User Training involves educating employees and contractors on recognizing, reporting, and preventing cyber threats that rely on human interaction, such as phishing, social engineering, and other manipulative techniques. Comprehensive training programs create a human firewall by empowering users to be an active component of the organization's cybersecurity defenses. This mitigation can be implemented through the following measures: Create Comprehensive Training Programs: - Design training modules tailored to the organization's risk profile, covering topics such as phishing, password management, and incident reporting. - Provide role-specific training for high-risk employees, such as helpdesk staff or executives. Use Simulated Exercises: - Conduct phishing simulations to measure user susceptibility and provide targeted follow-up training. - Run social engineering drills to evaluate employ…
MITRE mitigation sourceImpersonation
Adversaries may impersonate a trusted person or organization in order to persuade and trick a target into performing some action on their behalf. For example, adversaries may communicate with victims (via [Phishing for Information](https://attack.mitre.org/techniques/T1598), [Phishing](https://attack.mitre.org/techniques/T1566), or [Internal Spearphishing](https://attack.mitre.org/techniques/T1534)) while impersonating a known sender such as an executive, colleague, or third-party vendor. Established trust can then be leveraged to accomplish an adversary’s ultimate goals, possibly against multiple victims. 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 [Financial Theft](https://attack.mitre.org/techniques/T1657). Adversaries will often also use social engineering techniques such as manipulative and persuasive language in email subject lines and body text such as `payment`, `request`, or `urgent` 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. Impersonation is typically preceded by reconnaissance techniques such as [Gather Victim Identity Information](https://attack.mitre.org/techniques/T1589) and [Gather Victim Org Information](https://attack.mitre.org/techniques/T1591) as well as acquiring infrastructure such as email domains (i.e. [Domains](https://attack.m…

MITRE mitigations
A Threat Intelligence Program enables organizations to proactively identify, analyze, and act on cyber threats by leveraging internal and external data sources. The program supports decision-making processes, prioritizes defenses, and improves incident response by delivering actionable intelligence tailored to the organization's risk profile and operational environment. This mitigation can be implemented through the following measures: Establish a Threat Intelligence Team: - Form a dedicated team or assign responsibility to existing security personnel to collect, analyze, and act on threat intelligence. Define Intelligence Requirements: - Identify the organization’s critical assets and focus intelligence gathering efforts on threats targeting these assets. Leverage Internal and External Data Sources: - Collect intelligence from internal sources such as logs, incidents, and alerts. Subsc…
MITRE mitigation sourceMITRE detection strategies and analytics
- AN0792 · Analytic 0792 — Monitor for anomalous email activity originating from Windows-hosted applications (e.g., Outlook) where the sending account name or display name does not match the underlying SMTP address. Detect abnormal volume of outbound messages containing sensitive keywords (e.g., 'payment', 'wire transfer') or anomalous login locations for accounts associated with email sending activity.
- AN0793 · Analytic 0793 — Monitor mail server logs (Postfix, Sendmail, Exim) for anomalous From headers mismatching authenticated SMTP identities. Detect abnormal relay attempts, spoofed envelope-from values, or large-scale outbound campaigns targeting internal users.
- AN0794 · Analytic 0794 — Monitor Mail.app activity or unified logs for anomalous SMTP usage, including mismatches between display name and authenticated AppleID or Exchange credentials. Detect use of third-party mail utilities that attempt to send on behalf of corporate identities.
- AN0795 · Analytic 0795 — Monitor SaaS mail platforms (Google Workspace, M365, Okta-integrated apps) for SendAs/SendOnBehalfOf operations where the delegated permissions are unusual or newly granted. Detect impersonation attempts where adversaries configure rules to auto-forward or auto-reply with impersonated content.
- AN0796 · Analytic 0796 — Monitor Office Suite applications (Outlook, Word mail merge, Excel macros) for abnormal automated message sending, especially when macros or scripts trigger email delivery. Detect patterns of impersonation language (urgent, payment, executive request) combined with anomalous execution of Office macros.
