Introduction: Malicious use of 9hits on vulnerable docker hosts

During routine monitoring of our honeypot infrastructure, Cado Security Labs researchers (now part of Darktrace) observed a novel campaign targeting vulnerable Docker services. The campaign deploys two containers to the vulnerable instance - a regular XMRig miner, as well as the 9hits viewer application. This was the first documented case of malware deploying the 9hits application as a payload, based on available open-source intelligence at the time.

9hits [1] describes itself as “A Unique Web Traffic Solution”. It is a platform where members can buy credits, which can then be exchanged for traffic being generated on their website of choice. Members can also run the 9hits viewer app, which runs a headless chrome instance in order to visit websites requested by other members, in exchange for a cut of the credits.

The viewer app responsible for generating hits and credits is now being deployed by malware, in order to generate credits for the attacker.

Initial access

The containers are deployed on the vulnerable Docker host over the Internet by an attacker-controlled server. Cado Security have been unable to obtain a copy of the spreader, however can speculate that the attacker discovered the honeypot via a service like Shodan. This is because the attacker’s IP does not have any entries in common abuse databases, suggesting it is not actively scanning. It is also possible the attacker is using a separate server for scanning.

After discovery, the spreader uses the Docker API to deploy two containers:

Jan 08 16:44:27 docker.novalocal dockerd[1014]: time="2024-01-08T16:44:27.619512372Z" level=debug msg="Calling POST /v1.43/images/create?fromImage=minerboy%2FXMRig&tag=latest" 
Jan 08 16:44:38 docker.novalocal dockerd[1014]: time="2024-01-08T16:44:38.725291585Z" level=debug msg="Calling POST /v1.43/images/create?fromImage=9hitste%2Fapp&tag=latest" 

This can also be seen reflected in the network capture of the honeypot, originating from IP 27[.]36.82.56 (An IP in Foshan, China). The IP 43[.]163.195.252 (Tencent hosting in Japan) has also been observed in the past.

Network capture

Looking closer at the requests, we can observe a user agent of docker client:

User agent of docker client
Figure 3: User agent of docker client

Obviously, it is possible to clone a user agent and make it look like a Docker client. However, the order of API requests in the capture is identical to an actual instance of the Docker CLI. It is likely the attacker is using a script that sets the DOCKER_HOST variable and runs the regular CLI in order to compromise the server.  

The above API calls fetches off-the-shelf images from Dockerhub for the 9hits and XMRig software. This is a common attack vector for campaigns targeting Docker, where instead of fetching a bespoke image for their purposes they pull a generic image off Dockerhub (which will almost always be accessible) and leverage it for their needs.

In Cado’s investigations of campaigns targeting our honeypot, attackers often used a generic Alpine image and attach to it in order to break out of the container and run their malware on the host. In this case, the attacker makes no attempt to exit the container, and instead just runs the container with a predetermined argument.

Payload operation

As mentioned previously, the spreader invokes the Docker container with a custom command to kick start the infection. This command includes configuration and session identifiers.

Using memory forensics, the following processes being run by the 9hits container can be observed:

pid	  ppid	proc	cmd 
2379	2358	nh.sh	/bin/bash /nh.sh --token=c89f8b41d4972209ec497349cce7e840 --system-session --allow-crypto=no 
2406	2379	Xvfb	Xvfb :1 
2407	2379	9hits	/etc/9hitsv3-linux64/9hits --mode=exchange --current-hash=1704770235 --hide-browser=no --token=c89f8b41d4972209ec497349cce7e840 --allow-popups=yes --allow-adult=yes --allow-crypto=no --system-session --cache-del=200 --single-process --no-sandbox --no-zygote --auto-start 
2508	2455	9hbrowser	/etc/9hitsv3-linux64/browser/9hbrowser --nh-param=b2e931191f49d --ssid=<honeypot IP> 

In this case, the entry point for the container is the “ nh.sh ” script, which the attacker has added their session token to. This allows the 9hits app to authenticate with their servers and pull a list of sites to visit from them. Once the app has visited the site, the owner of the session token is awarded with a credit on the 9hits platform.

It appears that 9hits designed the session token system to work in untrusted contexts. It’s impossible to use the token for anything other than running the app to generate credits for the token owner, with the API and authentication tokens being a separate system. This allows the app to be run in illegitimate campaigns without the risk of the attacker's account being compromised.

9hits itself is based on headless Chrome, and as can be seen from the other processes, a browser instance is spawned to visit websites. The no sandbox, single process, and no zygote arguments are frequently passed to Chrome browsers running as root or in containers. There are a few other options that are set for this campaign, such as allowing it to visit adult sites, allowing it to visit sites that show popups, and configuring the cache duration. In addition, the actor behind this campaign has disabled the 9hits app’s ability to visit crypto related sites. The reason for this is unclear.

On the other container deployed by the attacker (XMRig), we can see it executes the following:

<code>1572	1552	XMRig	/app/XMRig -o byw.dscloud.me:3333 --randomx-1gb-pages --donate-level=0</code> 

The -o option specifies a mining pool to use. Most XMRig deployments will use a public pool and tell it the owner's wallet address, which can be frequently combined with the pool’s public data to see how many machines are mining for that address, along with the earnings of the owner. However, in this case it would appear that the mining pool is private, preventing access to statistics related to the campaign.

The dscloud domain is used by synology for dynamic DNS, where the synology server will keep the domain updated with the current IP of the attacker. Performing a lookup for this address at the time of writing, we can see it resolves to 27[.]36.82.56, the same IP that infected the honeypot in the first place.

Conclusion

The main impact of this campaign on compromised hosts is resource exhaustion, as the XMRig miner will use all available CPU resources it can while 9hits will use a large amount of bandwidth, memory, and what little CPU is left. The result of this is that legitimate workloads on infected servers will be unable to perform as expected. In addition, the campaign could be updated to leave a remote shell on the system, potentially causing a more serious breach. This has been seen before with mexals/diicot [2], a Romanian threat actor that maintained access to compromised servers using a malicious SSH key in addition to executing XMRig.

This campaign demonstrates that attackers are always looking for more strategies to make money from compromised hosts. It additionally shows that exposed Docker hosts are still a common entry vector for attackers. As Docker allows users to run arbitrary code, it is critical that it is kept secure to avoid your systems being used for malicious purposes.

The Problem of Re-defining Human Value in the Agentic Age

Default blog imageDefault blog image

Newsfeeds are constantly informing us about the rapid escalation of agentic AI systems. These systems move far beyond simple machine-based computations, and  the focused, defined and bounded assistance that most AI systems started out as.

The next evolution of AI will harness the agentic properties of orchestration, automation, and heightened value-chains in IT, taking on the burden of workflow management, not just workflow delivery.

In nearly all of these instances, promises are made such as ‘this will free up human time’ or ‘this will allow people to focus on higher-order strategy’. However that message is delivered, one thing is clear: in ceding the orchestration and management of work to increasingly sophisticated AI agents and agentic systems, human value will be elevated to a particular and specific layer: the ability to judge its outputs.  As AI takes on more tasks, humans should be able to focus on a higher level of governance; making sure the decisions that AI offers us are ethical, responsible and worthwhile.  

But there are two major problems with that approach.

This blog discusses the problem of how Agentic systems are re-shaping how we review information, where we fit in, and when we make decisions.  It also discusses the problem of how the increased flow of confident, generated information affects the way we make judgement.  This blog considers how human judgement needs to adapt, and how a behavioral defense approach – using techniques pioneered by Darktrace – can help us do that.

The challenge of knowing where human judgement belongs

As we confer more automated decision-making to agentic systems, it might look increasingly less like ‘granting permissions’, and more like ‘surrendering authority’.  

The judgement layer for AI-generated work is not a fixed boundary. We have become used to the idea of a ‘human in the loop’ (HITL) and, historically, relationships between humans and IT systems were reasonably clear and bounded.  Computer and software systems were programmed to carry out certain tasks or automated functions, and humans could control the gates and decision points where actions were undertaken. Even across highly complex computational workflows, human interaction was a controllable node within the process; we were able to configure and regulate. But in the agentic age, where that human interaction sits, and what it can influence shifts every time AI systems are granted autonomy.  

This leads us to the first problem: if humans are moving themselves (or are being moved) into the ‘judgement’ part of the value chain, exactly where and when do we exercise that judgement?  

Humans are no longer the sole shepherds of computer-based or software-controlled outputs.  We are at times at least one step further (and slower) behind the new agentic shepherds.  We might also be blind to what they are doing.  Not only might we be removed and blind to the actions of our AI shepherds, but with the challenge of unknown, unapproved AI systems operating beyond our control, humans might not even know that our work is being shepherded by an AI at all.  Simply put, with the advent of greater levels of autonomy and orchestration, humans are at risk of not even knowing where to apply our newly-extended powers of strategic judgement.

Shadow AI – the use of unapproved AI systems or processes – is a growing threat to the role of effective governance and oversight. Shadow AI isn't just the AI you can't see. Its the AI you already know about being used in an unapproved way. The ability to generate effective oversight of the AI systems you use (or that are used on your behalf) will be increasingly important to ensure that human judgement in the AI value chain is effective, and deliberately placed.

The problem of what makes good judgement

The second problem lies in how flawed human judgement can be.  Humans are historically, notoriously, and, sometimes dangerously, unreliable when it comes to exercising judgement.  Humans are prone to the worst kinds of bias, the seduction of malign influence, and the sometimes-overwhelming urge to succeed. AI has long had a known flaw of operating with sycophancy, providing outputs that tend to agree with or flatter the human user.  But as AI grows ever more effective, there is a risk of both hyper-enablement (where humans increasingly and knowingly enable AI despite potential harm), as well as the greater risk of suggestion. Both of these aspects could skew the newly-elevated input of human judgement.

Imagine a highly competent AI system that has just orchestrated and managed a dizzying array of processes and workflows.  The AI is designed to present the human decision-maker with recommendations; based on analysis, comparison and other programmed factors.  This is where the human judgement layer is enabled.  But what if that judgement is summarily diffused by an AI-based recommendation that emulates the decision, provides plausible but unattractive alternatives, then suggests (or, worse, directs) the human end-user to take a particular course of action.

The risk here is that you are given a recommendation, tailored to your preferences (which the AI has learned, or which you have divulged), and which appears to make perfect sense.  It appears to be a well-weighted recommendation, with sound arguments that tap into our inherent biases or inclinations so that a specific decision-path is followed. With the growth of agentic systems specifically designed to match user profiles (from Cowork agents to ‘digital twin’ models), the likelihood of agentic influence could badly skew human judgement or, at the least, devalue the proposition that humans are taking a higher-layer of strategic control over AI-based decisions.

If AI convincingly recommends something that may be problematic, it can be difficult to discern both accurate data, and the context required to make the right judgement.

Given the two problems described above, the job of exercising valuable human judgement in the agentic age can draw down to these two questions:

  • When should humans intervene in the agentic process?  
  • How can we make the best possible judgement calls?

What humans contribute that AI cannot

For all the flaws that make human judgement unreliable, people have the edge over even the most sophisticated and powerful AI systems when it comes to issues such as ethics and social context.  An AI system can, with startling granularity, rank the value of adopting a new business proposal: offering predictive metrics on costs, returns, market value, time-to-deliver operations, conformance with legal registers, etc.  But it can’t tell if the business proposal is ethically sound, or if the business venture will potentially affect groups outside of the analyzed proposal. It can’t tell you if the CEO has a ‘bad feeling’ about this effort.  It can’t tell you if this is the right thing to do.  

The ability to add social context, balance complex interpersonal dynamics, understand nuance, and to go beyond what seems economically reasonable is where human judgement can add value.  

Human judgement is difficult to encapsulate in metrics. And the way we train our development may need to adapt too. Rather than building up a gradual, experiential knowledge base, we should think about training the skill of judgement itself; especially for an agentic age.

How behavioral security strengthens AI governance

If this all feels like a vicious circle (‘I need AI help to make good judgements’ / ‘AI can twist what I need to judge’) it needn’t be. The key to this is having a defense-in-depth approach, with tools that can actually help.

This is precisely where behavioral security becomes important. The complex and nuanced way that humans exercise judgement is often rooted in our ability to recognize behavior that doesn't look right. We may not always be able to articulate it immediately, but we can often identify when an action, recommendation, or outcome feels inconsistent with the context around it. As AI systems take on more responsibility across the decision chain, preserving that ability to recognize meaningful deviations becomes increasingly important.

Darktrace’s / SECURE AI is designed to do exactly that. It applies behavioral security to AI ecosystems, helping organizations understand how people, AI tools, identities, and agents interact across the business. By learning the patterns of normal AI usage and surfacing activity that deviates from those patterns, it provides security teams with the context needed to investigate risk, understand unusual behavior, and make informed governance decisions. Rather than relying solely on predefined rules or assumptions, this behavioral understanding helps organizations distinguish between expected AI activity and behavior that warrants closer scrutiny.

This matters because we are already in an era of information overload. If humans are expected to elevate their value through strategic judgement, the ability to do this without being overwhelmed by data (good or bad) will be critical.  

We need the ability to discern when we're being misled by AI, and whether our judgement calls are being made on the basis of accurate, contextual information. Darktrace / SECURE AI provides that additional layer of defensive security for activity we cannot easily see. Whether it is suspected Shadow AI or skewed recommendations, the net result is a protected organization, where users can more effectively use AI to make positive judgements.

For those where that judgement is a critical skill (both individuals, as well as those working in security teams), improving our metacognition - the ability to understand information in a broader context - will supercharge the value of human judgement. When those judgements are grounded in context rather than assumptions we have better information to make sound decisions.

Conclusion

Human judgement is a skill that is honed over time and experience.  Darktrace’s / SECURE AI employs the same principles, but at machine-speed. Rather than influencing or directing, Darktrace / SECURE AI offers AI-enabled assurance; providing human-based judgement with the right context to make a balanced decision.  

What we judge can be valued by the legitimacy of its outputs. For AI, those outputs are valued on the speed and accuracy of the information provided.  Increasingly for humans, the value of our outputs will be based on the validity of our judgement, and how we justify our decisions in ways that engineer confidence.  

Humans often know more than we can express, while AI is prone to expressing more than it truly understands. Humans can bridge the context AI often fails to appreciate. When that judgement is supported by relevant, impartial AI systems, this is the future space where good AI governance will be exercised.

Darktrace Advances Incident Investigation and AI-Agent Security with OpenAI Daybreak Models

Default blog imageDefault blog image

Earlier this year, Darktrace joined OpenAI’s Daybreak Defense Network to explore how their cyber capabilities can be integrated within Darktrace products and services to transform how security teams move from signal to action.

At the heart of this work is Darktrace's behavioral understanding of customer environments and identification of complex security incidents, combined with OpenAI models that can add context to help explain why an incident matters and its potential impact on the business. By bringing these capabilities into defensive workflows security teams already use, the goal is to give defenders not just greater visibility, but the context and guidance they need to act with confidence.

Since joining the program, we've been working with OpenAI to explore how these capabilities can address specific security challenges for defenders.

The problem we're solving

Attackers continue to change how they operate, including by using AI to increase the speed and scale of some techniques. Security teams are already managing a large volume of alerts, and the question isn't just what's happening, but how it could affect the organization. Even when an incident is fully investigated and correlated, technical severity alone doesn't tell a security team how much it actually matters to the business. That same challenge extends to internal AI adoption. As organizations adopt more AI systems and agents, security teams need visibility into their behavior, access and activity, along with the broader business context needed to identify and investigate potential risk.

Darktrace's Adaptive AI™ builds a detailed, organization-specific picture of what's normal for each environment, and uses that picture to investigate threats and identify complex security activity across domains. OpenAI's models can build on Darktrace's correlated, technically prioritized incidents by adding context that can help defenders understand what may be at stake.

What we're building

Our work is focused on two areas: supporting security investigation and response, and helping defenders identify risky behavior across enterprise AI systems and agents.

The first aligns Darktrace's behavioral understanding with OpenAI models to support  security investigation and prioritization. Darktrace's Adaptive AI continuously learns the unique patterns of normal behavior within each customer it protects, creating a deep, organization-specific understanding of its digital estate. When unusual activity emerges, OpenAI's models can draw on that context to help analysts investigate the incident, understand its significance and assess potential business consequences — reducing the need to manually assemble context from fragmented signals.

Second, we are exploring how these capabilities can support AI-agent and runtime security through Darktrace / SECURE AI™. OpenAI’s Daybreak models can build on the detections and visibility Darktrace / SECURE AI provides, connecting signals across a customer's environment and help defenders identify potentially risky behavior involving AI systems and agents. Activity that might appear isolated can instead be connected with related signals, helping defenders investigate the broader context and determine appropriate remediation.

Darktrace brings deep cybersecurity expertise, an evolving understanding of each customer's environment, and AI-driven identification of threats across the digital estate. Through the Daybreak Defense Network, Darktrace is exploring how OpenAI models can augment those capabilities in defensive security workflows — supporting incident investigation and response and improving visibility into AI-agent and runtime risk.

These capabilities are still in development, and we're excited to continue building on this work.
