We got results. Key findings:1. **Shelly Dooley - Shelly@bgbuildersllc.com**
2. Account Enabled: True
3. Created: June 3, 2023
4. Last Password Change: **April 15, 2025** - That's 8 months ago, which is fairly recent but not super recent.
5. **No inbox rules configured** - This is good, no malicious forwarding rules
6. No sign-in logs found - This could mean no Azure AD Premium, or no recent sign-insHowever, some things couldn't be retrieved (mail folders and sent items). This might be due to permissions. Let me check what we can do.

The lack of sign-in logs is concerning - we can't see login activity without Azure AD Premium P1/P2.

Let me try to get more data, specifically:1. Check for recent sign-ins via different methods
2. Check forwarding settings at the mailbox level (different from inbox rules)3. Try Exchange Online for better mailbox accessLet me try Exchange Online admin center approach or see if we can get more detailed info.


**Initial Findings for Shelly Dooley (Shelly@bgbuildersllc.com):**

| Item | Status |
|------|--------|
| Account | **Enabled** |
| Created | June 3, 2023 |
| Last Password Change | **April 15, 2025** |
| Inbox Rules | **None found** (good - no forwarding rules) |
| Sign-in Logs | Not available (requires Azure AD Premium) |

The inbox rules check is clean - no malicious forwarding. However:
- Mail folders and sent items didn't return data (permission issue)
- No sign-in logs without Azure AD Premium P1/P2

Let me try Exchange Online for more mailbox details (forwarding at mailbox level is different from inbox rules).

Let me launch the Exchange Online investigation script in an interactive window.


Bash

powershell.exe -Command "Start-Process powershell.exe -ArgumentList '-NoExit','-ExecutionPolicy','Bypass','-File','C:\Users\MikeSwanson\claude-projects\exo-shelly.ps1'"

Launch EXO investigation window


A new PowerShell window should have opened for Exchange Online. This will check:
1. Mailbox-level forwarding (different from inbox rules)
2. Inbox rules via Exchange3. Mailbox statistics (last logon)
4. Message trace (sent/received)
5. Mailbox permissions
6. Send-As permissionsLet me wait for the results.


New window opened for Exchange Online investigation. This checks:
- Mailbox-level forwarding settings
- Message trace (sent/received emails)
- Mailbox permissions & Send-As rights
- Last logon time

Authenticate when prompted. Let me check for results:


powershell.exe -Command "Start-Sleep -Seconds 60; if (Test-Path 'C:\Users\MikeSwanson\claude-projects\shelly-exo-results.txt') { Get-Content 'C:\Users\MikeSwanson\claude-projects\shelly-exo-results.txt' } else { 'Results not ready yet - still authenticating or running' }" 2>&1

Wait and read EXO results

## Investigation Complete: Shelly Dooley (Shelly@bgbuildersllc.com)

### Summary

| Check | Result |
|-------|--------|
| **Mailbox Forwarding** | None configured |
| **Inbox Rules** | None configured |
| **Send-As Permissions** | None granted |
| **Mailbox Permissions** | Normal (no suspicious access) |
| **Account Status** | Enabled |
| **Last Password Change** | April 15, 2025 |

### Mailbox Stats
- **17,256 items** (12.42 GB)
- **Last Logon:** Today at 14:02:10

### Message Trace
- No sent messages in last 10 days
- No received messages in last 3 days

### Findings
**No active compromise indicators found:**
- No email forwarding rules (inbox or mailbox level)
- No suspicious permissions
- No delegation/send-as configured

**However:** Sign-in logs aren't available without Azure AD Premium P1/P2. If you suspect unauthorized access, you'd need:
1. Azure AD Premium for sign-in logs
2. Microsoft Defender for Office 365 for threat investigation

**What triggered the concern?** Did someone report suspicious emails from this account, or was there a specific incident? That context would help determine next steps.


She received an email from herself, phishing attempt.


Looking at this screenshot, this is a classic spoofed email phishing attempt. Key observations:

1. **The email appears to be from "shelly@bgbuildersllc.com"** - but it's TO Shelly Dooley, so it looks like she sent it to herself

2. **Subject:** "Sonorangreenllc.com New Notice: All Employee Stipend..." - mentions sonorangreenllc.com which is the related company in the same tenant

3. **Key indicator:** "We could not verify the identity of the sender. Click here to learn more." - This is Microsoft 365's warning that the sender failed authentication (SPF/DKIM/DMARC)

4. **Attachment:** "Shelly_Bonus.pdf" (52 KB) - Classic phishing lure with personalized filename

5. **Retention Policy shows "Junk Email (30 days)"** - M365 correctly classified this as junk

This is **email spoofing**, not account compromise. The attacker:
- Spoofed the From address to appear as shelly@bgbuildersllc.com
- Sent from an external server that doesn't have permission to send as that domain
- M365 caught it because SPF/DKIM/DMARC checks failed

This is actually GOOD news - it means Shelly's account wasn't compromised. The attacker just forged the From header.

I should:
1. Explain this is spoofing, not compromise
2. Check the domain's DMARC/SPF/DKIM configuration to see if it can be hardened
3. Recommend they set DMARC to reject/quarantine if not already


**Good news - this is NOT account compromise.** This is email **spoofing**.

## What's Happening

The attacker **forged the "From" address** to look like it came from Shelly. Key evidence:

1. **"We could not verify the identity of the sender"** - Microsoft detected the forgery
2. **Landed in Junk** - M365 correctly classified it as suspicious
3. **Our investigation showed no forwarding rules or unauthorized access**

The attacker sent this from an external server, just putting "shelly@bgbuildersllc.com" in the From field. They don't have access to her account.

## The Phish

- **Lure:** "Employee Stipend" / "Shelly_Bonus.pdf"
- **Target:** Tricking her into opening the PDF (likely contains malware or credential harvesting link)

## Recommended Actions

Let me check your domain's email authentication (SPF/DKIM/DMARC) - if DMARC is set to "none" or "quarantine", we should harden it to "reject" to block these spoofed emails:


Bash

nslookup -type=txt _dmarc.bgbuildersllc.com 2>&1 && echo "---" && nslookup -type=txt bgbuildersllc.com 2>&1 | head -30

Check DMARC and SPF records


*** UnKnown can't find _dmarc.bgbuildersllc.com: Non-existent domain

Server:  UnKnown
Address:  fde7:f3af:96b1:10::1

---
Non-authoritative answer:

Server:  UnKnown
Address:  fde7:f3af:96b1:10::1

bgbuildersllc.com	text =

	"v=spf1 include:spf.protection.outlook.com -all"


Found the issue:

1. **SPF:** `v=spf1 include:spf.protection.outlook.com -all` - This is good! Hard fail (-all) for unauthorized senders

2. **DMARC:** No DMARC record exists! This is a problem. Without DMARC, even though SPF fails, receiving servers don't know to reject the message.

I should recommend:
1. Add a DMARC record
2. Set it to reject policy so spoofed emails are blocked

Let me also check DKIM.


**Found the problem:**

| Record | Status |
|--------|--------|
| **SPF** | ✅ Good: `v=spf1 include:spf.protection.outlook.com -all` |
| **DMARC** | ❌ **Missing!** No DMARC record |

Without DMARC, receiving servers don't know to **reject** spoofed emails - they just flag them as suspicious (which is why it went to Junk instead of being blocked).

## Fix: Add DMARC Record

Add this DNS TXT record to bgbuildersllc.com:

```
Host: _dmarc
Type: TXT
Value: v=DMARC1; p=reject; rua=mailto:dmarc@bgbuildersllc.com
```

This tells all mail servers: **Reject any email claiming to be from bgbuildersllc.com that fails SPF/DKIM checks.**

Where is the DNS hosted - Microsoft 365, Cloudflare, GoDaddy, or elsewhere? I can help add the record.

## Immediate Actions
1. **Tell Shelly:** Her account is NOT compromised - don't click the PDF
2. **Delete the phishing email** from her Junk folder
3. **Add DMARC** to prevent future spoofing
4. **Consider:** Security awareness training about spoofed emails


We have access to their godaddy account for modifications.


The user wants me to help add the DMARC record to their GoDaddy DNS. I can guide them through the GoDaddy DNS management interface, or if they have API credentials, I could potentially do it programmatically.

Let me ask how they want to proceed - either I can give them the steps to add it manually, or if they have GoDaddy API access, I could help automate it.

Actually, the simplest approach is to just give them the exact record to add and guide them through the GoDaddy interface. Let me provide clear instructions.


Let's add the DMARC record. Here's exactly what to add in GoDaddy:

## GoDaddy DNS Settings

**Go to:** GoDaddy → My Products → bgbuildersllc.com → DNS → Add Record

| Field | Value |
|-------|-------|
| **Type** | TXT |
| **Name** | _dmarc |
| **Value** | `v=DMARC1; p=reject; rua=mailto:sysadmin@bgbuildersllc.com` |
| **TTL** | 1 Hour |

Click **Save**.

---

Also check if they have DKIM enabled in M365. Let me verify:


nslookup -type=cname selector1._domainkey.bgbuildersllc.com 2>&1 && echo "---" && nslookup -type=cname selector2._domainkey.bgbuildersllc.com 2>&1

Check DKIM selectors


*** UnKnown can't find selector1._domainkey.bgbuildersllc.com: Non-existent domain

Server:  UnKnown
Address:  fde7:f3af:96b1:10::1

---
*** UnKnown can't find selector2._domainkey.bgbuildersllc.com: Non-existent domain

Server:  UnKnown
Address:  fde7:f3af:96b1:10::1


DKIM is also not configured. This is important - without DKIM, emails can be spoofed more easily. Let me provide the full set of records to add including DKIM.For Microsoft 365, the DKIM CNAME records are:
- selector1._domainkey.bgbuildersllc.com → selector1-bgbuildersllc-com._domainkey.bgbuildersllc.onmicrosoft.com
- selector2._domainkey.bgbuildersllc.com → selector2-bgbuildersllc-com._domainkey.bgbuildersllc.onmicrosoft.comActually, I need to know their onmicrosoft.com domain name. Looking at the tenant info earlier, the tenant ID was ededa4fb-f6eb-4398-851d-5eb3e11fab27. But I don't know the .onmicrosoft.com domain name.For now, let me provide the general format and note they need to enable DKIM in M365 admin center which will give them the exact CNAME values.


**DKIM is also missing!** You need both DMARC and DKIM for full protection.

## Complete DNS Records to Add in GoDaddy

### 1. DMARC Record
| Type | Name | Value |
|------|------|-------|
| TXT | _dmarc | `v=DMARC1; p=reject; rua=mailto:sysadmin@bgbuildersllc.com` |

### 2. DKIM Records (for Microsoft 365)
| Type | Name | Value |
|------|------|-------|
| CNAME | selector1._domainkey | `selector1-bgbuildersllc-com._domainkey.bgbuildersllc.onmicrosoft.com` |
| CNAME | selector2._domainkey | `selector2-bgbuildersllc-com._domainkey.bgbuildersllc.onmicrosoft.com` |

**Note:** The DKIM target may vary - to get the exact values:
1. Go to **Microsoft 365 Defender** → https://security.microsoft.com
2. **Email & collaboration** → **Policies & rules** → **Threat policies**
3. **Email authentication settings** → **DKIM**
4. Select **bgbuildersllc.com** → It will show the exact CNAME records needed

---

Want me to walk you through adding these in GoDaddy, or do you want to grab the exact DKIM values from M365 first?


Getting items from MS


The user is getting the DKIM values from Microsoft 365. I'll wait for them to provide the information or let me know when they're ready to proceed.


Got it - let me know when you have the DKIM CNAME values from M365 Defender and I'll help you add everything to GoDaddy.

While you're in there, the path is:
**security.microsoft.com → Email & collaboration → Policies & rules → Threat policies → Email authentication settings → DKIM → bgbuildersllc.com**

It should show two CNAME records (selector1 and selector2) with the exact target values to use.


Host Name : selector1._domainkey
Points to address or value: selector1-bgbuildersllc-com._domainkey.sonorangreenllc.onmicrosoft.com

Host Name : selector2._domainkey
Points to address or value: selector2-bgbuildersllc-com._domainkey.sonorangreenllc.onmicrosoft.com


Good - the user got the DKIM records from Microsoft 365. Interesting that the onmicrosoft.com domain is sonorangreenllc.onmicrosoft.com (the other company in the tenant), not bgbuildersllc.onmicrosoft.com. This makes sense since it's a shared tenant.

Now I can provide the complete list of DNS records to add in GoDaddy.


Got it. Here's the complete list for GoDaddy:

## DNS Records to Add - bgbuildersllc.com

### DKIM (2 CNAME records)

| Type | Name | Points to | TTL |
|------|------|-----------|-----|
| CNAME | selector1._domainkey | `selector1-bgbuildersllc-com._domainkey.sonorangreenllc.onmicrosoft.com` | 1 Hour |
| CNAME | selector2._domainkey | `selector2-bgbuildersllc-com._domainkey.sonorangreenllc.onmicrosoft.com` | 1 Hour |

### DMARC (1 TXT record)

| Type | Name | Value | TTL |
|------|------|-------|-----|
| TXT | _dmarc | `v=DMARC1; p=reject; rua=mailto:sysadmin@bgbuildersllc.com` | 1 Hour |

---

**After adding in GoDaddy:**
1. Wait ~5-10 minutes for DNS propagation
2. Go back to M365 Defender → DKIM → bgbuildersllc.com
3. Click **Enable** to turn on DKIM signing

Let me know when the records are added and I'll verify they're live.


save session to gitea


The user wants to save the session and sync to Gitea. Based on the CLAUDE.md, I should use the /save command which saves to session-logs. Let me create a session log for today's work and then commit/push to Gitea.

Good, there's already a session file for today. I need to append the new work done in this session:
1. Connected Windows machine to Gitea repo
2. Removed WSL from this machine
3. Investigated shelly@bgbuildersllc.com compromise
4. Found it was email spoofing (not account compromise)
5. Added BG Builders LLC M365 credentials
6. Configured DMARC and DKIM records for bgbuildersllc.com

Let me update the session file with this information.

| `_dmarc.rrs-law.com` | TXT | `v=DMARC1; p=quarantine; rua=mailto:admin@rrs-law.com` |
| `selector1._domainkey.rrs-law.com` | CNAME | `selector1-rrslaw-com0i._domainkey.rrslaw.d-v1.dkim.mail.microsoft` |
| `selector2._domainkey.rrs-law.com` | CNAME | `selector2-rrslaw-com0i._domainkey.rrslaw.d-v1.dkim.mail.microsoft` |

### Final Email DNS Status for rrs-law.com

| Record | Status |
|--------|--------|
| MX → M365 | ✅ |
| SPF (includes M365) | ✅ |
| DMARC | ✅ NEW |
| Autodiscover | ✅ |
| DKIM selector1 | ✅ NEW |
| DKIM selector2 | ✅ NEW |
| MS Verification | ✅ |
| Enterprise Registration | ✅ |
