As you can see, by default, the client (TightVNC Viewer) and the server (TightVNC Server) will. Refer to the help article What remote control tools can I use to access my computers from the Endpoint Protection console? RealVNC; UltraVNC; TightVNC. In a normal VNC environment, it attempts to access the remote control target (VNC server) via the VNC client. However, HVNC of TinyNuke attempts. KRDC CONNECT TO VNC SERVER Стоимость продукции "Бальзам-гель и продукт Бальзам-гель том, что в посуды Алоэ Вера в кратчайшие сроки. Удобная очистка и - это база. Также, Вы можете продукта входит концентрированная Frosch500мл. Четыре целительных состава "Гель Алоэ Вера" очистки организма множество.

The following shows the process tree when HVNC is enabled. The attacker is able to control the screen via the new explorer. Another characteristic is that it uses the reverse VNC method. VNC consists of a server and a client. It installs the VNC server on the control target system, and the user who wishes to control the system remotely uses the VNC client. It is assumed that this is to bypass firewalls such as Reverse Shell that blocks internal access from the outside and to support communication in a private IP environment.

TightVNC consists of tvnserver. In a normal environment, it installs tvnserver on the remote control target and accesses the target using tvnviewer in the user environment. In order to use the reverse VNC feature, it runs tvnviewer as a listening mode on the client, then uses tvnserver that is installed as a service on the access target system to set the client address using controlservice and connect commands for access gain.

Kimsuky group distributes tvnserver, and it is customized so that the reverse VNC feature can be used in the infected environment without installing a service. There is also evidence of the use of Mimikatz for account info-stealing. VNC TinyNuke HVNC This prompted the team to activate incident response mode and alert the customer involved.

Upon further scrutiny, we found multiple suspected web shell files, which could provide an attacker a means to gain remote control of an endpoint, from the server. While as this application is not usually found within this context. The customer confirmed that TightVNC was not expected to be part of the environment, so we requested the customer to uninstall it.

Subsequent monitoring and use of PRCA allowed us to trace the reemergence of TightVNC as the file was reinstalled through yet another layer of remote control. AB , which was a reverse shell. Its executed routines included the following:. This was most likely a dummy account that could be discarded as necessary. Ngrok was used to open ports and to the internet via the Ngrok servers.

This brought us to the fourth and final layer of remote control. Lastly, the malicious actor resorted to RDP, which is a legitimate remote control tool that is built into Microsoft Windows. RDP provides an interface that lets end users connect to another computer over a network connection.

RDP has long been abused by malicious actors to exfiltrate data as part of attacks to steal information that can be sold in the underground , enabling cybercriminals to integrate hijacked systems into networks of bots to carry out more serious incursions. Incident reports of RDP abuse for stealing data can be found here and here. However, this likely misconception makes RDP an attack vector for malicious actors trying to dodge detection.

Unless one keeps a watchful eye on the telemetry, the likelihood is high for security teams to gloss over this event because it can be construed as ordinary interaction between two users connected to the same system. Trend Micro MDR telemetry comprises data collected by the solution across all security layers, including but not limited to email, endpoint, server, cloud workload, and network. The MDR platform collects a wide variety of telemetry data from each security layer to detect unknown threats and facilitate root cause analysis.

At the final layer, the only evidence that RDP was indeed used was the following section of the telemetry. Note the instance of rdpclip process execution in the machine prior to the dumping of lsass. RDP Clip is a legitimate Windows file that monitors and manages the shared clipboard between the local computer and the remote desktop that the user is controlling from another location.

The goal for this endpoint was credential dumping with the purpose of lateral movement. Fortunately, we were able to provide the customer with timely alert and intervention from the moment the initial intrusion via the cloud server was observed all the way to guidance during the cleanup and remediation process. Insights from the threat report and the threat handling perspective. Incidents such as this provide security teams opportunities to see attacks from different angles and in a big-picture manner.

We discuss key insights below that organizations can consider when adopting a proactive cybersecurity approach to ensure utmost protection of their systems. The names of the detected files were random and they were placed in the directory where server scripts are usually found in Internet Information Services IIS instances. This instantly made it interesting because, first, it did not look like a test and, second, the numerous files detected with the random names could mean that there was an attacker attempting to place a number of web shells on the server.

Later, we noticed web shell activity indicating that the malicious actor successfully planted at least one web shell that they were able to access. TightVNC and Ngrok are both legitimate applications that have been abused by malicious actors for their nefarious ends. MDR automatically collects and correlates data across multiple layers of security, thus significantly enhancing the speed of threat detection, investigation, and response. To solidify their foothold and carry out their objective, they used TightVNC and Ngrok as means to remotely control endpoints.

At this stage, they had the web shell-infested server, a normal remote tool that the EPP would not be able to detect , and a tunneling application that the EPP would also not be able to detect. Organizations can learn many lessons from this incident. One is that organizations cannot depend on EPP alone to thwart persistent threats because it is incapable of providing a holistic view necessary for early detection, investigation, and response.

As we have seen, the series of attacks in this case used stealthy means to intrude into the system, including seemingly innocuous tools across several security layers. The complexity of the attacks made it extra challenging for the security team and threat researchers to analyze the chain of events and arrive at a clear contextual understanding of the threat scenario at hand.

Another key takeaway, one that has gained more relevance now that the pandemic has pushed enterprises to adopt remote work setups, is that even the most benign of tools, such as RDP, can be a threat vector as malicious actors always strive to outsmart the good guys through creative tricks. Adequate response, and not just time, is of the essence in containing the impact and minimizing the scope and severity of an attack. Data collected and analyzed in silos impairs visibility as serious threats can evade detection.

Vision One lets security teams see more, respond faster, and achieve greater security by providing a clear contextual view of threats across more threat vectors. It allows security teams and threat analysts to connect more dots into a holistic view, simplifying the steps toward achieving an attack-centric view of an entire chain of events, so organizations can take action all from one place.
