Consolidate 22 sibling repos into layered organism structure
Place useful parts of the surrounding repos into sica-fondt by layer, per the
body model (Ada = membrane; brain/endocrine/capabilities/knowledge non-Ada):

- brain/        LLM reasoning + providers (dapr, hermes, MoMoA)
- capabilities/ REPRAG sidecars: hermes tools/skills, dapr tools, parallel
                dispatch, A51 channels, and the OSINT cluster
- knowledge/    LORAG corpus: 754 cyber-skills, agency personas, secure-coding,
                MITRE ATT&CK data
- reference/    defensive threat-reference (C3, shhbruh doc) + AdaYaml parser

License handling: AGPL sources (worldosint, advanced_evolution, mercury,
Reticulum) and GPL DeTTECT are SPEC-only clean-room/port descriptions — no
copyleft code copied. MIT/Apache/data parts copied as working trees.

Safety: shhbruh escape/persistence material and C3 covert-C2 kept as reference
only, not wired into the running organism. See CONSOLIDATION.md.

Analyzing Office 365 Audit Logs for Compromise

Overview

Business Email Compromise (BEC) attacks often leave traces in Office 365 audit logs: suspicious inbox rule creation, email forwarding to external addresses, mailbox delegation changes, and unauthorized OAuth application consent grants. This skill uses the Microsoft Graph API to query the Unified Audit Log, enumerate inbox rules across mailboxes, detect forwarding configurations, and identify compromised account indicators.

When to Use

  • When investigating security incidents that require analyzing office365 audit logs for compromise
  • When building detection rules or threat hunting queries for this domain
  • When SOC analysts need structured procedures for this analysis type
  • When validating security monitoring coverage for related attack techniques

Prerequisites

  • Azure AD app registration with AuditLog.Read.All, MailboxSettings.Read, Mail.Read (application permissions)
  • Python 3.9+ with msal, requests
  • Client secret or certificate for authentication
  • Global Reader or Security Reader role

Steps

  1. Authenticate to Microsoft Graph using MSAL client credentials flow
  2. Query Unified Audit Log for suspicious operations (Set-Mailbox, New-InboxRule)
  3. Enumerate inbox rules across mailboxes and flag forwarding rules
  4. Detect mailbox delegation changes (Add-MailboxPermission)
  5. Identify OAuth consent grants to suspicious applications
  6. Check for suspicious sign-in patterns from audit logs
  7. Generate compromise indicator report with timeline

Expected Output

  • JSON report listing forwarding rules, delegation changes, OAuth grants, and suspicious audit events with risk scores
  • Timeline of compromise indicators with affected mailboxes
