KryptoCibule Trojan – Virus Infection Methods
The KryptoCibule Trojan is a recently discovered computer malware that has been unknown to this moment. It has an extensive component sequence which will be launched upon infection. As part of its main modules, the hackers behind it have included legitimate software such as Tor and the Transmission BitTorrent client. Other applications will be downloaded during the execution of the virus to serve specific needs. Multiple versions of the Trojan have been detected in detailed malware analysis, and the oldest samples have been found to have been in circulation since December 2018. Over the next several major versions, new functionality has been added, which has resulted in the creation of one very dangerous Trojan. From the virus samples tracking, the recent attack campaign’s main targets appear to be users in the Czech Republic and Slovakia.
It appears that the main distribution method is the use of virus-infected files. In most of the cases, the main virus carriers have been BitTorrent files — the hackers insert the virus code in files across popular legitimate and pirate data which is commonly downloaded from such file-sharing networks.
When the downloaded files are unpacked on a given computer, the resulting data will be ZIP packages that are masked as installers or executable files. The Torrent files will deploy several packages which will contain different parts of the combined KryptoCibule Trojan — packed.001 contains the malware, packed.002 is the installer of the carrier file. Both of these files are encrypted in order to remain hidden from the installed security programs.
The virus analysis shows that the virus will install the Transmission daemon torrent client on the local machine and receive commands from the remote attackers. Hardcoded account credentials are placed in the main engine; they will automatically log in to the servers and keep the connection. Using magnet URLs and direct HTTP requests, the KryptoCibule Trojan can retrieve other modules if that is commanded. Other possible file carriers include the following:
- Documents — The virus code can be placed in the macros that are carried in the common office file formats. This includes presentations, text documents, databases, and spreadsheets.
- Email Messages — Scripts that will install the Trojan can be attached or directly embedded in SPAM email messages which are prepared in bulk by the hackers.
- Direct Virus Files — The virus can be inserted as individual files include the likes of patches, updates, and add-ons for various programs or computer games.
We remind our readers that at any time the hackers can use fake or stolen identities to spread the data on online communities such as forums, chat rooms, social networks and etc.
KryptoCibule Trojan – Virus Capabilities
The KryptoCibule Trojan is categorized as an advanced threat which will start an advanced security bypass feature at the start of its execution. It will search for any installed security programs and attempt to disable or remove them. This is by identifying programs such as anti-virus programs, firewalls, intrusion detection systems and etc.
The main engine will be installed in a system files location in order to hide as an ordinary application. It will make itself very hard to discover as it will appear as a component of the Adobe Acrobat Reader program, one of the most popular applications for viewing PDF documents. Another dangerous function associated with the Trojan is its ability to install itself as persistent threat. It will guard itself against removal by the users by setting up a Scheduled Task and making sure that the application will be launched every time the computer is powered on.
One of the main goals of the KryptoCibule Trojan is to run a cryptocurrency miner which is a dangerous malware infection that is commonly carried by browser hijackers or run by hacker-controlled sites. They are designed to download and run complex mathematical tasks that will place a heavy toll on the performance of the computers. This is done by running them on the local computers, an action that will place an enormous load on the main hardware components: the CPU, GPU, hard disk space, Memory, and network speed. For every completed task the hackers will receive cryptocurrency assets as a reward.
During this operation system configuration values will be changed in order to create special firewall rules and disabling the Windows Defender functionality from scanning the processing threads. As part of the Trojan engine, the network traffic will be directed through the Tor anonymous network, an agent will be deployed alongside the Trojan.
The recent samples of the KryptoCibule Trojan have also been found to include a clipboard hijacker, a function which will monitor the saved data provided from the users. This can possibly be extended to the mouse movement as well. This is part of the malware’s wider information retrieval which also includes the ability to hijack files from the computers. The data will be transferred through the established tunnel.
Given the complexity of the Trojan we anticipate that further updates to it will be made available soon. At the moment there is no information about the hacking group who is behind its development and/or the associated attacks.
