Between June 2021 and June 2022, crypto-currency platforms around the world lost an estimated 44 billion USD to cyber criminals, whose modus operandi range from stealing passwords and account recovery phrases, to cryptojacking and directly targeting crypto-currency transactions.
There has been a recent rise in cases of cyber criminals’ using information stealer malware to gather and exfiltrate sensitive crypto-currency wallet details, ultimately leading to the theft of significant sums of digital currency. Having an autonomous decision maker able to detect and respond to potential compromises is crucial to safeguard crypto wallets and transactions against would-be attackers.
In late 2022, Darktrace observed several threat actors employing a novel attack method to target crypto-currency users across its customer base, specifically the latest version of the Laplas Clipper malware. Using Self-Learning AI, Darktrace DETECT/Network™ and Darktrace RESPOND/Network™ were able to uncover and mitigate Laplas Clipper activity and intervene to prevent the theft of large sums of digital currency.
Laplas Clipper Background
Laplas Clipper is a variant of information stealing malware which operates by diverting crypto-currency transactions from victims’ crypto wallets into the wallets of threat actors [1]. Laplas Clipper is a Malware-as-a-Service (MaaS) offering available for purchase and use by a variety of threat actors. It has been observed in the wild since October 2022, when 180 samples were identified and linked with another malware strain, namely SmokeLoader [2]. This loader has itself been observed since at least 2011 and acts as a delivery mechanism for popular malware strains [3].
SmokeLoader is typically distributed via malicious attachments sent in spam emails or targeted phishing campaigns but can also be downloaded directly by users from file hosting pages or spoofed websites. SmokeLoader is known to specifically deliver Laplas Clipper onto compromised devices via a BatLoader script downloaded as a Microsoft Word document or a PDF file attached to a phishing email. These examples of social engineering are relatively low effort methods intended to convince users to download the malware, which subsequently injects malicious code into the explorer.exe process and downloads Laplas Clipper.
Laplas Clipper activity observed across Darktrace’s customer base generally began with SmokeLoader making HTTP GET requests to Laplas Clipper command and control (C2) infrastructure. Once downloaded, the clipper loads a ‘build[.]exe’ module and begins monitoring the victim’s clipboard for crypto-currency wallet addresses. If a wallet address is identified, the infected device connects to a server associated with Laplas Clipper and downloads wallet addresses belonging to the threat actor. The actor’s addresses are typically spoofed to appear similar to those they replace in order to evade detection. The malware continues to update clipboard activity and replaces the user’s wallet addresses with a spoofed address each time one is copied for a for crypto-currency transactions.
Darktrace Coverage of Laplas Clipper and its Delivery Methods
In October and November 2022, Darktrace observed a significant increase in suspicious activity associated with Laplas Clipper across several customer networks. The activity consisted largely of:
User devices connecting to a suspicious endpoint.
User devices making HTTP GET requests to an endpoint associated with the SmokeLoader loader malware, which was installed on the user’s device.
User devices making HTTP connections to the Laplas Clipper download server “clipper[.]guru”, from which it downloads spoofed wallet addresses to divert crypto-currency payments.
In one particular instance, a compromised device was observed connecting to endpoints associated with SmokeLoader shortly before connecting to a Laplas Clipper download server. In other instances, devices were detected connecting to other anomalous endpoints including the domains shonalanital[.]com, transfer[.]sh, and pc-world[.]uk, which appears to be mimicking the legitimate endpoint thepcworld[.]com.
Additionally, some compromised devices were observed attempting to connect malicious IP addresses including 193.169.255[.]78 and 185.215.113[.]23, which are associated with the RedLine stealer malware. Additionally, Darktrace observed connections to the IP addresses 195.178.120[.]154 and 195.178.120[.]154, which are associated with SmokeLoader, and 5.61.62[.]241, which open-source intelligence has associated with Cobalt Strike.

Figure 2: The event log of an infected device attempting to connect to IP addresses associated with the RedLine stealer malware, and the actions RESPOND took to block these attempts.
The following DETECT/Network models breached in response to these connections:
Compromise / Beacon to Young Endpoint
Compromise / Slow Beaconing Activity to External Rare
Compromise / Beacon for 4 Days
Compromise / Beaconing Activity to External Rare
Compromise / Sustained TCP Beaconing Activity to Rare Endpoint
Anomalous Connection / Multiple Failed Connections to Rare Endpoints
Compromise / Large Number of Suspicious Failed Connections
Compromise / HTTP Beaconing to Rare Destination
Compromise / Post and Beacon to Rare External
Anomalous Connection / Callback on Web Facing Device
DETECT/Network is able to identify such activity as its models operate based on a device’s usual pattern of behavior, rather than a static list of indicators of compromise (IOCs). As such, Darktrace can quickly identify compromised devices that deviate for their expected pattern of behavior by connecting to newly created malicious endpoints or C2 infrastructure, thereby triggering an alert.
In one example, RESPOND/Network autonomously intercepted a compromised device attempting to connect to the Laplas Clipper C2 server, preventing it from downloading SmokeLoader and subsequently, Laplas Clipper itself.
Figure 3: The event log of an infected device attempting to connect to the Laplas Clipper download server, and the actions RESPOND/Network took to block these attempts.
In another example, DETECT/Network observed an infected device attempting to perform numerous DNS Requests to a crypto-currency mining pool associated with the Monero digital currency.
This activity caused the following DETECT/Network models to breach:
Compromise / Monero Mining
Compromise / High Priority Crypto Currency Mining
RESPOND/Network quickly intervened, enforcing a previously established pattern of life on the device, ensuring it could not perform any unexpected activity, and blocking the connections to the endpoint in question for an hour. These actions carried out by Darktrace’s autonomous response technology prevented the infected device from carrying out crypto-mining activity, and ensured the threat actor could not perform any additional malicious activity.
Figure 4. The event log of an infected devices showing DNS requests to the Monero crypto-mining pool, and the actions taken to block them by RESPOND/Network.
Finally, in instances when RESPOND/Network was not activated, external connections to the Laplas Clipper C2 server were nevertheless monitored by DETECT/Network, and the customer’s security team were notified of the incident.
Conclusion
The rise of information stealing malware variants such as Laplas Clipper highlights the importance of crypto-currency and crypto-mining in the malware ecosystem and more broadly as a significant cyber security concern. Crypto-mining is often discounted as background noise for security teams or compliance issues that can be left untriaged; however, malware strains like Laplas Clipper demonstrate the real security risks posed to digital estates from threat actors focused on crypto-currency.
Leveraging its Self-Learning AI, DETECT/Network and RESPOND/Network are able to work in tandem to quickly identify connections to suspicious endpoints and block them before any malicious software can be downloaded, safeguarding customers.

Crypto Wallets Continue to be Drained in Elaborate Social Media Scam
Overview
Continued research by Darktrace has revealed that cryptocurrency users are being targeted by threat actors in an elaborate social engineering scheme that continues to evolve. In December 2024, Cado Security Labs detailed a campaign targeting Web 3 employees in the Meeten campaign. The campaign included threat actors setting up meeting software companies to trick users into joining meetings and installing the information stealer Realst disguised as video meeting software.
The latest research from Darktrace shows that this campaign is still ongoing and continues to trick targets to download software to drain crypto wallets. The campaign features:
Threat actors creating fake startup companies with AI, gaming, video meeting software, web3 and social media themes.
Use of compromised X (formerly Twitter) accounts for the companies and employees - typically with verification to contact victims and create a facade of a legitimate company.
Notion, Medium, Github used to provide whitepapers, project roadmaps and employee details.
Windows and macOS versions.
Stolen software signing certificates in Windows versions for credibility and defense evasion.
Anti-analysis techniques including obfuscation, and anti-sandboxing.
To trick as many victims as possible, threat actors try to make the companies look as legitimate as possible. To achieve this, they make use of sites that are used frequently with software companies such as Twitter, Medium, Github and Notion. Each company has a professional looking website that includes employees, product blogs, whitepapers and roadmaps. X is heavily used to contact victims, and to increase the appearance of legitimacy. Some of the observed X accounts appear to be compromised accounts that typically are verified and have a higher number of followers and following, adding to the appearance of a real company.
Figure 1: Example of a compromised X account to create a “BuzzuAI” employee.
The threat actors are active on these accounts while the campaign is active, posting about developments in the software, and product marketing. One of the fake companies part of this campaign, “Eternal Decay”, a blockchain-powered game, has created fake pictures pretending to be presenting at conferences to post on social media, while the actual game doesn’t exist.
Figure 2: From the Eternal Decay X account, threat actors have altered a photo from an Italian exhibition (original on the right) to make it look like Eternal Decay was presented.
In addition to X, Medium is used to post blogs about the software. Notion has been used in various campaigns with product roadmap details, as well as employee lists.
Figure 3: Notion project team page for Swox.
Github has been used to detail technical aspects of the software, along with Git repositories containing stolen open-source projects with the name changed in order to make the code look unique. In the Eternal Decay example, Gitbook is used to detail company and software information. The threat actors even include company registration information from Companies House, however they have linked to a company with a similar name and are not a real registered company.
Figure 4: From the Eternal Decay Gitbook linking to a company with a similar name on Companies House.
Figure 5: Gitbook for “Eternal Decay” listing investors.
Figure 6: Gameplay images are stolen from a different game “Zombie Within” and posted pretending to be Eternal Decay gameplay.
In some of the fake companies, fake merchandise stores have even been set up. With all these elements combined, the threat actors manage to create the appearance of a legitimate start-up company, increasing their chances of infection.
Each campaign typically starts with a victim being contacted through X messages, Telegram or Discord. A fake employee of the company will contact a victim asking to test out their software in exchange for a cryptocurrency payment. The victim will be directed to the company website download page, where they need to enter a registration code, provided by the employee to download a binary. Depending on their operating system, the victim will be instructed to download a macOS DMG (if available) or a Windows Electron application.
Figure 7: Example of threat actor messaging a victim on X with a registration code.
Windows Version
Similar to the aforementioned Meeten campaign, the Windows version being distributed by the fake software companies is an Electron application. Electron is an open-source framework used to run Javascript apps as a desktop application. Once the user follows directions sent to them via message, opening the application will bring up a Cloudflare verification screen.
Figure 8: Cloudflare verification screen.
The malware begins by profiling the system, gathering information like the username, CPU and core count, RAM, operating system, MAC address, graphics card, and UUID.
Figure 9: Code from the Electron app showing console output of system profiling.
A verification process occurs with a captcha token extracted from the app-launcher URL and sent along with the system info and UUID. If the verification is successful, an executable or MSI file is downloaded and executed quietly. Python is also retrieved and stored in /AppData/Temp, with Python commands being sent from the command-and-control (C2) infrastructure.
Figure 10: Code from the Electron app looping through Python objects.
As there was no valid token, this process did not succeed. However, based on previous campaigns and reports from victims on social media, an information stealer targeting crypto wallets is executed at this stage. A common tactic in the observed campaigns is the use of stolen code signing certificates to evade detection and increase the appearance of legitimate software. The certificates of two legitimate companies Jiangyin Fengyuan Electronics Co., Ltd. and Paperbucketmdb ApS (revoked as of June 2025) were used during this campaign.
MacOS Version
For companies that have a macOS version of the malware, the user is directed to download a DMG. The DMG contains a bash script and a multiarch macOS binary. The bash script is obfuscated with junk, base64 and is XOR’d.
Figure 11: Obfuscated Bash script.
After decoding, the contents of the script are revealed showing that AppleScript is being used. The script looks for disk drives, specifically for the mounted DMG “SwoxApp” and moves the hidden .SwoxApp binary to /tmp/ and makes it executable. This type of AppleScript is commonly used in macOS malware, such as Atomic Stealer.
Figure 12: AppleScript used to mount the malware and make it executable.
The SwoxApp binary is the prominent macOS information stealer Atomic Stealer. Once executed the malware performs anti-analysis checks for QEMU, VMWare and Docker-OSX, the script exits if these return true. The main functionality of Atomic Stealer is to steal data from stores including browser data, crypto wallets, cookies and documents. This data is compressed into /tmp/out.zip and sent via POST request to 45[.]94[.]47[.]167/contact. An additional bash script is retrieved from 77[.]73[.]129[.]18:80/install.sh.
Figure 13: Additional Bash script ”install.sh”.
Install.sh, as shown in Figure 13, retrieves another script install_dynamic.sh from the server https://mrajhhosdoahjsd[.]com. Install_dynamic.sh downloads and extracts InstallerHelper.app, then sets up persistence via Launch Agent to run at login.
Figure 14: Persistence added via Plist configuration.
This plist configuration installs a macOS LaunchAgent that silently runs the app at user login. RunAtLoad and KeepAlive keys are used to ensure the app starts automatically and remains persistent.
The retrieved binary InstallerHelper is an Objective-C/Swift binary that logs active application usage, window information, and user interaction timestamps. This data is written to local log files and periodically transmits the contents to https://mrajhhoshoahjsd[.]com/collect-metrics using scheduled network requests.

A “traffer” malware group is an organized cybercriminal operation that specializes in directing internet users to malicious content typically information-stealing malware through compromised or deceptive websites, ads, and links. They tend to operate in teams with hierarchical structures with administrators recruiting “traffers” (or affiliates) to generate traffic and malware installs via search engine optimization (SEO), YouTube ads, fake software downloads, or owned sites, then monetize the stolen credentials and data via dedicated marketplaces.
A prominent traffer group “CrazyEvil” was identified by Recorded Future in early 2025. The group, who have been active since at least 2021, specialize in social engineering attacks targeted towards cryptocurrency users, influencers, DeFi professionals, and gaming communities. As reported by Recorded Future, CrazyEvil are estimated to have made millions of dollars in revenue from their malicious activity. CrazyEvil and their sub teams create fake software companies, similar to the ones described in this blog, making use of Twitter and Medium to target victims. As seen in this campaign, CrazyEvil instructs users to download their software which is an info stealer targeting both macOS and Windows users.
While it is unclear if the campaigns described in this blog can be attributed to CrazyEvil or any sub teams, the techniques described are similar in nature. This campaign highlights the efforts that threat actors will go to make these fake companies look legitimate in order to steal cryptocurrency from victims, in addition to use of newer evasive versions of malware.

Defending the Cloud: Stopping Cyber Threats in Azure and AWS with Darktrace
Real-world intrusions across Azure and AWS
As organizations pursue greater scalability and flexibility, cloud platforms like Microsoft Azure and Amazon Web Services (AWS) have become essential for enabling remote operations and digitalizing corporate environments. However, this shift introduces a new set of security risks, including expanding attack surfaces, misconfigurations, and compromised credentials frequently exploited by threat actors.
This blog dives into three instances of compromise within a Darktrace customer’s Azure and AWS environment which Darktrace.
The first incident took place in early 2024 and involved an attacker compromising a legitimate user account to gain unauthorized access to a customer’s Azure environment.
The other two incidents, taking place in February and March 2025, targeted AWS environments. In these cases, threat actors exfiltrated corporate data, and in one instance, was able to detonate ransomware in a customer’s environment.
Case 1 - Microsoft Azure
Figure 1: Simplified timeline of the attack on a customer’s Azure environment.
In early 2024, Darktrace identified a cloud compromise on the Azure cloud environment of a customer in the Europe, the Middle East and Africa (EMEA) region.
Initial access
In this case, a threat actor gained access to the customer’s cloud environment after stealing access tokens and creating a rogue virtual machine (VM). The malicious actor was found to have stolen access tokens belonging to a third-party external consultant’s account after downloading cracked software.
With these stolen tokens, the attacker was able to authenticate to the customer’s Azure environment and successfully modified a security rule to allow inbound SSH traffic from a specific IP range (i.e., securityRules/AllowCidrBlockSSHInbound). This was likely performed to ensure persistent access to internal cloud resources.
Detection and investigation of the threat
Darktrace / IDENTITY recognized that this activity was highly unusual, triggering the “Repeated Unusual SaaS Resource Creation” alert.
Cyber AI Analyst launched an autonomous investigation into additional suspicious cloud activities occurring around the same time from the same unusual location, correlating the individual events into a broader account hijack incident.
Figure 2: Cyber AI Analyst’s investigation into unusual cloud activity performed by the compromised account.
Figure 3: Surrounding resource creation events highlighted by Cyber AI Analyst.
Figure 4: Surrounding resource creation events highlighted by Cyber AI Analyst.
“Create resource service limit” events typically indicate the creation or modification of service limits (i.e., quotas) for a specific Azure resource type within a region. Meanwhile, “Registers the Capacity Resource Provider” events refer to the registration of the Microsoft Capacity resource provider within an Azure subscription, responsible for managing capacity-related resources, particularly those related to reservations and service limits. These events suggest that the threat actor was looking to create new cloud resources within the environment.
Around ten minutes later, Darktrace detected the threat actor creating or modifying an Azure disk associated with a virtual machine (VM), suggesting an attempt to create a rogue VM within the environment.
Threat actors can leverage such rogue VMs to hijack computing resources (e.g., by running cryptomining malware), maintain persistent access, move laterally within the cloud environment, communicate with command-and-control (C2) infrastructure, and stealthily deliver and deploy malware.
Persistence
Several weeks later, the compromised account was observed sending an invitation to collaborate to an external free mail (Google Mail) address.
Darktrace deemed this activity as highly anomalous, triggering a compliance alert for the customer to review and investigate further.
The next day, the threat actor further registered new multi-factor authentication (MFA) information. These actions were likely intended to maintain access to the compromised user account. The customer later confirmed this activity by reviewing the corresponding event logs within Darktrace.
Case 2 – Amazon Web Services
Figure 5: Simplified timeline of the attack on a customer’s AWS environment
In February 2025, another cloud-based compromised was observed on a UK-based customer subscribed to Darktrace’s Managed Detection and Response (MDR) service.
How the attacker gained access
The threat actor was observed leveraging likely previously compromised credential to access several AWS instances within customer’s Private Cloud environment and collecting and exfiltrating data, likely with the intention of deploying ransomware and holding the data for ransom.
Darktrace alerting to malicious activity
This observed activity triggered a number of alerts in Darktrace, including several high-priority Enhanced Monitoring alerts, which were promptly investigated by Darktrace’s Security Operations Centre (SOC) and raised to the customer’s security team.
The earliest signs of attack observed by Darktrace involved the use of two likely compromised credentials to connect to the customer’s Virtual Private Network (VPN) environment.
Internal reconnaissance
Once inside, the threat actor performed internal reconnaissance activities and staged the Rclone tool “ProgramData\rclone-v1.69.0-windows-amd64.zip”, a command-line program to sync files and directories to and from different cloud storage providers, to an AWS instance whose hostname is associated with a public key infrastructure (PKI) service.
The threat actor was further observed accessing and downloading multiple files hosted on an AWS file server instance, notably finance and investment-related files. This likely represented data gathering prior to exfiltration.
Shortly after, the PKI-related EC2 instance started making SSH connections with the Rclone SSH client “SSH-2.0-rclone/v1.69.0” to a RockHoster Virtual Private Server (VPS) endpoint (193.242.184[.]178), suggesting the threat actor was exfiltrating the gathered data using the Rclone utility they had previously installed. The PKI instance continued to make repeated SSH connections attempts to transfer data to this external destination.
Darktrace’s Autonomous Response
In response to this activity, Darktrace’s Autonomous Response capability intervened, blocking unusual external connectivity to the C2 server via SSH, effectively stopping the exfiltration of data.
This activity was further investigated by Darktrace’s SOC analysts as part of the MDR service. The team elected to extend the autonomously applied actions to ensure the compromise remained contained until the customer could fully remediate the incident.
Continued reconissance
Around the same time, the threat actor continued to conduct network scans using the Nmap tool, operating from both a separate AWS domain controller instance and a newly joined device on the network. These actions were accompanied by further internal data gathering activities, with around 5 GB of data downloaded from an AWS file server.
The two devices involved in reconnaissance activities were investigated and actioned by Darktrace SOC analysts after additional Enhanced Monitoring alerts had triggered.
Lateral movement attempts via RDP connections
Unusual internal RDP connections to a likely AWS printer instance indicated that the threat actor was looking to strengthen their foothold within the environment and/or attempting to pivot to other devices, likely in response to being hindered by Autonomous Response actions.
This triggered multiple scanning, internal data transfer and unusual RDP alerts in Darktrace, as well as additional Autonomous Response actions to block the suspicious activity.
Suspicious outbound SSH communication to known threat infrastructure
Darktrace subsequently observed the AWS printer instance initiating SSH communication with a rare external endpoint associated with the web hosting and VPS provider Host Department (67.217.57[.]252), suggesting that the threat actor was attempting to exfiltrate data to an alternative endpoint after connections to the original destination had been blocked.
Further investigation using open-source intelligence (OSINT) revealed that this IP address had previously been observed in connection with SSH-based data exfiltration activity during an Akira ransomware intrusion [1].
Once again, connections to this IP were blocked by Darktrace’s Autonomous Response and subsequently these blocks were extended by Darktrace’s SOC team.
The above behavior generated multiple Enhanced Monitoring alerts that were investigated by Darktrace SOC analysts as part of the Managed Threat Detection service.
Figure 5: Enhanced Monitoring alerts investigated by SOC analysts as part of the Managed Detection and Response service.
Final containment and collaborative response
Upon investigating the unusual scanning activity, outbound SSH connections, and internal data transfers, Darktrace analysts extended the Autonomous Response actions previously triggered on the compromised devices.
As the threat actor was leveraging these systems for data exfiltration, all outgoing traffic from the affected devices was blocked for an additional 24 hours to provide the customer’s security team with time to investigate and remediate the compromise.
Additional investigative support was provided by Darktrace analysts through the Security Operations Service, after the customer's opened of a ticket related to the unfolding incident.
Figure 8: Simplified timeline of the attack
Around the same time of the compromise in Case 2, Darktrace observed a similar incident on the cloud environment of a different customer.
Initial access
On this occasion, the threat actor appeared to have gained entry into the AWS-based Virtual Private Cloud (VPC) networkvia a SonicWall SMA 500v EC2 instance allowing inbound traffic on any port.
The instance received HTTPS connections from three rare Vultr VPS endpoints (i.e., 45.32.205[.]52, 207.246.74[.]166, 45.32.90[.]176).
Lateral movement and exfiltration
Around the same time, the EC2 instance started scanning the environment and attempted to pivot to other internal systems via RDP, notably a DC EC2 instance, which also started scanning the network, and another EC2 instance.
The latter then proceeded to transfer more than 230 GB of data to the rare external GTHost VPS endpoint 23.150.248[.]189, while downloading hundreds of GBs of data over SMB from another EC2 instance.
Figure 7: Cyber AI Analyst incident generated following the unusual scanning and RDP connections from the initial compromised device.
The same behavior was replicated across multiple EC2 instances, whereby compromised instances uploaded data over internal RDP connections to other instances, which then started transferring data to the same GTHost VPS endpoint over port 5000, which is typically used for Universal Plug and Play (UPnP).
What Darktrace detected
Darktrace observed the threat actor uploading a total of 718 GB to the external endpoint, after which they detonated ransomware within the compromised VPC networks.
This activity generated nine Enhanced Monitoring alerts in Darktrace, focusing on the scanning and external data activity, with the earliest of those alerts triggering around one hour after the initial intrusion.
Darktrace’s Autonomous Response capability was not configured to act on these devices. Therefore, the malicious activity was not autonomously blocked and escalated to the point of ransomware detonation.
Conclusion
This blog examined three real-world compromises in customer cloud environments each illustrating different stages in the attack lifecycle.
The first case showcased a notable progression from a SaaS compromise to a full cloud intrusion, emphasizing the critical role of anomaly detection when legitimate credentials are abused.
The latter two incidents demonstrated that while early detection is vital, the ability to autonomously block malicious activity at machine speed is often the most effective way to contain threats before they escalate.
Together, these incidents underscore the need for continuous visibility, behavioral analysis, and machine-speed intervention across hybrid environments. Darktrace's AI-driven detection and Autonomous Response capabilities, combined with expert oversight from its Security Operations Center, give defenders the speed and clarity they need to contain threats and reduce operational disruption, before the situation spirals.
