What Is an Impersonation Attack?

An impersonation attack is a type of cyberattack in which an attacker pretends to be a trusted individual, organization, or service in order to deceive a target. The goal is to manipulate trust and influence user behavior, such as sharing sensitive information, approving actions, transferring funds, or accessing malicious resources.

Impersonation attacks can target both organizations and individuals. Common targets include brands, customer support teams, executives, colleagues, vendors, and trusted personal contacts.

How Does an Impersonation Attack Work?

Impersonation attacks rely on deception rather than technical exploitation alone. A typical attack may involve:

• An attacker assumes the identity of a trusted person or entity

• Trust is established through familiar names, branding, language, or context

• The victim is prompted to take an action, such as clicking a link, entering information, approving a request, or making a payment

These attacks often unfold across multiple channels and may combine social engineering with technical techniques to appear legitimate.

Common Impersonation Techniques

Impersonation attacks are carried out using a variety of methods, including:

• Email spoofing or lookalike sender addresses

• Domain lookalikes and cloned websites

• Fake online stores or service portals

• Spoofed customer support interactions

• Compromised accounts used to impersonate real users

• Social media or messaging platform impersonation

Not all impersonation attacks require victims to share credentials. Some aim to trigger direct actions, such as fraudulent purchases, wire transfers, or approvals, while others seek data, access, or long-term trust exploitation.
