Dark Nexus Trojan — Overview

The Dark Nexus Trojan is a dangerous IoT-designed malware that is currently being spread against networks on a global scale. Researchers are tracking its movements as it infects numerous computers and devices in a very active attack campaign. There is no no information about the hackers who are behind it at this moment however it is speculated that they are very experienced.

The main code of the threat appears to have borrowed some of the ideas and mechanisms of well-known IoT botnets such as Mirai and Qbot. A distinct and very dangerous characteristic of Dark Nexus is that it is cross-compiled to run on 12 different platform architectures. They range from small embedded devices to personal computers and consumer laptops. This means that practically all major types of devices that can be found on a local network can be affected by it. It is also continuously developed meaning that the developers are constantly improving it by adding new features in incremental updates. The first attacks were detected back in December last year and in just a few months the Dark Nexus Trojan and Botnet client were updated with over 30 interim patches. Through them the developers added in new features and expanded on already existing ones.

At this moment not a lot of devices have been hijacked however given the enormous feature list and capabilities provided by it we assume that a large-scale attack campaign would soon follow. According to the security research the developer of Dark Nexus is responsible for other malware including an older botnet which is based on Qbot. It is very possible that the Dark Nexus Trojan is being sold on underground hacking communities for a price. This will also allow for the offering of customization options as well.

Dark Nexus Trojan — Advanced Functionality

Botnet Trojan attacks like Dark Nexus are done primarily via direct network attacks which are designed to look for weaknesses in a given computer or network and exploit them with the intention of installing a copy of the malware onto the affected device. There are several advanced techniques which are incorporated into the attack model associated with Dark Nexus. This includes the disguising of the botnet traffic as ordinary web browser activity. Proxies have also been used to hide the actual incoming traffic, there is speculation that they might be rented to the botnet operators. One of the main techniques used to infect computers will be to use a Telnet credentials attack which uses the widely used remote control protocol. At the moment the majority of attacks are against IoT networks in South Korea. When a vulnerable host is detected it will be automatically exploited and the result reported back to the hackers. A debugging module is also built which will monitor the status of the infected devices.

Each of the infected computers with the Dark Nexus Trojan will include a flexible behavior sequence that will dynamically download the main engine. his means that the Trojan is divided in several parts – a small initial loader, a main engine and extensions. When the whole of the Dark Nexus Trojan is installed on a given computer the typical function of allowing the criminals to take over control of the hosts, steal data and etc. The new releases of the threat also feature a persistent installation which means that the associated actions will be executed every time the computer is started.

A lot of different malware actions can be called by the hackers on request or depending on the local system conditions:

  • Boot Option Changes — The main engine can opt to modify the boot options of the affected machines so that recovery options will be disabled.
  • Device Configuration Changes — Depending on the chosen platform the Dark Nexus Trojan can modify important settings of the system. This can lead to overall system instability or other issues.
  • Additional Malware Deployment — The Dark Nexus Trojan can be used to deploy other threats to the machines. Popular options include ransomware and cryptocurrency miners among others.
