Hi SOC, I think I just got phished. Around 10:20 this morning I scanned a printed QR poster taped near the visitor parking sign-in counter. The poster said "Free Visitor Parking Validation — Scan QR to Validate" and looked official. The QR opened a short link in my work iPhone browser, which redirected to a Microsoft 365 sign-in page at m365-validate-acme[.]xyz. I entered my work email and password. The page returned a "thanks" screen and bounced me to office.com. There was no challenge (I think my phone had a cached M365 session). I noticed the wrong domain about 15 minutes later when I looked back at my browser history. The poster is still on the lobby wall as of 10:42. Please advise. I have not changed my password yet — wanted to ask first. — Daniel (Finance)

Hi Daniel,

Thank you for reporting this quickly. Based on what you described, we are treating this as a confirmed QR-code phishing incident involving your Microsoft 365 credentials.

Please do not revisit the link, do not enter any additional information, and do not clear your browser history. We are preserving the details as evidence.

We are taking the following actions immediately:

We will force a password reset for your Microsoft 365 account.
We will revoke active Microsoft 365 sessions and refresh tokens.
We will review your recent sign-in activity for any suspicious access attempts.
We will check your mailbox for any unusual forwarding rules, inbox rules, sent messages, or unauthorized activity.
We will coordinate with reception/security to remove and preserve the QR poster as evidence.
We will search for any other users or devices that may have visited the same phishing link.

Please keep your work iPhone available and connected so we can verify device compliance and confirm whether any additional action is needed.

At this time, do not reuse your old password anywhere else. If you used that same password on any other system, please let us know immediately.

We will follow up once the account review is complete.

Thank you again for reporting this quickly.

    Reset password AND revoke sessions AND block the phishing domain at proxy AND remove the poster (after photographing) — all four steps are needed.

  • Attack understanding0% coverage

    Name this as quishing / QR phishing and explain that the lure lives outside email — email URL filters never see it; the credential was harvested via a fake M365 page.

Situation & summary

Daniel (Finance) scanned an unauthorized 'Free Parking Validation' QR poster in the office lobby at 10:21, was redirected through a shortener to a Microsoft 365 look-alike at m365-validate-acme[.]xyz, and entered his work credentials. The phishing domain is 6 days old, hosted on a low-reputation provider. An attacker sign-in attempt from 23.94.184.55 at 10:43 was blocked by Conditional Access (non-compliant device), but the credential is still in attacker hands. The poster was hung the previous evening by an unidentified person on CCTV.

Severity & priority

Rated SEV-3 / P3. Treat as a P1 credential compromise on a Finance account even though the attacker sign-in attempt was blocked at CA — the credential is already leaked and attempts will continue.

Prioritization & impact
  • Treat as a P1 credential compromise on a Finance account even though the attacker sign-in attempt was blocked at CA — the credential is already leaked and attempts will continue.
  • Containment-first: reset password, revoke sessions, block the phishing domain at the proxy.
  • Loop in Identity / M365 admin, Finance management, and Facilities / Reception (the poster is still on the wall).
Containment (actions taken / in progress)
  • Reset Daniel's password and force sign-out everywhere so the cached M365 session on the iPhone (and any other device) is invalidated.
  • Block `m365-validate-acme[.]xyz` and the `lnk.short-url[.]co/p9k2x` shortener at the corporate proxy / DNS resolver; add the phishing domain to threat intel feeds.
  • Photograph the poster in situ, then have Facilities remove it; do not let anyone else dispose of it without the photo.
Investigation (in progress)
  • Pull the corporate mobile proxy log for the last 24 hours and search for any other employee who hit `lnk.short-url[.]co/p9k2x` or `m365-validate-acme[.]xyz`.
  • Audit Entra ID sign-in tenant-wide for the attacker IP `23.94.184.55` or the same UA in the last 24 hours.
  • Check Daniel's mailbox for any new inbox rules, OAuth grants, or forwarding added in the last 30 minutes.
  • Review building CCTV for the previous evening (18:30–19:00) to identify the person who taped up the poster, and check other entrances for similar posters.
Recovery & next steps
  • Re-enable Daniel's account after password reset and session revocation; require an interactive MFA on next sign-in.
  • Post a building-wide notice that only Facilities / Reception may put up lobby signage, and brief reception on the poster-removal authority.
  • Run a targeted user-awareness reminder specifically on QR / quishing lures — the email-phishing training does not cover physical lures.
Evidence preservation
  • Photograph the poster in full and close-up of the QR before removing it; keep the original poster as physical evidence in the SOC evidence locker.
  • Export the corporate mobile proxy log entries for Daniel's device and the wider tenant search.
  • Export the Entra ID sign-in log row for the 10:43 attempt, including the CA-block reason.
  • Pull the CCTV clip showing the poster being hung and the morning shift first noticing it.
Stakeholder communication
  • Brief Daniel on what was done and what he should not do (do not enter credentials into any prompt that follows up; do not delete his browser history).
  • Notify the Finance lead, Identity / M365 admin, and the on-call SOC lead.
  • Notify Facilities and Reception so they remove the poster and brief lobby staff on unauthorized signage.
Do NOT
  • Do not throw away or remove the poster before photographing and preserving it as evidence.
  • Do not just tell Daniel `be careful next time` — the credential is already leaked.
  • Do not wipe Daniel's iPhone; no malware has been observed and the credential capture was server-side.
  • Do not share the new password over chat or email — re-deliver via a secure channel.
  • Do not propose `blocking QR codes` generically — block the destination domain at the proxy / DNS.

Dangerous actions to avoid

  • Do not throw away or remove the poster before photographing and preserving it as evidence.
  • Do not just tell Daniel `be careful next time` — the credential is already leaked.
  • Do not wipe Daniel's iPhone; no malware has been observed and the credential capture was server-side.
  • Do not share the new password over chat or email — re-deliver via a secure channel.
  • Do not propose `blocking QR codes` generically — block the destination domain at the proxy / DNS.

How to improve next time

  • Email URL filters do not catch out-of-band lures — posters, stickers, name tags, paper invoices are all outside their visibility.
  • Physical evidence (the poster itself) is part of the investigation chain — photograph in situ, then preserve, then remove.
  • BYOD devices touching M365 are inside the even if not enrolled in — credential capture happens server-side.
  • A blocked sign-in attempt is still a credential leak — the attacker will try other vectors with the same password.
  • Quishing training is a distinct user-awareness module from email phishing training; the failure mode (trust of physical signage) is different.

Why did I get this score?

Your verdict was Fail at 34/100. That total is the sum of deterministic rubric points across 8 categories — each scores how much of its expected, ordered steps your answer covered, not an opinion about your writing. Your strongest coverage was Clarity & structure (100%). Points were held back mostly in Containment (0%), Attack understanding (0%), Recovery (33%).
