A fake login, invoice, fax, voicemail, document, or reply can look normal because it borrows a real name and a familiar workflow. Staff need a fast way to inspect the request, verify it outside the message, and report what happened without shame or delay.
Education and planned-review guidance only. A public web form is not an incident channel. If an account, device, payment, patient message, or ePHI may be involved now, use the practice's approved response process and qualified technical, legal, insurer, privacy, and regulatory resources. Do not send the suspicious email, PHI, credentials, logs, screenshots, headers, links, attachments, or evidence through this page.
The goal is a repeatable decision, not a staff guessing contest.
What action is the message trying to trigger: sign in, pay, open, share, approve, or change a normal workflow?
Do the real sender, reply-to address, link destination, timing, and language match the expected person and domain?
Can the request be verified through a known phone number, portal, or fresh message that does not use the suspicious thread?
If someone already interacted, which account, session, device, mailbox, connected app, or business process may be exposed?
Who receives the report, who performs containment, and who makes privacy, legal, insurer, or breach-notification decisions?
Messages can use correct spelling, real logos, known names, copied conversation history, plausible clinical or billing context, and legitimate cloud services. A familiar display name is not identity proof, and a successful MFA prompt is not always proof that the sign-in is safe.
Teach staff to identify the requested action, inspect the real route, verify through a separate known channel, and report early. Build technical controls around that human decision so one mistake does not automatically become a long-lived account session or a practice-wide problem.
This sanitized specimen is a training model, not a live inbox, threat detector, or real patient conversation. Use it to teach what staff should inspect before acting.
We need the office manager to review the updated account document before access closes. Use the secure review button below and approve the sign-in prompt.

Staff rule: do not “test” a suspicious link, QR code, attachment, reply address, or phone number. Report the message through the approved path and verify the business request separately.
A mailbox can contain live conversations, password resets, calendars, shared files, vendor threads, billing instructions, contact lists, and access to connected applications. Scope the account by what it can reach, not just by how many messages it holds.
Microsoft's current guidance for a compromised Microsoft 365 account includes reviewing suspicious activity, forwarding, delegated access, sign-in methods, active sessions, and related controls. The exact response depends on the tenant, licenses, evidence, and authorized scope.
Keep the staff instruction short. Let the authorized response team handle technical evidence, privacy analysis, and escalation.
No single control catches every message. The useful question is what happens when one layer misses.
Move toward phishing-resistant MFA where the platform, licenses, devices, and workflow support it. Protect administrators and recovery paths carefully.
Evidence: authentication methods, enforcement scope, exceptions, recovery ownersReview external forwarding, delegated access, shared mailbox ownership, impersonation protection, suspicious-message reporting, and legacy authentication.
Evidence: current policy, exceptions, alert ownership, review recordRequire a known separate channel for payment changes, payroll, bank details, credential recovery, unusual file shares, and vendor access requests.
Evidence: owner, secondary channel, approval trail, exception handlingKeep browsers, office apps, operating systems, and endpoint protection current. Restrict risky execution and downloads according to the environment.
Evidence: managed scope, patch posture, protection status, isolation routeTrain with the messages staff actually see: fax, voicemail, payer, referral, portal, e-signature, invoice, shared file, and internal reply.
Evidence: reporting path, drill findings, recurring confusion, follow-up ownerName who can contain an account, inspect a device, preserve evidence, call vendors, and coordinate privacy, legal, insurer, and leadership decisions.
Evidence: contacts, authority, escalation route, bounded response recordOCR reported that the phishing attack affected 189,763 individuals' unsecured ePHI and announced a $600,000 settlement. The case is evidence of consequence, not a prediction for another practice.

Stop interaction, use the approved route, describe what happened, retain the message in place unless directed otherwise, and identify the business workflow affected.
Review sessions, credentials, sign-in methods, rules, forwarding, delegated access, connected applications, devices, and technical scope within authorization.
Decide workflow continuity, communications, vendor coordination, documented facts, internal authority, and which qualified resources need involvement.
Interpret contracts and policy, advise on evidence and privilege, determine notification or reporting duties, and address regulatory or law-enforcement questions.
Use the practice's existing IT provider, email administrator, cyber insurer, or approved incident-response provider. HealthDesk does not provide emergency incident response.
Use the cybersecurity owner for preventive safeguards across email, identity, endpoints, remote access, and monitoring.
Healthcare cybersecurityUse the tenant owner for sign-in methods, roles, mailboxes, forwarding, groups, sharing, devices, and controlled changes.
Microsoft 365 managementUse the compliance owner for documented risk-analysis support and safeguard/evidence questions, not legal certification.
HIPAA compliance supportUse the managed IT owner for ongoing account lifecycle, support, patching, documentation, and vendor coordination.
Managed IT servicesUse the recovery owner for protected-scope review, restore evidence, dependencies, and a bounded continuity rehearsal.
Backup & recoveryIt can create a privacy or security concern when ePHI may be accessed, used, disclosed, altered, or made unavailable. Qualified owners must review the facts and make formal determinations; a password reset alone does not answer the question.
No. MFA adds protection, but methods differ and some prompts or codes can be phished or abused. Current Microsoft and CISA guidance encourages phishing-resistant methods where practical.
Use the practice's approved reporting process. If interaction or compromise may have happened, do not destroy, alter, forward, or investigate evidence on your own; follow authorized responder instructions.
Use a known phone number, portal, bookmark, contract contact, or fresh conversation already controlled by the practice. Do not use the phone number, reply path, QR code, or link supplied by the questionable message.
Stop interacting and report immediately. Describe whether the person clicked, opened, downloaded, replied, entered credentials, approved MFA, changed payment details, or saw an unexpected device prompt.
Do not send PHI, patient details, the suspicious message, sender or recipient data, headers, links, QR codes, attachments, screenshots, credentials, logs, evidence, contracts, or confidential system information.
