Use when: abnormal case, abuse mailbox,\nuser reported email, reported phishing, case triage, case review, abnormal\ncases, abuse case management, phishing report, user submission, case\nremediation, or case judgment.</h2>\n<h1>Abnormal Security Abuse Mailbox Cases</h1>\n<h2>Overview</h2>\n<p>Abnormal Security's Abuse Mailbox automatically processes user-reported suspicious emails. When users forward or report emails to a designated abuse mailbox address, Abnormal analyzes the reported message and creates a case with an AI-generated judgment. This skill covers case lifecycle, triage workflows, remediation actions, and bulk operations.</p>\n<h2>Anti-triggers</h2>\n<ul>\n<li><strong>A compromised mailbox rather than a reported email</strong> — sign-in\nanomalies, new inbox rules, and session revocation have no surface on\nthis server at all; investigate identity in the M365 tenant, use\n<code>cipp-users</code>.</li>\n<li><strong>Threats Abnormal found on its own</strong> — no user reported them, so no\ncase exists; use <code>Abnormal Security Threats</code>.</li>\n<li><strong>User-reported phishing in a different platform</strong> — IRONSCALES runs\nits own report-to-incident loop from its Outlook and Gmail add-ins,\nwith separate IDs and its own classification verbs; use\n<code>IRONSCALES Incidents</code>.</li>\n<li><strong>A user who reported a simulated phish</strong> — campaign reporting rates\nbelong to the training platform; use <code>KnowBe4 Phishing</code>.</li>\n</ul>\n<h2>Case Lifecycle</h2>\n<pre><code>User Reports Email\n       |\n       v\n  Case Created (status: Open)\n       |\n       v\n  AI Analysis (judgment generated)\n       |\n       +---&gt; Malicious   ---&gt; Auto-Remediate (if configured)\n       |\n       +---&gt; Suspicious  ---&gt; Analyst Review Required\n       |\n       +---&gt; Spam         ---&gt; Auto-Dismiss (if configured)\n       |\n       +---&gt; Safe         ---&gt; Auto-Dismiss (if configured)\n       |\n       v\n  Analyst Action\n       |\n       +---&gt; Remediate (quarantine/delete across org)\n       |\n       +---&gt; Mark Not Spam (release to inbox)\n       |\n       +---&gt; Dismiss (close case, no action)\n       |\n       v\n  Case Closed (status: Done)\n</code></pre>\n<h2>Case Field Reference</h2>\n<h3>Core Fields</h3>\n<table>\n<thead>\n<tr>\n<th>Field</th>\n<th>Type</th>\n<th>Description</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>caseId</code></td>\n<td>number</td>\n<td>Unique case identifier — numeric, unlike <code>threatId</code></td>\n</tr>\n<tr>\n<td><code>severity</code></td>\n<td>string</td>\n<td>Severity level of the case</td>\n</tr>\n<tr>\n<td><code>affectedEmployee</code></td>\n<td>string</td>\n<td>Email address of the user who reported</td>\n</tr>\n<tr>\n<td><code>firstReported</code></td>\n<td>datetime</td>\n<td>When the case was first reported</td>\n</tr>\n</tbody>\n</table>\n<h3>Judgment Fields</h3>\n<table>\n<thead>\n<tr>\n<th>Field</th>\n<th>Type</th>\n<th>Description</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>overallStatus</code></td>\n<td>string</td>\n<td>Case status: Open, Acknowledged, Done</td>\n</tr>\n<tr>\n<td><code>judgmentStatus</code></td>\n<td>string</td>\n<td>AI judgment: Malicious, Spam, Safe, No Action Needed</td>\n</tr>\n<tr>\n<td><code>customerVisibleTime</code></td>\n<td>datetime</td>\n<td>When the case became visible in portal</td>\n</tr>\n</tbody>\n</table>\n<h3>Reported Message Fields</h3>\n<table>\n<thead>\n<tr>\n<th>Field</th>\n<th>Type</th>\n<th>Description</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>reportedMessage.subject</code></td>\n<td>string</td>\n<td>Subject of the reported email</td>\n</tr>\n<tr>\n<td><code>reportedMessage.senderAddress</code></td>\n<td>string</td>\n<td>Sender of the reported email</td>\n</tr>\n<tr>\n<td><code>reportedMessage.senderName</code></td>\n<td>string</td>\n<td>Display name of the sender</td>\n</tr>\n<tr>\n<td><code>reportedMessage.recipientAddress</code></td>\n<td>string</td>\n<td>Recipient of the reported email</td>\n</tr>\n<tr>\n<td><code>reportedMessage.receivedTime</code></td>\n<td>datetime</td>\n<td>When the reported email was received</td>\n</tr>\n<tr>\n<td><code>reportedMessage.attackType</code></td>\n<td>string</td>\n<td>Detected attack type (if malicious)</td>\n</tr>\n</tbody>\n</table>\n<h2>Case Judgments</h2>\n<table>\n<thead>\n<tr>\n<th>Judgment</th>\n<th>Description</th>\n<th>Recommended Action</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><strong>Malicious</strong></td>\n<td>Confirmed threat (BEC, phishing, malware)</td>\n<td>Remediate across organization</td>\n</tr>\n<tr>\n<td><strong>Spam</strong></td>\n<td>Unsolicited bulk email, marketing</td>\n<td>Dismiss or move to junk</td>\n</tr>\n<tr>\n<td><strong>Safe</strong></td>\n<td>Legitimate email, no threat detected</td>\n<td>Dismiss, notify user it is safe</td>\n</tr>\n<tr>\n<td><strong>No Action Needed</strong></td>\n<td>Phishing simulation or already remediated</td>\n<td>Dismiss</td>\n</tr>\n</tbody>\n</table>\n<h2>MCP Tools</h2>\n<p><strong>The cases domain is read-only.</strong> Two tools, both GETs. There is no tool\nthat changes a case's state, assigns it to an analyst, dismisses it, or\ncloses it. Case state changes happen in the Abnormal portal, not through\nthis server — an agent can read and reason about a case, then it has to\nhand the actual disposition to a human in the UI.</p>\n<table>\n<thead>\n<tr>\n<th>Tool</th>\n<th>Description</th>\n<th>Parameters</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td><code>abnormal_cases_list</code></td>\n<td>List cases</td>\n<td><code>pageSize</code> (default 100, max 100), <code>pageNumber</code> (1-indexed), <code>filter</code> (OData string)</td>\n</tr>\n<tr>\n<td><code>abnormal_cases_get</code></td>\n<td>Get one case by ID</td>\n<td><code>caseId</code> (required, <strong>number</strong>)</td>\n</tr>\n</tbody>\n</table>\n<p>There is no date-range parameter.

The neighbouring\n<code>threatId</code> used by <code>abnormal_threats_get</code> is a <strong>UUID string</strong>. Both are\ncalled \"the ID\" in conversation and they are not interchangeable; a\nthreat UUID passed to <code>abnormal_cases_get</code> is a type error, not a lookup\nmiss.</p>\n<p>The one action this server <em>can</em> take on the mail behind a case is\nmessage remediation, and it is reached through the threat, not the case:\n<code>abnormal_remediation_manage</code> needs a <code>threatId</code> and a <code>messageId</code>, and a\n<code>caseId</code> is neither.</p>\n<h3>Tool Usage Examples</h3>\n<p><strong>List cases from this month:</strong></p>\n<pre><code>{\n  \"tool\": \"abnormal_cases_list\",\n  \"parameters\": {\n    \"filter\": \"createdTime gt 2026-03-01T00:00:00Z\",\n    \"pageSize\": 25\n  }\n}\n</code></pre>\n<p><strong>Get case details:</strong></p>\n<pre><code>{\n  \"tool\": \"abnormal_cases_get\",\n  \"parameters\": {\n    \"caseId\": 12345\n  }\n}\n</code></pre>\n<h2>Triage Workflows</h2>\n<h3>Standard Triage Workflow</h3>\n<ol>\n<li><strong>List open cases</strong> - Get all cases with <code>overallStatus eq 'Open'</code></li>\n<li><strong>Sort by severity</strong> - Address critical and high severity first</li>\n<li><strong>Review AI judgment:</strong>\n<ul>\n<li>If Malicious: verify and remediate across organization</li>\n<li>If Spam: dismiss or move to junk</li>\n<li>If Safe: dismiss and respond to reporter</li>\n<li>If No Action Needed: dismiss (likely phishing simulation)</li>\n</ul>\n</li>\n<li><strong>Decide</strong> - produce the disposition and the evidence for it</li>\n<li><strong>Hand off</strong> - the case's own state (Open → Acknowledged → Done) can\nonly be changed in the Abnormal portal. If mail still needs pulling\nfrom inboxes, that runs through the threat:\n<code>abnormal_messages_list</code> then <code>abnormal_remediation_manage</code> per\nmessage.</li>\n</ol>\n<h3>Bulk Triage Workflow</h3>\n<ol>\n<li><strong>Filter cases by judgment</strong> - Start with cases judged as Malicious</li>\n<li><strong>Review Suspicious</strong> - Manually review cases without clear judgment</li>\n<li><strong>Batch the read, not the write</strong> - paginate <code>abnormal_cases_list</code> to\nbuild the full picture in one pass. There is no bulk case action to\nfollow it with; dispositions are entered in the portal one at a time.</li>\n</ol>\n<h3>Escalation Criteria</h3>\n<p>Escalate a case when:</p>\n<ul>\n<li>Multiple users report the same email</li>\n<li>The reported email impersonates an executive</li>\n<li>The email contains active malware or ransomware</li>\n<li>Credentials may have been entered on a phishing page</li>\n<li>The sender is a known vendor or partner (supply chain risk)</li>\n</ul>\n<h2>Case Actions — where they actually happen</h2>\n<p>The dispositions below are portal actions. None of them is an MCP tool,\nand none can be driven from this server.</p>\n<table>\n<thead>\n<tr>\n<th>Disposition</th>\n<th>Effect</th>\n<th>Where</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>Remediate</td>\n<td>Remove the email from recipients' inboxes</td>\n<td>Abnormal portal — or, per message, via <code>abnormal_remediation_manage</code> on the underlying threat</td>\n</tr>\n<tr>\n<td>Mark not spam</td>\n<td>Release email back to inbox</td>\n<td>Abnormal portal only</td>\n</tr>\n<tr>\n<td>Dismiss</td>\n<td>Close case without action</td>\n<td>Abnormal portal only</td>\n</tr>\n</tbody>\n</table>\n<p>The gap matters for automation design: an agent can fully triage the\nqueue from <code>abnormal_cases_list</code> and <code>abnormal_cases_get</code>, but the case\nstays Open until a human touches the portal. Write the handoff into the\nworkflow rather than assuming the agent closed anything.</p>\n<h2>Error Handling</h2>\n<h3>Common API Errors</h3>\n<table>\n<thead>\n<tr>\n<th>Code</th>\n<th>Message</th>\n<th>Resolution</th>\n</tr>\n</thead>\n<tbody>\n<tr>\n<td>400</td>\n<td>Invalid filter</td>\n<td>Check OData filter syntax</td>\n</tr>\n<tr>\n<td>401</td>\n<td>Unauthorized</td>\n<td>Check API token</td>\n</tr>\n<tr>\n<td>403</td>\n<td>Insufficient permissions</td>\n<td>Token needs abuse mailbox scope</td>\n</tr>\n<tr>\n<td>404</td>\n<td>Case not found</td>\n<td>Verify the case ID — and that you passed a numeric <code>caseId</code>, not a threat UUID</td>\n</tr>\n<tr>\n<td>429</td>\n<td>Rate limited</td>\n<td>Wait and retry</td>\n</tr>\n</tbody>\n</table>\n<h2>Best Practices</h2>\n<ol>\n<li><strong>Triage daily</strong> - Review abuse mailbox cases at least once per day</li>\n<li><strong>Trust the AI judgment</strong> - Abnormal's accuracy is high; use it to prioritize</li>\n<li><strong>Remediate every message, not \"the case\"</strong> - remediation is per message on the underlying threat; loop <code>abnormal_remediation_manage</code> and confirm each one, or you will leave the campaign half-pulled</li>\n<li><strong>Respond to reporters</strong> - Let users know their report was reviewed</li>\n<li><strong>Track phishing simulation reports</strong> - Monitor security awareness training effectiveness</li>\n<li><strong>Correlate with threats</strong> - Check if reported emails match known threat campaigns</li>\n<li><strong>Monitor false positive rate</strong> - High FP rates may indicate policy tuning needed</li>\n</ol>\n<h2>Related Skills</h2>\n<ul>\n<li><a href=\"../threats/SKILL.md\">Abnormal Threats</a> - Threat detection and analysis</li>\n<li><a href=\"../messages/SKILL.md\">Abnormal Messages</a> - Message analysis</li>\n<li><a href=\"../api-patterns/SKILL.md\">Abnormal API Patterns</a> - API authentication and usage</li>\n</ul>\n","files":[{"path":"SKILL.md","sizeBytes":9311,"isText":true}],"reviewScore":null,"reviewSummary":null,"trust":{"provenance":"trusted-source-unreviewed","notice":"Community-authored content, reproduced verbatim and not vetted as instructions.
