Protecting Digital Assets: Domain Hijacking, Phishing and Brand Impersonation

Digital assets of a brand do not consist solely of website and social media accounts. Domain name, DNS records, corporate email infrastructure, SSL/TLS certificates, subdomains, and digital profiles used on behalf of the brand are parts of the same trust chain.

Compromising one weak link may give an attacker more than system access: they can exploit the brand’s identity to target customers, employees or partners.

Domain hijacking, phishing, typosquatting and brand impersonation are therefore key risks where cybersecurity meets brand protection.

What is Domain Hijacking?

Domain hijacking refers to unauthorised possession of control of a domain name. The attacker can access the registrar account, change DNS records, or abuse the domain transfer process.

As a result, visitors may be directed to a site controlled by the attacker, e-mail traffic may be affected, or fraudulent communication may be conducted on behalf of the brand.

What happens if a domain is hijacked?

• The website can be redirected to another server.
• Corporate email service may be interrupted.
• A fake payment or login page may be displayed.
• Customers can receive phishing messages on behalf of the brand.
• Search engine visibility and brand reputation can be damaged.
• DNS-based third-party services may be affected.

The registrar account is the critical layer

Domain security starts with the registrar account. If compromised, it can expose DNS and transfer settings to an attacker.

For this account:

• unique and powerful password,
• multifactor authentication,
• current recovery contact details,
• domain transfer lock,
• limited administrator access

must be implemented.

DNS Account is a Separate Risk Area

Even with a secure registrar, compromise of a separate DNS-provider account can have similar effects.

Unauthorised changes to A, AAAA, MX, CNAME or TXT records can redirect web or email traffic to attacker infrastructure.

What Does DNSSEC Provide?

DNSSEC can help verify the integrity of DNS responses in supported infrastructures. However, it alone does not prevent the domain account from being intercepted.

DNSSEC complements registrar security, MFA and change monitoring; it does not replace them.

The Connection Between Phishing and Brand Appropriation

Phishing usually aims to convince users that a message comes from a trusted source. A strong brand name is therefore valuable to attackers.

Attacker:

• can register domain that looks like a brand,
• can copy logo and corporate identity,
• can open a fake customer service account,
• can create fake campaign or pay screen,
• It may attempt to send emails on behalf of the brand.

What is Typosquatting?

Typosquatting is the use of domain names that are very similar to the actual domain but contain small spelling differences.

Methods such as letter reduction, letter changing, adding hyphens, using different extensions, or using visually similar characters can be seen.

Not all of these domains are automatically malicious. However, in terms of brand, their monitoring provides early risk detection.

How can lookalike domains be monitored?

Not only the full domain name of the brand, but possible variations can also be traced:

• spelling errors,
• different extensions,
• brand + campaign combinations,
• brand + support / login / payment statements,
• homoglyphs or visually similar characters.

Not every domain identified should be classified as a breach; active use, content, DNS, email configuration, and similarity to the brand should be evaluated.

Why are SPF, DKIM and DMARC important?

Email authentication is an important layer of control to reduce fraudulent email attempts on behalf of the brand.

SPF

It helps to identify which servers are authorised to send emails on behalf of the domain.

DKIM

It helps verify email through cryptographic signature.

DMARC

It combines SPF and DKIM results with domain policy and can provide reporting mechanism.

Inventory legitimate email sources before applying the strictest DMARC policy.

Subdomains should not be forgotten

Older campaign pages, test environments, or SaaS links that are no longer in use can lead to risks such as subdomain takeover.

Records that are no longer used on DNS must be cleaned regularly.

SSL/TLS and Certificate Tracking

Creating certificates in new domains that look like brands can sometimes provide an early signal for possible misuse. Certificate Transparency records can be used as an auxiliary data source in such analysis.

Certificate issuance alone does not prove infringement; assess it alongside other findings.

What to Do When a Fake Site Is Detected?

The first reflex should not be just sending a message to the hosting company. The evidence package must be prepared first.

• full URL,
• domain and DNS information,
• screenshots,
• date and time records,
• trademark elements imitated,
• If there is a phishing form or payment page,
• hosting and registrar information,
• search engine or ad visibility

can be documented.

Takedowns involve more than one channel

Separate processes can be conducted with registrar, hosting provider, CDN, search engine, advertising network, social media platform or other service providers based on the nature of the event.

Application procedures for types of violations, such as trademark rights, phishing, malware and personality rights, may not be the same.

First Intervention in Domain Hijacking Incident

1. Contact the registrar

Account recovery and domain lock process must be started.

2. Detection of DNS changes

It should be compared which records have been changed.

3. Renewal of authorizations

Change passwords, MFA settings and any necessary API keys.

4. Check the effect on email

MX and authentication records must be examined.

5. Preserve logs

Preserve registrar, DNS, email and server logs for incident analysis.

Why Should Cybersecurity Work Together With Brand Protection?

Traditional cybersecurity can focus on protecting the institution's own systems. Digital brand protection also monitors fake domain, fake account, fake sales channel, and misleading digital assets created outside the institution's control.

Assessing both areas together provides a more accurate picture of the brand’s threat surface.

What Can Be Watched on a Digital Risk Map?

• similar domain records,
• fake social media accounts,
• phishing pages on behalf of the brand,
• unauthorised sales and fraudulent product advertisements,
• Fake mobile apps,
• advertising uses on behalf of the brand,
• domain and DNS changes,
• Reputation attacks.

The B10 Approach

The B10 Digital Agency addresses digital asset security without separating technical infrastructure and brand protection processes. It aims to identify the risks of brands, domains, fake accounts and digital channels, creating risk maps that operations teams can prioritize.

• Brand Protection & Monitoring
• Digital PR & Reputation Management
• Web Development & Secure Infrastructure

Conclusion

Domain hijacking and phishing attacks on behalf of the brand are not just technical security problems. Brand trust, customer safety, and commercial reputation can be affected by the same event. Therefore, domain security, email verification, external threat monitoring, and rapid takedown processes must be combined in a single digital risk management approach.
