A 16-year-old got into Microsoft data with the username "admin": how to find the default passwords in your Mexico operation today

On October 11, 2026, Xataka México reported that a 16-year-old reached Microsoft data, what the outlet counts as 17.3 billones of rows. No movie-style hack. Just the username “admin”.

If that can happen at Microsoft, think about the camera recorder at your Mexico warehouse. The one a local installer set up two years ago and nobody at headquarters has ever logged into.

What a default password is and why it still works

A default password is the one a device ships with: admin and admin, admin and 12345, or nothing at all. It is in the manual. The manual is online.

The issue is rarely technical. It is about hurry. The installer gets everything running, leaves, and nobody opens the admin panel again.

For foreign companies it gets worse. Your global IT team manages laptops and Microsoft 365, but the router, cameras and phone system in Querétaro or Monterrey were bought and installed locally. They live outside your standards.

Meanwhile, bots scan the internet all day trying exactly those combinations. They are not looking for you. They are looking for anyone who skipped the change.

Where default passwords hide at a Mexico site

In our experience, we rarely review a Mexico office or plant without finding at least one device still on its factory login.

Device	Where it sits	Why it gets forgotten
DVR/NVR and IP cameras	Warehouse, front desk, server room	A local contractor installed it
ISP router or modem	Next to the rack	“It belongs to the internet provider”
Multifunction printer	Front desk or accounting	Nobody knows it has a web panel
NAS	Under the IT desk	Set up once, never revisited
IP phone system	Telecom closet	Left by the telephony vendor
Hosting, ERP and databases	Cloud or local server	The implementation admin account was never removed

A NAS is a network drive where many sites keep their backups. An IP phone system handles the extensions. Someone inside either one can wipe your backups or run up long-distance calls on your bill.

We have seen the same pattern with exposed IP cameras and the MikroTik router takeover flaw. Different box, same door.

A 1-hour checklist your local team can run today

1. Inventory, 15 minutes. List everything with an IP address: cameras, printers, router, NAS, phone system. Add web panels: hosting, ERP, databases. The local installer invoice is a good starting point.
2. Test and change passwords, 20 minutes. Log in to each panel. If admin and admin works, change it right there. One long, unique password per device. Rename the admin user where possible.
3. Two-factor authentication, 10 minutes. 2FA adds a second step, like a code on a phone. Turn it on for hosting, email and ERP.
4. Password manager, 10 minutes. Store every credential in the same corporate manager HQ already uses, shared only with the right people. No notebooks at the front desk.
5. Take admin panels off the internet, 5 minutes. Router, DVR and NAS panels should not open from outside. Remote access goes through a VPN, an encrypted tunnel into your network.

What to avoid

Do not reuse one new password across every device. If one falls, they all fall.

Do not send it over WhatsApp to the site group chat.

And do not let the local installer be the only person who knows it. Our favorite test: if your Mexico vendor disappeared tomorrow, could someone in your company log in to every device? If not, that is your risk.

Let’s talk

What about your Mexico operation?

At ProcessBi, a credentials and device audit is part of our IT support plans. We inventory everything with an IP, replace factory passwords, enable 2FA and hand the credentials over to your corporate password manager, with reports in English.

When we install Hikvision CCTV or networks, no device leaves with its out-of-the-box password.
