|
||
292→
|
||
293→### Ticket: Phishing Attempt - Determine Entrypoint and Resolve
|
||
294→
|
||
295→### Actions Completed
|
||
296→
|
||
297→#### 1. Deleted "true" App Registration
|
||
298→- **App ID:** a21e971d-1fcb-41a7-9b01-c45b8d7d1754
|
||
299→- **Action:** Manually deleted in Entra ID by admin
|
||
300→- **Reason:** Unused app with Mail.Read/Mail.Send permissions, created by internal user but never used
|
||
301→
|
||
302→#### 2. Deleted Phishing Emails from All Mailboxes
|
||
303→Used Graph API to search and delete phishing emails across all 148 user mailboxes.
|
||
304→
|
||
305→**Emails Deleted:**
|
||
306→| Mailbox | Subject | Campaign |
|
||
307→|---------|---------|----------|
|
||
308→| jlohr@dataforth.com | Please Review: Dataforth corporation 2026 Updated Pay Structure & Appraisal Guidelines ID-ssEcpoQ1EQ | January 2026 |

314→| croedig@dataforth.com | Dataforth corporation – December Bonus and Allocation for All Staff | December 2025 |
|
||
315→
|
||
316→**Total: 10 phishing emails deleted**
|
||
317→
|
||
318→Internal discussion threads (RE:/FW: emails) were preserved for audit trail.
|
||
319→
|
||
320→#### 3. Configured Exchange Online Mail Flow Protection
|
||
321→
|
||
322→**Root Cause:** Phishing emails bypassed MailProtector by connecting directly to M365's MX endpoint (`dataforth-com.mail.protection.outlook.com`) instead of routing through the MX records pointing to MailProtector.
|
||
323→
|
||
324→**Solution Implemented:**
|
||
325→
|
||
326→**A. Inbound Connector Created**
|
||
327→- **Name:** MailProtector Inbound
|
||
328→- **Type:** Partner organization → Office 365
|
||
329→- **Sender IPs:** 52.0.31.31, 52.0.74.211, 52.0.70.91
|
||
330→
|
||
331→**B. Transport Rule Created**
|
||
332→- **Name:** Mailptroctor Only (Reject Direct Mail)
|
||
333→- **Priority:** 0 (highest)
|
||
334→- **Mode:** Enforce
|
||
335→- **Condition:** Sender is located 'NotInOrganization' (external)
|
||
336→- **Action:** Reject with explanation "Direct Mail Not Allowed - Please route through MX" (status code 5.7.1)
|
||
337→- **Exception:** Sender IP is in range 52.0.70.91, 52.0.74.211, or 52.0.31.31
|
||
338→
|
||
339→**Testing Results:**
|
||
340→- SMTP connection to M365 still accepts messages at protocol level (normal behavior)
|
||
341→- Transport rule rejects messages during processing - they never reach inbox
|
||
342→- Verified by sending test emails from non-MailProtector IP - none delivered
|
||
343→

346→### Attack Summary
|
||
347→
|
||
348→| Campaign | Date | Subject Pattern | Method |
|
||
349→|----------|------|-----------------|--------|
|
||
350→| December 2025 | ~Dec 2025 | "December Bonus and Allocation for All Staff" | QR code → credential harvest |
|
||
351→| January 2026 | 2026-01-04 | "2026 Updated Pay Structure & Appraisal Guidelines" | QR code → credential harvest |
|
||
352→
|
||
353→**Attack Vector:**
|
||
354→1. Attacker spoofs internal sender (ghaubner, jlohr, etc.)
|
||
355→2. Sends directly to `dataforth-com.mail.protection.outlook.com` (bypasses MX/MailProtector)
|
||
356→3. M365 accepts despite SPF fail (no enforcement without transport rule)
|
||
357→4. Attachment contains QR code linking to `acuvatech.cyou?a=victim@dataforth.com`
|
||
358→5. QR code leads to credential harvesting page with pre-populated email
|
||
359→
|
||
360→**Origin IP:** 31.57.166.164 (no reverse DNS, external)

367→|----------|--------|-------|-------|
|
||
368→| Phishing Emails | Present | ✅ Removed | 10 emails deleted |
|
||
369→| "true" App | Present | ✅ Deleted | Removed from Entra |
|
||
370→| Direct M365 Bypass | ⚠️ Vulnerable | ✅ Blocked | Transport rule enforcing |
|
||
371→| OAuth Consents | ✅ Clean | ✅ Clean | No changes needed |
|
||
372→| MailProtector | Working | Working | Now enforced as only path |

|
||
376→### MailProtector Gateway IPs (Reference)
|
||
377→
|
||
378→These IPs are authorized to deliver mail to Dataforth M365:
|
||
379→```
|
||
380→52.0.31.31
|
||
381→52.0.74.211
|
||
382→52.0.70.91
|
||
383→```
|
||
384→
|
||
385→---
|
||
386→
|
||
387→### Verification Steps
|
||
388→
|
||
389→To verify transport rule is working:
|
||
390→1. **Exchange Admin Center** → **Mail flow** → **Message trace**
|
||
391→2. Search for sender: `attacker@malicious.com` (or any external)
|
||
392→3. Messages from non-MailProtector IPs should show **Failed/Rejected**
|
||
393→4. Rejection reason: "Transport rule: Mailptroctor Only (Reject Direct Mail)"
|
||
394→
|
||
395→---
|
||
396→
|
||
397→### Recommendations
|
||
398→
|
||
399→1. ✅ **COMPLETED:** Block direct M365 connections (transport rule)
|
||
400→2. ✅ **COMPLETED:** Remove phishing emails from all mailboxes
|
||
401→3. ✅ **COMPLETED:** Delete suspicious "true" app registration
|
||
402→4. **Consider:** External email warning banner for spoofed internal senders
|
||
403→5. **Consider:** User awareness training about QR code phishing
|
||
404→6. **Monitor:** Message trace for rejected bypass attempts
