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 sourceEmail Bombing
Adversaries may flood targeted email addresses with an overwhelming volume of messages. This may bury legitimate emails in a flood of spam and disrupt business operations.(Citation: sophos-bombing)(Citation: krebs-email-bombing) An adversary may accomplish email bombing by leveraging an automated bot to register a targeted address for e-mail lists that do not validate new signups, such as online newsletters. The result can be a wave of thousands of e-mails that effectively overloads the victim’s inbox.(Citation: krebs-email-bombing)(Citation: hhs-email-bombing) By sending hundreds or thousands of e-mails in quick succession, adversaries may successfully divert attention away from and bury legitimate messages including security alerts, daily business processes like help desk tickets and client correspondence, or ongoing scams.(Citation: hhs-email-bombing) This behavior can also be used as a tool of harassment.(Citation: krebs-email-bombing) This behavior may be a precursor for [Spearphishing Voice](https://attack.mitre.org/techniques/T1566/004). For example, an adversary may email bomb a target and then follow up with a phone call to fraudulently offer assistance. This social engineering may lead to the use of [Remote Access Software](https://attack.mitre.org/techniques/T1663) to steal credentials, deploy ransomware, conduct [Financial Theft](https://attack.mitre.org/techniques/T1657)(Citation: sophos-bombing), or engage in other malicious activity.(Citation: rapid7-email-bombing)

MITRE mitigations
Software configuration refers to making security-focused adjustments to the settings of applications, middleware, databases, or other software to mitigate potential threats. These changes help reduce the attack surface, enforce best practices, and protect sensitive data. This mitigation can be implemented through the following measures: Conduct a Security Review of Application Settings: - Review the software documentation to identify recommended security configurations. - Compare default settings against organizational policies and compliance requirements. Implement Access Controls and Permissions: - Restrict access to sensitive features or data within the software. - Enforce least privilege principles for all roles and accounts interacting with the software. Enable Logging and Monitoring: - Configure detailed logging for key application events such as authentication failures, configura…
MITRE mitigation sourceMITRE detection strategies and analytics
- AN1008 · Analytic 1008 — Detect abnormally high volume of inbound email messages or repetitive attachments being delivered to a single mailbox within a short time window. Defenders should look for anomalous spikes in message counts and repetitive attachment file creation events correlated with targeted users.
- AN1009 · Analytic 1009 — Monitor mail server logs (e.g., Postfix, Sendmail) for excessive connections or inbound message counts targeting a single recipient. Correlate with repetitive attachment storage in /var/mail or /var/spool/mail directories.
- AN1010 · Analytic 1010 — Detect abnormal use of email clients (e.g., Outlook, Thunderbird) showing mass arrival of messages or repetitive attachments being locally stored. Correlate message volume with file creation activity in mail cache directories.
- AN1011 · Analytic 1011 — Monitor unified logs and Mail.app activity for repetitive incoming messages with attachments. Defenders should look for large volumes of incoming mail stored under ~/Library/Mail with unusual timing or repetitive subjects.
