part of the infection module include anti-forensics, anti-virus evasion techniques, backdating of the executables, and etc.
