Step-by-Step Guide to Protecting Your MikroTik Router from Hackers

-

 If your MikroTik router has been hacked, it’s crucial to act quickly to secure your network and prevent further damage. Here’s a detailed, step-by-step guide on what you should do:

1. Disconnect the Router from the Internet

    • Physical Disconnection: Unplug the Ethernet cable connected to the WAN port of your router.
    • Purpose: Prevent the hacker from maintaining control or causing further damage.

2. Reset the Router to Factory Settings

    • Find the Reset Button: Usually located at the back or bottom of the router.
    • Press and Hold: Use a paperclip or a similar object to press and hold the reset button for about 10-30 seconds (check your router’s manual for exact time).
    • Note: This will erase all current configurations and settings.

3. Update Router Firmware

    • Access the Router: After resetting, reconnect the router to your computer via an Ethernet cable.
    • Log In: Open a web browser and navigate to the default IP address of the router (commonly 192.168.88.1 for MikroTik). The default username is usually admin and the password field is blank (if not, refer to the router manual).
    • Download Firmware: Go to the MikroTik website, find your router model, and download the latest firmware version.
    • Upload Firmware: Go to the router’s web interface, navigate to the firmware update section, and upload the firmware file. Follow the prompts to complete the update.

4. Change Default Credentials

    • Access Router Settings: Log in to the router’s web interface with the default credentials.
    • Change Username and Password: Immediately change the default username and set a strong password (use a mix of upper and lower case letters, numbers, and symbols).

5. Configure Basic Security Settings

      • Disable Unused Services: Turn off services you don’t need (e.g., FTP, Telnet).
      • Navigate to IP > Services and disable unnecessary services.
  • Enable HTTPS: Secure the web interface.
      • Navigate to IP > Services > www-ssl.
  • Set Up a Firewall:
      • Navigate to IP > Firewall.
      • Create rules to block unauthorized access.
      • Example rules:



6. Reconfigure Network Settings

      • Set Up Wi-Fi: Reconfigure your SSID and set a strong Wi-Fi password using WPA3 encryption (if supported).
      • Navigate to Wireless > Security Profiles.
      • Set WPA3 as the security mode.
  • Reconfigure LAN Settings:
      •  Reconfigure DHCP, static IPs, and any port forwarding rules as needed.

7. Monitor and Maintain

      • Enable Logging: Set up logging to monitor for any unusual activity.
      • Navigate to System > Logging and configure appropriate logging actions.
      • Regular Updates: Check for firmware updates regularly and apply them promptly.
      • Backup Configuration: Periodically back up your router configuration.
      • Navigate to Files > Backup.

8. Additional Security Measures

      • Use VPN: For remote access, set up a VPN instead of opening ports to the internet.
      • Navigate to PPP > Interface > L2TP Server.
      • Configure VPN settings as needed.
    • Enable Intrusion Detection: If available, enable any intrusion detection features.
    • Network Segmentation: Separate critical devices from less secure ones using VLANs.

9. Educate Users

  • Inform Family/Employees: Educate users on safe internet practices to avoid phishing attacks and malware.

By following these steps, you can significantly improve the security of your MikroTik router and reduce the risk of future compromises.

  ARP Spoofing and MITM Attacks with Bettercap In the world of cybersecurity, one of the most common attack techniques used by hackers is the Man-in-the-Middle (MITM) attack, often combined with ARP (Address Resolution Protocol) spoofing. This article will explain the concepts of ARP spoofing, MITM attacks, why attackers use these methods, and how to use the Bettercap tool to perform these attacks effectively. I have made a youtube Video - Network hacking for this penetration attack. This is only for education purpose so please don't use this for any harmful activities. The author will not be liable for any bad activities.  What is ARP Spoofing? ARP spoofing, also known as ARP poisoning, is a method of attacking a local area network (LAN) by sending fake ARP messages to associate an attacker’s MAC address with the IP address of another device (such as a router or another user’s machine). This trick allows the attacker to intercept or alter traffic between devices on the...
