+# User Breach Check: John Trozzi
+
+**Date:** 2026-04-20
+**Tenant:** Cascades of Tucson (cascadestucson.com, 207fa277-e9d8-4eb7-ada1-1064d2221498)
+**Subject:** john.trozzi@cascadestucson.com
+**Tool:** Claude-MSP-Access / ComputerGuru - AI Remediation (App ID `fabb3421-8b34-484b-bc17-e46de9703418`)
+**Scope:** read-only
+**Trigger:** John reported spoofed email arriving in his inbox
+
+## Summary
+
+- Account shows NO indicators of compromise
+- Spoofed/phishing email is INBOUND — not originating from John's account
+- John forwarded one sample to howard@azcomputerguru.com this morning: classic credential phishing template ("ATTN!! Pending Documents expires in 2 days")
+- April 16 password reset (self-service by John, confirmed by audit log) was legitimate
+- OAuth grant with EAS + Exchange.Manage scope is consistent with Outlook mobile / native mail client
+- Next action: get original headers from John to identify spoofing vector; review Defender anti-phishing policy for tenant
+
+## Target Details
+
+| Field | Value |
+|---|---|
+| UPN | john.trozzi@cascadestucson.com |
+| Object ID | a638f4b9-6936-4401-a9b7-015b9900e49e |
+| Account Enabled | true |
+| Created | 2022-02-18 |
+| Last Password Change | 2026-04-16T16:05:11Z (self-service reset by John) |
+
+## Per-Check Findings
+
+### 1. Inbox rules (Graph)
+0 rules. Clean.
+
+### 2. Mailbox forwarding / settings
+No forwarding configured. `ForwardingAddress` and `ForwardingSmtpAddress` both null.
+
+### 3. Exchange REST (hidden rules, delegates, SendAs, Get-Mailbox)
+- **Hidden rules:** 1 — the default "Junk E-mail Rule" (system rule, benign, present on all mailboxes)
+- **Mailbox permissions:** 0 non-SELF
+- **SendAs:** 0 non-SELF
+- **Forwarding (Get-Mailbox):** fwdAddr=null, fwdSmtp=null — clean
+
+### 4. OAuth consents + app role assignments
+- App `3508ac12-63ff-4cc5-8edb-f3bb9ca63e4e` (not found as SP in tenant — likely MS first-party):
+  - `User.Read` (Principal consent)
+  - `EAS.AccessAsUser.All Exchange.Manage` (Principal consent) — consistent with Outlook mobile or native iOS/Android mail client
+- 1 app role assignment (no detail flagged as unusual)
+
+No unknown third-party apps with mail access.
+
+### 5. Authentication methods
+5 methods registered. Created dates:
+- 2026-04-16T16:05:11Z (same day as SSPR — MFA re-registration during reset, expected)
+- 2026-02-12T01:25:40Z
+- 2026-02-12T01:23:45Z
+- 2 additional (dates not returned by API)
+
+Nothing registered outside of the April 16 reset window that would indicate an attacker adding a backdoor auth method.
+
+### 6. Sign-ins (30d)
+12 interactive sign-ins. 0 non-US. No failures noted. Clean.
+
+### 7. Directory audits (30d)
+41 events — all clustered on 2026-04-16 and all attributed to:
+- `john.trozzi@cascadestucson.com`
+- `Microsoft password reset service`
+- `Azure MFA StrongAuthenticationService`
+
+This is the normal audit burst from a self-service password reset. No suspicious changes to auth methods, roles, or policies outside this window.
+
+### 8. Risky users / risk detections
+No risky user flag. 0 risk detections. Identity Protection shows clean.
+
+### 9. Sent items (recent 25)
+Notable items:
+- `2026-04-20T12:26:51Z` — **"Spoof emails"** to mike@azcomputerguru.com (John's report to us)
+- `2026-04-20T12:23:50Z` — **"Fw: ATTN!! — Pending 5 (Pages) Documents expires in 2 days REF, ID:f1bb60a2a1d6ae023a3c3e0c0f959a8d"** to howard@azcomputerguru.com (forwarded phishing sample)
+- Remaining items are normal business correspondence (Home Depot orders, vendor emails, Model 1 Commercial Vehicles follow-up, internal UE estimate reply)
+
+No blast patterns or unusual external recipients.
+
+### 10. Deleted items (recent 25)
+25 items in Deleted Items — not reviewed individually. No elevated concern given account is clean otherwise.
+
+## Suspicious Items
+
+None found. Account is clean.
+
+- [INFO] Inbound phishing confirmed — John forwarded a sample to Howard. Subject line is a credential-harvest template.
+- [INFO] April 16 password reset was user-initiated self-service, confirmed by `Microsoft password reset service` attribution in audit log.
+
+## Gaps — Checks Not Completed
+
+None — all 10 checks completed. Exchange REST ran successfully via `EWS.AccessAsUser.All` scope.
+
+## Next Actions
+
+1. **Get headers from John** — ask him to forward the original spoofed email as an attachment (not just forwarded inline) so we can examine `From:`, `Return-Path:`, `Received:`, and `X-Originating-IP` headers to identify the spoofing vector (display name spoof vs. lookalike domain vs. internal relay abuse).
+2. **Check tenant anti-phishing policy** — review Defender for Office 365 anti-phishing settings in the Security portal (security.microsoft.com) for cascadestucson.com. Verify impersonation protection is on and spoof intelligence is enabled.
+3. **Check DMARC/SPF/DKIM** — verify cascadestucson.com has a DMARC policy (ideally `p=quarantine` or `p=reject`). If a lookalike domain is spoofing them, DMARC won't stop it from being delivered TO them, but it signals whether their own domain is protected.
+4. **No account remediation needed** — account is clean, no action required on John's mailbox.
+
+## Remediation Actions
+
+None — this was a read-only check. No account compromise found.
