Router Password Change: Can Hackers See It?

TL;DR

Yes, a hacker could see you changing your router password if they’re already actively monitoring your network. However, there are steps you can take to minimise the risk and make it much harder for them.

How a Hacker Might See Your Password Change

Here’s how someone could potentially view your router password change:

• Man-in-the-Middle (MitM) Attack: If your network is compromised, a hacker can intercept the traffic between your device and the router. This means they see everything you send, including your new password.
• Router Vulnerabilities: Older or unpatched routers have security holes that hackers exploit to gain access. Once inside, they can monitor all activity.
• Network Sniffing: Using tools like Wireshark (advanced), a hacker on the same network could capture and analyse packets of data.

Steps to Secure Your Router Password Change

1. Use HTTPS: Always access your router’s settings via https://, not http://. The ‘s’ means the connection is encrypted. Most modern routers default to this, but double-check.
2. Strong Password: Create a strong, unique password for your router. This should be at least 12 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid personal information like birthdays or names.
3. Update Router Firmware: Regularly update your router’s firmware (software). Manufacturers release updates to fix security vulnerabilities. Check your router’s admin interface for updates.

   (Example - TP-Link Interface) System Tools > Firmware Upgrade

4. Change Default Credentials: If you haven’t already, change the default username and password immediately. These are well known to hackers.
5. Use a VPN (Virtual Private Network): A VPN encrypts all your internet traffic, making it much harder for anyone to intercept your data, including your router password.
   • Install a reputable VPN client on each device you use.
   • Connect to the VPN before changing your router password.
6. Use Wired Connection: If possible, change your password using a wired Ethernet connection instead of Wi-Fi. This reduces the risk of interception.
7. Check Router Logs: Regularly review your router’s logs for any suspicious activity. Look for unknown IP addresses or unusual login attempts.

   (Example - ASUS Interface) Administration > System Log

8. Enable WPA3 Encryption: If your router and devices support it, use WPA3 encryption for your Wi-Fi network. It’s more secure than older standards like WPA2.

   (Example - Netgear Interface) Wireless > Security > Security Mode = WPA3 Personal

9. Disable Remote Access (If Not Needed): If you don’t need to access your router settings remotely, disable remote administration. This closes a potential entry point for hackers.

   (Example - D-Link Interface) Setup > Administration > Remote Management = Disabled

10. Consider Two-Factor Authentication (2FA): Some routers offer 2FA, adding an extra layer of security. This requires a code from your phone or email in addition to your password.

What if you suspect your router is compromised?

• Factory Reset: As a last resort, perform a factory reset on your router. This will erase all your settings, so back them up first if possible (but be aware that backups may also contain malicious configurations).
• Contact Your ISP: Contact your internet service provider for assistance.
