Since the beginning of the internet, we have seen a near, if not an exponential, surge of information sharing amongst users in cyberspace. Not long after, we saw how the emergence of social media ushered an access to public online platforms where other internet users worldwide could share, discuss, promote, and consume information, whether by deliberate choice or not.

These platforms, which are now wealthy in users, enabled the effectual sharing of a wide range of information and has facilitated the emergence of online communities, forums, webpages, and blogs - where everyone could create content and share it with other users leading to near infinite number of sources.

Public and private organisations have been able to leverage these platforms to communicate directly with the public, share relevant knowledge with their audiences, and expand users’ exposure to their organisation’s online presence – often by providing the users a direct link to websites and domains containing supplementary information on their organisations. However, there are some issues that organisations and users face when using such platforms.

Misinformation vs Disinformation

The ever-growing catalogue of informational sources and contributing users has introduced an old challenge with a more complex twist: distinguishing which information is truth and which is not. Two terms are used to describe inaccurate information – misinformation and disinformation.

Misinformation is “false information that is spread, regardless of whether there is intent or mislead”. For example, someone can read a compelling story on social media and share it with others without checking whether this story is, in fact, true.

During the COVID-19 pandemic, many people were rightfully concerned and anxious about their health, so they wanted to inform themselves as much as possible on the looming health risk. However, when they went looking for answers – they were overloaded with varying opinions and ‘fake facts’ that it became increasingly difficult to distinguish true facts from fiction.

Subsequently, at times a social media post - or two - that contained false information was shared by a friend, relative, or acquaintance who initially had good intentions in sharing what they had learned, but unfortunately, they were misinformed.

Disinformation instead means “deliberately misleading or biased information; manipulated narrative or facts; propaganda”, which can be interpreted as the intentional spreading of misinformation.

The main difference between misinformation and disinformation is the presence of clear intent in the latter. For example, during political conflict – or even wars – it is not uncommon for one, or both, opposing parties to broadcast news narratives to their own domestic audiences in the way that portrays them as either the righteous liberator or the unsuspecting victim.

Disinformation and Geopolitics

During turbulent times – such as (geo)political conflicts, national strife, digital revolutions, and pandemics – one can see the prevalence of massive disinformation campaigns being arranged by nation-state actors, independent threat actors and other ideologically driven actors. The likes of such campaigns are targeting businesses, governments, and individuals alike.

One of the most common channels used to spread disinformation would be social media platforms. In essence, any piece of information shared on social media can spread rapidly to all kinds of audiences across the globe. This is amplified by maliciously motivated actors’ use of “bots” to speed up the momentum of which disinformation is spread.

A bot is a “computer program that operates as an agent for a user or other program to stimulate a human activity. It is used to perform specific tasks repeatedly and autonomously. There is a plethora of these bots actively used to spread disinformation throughout the most popular social platforms including Facebook, Twitter and Instagram.

Impact of Disinformation on Organizations

When organisations are targeted by disinformation campaigns, malicious actors aim to leverage the discord and uncertainty on topics that are shrouded in controversy. Malicious actors like online scammers aim to exploit this induced discord by e.g., creating phishing emails that are more compelling to recipients – who are just trying to navigate between what is real and not real.

For example, a campaign stating that data held by a big telecommunication company was breached is used to craft emails in which scammers would prompt the recipients to check whether their personal data was also affected by this ‘breach’.

Regardless of whether this information is correct or not, the flux of news floating around the internet makes it increasingly difficult for a person to decide whether this information is accurate.

In parallel, the recipient may be experiencing feelings of anxiety and uncertainty regarding the breach – and the news about the breach – which often affects the recipients' decision to immediately react to new information on the topic. Since scammers use domains that are carefully crafted to seem legitimate to an untrained eye – e.g., domains containing near uncanny resemblance to the official organisation’s domain – it further increases the recipient’s susceptibility to trusting dubious sources. Thus, increasing the likelihood that recipients of phishing emails would be more compelled to e.g., click on a link attached to an email to verify whether their data was also leaked, or not.

The Future of Disinformation

Organisations who are already dealing with the social strains created by disinformation campaigns are now facing an additional risk: their audiences may be more susceptible to phishing campaigns in times of widespread uncertainty. To make a convincing phishing campaign, malign actors often use compromised domains, or attempt to mimic legitimate domains through a method called ‘typo squatting’.

Typo squatting is the act of registering domains with intentionally misspelled names of popular or official web presences and often filling these with untrustworthy content – to give their victims a false sense of legitimacy surrounding the source.

Once this false sense of legitimacy has been established between the attacker’s source and the victim’s susceptibility in trusting that source, it will be nearly entirely up to the victim to avoid being misled. Consequently, this means the attack surface of an organisation is growing as fast as disinformation and false domains can be created and shared to its audience.

Combatting Disinformation with Attack Surface Management

Organisations trying to protect their audiences from being misled by false domains will need get better visibility on domains associated with their brand. A brand-centric approach to discovering domains can shine light on:

  • The state of existing domains that are currently managed by your organisation – if they are being well maintained and properly secured.
  • The influx of ‘new’ domains that are attempting to impersonate your organisation’s brand.

Visibility on these types of domains and how your audience often interact with these domains enables an organisation to be more vigilant and responsive to the malign actors attempting to manipulate, hijack or impersonate your brand. Since an organisation’s brand pervades all sorts of publicly accessible assets – like domains – it has become of significant importance to include them in your organisation’s attack surface management regimen. Utilising a brand-centric approach to attack surface management will give your organisation a clearer view of your attack surface from a reputation risk perspective.

An attack surface management solution bolstered by such an approach will help your organisation’s security team to efficiently determine which domains – or other external facing digital assets – are posing a risk to your audience and reputation. It will help remove the repetitive work needed to identify these domains (and other assets), detect the risks associated with them, and help you manage any changes or actions required to protect both your audience and your organisation.

Why Kubernetes Security Needs A Behavioral Approach

Man at computerDefault blog imageDefault blog image

Kubernetes has become a foundational technology for modern cloud-native infrastructure. It can orchestrate everything from customer-facing applications to data pipelines and, increasingly, AI workloads. This is due to the highly scalable nature of Kubernetes, making it cost efficient and reliable.

Gartner projects that by 2028, 95% of new AI deployments will run on Kubernetes, up from less than 30% today1. However, the same qualities that make Kubernetes powerful also make it uniquely challenging to secure, leaving many organizations with limited visibility into their clusters. This lack of visibility increases risk - it’s difficult to secure what you can’t see.

However, this risk is often looked at as purely a posture management challenge. While Cloud Security Posture Management (CSPM) solutions can tell you how a cluster should be configured, they don’t tell you what it is doing in real time. This requires runtime behavioral monitoring of clusters to detect active threats.

Yet existing approaches to securing Kubernetes by most Cloud Detection and Response (CDR) and Network Detection and Response (NDR) vendors often have limited coverage or require a third-party integration to forward traffic and metadata. This means that capabilities can be limited and detections can lack the context of the wider environment, which slows down triage, investigation and response.

Why Kubernetes is hard to secure

Traditional security tooling was built for persistent, long-term infrastructure such as servers and virtual machines with fixed identities that last months or years. Some elements of Kubernetes environments can have a much shorter lifespan, breaking many assumptions those tools rely on:

  1. Increased complexity
    1. Kubernetes environments can be complex in comparison to traditional infrastructure, with many different elements to consider such as nodes, clusters, containers, pods and the workloads themselves.
  2. Ephemeral by design
    1. Kubernetes pods can spin up and terminate in seconds. A container that was compromised may no longer exist by the time a deeper investigation is required, leaving no artifact to analyze. This poses a unique challenge for security operations.
  3. Weaker workload boundaries
    1. Kubernetes containers use lightweight, shared-kernel isolation rather than separate virtual machines, improving efficiency but reducing separation between workloads and the host. As a result, a compromised container may have a greater potential impact on the node and neighboring workloads than a compromised virtual machine (VM).2
    2. Recent vulnerabilities have shown that threat actors can escape a container and gain access to the underlying host.3, 4
  4. Everything is API-driven
    1. Dozens or hundreds of microservices communicate over internal APIs, and the Kubernetes control plane itself is an API. This creates a large and dynamic attack surface, making it difficult to distinguish legitimate activity from malicious behavior.
    2. Without identity-aware runtime visibility, threat actors can move laterally between pods and exploit misconfigured role-based access controls (RBAC) with little chance of detection.

Rising to the challenge of securing Kubernetes

With the release of Darktrace 7.2, Darktrace / HYBRID NETWORK can extend behavioral security into Kubernetes, delivering visibility, detection and response capabilities across runtime activity. Darktrace addresses the challenges of securing Kubernetes environments in several ways.

Behavioral detection, not static rules

Many Kubernetes runtime tools rely on predefined rules and signatures - a fixed list of “bad” behaviors to match against. That approach struggles with novel attacks and generates noise at scale. Darktrace takes a different approach: our Adaptive AI builds a Unique Behavioral Profile for each organization from the ground up, learning the normal behavior of every workload, node and identity in your cluster. It then uses this understanding to detect meaningful deviations from expected behavior, which serves as the basis for surfacing suspicious and malicious activity.  

A pod reaching out to an unfamiliar destination, an unexpected executable launching inside a workload, or an identity performing an action it has never performed, all surface as anomalies without anyone having to write a rule in advance.

Darktrace surfaces unexpected Kubernetes activity that does not align with an organization’s Unique Behavioral Profile

‍

Visibility across the network, the process, and the control plane

Darktrace monitors Kubernetes at three levels that together provide comprehensive runtime visibility:

  1. Network-layer
    1. Traffic between pods, across nodes and out to the internet. This helps to detect lateral movement and unusual connectivity, whether internal or external.
  2. Process-layer
    1. What is executing inside your containers. If a process reads a sensitive credential file or spawns an unexpected shell inside a production pod, Darktrace can identify that activity and use it as context for further detections.
  3. Control plane
    1. Activity against the Kubernetes API itself: someone executes a command in a running pod, RBAC changes, or unusual administrative actions. Many high-impact security events involve the control plane, an area that is often less visible to solutions that only analyze or scan network-layer telemetry.

Misconfiguration and vulnerability awareness

Runtime detection is strongest when combined with posture and exposure management. Darktrace surfaces risky pod configurations, such as privileged containers, host networking, and over-permissive service accounts as workloads are deployed, and links CVEs from images to the workloads running them. Security teams can go beyond simply knowing that a vulnerability exists and see exactly where it is in the cluster. When combined with behavior-based detections, this provides invaluable context that can help prioritize incidents and proactively identify areas that need further attention. For example, anomalous workload behavior on its own might not be very interesting to a security team at first, but if that same workload is known to host sensitive data, is known to have critical vulnerabilities associated with it, or is publicly accessible, then this narrative becomes much more suspicious and demanding of their attention.

Darktrace highlights Kubernetes misconfigurations such as privileged containers, host networking, and missing security controls, helping teams prioritize runtime alerts with valuable exposure and risk context

‍

Response, tailored to Kubernetes

Detection is most effective when paired with response. Darktrace can take precise actions on Kubernetes workloads, including blocking a malicious connection at the pod level, helping to safely contain threats while security teams investigate. Response actions can be taken fully autonomously or via a human-in-the-loop process, which is completely configurable depending on the desired level of autonomy and scope. Darktrace is expanding the number of Kubernetes-native response actions to give customers even more flexibility when containing threats.

Forensics that survive the workload

Because containers are so short-lived, evidence disappears fast and this can make it very difficult to answer questions related to the initial detections. Darktrace solves this with Forensic Acquisition & Investigation capabilities that extend to Kubernetes containers, allowing investigations to be triggered manually by an analyst, or automatically from an alert, preserving evidence before the workload is gone.

For incident responders, this addresses a key challenge in container security: being able to answer “what actually happened?” after an ephemeral workload has vanished.

One platform, not another silo

Kubernetes doesn't exist in isolation, and neither should its security. Darktrace correlates cluster activity with the surrounding cloud environment, including AWS, Azure and GCP identities, network activity and cloud assets, allowing analysts to pivot between a Kubernetes workload and its wider context. A single anomalous action can be traced from the control plane to the pod, and from the pod to the cloud identity behind it, all within a single investigation workflow. This can also include alerts from other areas of hybrid infrastructure or third-party sources where relevant, adding more context to investigations and speeding up workflows for human analysts.

Built to deploy easily

Operational complexity can be a barrier to security adoption. Darktrace / HYBRID NETWORK for Kubernetes installs with a single command, and for teams that manage their infrastructure as code, it supports raw manifests so the deployment can live in a Git repository and be managed through existing GitOps workflows. The same deployment approach works across Kubernetes environments in AWS, Azure, Google Cloud, and on-premises infrastructure. Early adopters of Darktrace’s Kubernetes capabilities have highlighted the simplicity of deployment and time to value.

Darktrace can deploy across your Kubernetes environment and wider hybrid infrastructure, while also providing visibility into Kubernetes deployment structure and status

Next steps

Kubernetes environments are dynamic, ephemeral and API-driven in ways that challenge traditional security tooling. With Kubernetes usage increasing due to widespread AI adoption, it is essential to secure Kubernetes environments as part of securing what AI can do. Darktrace / HYBRID NETWORK addresses these challenges by learning normal behavior in Kubernetes environments across network, process and control-plane layers, identifying meaningful threats and enabling targeted response. Combined with the context of wider hybrid infrastructure and forensic investigation capabilities, Darktrace provides visibility into both emerging threats and active incidents.

CikaBika Bot: Inside a Discord RAT

Default blog imageDefault blog image

‍

Key Takeaways

·      Darktrace malware researchers have found an ongoing malware campaign using a document-themed lure containing a malicious LNK file and a PDF with an embedded payload.

·      The Nim based loader deploys a Rust-based remote access trojan (RAT), using a UAC bypass and DLL search-order hijacking technique targeting Microsoft Edge.

·      The RAT uses Discord for C2, creating dedicated channels to manage infected devices and execute commands.

·      CikaBika Bot supports system reconnaissance, remote command execution, screenshot capture, and file transfers.

‍

Introduction

In a threat landscape where attackers continue to rely on social engineering techniques to deliver malware, legitimate services are increasingly being abused to support malicious operations. Communications platforms like Discord can provide attackers with a ready-made channel for command-and-control (C2), allowing them to manage compromised devices without establishing dedicated infrastructure.

Malware researchers at Darktrace have identified a campaign distributing CikaBika, a Rust-based RAT that uses Discord for C2. The infection chain begins with a disk image and a malicious Windows shortcut. A Nim loader extracts the final payload and attempts to plant it in Microsoft Edge’s installation directory using a PowerShell UAC bypass. Once running, the RAT collects host information, registers the device with Discord, and accepts commands through a dedicated channel.

Technical Analysis

‍

Figure 1: Contents of Proposition_Projet.img.

‍

Initial access and PDF payload

The malware is packaged within a disk image named Proposition_Projet.img. Inside are a PDF titled “Presentation_Generale.pdf.pdf” and a Windows shortcut (LNK) disguised as a Word document, “Proposition_Projet_Personnalisable.docx”. The delivery method has not been confirmed; however, the filenames and document-themed lure are consistent with a phishing campaign.

‍

Figure 2: PowerShell command embedded in the malicious shortcut.


Opening the shortcut launches a hidden PowerShell process while displaying the PDF as a decoy. The French-language document explains how to produce a written summary or contraction of a text. In the background, PowerShell reads the PDF as bytes and uses the value at offset 239 (0x20) as an XOR key to decode an embedded executable. The resulting payload is written to %TEMP%\IfyuUapz.txt and executed using cmd /c.

Nim loader and UAC bypass

“IfyuUapz.txt” is a Nim-based loader that contains two Base64-encoded blobs: a Rust dynamic-link library (DLL)  and a PowerShell deployment script. Both are decoded and written to temporary files, referenced to within the loader as “dllFile” and “copyPs1”. The loader runs the script through a hidden PowerShell process using an encoded command, then attempts to load the DLL using Nim’s loadLib function. If loading fails, it invokes regsvr32.exe and retries.

Figure 3: Silent DLL deployer.

The PowerShell component is responsible for moving the DLL to C:\Program Files (x86)\Microsoft\Edge\Application\dbghelp.dll. It first copies the DLL to C:\Windows\Temp\dbghelp.tmp, then modifies HKCU\Software\Classes\ms-settings\shell\open\command so that launching computerdefaults.exe can trigger a command to move the staged DLL into the protected Edge directory. This is an attempt to bypass User Account Control (UAC), which depends on the target’s Windows configuration.

The script also compiles a small C# helper that calls ShowWindow to hide windows associated with Windows Settings and ApplicationFrameHost. It launches the bypass helper three times, checks for the presence of the destination DLL, and attempts to delete the temporary scripts, intermediate DLL, and associated registry changes.

‍

Figure 4: Legitimate msedge.exe function to load the legitimate dbghelp.dll.

‍

The legitimate msedge.exe has a delay-loaded dependency on dbghelp.dll, and the malicious DLL exports a subset of the functions associated with Microsoft’s debugging library. The attacker appears to be exploiting this dependency through DLL search-order hijacking. However, it does not export every function in Edge’s delay-import table, meaning its compatibility with the host is incomplete. The observed code establishes the intended sideloading route, rather than proving that Edge successfully loaded the planted DLL.

‍

Rust RAT payload

Figure 5: Discord configuration within the RAT.

The malicious dbghelp.dll (IfyuUapz.txt) is a Rust-based RAT. At startup, the RAT registers the compromised device with Discord and begins collecting information about the host. Its reconnaissance routine gathers system details, runs tasklist to enumerate processes, executes ipconfig to obtain network configuration, and attempts to take a screenshot. The resulting artifacts include tasklist_startup.txt, network_info.txt, and screenshot.png.

Figure 6: Network configuration notification in Discord channel.

‍

Figure 7: Network configuration output from network_info.txt.

‍

Discord C2

The RAT uses Discord channels to send commands and report results. The operator can send commands to the device’s channel and receive the resulting output in the same conversation. This gives the attacker an interactive command interface without having to operate and maintain a dedicated C2 server.

Figure 8: Commands available in Discord.

The command set includes !shell for remote command execution; !sysinfo and !info for host details; !isOn for status checks; !tasklist and !ps for process enumeration; and !kill for process termination. File-transfer commands include !upload and !download. Additional strings and command handlers reference screenshots (!src), camera access (!camera), streaming (!stream), and broadcasting (!broadcast).

‍

Figure 9: Device registration in Discord.

During device registration, the malware retrieves the victim’s public IP address using ipify.com. The registration message records the device ID, hostname, registration time, private and public IP addresses, status, uptime, and the Discord channel assigned to that device.

Operator activity and exfiltration

Figure 10: Powershell commands sent through Discord to exfiltrate data.

Once a device is registered, the attacker can issue commands through its dedicated Discord channel. In the observed activity, the attacker compressed a directory into a ZIP and exfiltrated it using ngrok.

Figure 11: Download command to retrieve a document from the target.

‍

The operator can also use !download to retrieve files from target. The example above displays a request for a specific document on the victim’s desktop. The requested file is then returned through the device’s Discord channel, giving the attacker a direct way to store and access selected data.

Conclusion

CikaBika Bot demonstrates how attackers continue to rely on social engineering techniques to deliver malware. Although the initial distribution method has not been confirmed, the use of a disk image containing a shortcut disguised as a Word document, alongside a legitimate-looking PDF, suggests the campaign was designed for phishing.

While Nim is less commonly encountered than C in Windows malware, it has increasingly appeared in malicious tooling. In this case, Nim is used to unpack and deploy a Rust-based RAT, adding another layer to the infection chain.

Once installed, CikaBika Bot uses Discord as its C2 platform, allowing the attacker to manage compromised devices, execute commands, and retrieve files without maintaining dedicated C2 infrastructure. The observed use of Discord channels for individual victims, alongside additional data exfiltration through ngrok, shows how legitimate services can be repurposed to support malicious operations.
