Domain Spoofing – The registration or use of a domain name that closely r… #
Related terms: Typosquatting, homograph attack, IDN spoofing. Explanation: Attackers exploit minor misspellings or Unicode characters to deceive users. Practical application: Secure variations of the brand domain and employ DNS‑based authentication (e.G., DMARC) to reject emails from unauthorized domains. Challenges: The sheer number of possible variations makes comprehensive registration costly.
DMARC (Domain #
based Message Authentication, Reporting & Conformance) – An email authentication protocol that allows brand owners to specify how unauthenticated messages should be handled. Related terms: SPF, DKIM, email spoofing. Explanation: DMARC policies can instruct receiving servers to quarantine or reject emails that fail SPF or DKIM checks, reducing phishing success. Practical application: Publish a strict DMARC policy (“p=reject”) for the brand’s marketing domain and monitor aggregate reports for anomalies. Challenges: Misconfigured SPF/DKIM records can cause legitimate newsletters to be blocked, requiring careful testing.
Domain #
based Message Authentication (DKIM) – A cryptographic method that signs outgoing email with a private key, enabling recipients to verify its integrity. Related terms: DMARC, SPF, email signing. Explanation: DKIM adds a header containing a digital signature that aligns with the sender’s domain.

Homograph Attack – An attack that exploits visually similar characters fr… #
G., “А” Cyrillic vs “a” Latin). Related terms: IDN spoofing, Unicode phishing, domain spoofing. Explanation: Users may not notice the subtle character differences, leading them to malicious sites. Practical application: Educate brand teams to copy‑paste URLs into browsers and use browser extensions that reveal Unicode characters. Challenges: Detection tools must parse Unicode accurately, which can be resource‑intensive.
Identity‑Based Phishing (IBP) – Phishing attempts that leverage personal… #
Related terms: Spear‑phishing, social engineering, reconnaissance. Explanation: Attackers gather data from public profiles, then craft messages that appear to come from trusted colleagues or partners.

Spear‑Phishing – Targeted phishing attacks that use personalized informat… #
Related terms: IBP, whaling, credential harvesting. Explanation: Spear‑phishing often exploits relationships within a brand, such as pretending to be a senior executive requesting confidential data. Practical application: Implement verification workflows for any request involving sensitive brand assets, requiring a secondary confirmation channel. Challenges: High success rates due to the tailored nature of the messages.
Supply Chain Phishing – Phishing attempts that impersonate vendors, partn… #
Related terms: Business email compromise (BEC), third‑party risk, partner spoofing. Explanation: Attackers exploit trusted relationships to gain access to marketing platforms or financial systems.

URL Reputation Service – A database that scores web addresses based on hi… #
Related terms: Web filtering, safe browsing, blacklisting. Explanation: When a user clicks a link, the service checks the URL against known bad lists and can block access. Practical application: Configure brand workstations to query a reputable URL reputation service before opening any external link. Challenges: New phishing sites may not yet be listed, leading to a window of exposure.
Vanishing URL – A link that redirects to a different destination each tim… #
Related terms: Link shortener abuse, dynamic redirect, URL obfuscation. Explanation: Because the final landing page changes, static analysis tools may miss the malicious endpoint. Practical application: Deploy real‑time URL expansion tools that resolve the full redirect chain at the moment of click. Challenges: Increased latency and the need for continuous monitoring of the redirection service.
Whitelisting – The practice of allowing only pre‑approved senders, domain… #
Related terms: Allowlist, safe sender list, exception handling. Explanation: While useful for ensuring delivery of critical brand communications, improper whitelisting can create blind spots for phishing. Practical application: Maintain a dynamic whitelist that requires periodic review and is limited to verified brand partners. Challenges: Managing exceptions without opening avenues for attackers to masquerade as trusted entities.
Zero‑Day Phishing – Phishing attacks that exploit previously unknown vuln… #
Related terms: Zero‑day exploit, advanced persistent threat (APT), unknown IOC. Explanation: Because signatures are unavailable, traditional detection methods may miss these attacks. Practical application: Employ behavior‑based analytics and sandboxing to detect anomalous activity indicative of a zero‑day exploit. Challenges: High false‑positive potential and the need for rapid patching once the vulnerability is disclosed.
