The KBOT Trojan is a newly discovered malware which has been discovered in several large-scale campaigns across several regions and countries. This particular Trojan has an advanced infection sequence. When the virus engine is engaged in the first part of its sequence — to infect the target computers it will first process all EXE (executable) files on the accessed computer’s hard drives. However instead of stopping there it will also access other locations via the file manager — network shares and removable devices. This is very dangerous as this presents a very quick way for a single infection to impact a whole network in a relatively quick time. The security analysis shows that this is possible as the KBOT Trojan is programmed to interact with the operating system’s services.

According to the available information the KBOT Trojan primarily infects its targets through several main methods:

  • Internet Download — The users can acquire the virus samples via various methods. In most cases this includes phishing campaigns — the hacking groups will send out SPAM email messages and craft hacker-controlled sites which will impersonate well-known companies or services. As they are usually hosted on similar sounding domain names the victims can confuse themselves and interact with the faked content.
  • Local Network Infection — Already made infections from one of the computers in the local area network can lead to the virus deployment.
  • Direct Attacks — The hackers can use special toolkits in orde to discover and compromise found vulnerabilities and other types of security weaknesses.

KBOT Trojan Capabilities

The KBOT Trojan features advanced features and modules which will be run after the threat has been installed on a given computer. One of the first actions which will be done is to conceal itself in the system by interacting with the operating system through various methods — calling APIs, DLLs and editing configuration files. There are several consequences which can follow:

  • Security Applications Bypass — The engine can bypass or entirely remove installed security services and applications that can potentially block the virus. This includes the likes of anti-virus programs, sandbox environments, firewalls and etc.
  • Integrity Checks — The KBOT Trojan can inject its own DLLs in various other processes by hooking up to them and inserting itself in their configuration files.
  • System Changes — The main engine can also edit out existing configuration files and/or the Windows Registry. Such actions are commonly used to install the virus as a persistent threat — this will run the ransomware every time the computer is powered on.

Following the setup of the KBOT Trojan it will proceed with the usual activity — it can extract and inject information in web browsers — this is done by hooking up to the running processes and acquiring form data. The virus can automatically modify fields in web banking services and other opened web sites. This activity may not be visible to the users. The captured samples are compatible with the following applications: Google Chrome, Mozilla Firefox, Opera and the Yandex Browser.

The configuration used by the KBOT Trojan will also specify what to do following the web injection. The malware will follow the typical behavior by contacting a remote host using a secure connection which will be kept persistent for as long as possible. This will enable the remote attackers to take over control of the machines and/or install other threats when necessary.

During a detailed analysis of the acquired samples the specialists were able to extract a list of the possible commands:

  • DeleteFile — This will delete a specified file from the system.
  • UpdateFile — This will modify the contents of a given file with the supplied information.
  • UpdateInjects — This will update the injection configuration.
  • UpdateHosts — This will update the hosts file.
  • UpdateCore — This will pdate the main engine and the relevant configuration files.
  • Uninstall — This will remove the ransomware at request.
  • UpdateWormConfig — This action will update the file containing information about the relevant EXE file location.
  • UpdateBackconnectConfig — This will update the configuration file which will include a server list for reverse connections.
  • Load — This will load a designated file to the system. As a result spyware applications will be installed on the target computers.
