Today's Global Event. Tomorrow's Brand: The DNS Security Risks Behind Brand Impersonation

 

Executive Summary

Every major global event creates opportunities for cybercriminals to exploit trust. Whether it's an international sporting tournament, a holiday shopping season, tax season, a product launch, or a breaking news event, attackers quickly register lookalike domains, create convincing phishing websites, and impersonate trusted organizations to steal credentials, payment information, and sensitive data.

While the themes of these campaigns change, the underlying attack infrastructure rarely does. Brand impersonation often begins in the Domain Name System (DNS)—a foundational internet service that remains one of the least monitored components of many organizations' external attack surface.

This article explores how attackers use DNS to enable brand impersonation, why these attacks continue to succeed, and how organizations can improve visibility into external DNS risks before they become customer-facing incidents.

 

Trust Has Become an Attack Surface

Cybercriminals have learned that exploiting trust is often easier than exploiting technology.

Rather than attempting to breach heavily defended networks, attackers increasingly focus on impersonating organizations that users already recognize and trust. By registering domains that closely resemble legitimate brands, threat actors can create convincing websites, phishing campaigns, fake customer portals, and fraudulent payment pages that appear authentic.

Major global events frequently amplify this activity because they generate urgency, increased web traffic, and heightened public interest. However, these campaigns are not limited to international sporting events. Retailers experience similar attacks during holiday shopping seasons. Financial institutions become targets during tax season. Airlines, healthcare providers, SaaS vendors, educational institutions, and government agencies are all routinely impersonated throughout the year.

The headlines change, but the attack pattern remains remarkably consistent.

 

Why DNS Plays a Central Role

Every fraudulent website begins with a domain.

Before attackers can launch phishing emails, distribute malware, or impersonate a trusted organization, they need internet infrastructure capable of appearing legitimate. DNS provides that foundation.

Common techniques include:

• Registering lookalike or typosquatted domains
• Exploiting visually similar internationalized domain names
• Creating fraudulent subdomains
• Leveraging compromised or abandoned DNS records
• Hijacking unused cloud resources through dangling DNS records

These domains often remain active long enough to deceive users before being identified and removed.

For security teams, this creates an important challenge: many of these risks exist entirely outside their corporate environment. Traditional endpoint, identity, and network security controls may never observe the infrastructure attackers create to impersonate the organization.

 

AI Is Making Brand Impersonation More Convincing

Generative AI has significantly lowered the barrier for creating highly convincing impersonation campaigns.

Attackers can now generate professional-quality websites, realistic customer support content, persuasive phishing emails, multilingual landing pages, and convincing marketing copy within minutes. AI allows these campaigns to scale rapidly while requiring little technical expertise.

When AI-generated content is combined with lookalike domains and DNS abuse, fraudulent websites become increasingly difficult for users to distinguish from legitimate ones.

Although AI receives much of the attention in today's security discussions, the infrastructure enabling many of these attacks often begins with something far older: DNS.

 

The Hidden Risks Organizations Often Miss

Most organizations actively monitor internal assets, cloud workloads, endpoints, identities, and applications. Far fewer continuously monitor their external DNS footprint.

This creates blind spots that attackers frequently exploit.

Examples include:

• Forgotten or abandoned domains that remain publicly accessible
• Dormant subdomains pointing to decommissioned cloud services
• Dangling CNAME records vulnerable to subdomain takeover
• Expired domains that can be re-registered by attackers
• Inconsistent DNS governance following mergers, acquisitions, or cloud migrations
• Unauthorized domain registrations designed to impersonate corporate brands

These issues are rarely caused by sophisticated malware or zero-day vulnerabilities. More often, they result from operational drift, incomplete asset inventories, or changes that were never fully documented.

Without continuous visibility, organizations may not discover these exposures until customers report fraudulent websites or security teams begin responding to phishing campaigns already in progress.

 

Brand Protection Is Now a Security Responsibility

Brand impersonation is often viewed as a marketing or legal issue.

In reality, it has become a cybersecurity challenge.

Every fraudulent domain can damage customer trust, expose sensitive information, increase help desk volume, and create regulatory or legal consequences. Security teams are increasingly expected to identify external infrastructure risks before they become public incidents.

This requires collaboration across security operations, IT, networking, risk management, legal, and brand protection teams.

Organizations that understand their complete internet-facing footprint are better positioned to detect suspicious domains, identify infrastructure weaknesses, and respond before attackers successfully exploit them.

 

Improving DNS Security Posture

Reducing DNS-related brand risk begins with improving visibility.

Security teams should establish processes that continuously:

• Inventory all public domains, subdomains, and DNS records
• Monitor for typosquatting, lookalike domains, and unauthorized registrations
• Identify dangling DNS records and orphaned cloud resources
• Validate DNS configurations after infrastructure changes
• Review domain ownership and expiration schedules
• Integrate DNS monitoring into broader external attack surface management programs

These practices help organizations identify risks earlier, reduce opportunities for impersonation, and strengthen overall cyber resilience.

 

Looking Beyond the Headlines

Brand impersonation campaigns will continue to evolve alongside major news events, seasonal shopping periods, mergers, product launches, and geopolitical developments.

The specific lure changes.

The infrastructure does not.

As organizations expand their digital footprint, DNS Posture Management (DNSPM) is becoming an increasingly important component of a modern cybersecurity strategy. By providing continuous visibility into DNS assets, configurations, and external exposure, DNSPM helps security teams identify misconfigurations, detect unauthorized or abandoned DNS records, uncover lookalike domains, and reduce opportunities for attackers to exploit trusted brands. Rather than treating DNS as simply operational infrastructure, organizations should view it as a critical layer of their external attack surface—one that requires continuous monitoring, governance, and risk management to protect customer trust and strengthen overall cyber resilience.
