Why It Matters

Email crafting is a critical skill in the arsenal of a phishing attacker, enabling them to bypass technical defenses and exploit human psychology. When an operator uses email crafting effectively, they can engender trust by mimicking legitimate communications, often resulting in high engagement rates. The art of email crafting involves adopting the language, tone, and format expected by the email’s target audience, ensuring that the email appears genuine at first glance.

Operators encounter email crafting in every stage of a phishing campaign, from the initial setup where they choose the look and language of the email, to the execution phase where these elements are delivered to the target. Successful email crafting can make or break the campaign’s effectiveness, directly impacting the engagement level, which in blue team assessments helps to highlight shortcomings in user awareness training programs.

In Practice

Effective email crafting in phishing can manifest in numerous ways, including:

Impersonation of Trusted Entities: An attacker crafts an email that appears to be from a popular service provider such as PayPal. The email subject might read “Important: Your Account Access Has Been Limited”, with the sender spoofed to display “support@paypal.com”. The email body includes a sophisticated layout mimicking PayPal’s typical communications and prompts the recipient to verify their account through a malicious link.
Urgency and Fear Tactics: To exploit urgency, an email might carry the subject line “Action Required: Deactivation of Subscription”. The email could masquerade as being from a department related to subscription services within the victim’s company, such as “billing@corporate-subscription.com”. The crafted message might warn the recipient that their subscription will be canceled unless they immediately update their payment information via a linked form.
Credential Harvesting: An email might imitate an internal IT notification, using a subject like “Scheduled Maintenance: Password Update Required”. Sent from a convincingly spoofed corporate IT email, like “it-admin@yourcompany.com”, the message informs employees of a mandatory password change through an attached document, which instead leads to a credential harvesting page.

In all these scenarios, the craft of the email is designed specifically to mimic the authentic look and communication style of trusted entities or colleagues, increasing the likelihood of a successful attack.
