guidance based on HPE HPESBNW05162 and Group-IB k0t recommendations (Oct 21-22)

2026-10-23

### Tip: get firewall, VPN and wireless-controller management interfaces off the internet, and rotate the LDAP bind accounts stored on them

- **Inventory:** search Shodan, Censys or your own attack-surface tool for your FortiGate, FortiWeb, GlobalProtect and Aruba management pages. Attackers like k0t build target lists the same way.
- **Restrict:** put admin GUIs and CLIs on a management VLAN or allow them only from admin jump hosts, as HPE recommends for the new AOS flaws.
- **Harden logins:** remove default and shared admin passwords, require MFA on VPN portals, and lengthen lockouts. Investigate lockout bursts instead of just clearing them.
- **Assume configs leak:** appliance configs often hold LDAP/AD bind passwords that can be decrypted. Use a low-privilege bind account, rotate it, and alert when it logs in anywhere but the appliance.
