Printers on the network are still computers
Default passwords, ancient firmware, and flat VLANs turn MFPs into quiet pivot points.
Multifunction printers scan to email, store documents, and speak SMB. Treat them like endpoints.
Quick wins
- Change default admin passwords
- Put printers on a restricted VLAN
- Disable unused protocols
- Keep firmware reasonably current
Scan-to-email
Prefer authenticated SMTP to Microsoft 365 over a wide-open relay. Open relays become spam engines, and sometimes worse.
