Established trust can then be leveraged to accomplish an adversary’s ultimate goals, possibly against multiple victims. </p><p>In many cases of business email compromise or email fraud campaigns, adversaries use impersonation to defraud victims -- deceiving them into sending money or divulging information that ultimately enables <a href="/techniques/T1657">Financial Theft</a>.</p><p>Adversaries will often also use social engineering techniques such as manipulative and persuasive language in email subject lines and body text such as <code>payment</code>, <code>request</code>, or <code>urgent</code> to push the victim to act quickly before malicious activity is detected. These campaigns are often specifically targeted against people who, due to job roles and/or accesses, can carry out the adversary’s goal. </p><p>Impersonation is typically preceded by reconnaissance techniques such as <a href="/techniques/T1589">Gather Victim Identity Information</a> and <a href="/techniques/T1591">Gather Victim Org Information</a> as well as acquiring infrastructure such as email domains (i.e. <a href="/techniques/T1583/001">Domains</a>) to substantiate their false identity.<span onclick=scrollToRef('scite-1') id="scite-ref-1-a" class="scite-citeref-number" title="Bart Lenaerts-Bergmans.
