How executive impersonation campaigns develop, and how they can be contained

Executive impersonation is the unauthorised use of a business leader’s name, image or identity to deceive employees, customers, partners or the public. It can involve fake social media profiles, lookalike domains, fraudulent advertisements, deceptive email accounts and AI-generated audio or video.

These attacks often begin before the first fraudulent message is sent. The attacker first creates the infrastructure needed to appear credible. This preparation period gives security teams an opportunity to detect and disrupt the campaign before it reaches an employee, customer or business partner.

Why early detection matters

An executive impersonation campaign usually starts with an external asset rather than a direct request. An attacker may create:

• A social media profile using the executive’s name, photograph and job title
• A domain designed to resemble the organisation’s legitimate domain
• A free email account that places the executive’s name in the display-name field
• A fraudulent advertisement, news page or investment site using the executive’s identity

These assets may be created and maintained before they are used. An established-looking profile with connections and activity can appear more credible than an account created immediately before contact.

This period between asset creation and activation is a critical detection window. Fake profiles and lookalike domains are externally visible, allowing organisations to identify and investigate them before the attacker begins approaching potential victims.

Once the conversation moves to a personal email account, messaging application or private phone number, the organisation may have far less visibility. Early external monitoring therefore reduces the attacker’s opportunity to establish trust.

How attackers use public information

Executives are highly visible by design. Company websites, annual reports, press releases and conference programmes reveal their names, roles, photographs and public activities. Professional networking sites may also expose reporting relationships, new appointments and the identities of employees who work in finance or executive support.

Attackers can use this information to identify people who are likely to respond to an instruction from a senior leader. Common targets include:

• Executive assistants
• Finance and accounts-payable employees
• Procurement teams
• Payroll personnel
• New employees who may not recognise an executive’s normal communication style

The request may involve an urgent payment, gift-card purchase, payroll change, disclosure of sensitive information or a move to a private messaging application. Requests to change supplier bank details are another common variation.

Attackers may time their approach to coincide with an executive’s travel, public appearance or board meeting. The executive’s supposed unavailability then becomes part of the story: the matter is urgent, confidential and cannot be confirmed through normal channels.

AI-generated voice or video can add credibility, but it does not change the attacker’s objective. The victim is still being pressured to transfer money, disclose information or bypass an established control.

Why DMARC is necessary but not sufficient

DMARC helps prevent unauthorised use of an organisation’s email domain. When correctly configured and enforced, it can reduce messages that falsely claim to originate from that protected domain.

However, DMARC does not determine whether the human-readable sender name is genuine. It also does not prevent attackers from using visually similar domains. These limitations are explicitly recognised in the current DMARC specification.

For example, an attacker can create an address on a free email service and set the display name to the CEO’s name. The message may pass authentication for the free email provider’s domain because it is not technically claiming to come from the organisation’s domain.

This is why email authentication should be combined with:

• Monitoring for lookalike domains and external impersonation
• Inbound impersonation controls for high-risk employees
• Clear warnings for messages originating outside the organisation
• Independent verification of financial and credential-related requests
• Regular review of executive identities exposed across public channels

Detecting the campaign during preparation

Security teams should monitor for the external assets attackers need to establish credibility. This includes executive names and images, suspicious social profiles, lookalike domains, fraudulent advertisements and websites that misuse leadership identities.

A copied executive photograph is a useful indicator because attackers may change an account’s name while continuing to use the same image. Image matching and reverse image search can help identify this reuse. However, a matching name or photograph is not proof of malicious intent on its own. Each finding should be validated against its context, behaviour and relationship to other indicators.

CTM360’s CyberBlindspot monitors external digital channels for threats involving organisations, brands and executives. Its VIP and Executive Protection capabilities help detect fake executive profiles, impersonation websites and related identity abuse. Findings are validated so that response teams can focus on credible threats rather than simple name matches.

Build verification around the request, not the channel

Monitoring finds fake profiles and lookalike domains early and supports a removal, and each is worth doing before any message goes out. Email controls play a narrower role than people expect: enforced DMARC blocks spoofing of the company's exact domain, but a message from a free account with the executive's name in the display field passes authentication because it never claims to be from the company's domain at all.

Payment and credential requests need a verification step that works whatever the sender appears to be. A payment instruction that arrives through a messaging app gets confirmed by calling a number held on file. The step has to cover executive assistants and new starters, since they are closest to the executive's name and are the most likely to be asked. Verification applies to changes of supplier bank details in the same way, because a request from a senior name to update an account number is the same fraud with a different story.

Why takedowns can stall

Detecting an impersonation account does not automatically result in its removal. Social platforms, registrars and hosting providers apply different policies and evidentiary requirements. A request may need screenshots, account details, proof of identity, evidence of malicious behaviour or confirmation that the reporter is authorised to act.

Internal handoffs can create additional delay. The security team may need approval from legal, brand, communications or the affected executive before it can complete a submission. If these responsibilities have not been agreed in advance, a fraudulent account can remain active while evidence and authorisation are assembled.

Organisations can reduce this friction by:

• Defining ownership for executive impersonation incidents
• Maintaining approved executive profiles and contact information
• Pre-authorising the appropriate team or provider to submit reports
• Preserving evidence as soon as an incident is detected
• Tracking each case through submission, escalation and final resolution

Removal times ultimately depend on the policies and response processes of the relevant platform or provider. Takedowns should therefore be measured by exposure time and case status, not simply by the number of reports submitted.

How CTM360 supports detection and disruption

CyberBlindspot brings together external threat detection, validation and response for impersonation risks affecting an organisation and its executives.

When CTM360 validates an incident, its Cyber Incident Response Team manages the response workflow through Managed Takedowns. This can include evidence collection, initial reporting, escalation and follow-up with the relevant platform, registrar, hosting provider or other service.

This managed process reduces the operational burden on internal teams while maintaining visibility into the incident and its status. Because removal remains subject to third-party policies and review, continued monitoring is also important. Attackers may recreate an account, change its name or move the campaign to another platform.

A layered approach to executive impersonation

No single control can contain every form of executive impersonation. Effective protection combines:

1. External monitoring for fake profiles, lookalike domains and identity misuse
2. Email authentication and inbound impersonation controls
3. Independent verification for sensitive requests
4. Clear ownership and pre-approved response procedures
5. Managed escalation and takedown workflows
6. Continued monitoring for recurrence

The objective is to detect the attacker’s infrastructure early, prevent fraudulent instructions from being trusted and reduce the time a malicious asset remains accessible.

FAQs

What is executive impersonation?

Executive impersonation is the unauthorised use of a senior leader’s name, image, title or identity to deceive employees, customers, investors or business partners. It may involve fake social media profiles, lookalike domains, fraudulent websites, deceptive emails, advertisements or AI-generated media.

How do executive impersonation attacks begin?

They often begin with the creation of an external asset, such as a fake profile, lookalike domain or email account. Attackers then use public information about the executive and the organisation to identify suitable targets and make their requests appear credible.

Why does DMARC not stop every executive impersonation email?

DMARC authenticates the domain used in an email’s sender address. It does not validate the human-readable display name and does not prevent the use of lookalike domains. An attacker can therefore use an external email account while displaying an executive’s name.

How should organisations verify urgent executive requests?

Requests involving money, credentials or changes to financial information should be confirmed through a separate, trusted channel. Employees should use contact information already held by the organisation, not a phone number or link supplied in the request.

Why can fake-profile takedowns take time?

Platforms and service providers have different review processes and evidence requirements. Delays may also occur when internal teams need to obtain authorisation, identity documentation or legal approval before submitting or escalating a request.

How does CTM360 address executive impersonation?

CyberBlindspot monitors external digital channels for fake executive profiles, impersonation websites, lookalike domains and related identity abuse. Validated incidents can be escalated through CTM360 Managed Takedowns, with the response workflow managed by its Cyber Incident Response Team.
