Yes — we respond to hacked Microsoft 365 accounts and business email compromise for Kingwood, TX businesses, and the first hour is about evidence, not password resets. If a client says they paid an invoice you never sent, or you're seeing sign-ins from places nobody travels, the attacker has likely been reading your mail quietly for weeks.
| Symptom | Likely cause | Safe first step | When to call |
|---|---|---|---|
| A client paid an invoice to bank details that aren't yours | Active business email compromise with thread hijacking | Preserve the email thread; verify by phone, not by reply | Immediately — money is actively moving |
| MFA prompts you didn't request | Attacker holds a valid password and is pushing for approval | Deny every prompt; do not approve one to make it stop | Same day, before the attacker gets a tired approval |
| Inbox rule nobody created, or mail vanishing | Attacker hiding replies to keep the fraud invisible | Screenshot the rule — do not delete it yet | Before making any changes to the mailbox |
| Sign-ins from unfamiliar locations in the 365 logs | Credential compromise, possibly weeks old | Export the sign-in log from a clean admin device | Before a mass password reset destroys the trail |
Yes. We take business email compromise cases for Kingwood firms — revoking the attacker's sessions, auditing what they had access to, closing the entry point, and producing documentation your insurer and clients will accept. Response starts by phone the same day.
The businesses along Kingwood Drive and through the professional parks are mostly the exact shape attackers prefer: ten to forty people, real money moving through email, and one person who is simultaneously the owner, the global admin and the main mailbox. That last part is the structural problem. When the global administrator account is also the account that opens attachments all day, a single successful phish hands over the entire tenant — and there is no second admin to notice.
It rarely looks like a hack. The attacker's goal is to stay quiet and read, so the visible symptoms are mundane and easy to explain away for weeks.
Preserve first, then evict, then close. We pull and preserve the sign-in and audit logs before making changes, revoke active sessions and refresh tokens (a password reset alone does not log an attacker out), remove malicious inbox and forwarding rules, review OAuth app consents and app passwords, then re-enrol MFA and separate the admin role from daily-use accounts. Only then do we look at hardening, because hardening a tenant the attacker is still inside accomplishes nothing.
Most Kingwood firms discover their cyber policy requires a written incident timeline they cannot produce themselves. We provide one: what was accessed, when, from where, which mailboxes and data were in scope, and what was done in response — in language your carrier, your attorney and your affected clients can all read.
