# Session Log — 2026-04-20 ## User - **User:** Mike Swanson (mike) - **Machine:** DESKTOP-0O8A1RL - **Role:** admin ## Session Summary This session continued from a previous context that ran out of window. It covered two bodies of work: 1. **Remediation skill complete rewrite** — Updated all skill files to reflect the new 5-app tiered Entra architecture (Security Investigator, Exchange Operator, User Manager, Tenant Admin, Defender Add-on) replacing the old single over-permissioned app. 2. **Cascades Tucson breach check on John Trozzi** — Ran a full 10-point breach check after John reported spoofed email in his inbox. Mailbox confirmed clean; incident is inbound phishing, not account compromise. --- ## Work 1: Remediation Skill Rewrite ### Context (from prior session — summarized) Previous session built out the full tiered MSP Entra app architecture: - Created all 5 apps + management app via ComputerGuru-Management SP - Granted admin consent in Grabblaw for Security Investigator + User Manager - Old app `fabb3421` (ComputerGuru - AI Remediation) had 159 permissions including Defender ATP, which broke consent on tenants without MDE license (AADSTS650052) ### Files Rewritten **`D:/claudetools/.claude/skills/remediation-tool/scripts/get-token.sh`** - Completely rewritten: accepts ` ` instead of ` ` - Tiers: `investigator` | `investigator-exo` | `exchange-op` | `user-manager` | `tenant-admin` | `defender` - Each tier maps to correct CLIENT_ID, vault SOPS path, and resource scope URL - Cache key is now `{tenant}/{tier}.jwt` (not `{tenant}/{scope}.jwt`) - Falls back through both `credentials.client_secret` and `credentials.credential` field names - Falls back to raw sops+python if vault.sh fails **`D:/claudetools/.claude/skills/remediation-tool/SKILL.md`** - Added full app tier table with App IDs and vault files - Updated Exchange REST prerequisites to name correct SP per operation - Added minimum-privilege guidance ("never use tenant-admin for read-only check") **`D:/claudetools/.claude/commands/remediation-tool.md`** - Rewrote token acquisition to use tier flags - Added per-app consent URLs in correct format (`redirect_uri=https://azcomputerguru.com`) - Added `disable-smtp-auth` action - Mapped each remediation action to its correct app tier (Exchange Operator for EXO write, User Manager for user ops) **`D:/claudetools/.claude/skills/remediation-tool/references/gotchas.md`** - Full rewrite: 5-app suite table, per-app consent URLs, directory role map updated - Tenant table updated: Grabblaw now shows Security Investigator + User Manager consented (2026-04-20) - Migration note for Valleywide/Dataforth/Cascades (still on old app) - AADSTS650052 note for Defender tier on non-MDE tenants **`D:/claudetools/.claude/skills/remediation-tool/references/checklist.md`** - False-positive filter updated to match any "ComputerGuru" app display name **`D:/claudetools/.claude/skills/remediation-tool/references/graph-endpoints.md`** - Added token acquisition block at top with tier variable mapping - Exchange REST section now distinguishes `$EXO_R` (Security Investigator) from `$EXO_W` (Exchange Operator) ### Vault Field Name Note New SOPS files for the 5 apps were created in previous session. The field name for client secrets may be `credentials.client_secret` or `credentials.credential`. The updated `get-token.sh` tries both. If neither works on first use, check field with: ```bash bash D:/vault/scripts/vault.sh get msp-tools/computerguru-security-investigator.sops.yaml ``` --- ## Work 2: Cascades Tucson — John Trozzi Breach Check ### Trigger John reported "spoofed email in his inbox." He forwarded the phishing email to howard@azcomputerguru.com and emailed Mike at 12:26 UTC with subject "Spoof emails." ### Approach Note Cascades Tucson still uses the OLD app (`fabb3421`) — the new Security Investigator hasn't been consented there yet. Used old app credentials from vault (`msp-tools/claude-msp-access-graph-api.sops.yaml`) for this investigation. ### Tenant - **Domain:** cascadestucson.com - **Tenant ID:** `207fa277-e9d8-4eb7-ada1-1064d2221498` - **App used:** fabb3421 (old app, still active at Cascades) ### User - **UPN:** john.trozzi@cascadestucson.com - **User ID:** a638f4b9-6936-4401-a9b7-015b9900e49e - **Last password change:** 2026-04-16T16:05:11Z (self-service, after April 16 remediation) ### 10-Point Results — All Clean | Check | Result | |---|---| | Graph inbox rules | CLEAN — no custom rules | | Exchange REST rules (incl. hidden) | CLEAN — Junk E-mail Rule only | | Mailbox forwarding | CLEAN — null/false on all fields | | Delegates / FullAccess | CLEAN — no non-SELF | | SendAs grants | CLEAN — no non-SELF | | OAuth consents | CLEAN — BlueMail (2022) + EAS, both legitimate | | Auth methods | NOTE — duplicate Authenticator (SM-F731U null date), low risk | | Sign-ins 30d | CLEAN — all US/Phoenix, IP 184.191.143.62, no foreign access | | Risky user | CLEAN — riskLevel: none | | Directory audits | EXPECTED — April 16 sysadmin reset cycle + John self-service pw change | ### Incident Finding John received phishing email: - **Subject:** "ATTN!! — Pending 5 (Pages) Documents expires in 2 days REF, ID:f1bb60a2a1d6ae023a3c3e0c0f959a8d" - Classic credential-harvesting lure - John correctly identified it, forwarded to Howard, reported to Mike - No evidence of link click or credential entry - Original email no longer in inbox/deleted — John deleted it ### Google Account Alert John received a security alert (16:01 UTC today) from no-reply@accounts.google.com for `201cascades@gmail.com`. Possibly a shared facility account. Confirm it has 2FA. ### DMARC Finding ``` _dmarc.cascadestucson.com: v=DMARC1;p=none;pct=100;rua=mailto:info@cascadestucson.com cascadestucson.com SPF: v=spf1 ip4:72.194.62.5 include:spf.protection.outlook.com -all ``` - SPF is tight (`-all`) — good - DMARC is `p=none` — monitoring only, no enforcement. Phishing emails can land in inboxes - **Action needed:** Upgrade to `p=quarantine` after confirming DKIM. Coordinate with Meredith. ### Recommendations 1. Confirm John didn't click anything or enter credentials (if he did: revoke-sessions + password-reset) 2. Howard should delete the forwarded phishing email without clicking 3. Upgrade DMARC to p=quarantine (coordinate with Meredith) 4. Confirm DKIM is configured for cascadestucson.com in Exchange Online 5. Verify 201cascades@gmail.com Google alert 6. Clean up duplicate Authenticator entry (SM-F731U, null date) — low priority ### Report Location `D:/claudetools/clients/cascades-tucson/reports/2026-04-20-breach-check-john-trozzi.md` Committed: db157e3 --- ## Credentials Reference (from prior session — carried forward) ### ComputerGuru-Management App (ACG home tenant) - **App ID:** `0df4e185-4cf2-478c-a490-cc4ef36c6118` - **Tenant ID:** `ce61461e-81a0-4c84-bb4a-7b354a9a356d` - **Secret:** `C8t8Q~.bN-q5kJ~ARhkK3oMgg~w6pQhRq3-IKc15` - **Vault:** `D:/vault/msp-tools/computerguru-management.sops.yaml` - **Permissions:** Application.ReadWrite.All, AppRoleAssignment.ReadWrite.All, User.Read.All ### ComputerGuru Security Investigator (multi-tenant, read-only breach checks) - **App ID:** `bfbc12a4-f0dd-4e12-b06d-997e7271e10c` - **Secret:** `LS28Q~wHInqBB1y1TOWfwamKHBz~D2IFeSyUCcb0` - **Vault:** `D:/vault/msp-tools/computerguru-security-investigator.sops.yaml` - **Tenants consented:** Grabblaw (032b383e) — Security Investigator + Exchange Admin role needed - **Note:** NOT YET CONSENTED at Cascades, Dataforth, Valleywide — still using old app there ### ComputerGuru Exchange Operator (multi-tenant, EXO write) - **App ID:** `b43e7342-5b4b-492f-890f-bb5a4f7f40e9` - **Secret:** `Ct28Q~fKYUu.RvkMaGNAV1YeK6h-HBewCTPnwa.Y` - **Vault:** `D:/vault/msp-tools/computerguru-exchange-operator.sops.yaml` ### ComputerGuru User Manager (multi-tenant, user/group write) - **App ID:** `64fac46b-8b44-41ad-93ee-7da03927576c` - **Secret:** `GEQ8Q~Xl0_Lrbq85QjEyUsvK9rMe1m-C.ze.0ahN` - **Vault:** `D:/vault/msp-tools/computerguru-user-manager.sops.yaml` - **Tenants consented:** Grabblaw (032b383e) ### ComputerGuru Tenant Admin (multi-tenant, high-privilege) - **App ID:** `709e6eed-0711-4875-9c44-2d3518c47063` - **Secret:** `GYe8Q~I-hzqK1hUsh2uUg6RVFwM1TQt8C7h8XaUm` - **Vault:** `D:/vault/msp-tools/computerguru-tenant-admin.sops.yaml` ### ComputerGuru Defender Add-on (multi-tenant, MDE only) - **App ID:** `dbf8ad1a-54f4-4bb8-8a9e-ea5b9634635b` - **Secret:** `r1h8Q~L4kPb3STTjazbxNDsYw3JuHm1yIhTy5bqM` - **Vault:** `D:/vault/msp-tools/computerguru-defender-addon.sops.yaml` ### Old App (DEPRECATED — still active at Cascades/Dataforth/Valleywide) - **App ID:** `fabb3421-8b34-484b-bc17-e46de9703418` - **Display name:** ComputerGuru - AI Remediation - **Vault:** `D:/vault/msp-tools/claude-msp-access-graph-api.sops.yaml` → field: `credentials.credential` - **Status:** Retire after migrating remaining tenants to new app suite ### Mike's Entra User ID (for app ownership) - **Object ID:** `f34ebe40-9565-4135-af4c-2e808df57a25` - **ACG Tenant:** `ce61461e-81a0-4c84-bb4a-7b354a9a356d` ### Grabblaw - **Tenant ID:** `032b383e-96e4-491b-880d-3fd3295672c3` - **Svetlana Larionova:** slarionova@grabblaw.com (created 2026-04-20, temp pw: TempGrabb2026!, User ID: affab40c-5535-4c1a-9a78-a2eda1a4a3b7) - **License:** M365 Business Premium (f245ecc8-75af-4f8e-b61f-27d8114de5f3) - **Apps consented:** Security Investigator, User Manager - **Directory roles:** none assigned yet (no Exchange Admin on either SP) ### Cascades Tucson - **Tenant ID:** `207fa277-e9d8-4eb7-ada1-1064d2221498` - **Apps:** Still using old app fabb3421.

Extracted verbose sections to on-demand reference files. No functional changes — same rules, smaller footprint. ### Changes Made **`.claude/CLAUDE.md`** — 494 lines → 252 lines (~49% reduction) - Work Mode section: replaced 22-line narrative with a 5-row detection table; dropped color references (color changes don't work programmatically anyway — mode.md handles that) - PROJECT_STATE.md Action Protocol: removed entirely (~65 lines) — moved to dedicated file - Ollama section: trimmed from ~90 lines to 5-line summary + pointer - Auto Context Loading: removed Benefits list, condensed anti-pattern examples to one sentence - Credential Access: kept the 4 vault commands, removed encryption/key location details **`.claude/OLLAMA.md`** — new file (67 lines) - Full Ollama reference: endpoints, models, connection examples, review policy - Only loaded when Claude needs to call Ollama (Tier 0 tasks) **`.claude/PROJECT_STATE_PROTOCOL.md`** — new file (42 lines) - Full locking protocol: what requires a lock, how to claim/release, stale lock rule - Only loaded when Auto Context Loading finds a PROJECT_STATE.md in a project ### Decisions - PROJECT_STATE files already have brief locking instructions embedded in their headers — the full protocol in CLAUDE.md was redundant - Work mode colors were dropped from CLAUDE.md because `/color` is a CLI built-in Claude can't invoke programmatically; mode.md already has the authoritative detail - Ollama extraction was the biggest single win (~90 lines) — it's only needed for Tier 0 delegation, not every session ### Pending - None. This was a self-contained optimization pass. --- ## Key Infrastructure Reference | Resource | Details | |---|---| | IX Web Hosting | 172.16.3.10 (ext: 72.194.62.5) WHM port 2087 | | cPanel user | azcomputerguru | | WP DB | azcomputerguru_acg2025, table prefix Lvkai5BQ_, mike/TempWP2026! | | ClaudeTools API | http://172.16.3.30:8001 | | GuruRMM server | 172.16.3.30:3001 | | Gitea | http://172.16.3.20:3000 (internal) | | ACG Tenant | ce61461e-81a0-4c84-bb4a-7b354a9a356d |
