Brand abuse refers to the unauthorized imitation of an organization's brand. Its discovery is often a reminder to organizations that they need to protect more than just their data and IP – their reputation is at stake. But brand impersonation can also be used to launch a direct attack against the organization – and those around it. 

During a first demonstration meeting recently, Darktrace PREVENT discovered a website deploying a classic trick: the letters ‘rn’ were used in sequence in an attempt to imitate the letter ‘m’ in the company’s name (e.g. “exarnple-brand.com”). Whilst obvious when you’re looking out for it, for an unsuspecting employee this goes easily unnoticed. 

This website was set up by an attacker two weeks before the PREVENT demo. The website was taken down immediately, and the company was also advised to launch an internal investigation to find out if somebody had received an email from this address. The company also launched an information campaign informing their supply chain of this attack, and this last activity resulted in the discovery that one of their suppliers had been scammed through the same email domain and had transferred a large sum of money towards a shell company that was not related to the main brand. By alerting that supplier, additional money transfers were prevented.

This example is part of a broader trend being seen across the industry. ZDNET’s Fraud Trends Report found that roughly 250,000 attacks in Q2 of 2021 involved some form of brand abuse. These attacks harm companies by inflicting reputational damage, incurring financial losses from fraudulent competition, or serving as steppingstones for larger threats like supply chain attacks.

Organizations work hard to cultivate brand identities that differentiate themselves from competitors and build relationships with consumers. Yet, the stronger and more recognizable a brand is, the more often it is targeted for abuse as malicious actors take advantage of their success to reach more victims. Companies with greater online presences or international operations across multiple channels are also at higher risk. 

Brand abuse takes many forms. It can be a website designed to look like it belongs to the brand to collect personal information such as email addresses and passwords. It can be an invoice sent by a vendor with a slight typo in its name. It can be an unauthorized branded webshop that never ships products to buyers. It can be a fake social media account directing customers to malicious websites that distribute malware or spreading fake news. It can be as simple as copyright or trademark infringement.

Figure 1: The general pattern malicious actors use for brand abuse.

Responding to Brand Abuse

Reconquering brand reputation after a brand abuse incident can prove to be much more difficult and costly than investing beforehand to help secure the brand. Risk detection and monitoring require a holistic approach to cover the diverse forms of brand abuse, and requires patrolling the internet for copycats, typo squatters, and other malicious appropriations. 

Figure 2: Mapping to the stages of brand abusein Figure 1, the security team has a set of signals to look for and actions totake to stop brand abuse before it is too late.

Protecting the brand identity and external attack surface can seem like a daunting task for security teams, especially in an age where monitoring internal systems proves enough of a challenge itself. Moreover, how often should the team perform this brand abuse monitoring? Companies can try to search every six months, every quarter, even every month, however there would still be gaps between when a threat actor launches an attack and when the security team discovers it. This is when AI becomes a tremendous ally, as it works at a speed and scale that human teams cannot. 

The Power of PREVENT

PREVENT/Attack Surface ManagementTM works autonomously and continuously to uncover instances of brand abuse, and proactively hardens defenses against any attack that might be launched as a result. 

It uses AI to distinguish a company’s external assets from the rest of the global internet. Its processing features learn brand-related assets such as logos and domain names. It also leverages natural language processing and image classification algorithms to tackle even the most ambiguous and error-prone assets encountered to identify and stop copycats and typosquatters. 

PREVENT/ASM carries out this comprehensive level of monitoring continuously, closing the gap between when an attacker spins up malicious infrastructure and when the security team identifies it. With PREVENT, should an attacker create a malicious website tomorrow morning, the security team will be alerted tomorrow morning. 

In addition to identifying brand abuse, PREVENT/ASM helps the team to collect all the relevant data needed to support a Notice and Takedown procedure. It also integrates with the rest of Darktrace’s security ecosystem to ensure that cyber defense is hardened ahead of time, should malicious assets discovered by PREVENT/ASM be used to launch an attack. 

For example, identifying a webpage impersonating a brand is useful data for email security. PREVENT forewarns Darktrace/Email of malicious domains, which in turn heightens its sensitivity against emails sent from this site. The same is true with regards to network traffic as well as endpoint security: an endpoint device visiting this host will have Darktrace DETECTTM + Darktrace RESPONDTM on higher alert – ready to immediately neutralize threatening activity when it occurs. 

This is the power of the Cyber AI Loop, a virtuous feedback cycle in which AI engines continuously feed into and strengthen one another.

And PREVENT not only identifies instances of brand abuse (along with Shadow IT, misconfigurations, supply chain risk, and other vulnerabilities), but it also prioritizes these risks according to exposure and potential damage and impact. With PREVENT/End-to-EndTM using Darktrace’s understanding of every device and connection inside an organization – every user and their interactions, every possible attack path – insights from the internal and external attack surface combine to give security teams a fully informed understanding of how they can spend their time most effectively to reduce cyber risk. 

In these ways, PREVENT not only monitors for brand abuse at a scope and scale far beyond the capabilities of human security teams, but it also integrates with DETECT + RESPOND to harden a company’s cyber security.

Email-Borne Cyber Risk: A Core Challenge for the CISO in the Age of Volume and Sophistication

Default blog imageDefault blog image

The challenge for CISOs

Despite continuous advances in security technologies, humans continue to be exploited by attackers. Credential abuse and social actions like phishing are major factors, accounting for around 60% of all breaches. These attacks rely less on technical vulnerabilities and more on exploiting human behavior and organizational processes. 

From my perspective as a former CISO, protecting humans concentrates three of today’s most pressing challenges: the sheer volume of email-based threats, their increasing sophistication, and the limitations of traditional employee awareness programs in moving the needle on risk. 

My personal experience of security awareness training as a CISO

With over 20 years’ experience as an ICT and Cybersecurity leader across various international organizations, I’ve seen security awareness training (SAT) in many guises. And while the cyber landscape is evolving in every direction, the effectiveness of SAT is reaching a plateau.  

Most programs I’ve seen follow a familiar pattern. Training is delivered through a combination of eLearning modules and internal sessions designed to reinforce IT policies. Employees are typically required to complete a slide deck or video, followed by a multiple-choice quiz. Occasional phishing simulations are distributed throughout the year.

The content is often static and unpersonalized, based on known threats that may already be outdated. Every employee regardless of role or risk exposure receives the same training and the same simulated phishing templates, from front-desk staff to the CEO.

The problem with traditional SAT programs

The issue with the approach to SAT outlined above is that the distribution of power is imbalanced. Humans will always be fallible, particularly when faced with increasingly sophisticated attacks. Providing generic, low-context training risks creating false confidence rather than genuine resilience. Let’s look at some of the problems in detail.

Timing and delivery

Employees today operate under constant cognitive load, making lots of rapid decisions every day to reduce their email volumes. Yet if employees are completing training annually, or on an ad hoc basis, it becomes a standalone occurrence rather than a continuous habit.  

As a result, retention is low. Employees often forget the lessons within weeks, a phenomenon known as the ‘Ebbinghaus Forgetting Curve.’

The graph illustrates that when you first learn something, the information disappears at an exponential rate without retention. In fact, according to the curve, you forget 50% of all new information within a day, and 90% of all new information within a week.  

Simultaneously, most training is conducted within a separate interface. Because it takes place away from the actual moment of decision-making, the "teachable moment" is lost. There is a cognitive disconnect between the action (clicking a link in Outlook) and the education (watching a video in a browser). 

People

In the context of professional risk management, the risks faced by different users are different. Static learning such as everyone receiving the same ‘Password Reset’ email doesn’t help users prepare for the specific threats they are likely to face. It also contributes to user fatigue, driven by repetitive training. And if users receive tests at the same time, news spreads among colleagues, hurting the efficacy of the test.  

Staff turnover introduces further risk. In many organizations, new employees gain access to systems before receiving meaningful training, reducing onboarding to little more than policy acknowledgment.

Measuring success

In my experience, solutions are standalone, without any correlation to other tools in the security stack. In some cases, the programs are delivered by HR rather than the security team, creating a complete silo.  

As a result, SAT is often perceived as a compliance exercise rather than a capability building function. The result is that poor-quality training does little to reduce the likelihood of compromise, regardless of completion rates or quiz performance.

What a modern SAT solution should look like

For today’s CISO, email represents the convergence point of high-volume, high-impact, and human-centric threats. Despite significant security investments, it remains one of the most difficult channels to secure effectively. Given these constraints, CISOs must evolve their approach to SAT.

Success lies in a balanced strategy one that combines advanced technology, attack surface reduction, and pragmatic user enablement, without over-relying on human vigilance as the final line of defense.

This means moving beyond traditional SAT toward continuous, contextual awareness, realistic simulations, and tight integration with security outcomes.

Three requirements for a modern SAT solution

  • Invisible protection: The optimum security solution is one that assists users without impeding their experience. The objective is to enhance human capabilities, rather than simply delivering a lecture. 
  • Real-time feedback: Rather than a monthly quiz, the ideal system would provide a prompt or warning when a user is about to engage with something suspicious. 
  • Positive culture: Shifting the focus away from a "gotcha" culture, which is a contributing factor to a resentment, and instead empowers employees to serve as "sensors" for the company.

How a Compromised eScan Update Enabled Multi‑Stage Malware and Blockchain C2

multi-stage malwareDefault blog imageDefault blog image

The rise of supply chain attacks

In recent years, the abuse of trusted software has become increasingly common, with supply chain compromises emerging as one of the fastest growing vectors for cyber intrusions. As highlighted in Darktrace’s Annual Threat Report 2026, attackers and state-actors continue to find significant value in gaining access to networks through compromised trusted links, third-party tools, or legitimate software. In January 2026, a supply chain compromise affecting MicroWorld Technologies’ eScan antivirus product was reported, with malicious updates distributed to customers through the legitimate update infrastructure. This, in turn, resulted in a multi‑stage loader malware being deployed on compromised devices [1][2].

An overview of eScan exploitation

According to eScan’s official threat advisory, unauthorized access to a regional update server resulted in an “incorrect file placed in the update distribution path” [3]. Customers associated with the affected update servers who downloaded the update during a two-hour window on January 20 were impacted, with affected Windows devices subsequently have experiencing various errors related to update functions and notifications [3].

While eScan did not specify which regional update servers were affected by the malicious update, all impacted Darktrace customer environments were located in the Europe, Middle East, and Africa (EMEA) region.

External research reported that a malicious 32-bit executable file , “Reload.exe”, was first installed on affected devices, which then dropped the 64-bit downloader, “CONSCTLX.exe”. This downloader establishes persistence by creating scheduled tasks such as “CorelDefrag”, which are responsible for executing PowerShell scripts. Subsequently, it evades detection by tampering with the Windows HOSTS file and eScan registry to prevent future remote updates intended for remediation. Additional payloads are then downloaded from its command-and-control (C2) server [1].

Darktrace’s coverage of eScan exploitation

Initial Access and Blockchain as multi-distributed C2 Infrastructure

On January 20, the same day as the aforementioned two‑hour exploit window, Darktrace observed multiple devices across affected networks downloading .dlz package files from eScan update servers, followed by connections to an anomalous endpoint, vhs.delrosal[.]net, which belongs to the attackers’ C2 infrastructure.

The endpoint contained a self‑signed SSL certificate with the string “O=Internet Widgits Pty Ltd, ST=SomeState, C=AU”, a default placeholder commonly used in SSL/TLS certificates for testing and development environments, as well as in malicious C2 infrastructure [4].

Utilizing a multi‑distributed C2 infrastructure, the attackers also leveraged domains linked with the Solana open‑source blockchain for C2 purposes, namely “.sol”. These domains were human‑readable names that act as aliases for cryptocurrency wallet addresses. As browsers do not natively resolve .sol domains, the Solana Naming System (formerly known as Bonfida, an independent contributor within the Solana ecosystem) provides a proxy service, through endpoints such as sol-domain[.]org, to enable browser access.

Darktrace observed devices connecting to blackice.sol-domain[.]org, indicating that attackers were likely using this proxy to reach a .sol domain for C2 activity. Given this behavior, it is likely that the attackers leveraged .sol domains as a dead drop resolver, a C2 technique in which threat actors host information on a public and legitimate service, such as a blockchain. Additional proxy resolver endpoints, such as sns-resolver.bonfida.workers[.]dev, were also observed.

Solana transactions are transparent, allowing all activity to be viewed publicly. When Darktrace analysts examined the transactions associated with blackice[.]sol, they observed that the earliest records dated November 7, 2025, which coincides with the creation date of the known C2 endpoint vhs[.]delrosal[.]net as shown in WHOIS Lookup information [4][5].

Subsequent instructions found within the transactions contained strings such as “CNAME= vhs[.]delrosal[.]net”, indicating attempts to direct the device toward the malicious endpoint. A more recent transaction recorded on January 28 included strings such as “hxxps://96.9.125[.]243/i;code=302”, suggesting an effort to change C2 endpoints. Darktrace observed multiple alerts triggered for these endpoints across affected devices.

Similar blockchain‑related endpoints, such as “tumama.hns[.]to”, were also observed in C2 activities. The hns[.]to service allows web browsers to access websites registered on Handshake, a decentralized blockchain‑based framework designed to replace centralized authorities and domain registries for top‑level domains. This shift toward decentralized, blockchain‑based infrastructure likely reflects increased efforts by attackers to evade detection.

In outgoing connections to these malicious endpoints across affected networks, Darktrace / NETWORK recognized that the activity was 100% rare and anomalous for both the devices and the wider networks, likely indicative of malicious beaconing, regardless of the underlying trusted infrastructure. In addition to generating multiple model alerts to capture this malicious activity across affected networks, Darktrace’s Cyber AI Analyst was able to compile these separate events into broader incidents that summarized the entire attack chain, allowing customers’ security teams to investigate and remediate more efficiently. Moreover, in customer environments where Darktrace’s Autonomous Response capability was enabled, Darktrace took swift action to contain the attack by blocking beaconing connections to the malicious endpoints, even when those endpoints were associated with seemingly trustworthy services.

Conclusion

Attacks targeting trusted relationships continue to be a popular strategy among threat actors. Activities linked to trusted or widely deployed software are often unintentionally whitelisted by existing security solutions and gateways. Darktrace observed multiple devices becoming impacted within a very short period, likely because tools such as antivirus software are typically mass‑deployed across numerous endpoints. As a result, a single compromised delivery mechanism can greatly expand the attack surface.

Attackers are also becoming increasingly creative in developing resilient C2 infrastructure and exploiting legitimate services to evade detection. Defenders are therefore encouraged to closely monitor anomalous connections and file downloads. Darktrace’s ability to detect unusual activity amidst ever‑changing tactics and indicators of compromise (IoCs) helps organizations maintain a proactive and resilient defense posture against emerging threats.
