Hack ADSL Router Using NMAP- picateshackz.com

Asynchronous digital subscriber line (DSL or ADSL) modem is a device used to connect a computer or router to a telephone line which provides the digital subscriber line service for connectivity to the Internet, which is often called DSL or ADSL broadband. In this guide I will show you show you how to scan IP range for connected ADSL or DSL modem routers and find DSL ADSL router hack remotely. This guide applies to Windows, Linux or Mac, so it doesn’t matter what’s your Operating system is, you can try the same steps from all these operating systems. The term DSL or ADSL modem is technically used to describe a modem which connects to a single computer, through a USB port or is installed in a computer PCI slot. The more common DSL or ADSL router which combines the function of a DSL or ADSL modem and a home router, is a standalone device which can be connected to multiple computers through multiple Ethernet ports or an integral wireless access point. Also called a residential gateway, a DSL or ADSL router usually manages the connection and sharing of the DSL or ADSL service in a home or small office network.
Put this together with Wireshark hacking for http websites, you got a nightmare for the user behind that router as all their passwords and details can be tracked very easily.

What’s in a DSL ADSL Router?

A DSL or ADSL router consists of a box which has an RJ11 jack to connect to a standard subscriber telephone line. It has several RJ45 jacks for Ethernet cables to connect it to computers or printers, creating a local network. It usually also has a USB jack which can be used to connect to computers via a USB cable, to allow connection to computers without an Ethernet port. A wireless DSL or ADSL router also has antennas to allow it to act as a wireless access point, so computers can connect to it forming a wireless network. Power is usually supplied by a cord from a wall wart transformer. It usually has a series of LED status lights which show the status of parts of the DSL or ADSL communications link:
  1. Power light – indicates that the modem is turned on and has power.
  2. Ethernet lights – There is usually a light over each Ethernet jack. A steady (or sometimes flashing) light indicates that the Ethernet link to that computer or device is functioning
  3. DSL or ADSL light – a steady light indicates that the modem has established contact with the equipment in the local telephone exchange (DSL or ADSLAM) so the DSL or ADSL link over the telephone line is functioning
  4. Internet light – a steady light indicates that the IP address and DHCP protocol are initialized and working, so the system is connected to the Internet
  5. Wireless light – only in wireless DSL or ADSL modems, this indicates that the wireless network is initialized and working
Almost every ADSL DSL modem router provides a management web-page available via Internal network (LAN or Local area network) for device management, configuration and status reporting. You are supposed to login to the management web-page, configure a username password combination provided by your ISP (Internet service provider) which then allows you to connect to internet. The network is divided into two parts:

External Network

External network indicates the part where ADSL DSL modem routers connects to upstream provider for internet connectivity. Once connected to the ISP via a Phone line (ADSL DSL Modem routers can use conventional Copper Phone lines to connect to ISP at a much higher speed), the router gets an IP address. This is usually a Publicly routable IP address which is open to the whole world.

Internal Network

Internal network indicates the part where devices in Local Area Network connects to the ADSL DSL modem router via either Wireless or Ethernet cable. Most modem DSL ADSL Modem routers runs a DHCP server internally which assigns an Internall IP address to the connected device. When I say device, this can be anything from a conventional computer, a laptop, a phone (Android, Apple, Nokia or Blackberry etc.), A smart TV, A Car, NAS, SAN, An orange, A banana, A cow, A dragon, Harry Potter … I mean anything that’s able to connect to internet! So you get the idea. Each device get’s it’s own IP address, a Gateway IP and DNS entries. Depending on different DSL ADSL Modem router, this can be slightly different, but the idea remains the same, the DSL ADSL Router allows users to share internet connectivity. These DSL ADSL Modem Routers are like miniature Gateway devices that can have many services running on them. Usually they all use BusyBox or similar proprietary Linux applications on them. You want to know what a DSL ADSL Router can do? Here’s a list of common services that can run on a DSL ADSL Modem Router:
  1. ADSL2 and/or ADSL2+ support
  2. Antenna/ae (wireless)
  3. Bridge/Half-bridge mode
  4. Cookie blocking
  5. DHCP server
  6. DDNS support
  7. DoS protection
  8. Switching
  9. Intrusion detection
  10. LAN port rate limiting
  11. Inbuilt firewall
  12. Inbuilt or Free micro-filter
  13. Java/ActiveX applet blocking
  14. Javascript blocking
  15. MAC address filtering
  16. Multiple public IP address binding
  17. NAT
  18. Packet filter
  19. Port forwarding/port range forwarding
  20. POP mail checking
  21. QoS (especially useful for VoIP applications)
  22. RIP-1/RIP-2
  23. SNTP facility
  24. SPI firewall
  25. Static routing
  26. So-called “DMZ” facility
  27. RFC1483 (bridged/routed)
  28. IPoA
  29. PPPoE
  30. PPPoA
  31. Embedded PPPoX login clients
  32. Parental controls
  33. Print server inbuilt
  34. Scheduling by time/day of week
  35. USB print server
  36. URL blocking facility
  37. UPnP facility
  38. VPN pass-through
  39. Embedded VPN servers
  40. WEP 64/128/256 bit (wireless security)
  41. WPA (wireless security)
  42. WPA-PSK (wireless security)
That’s a lot of services running on a small device that are configured by nanny, granny, uncle, aunt and the next door neighbour, in short many non technical people around the world. How many of those configured badly? Left ports open left right and center? Didn’t change default admin passwords? Many! I mean MANY! In this guide we will use namp to scan a range of IP addresses, from output we will determine which are DSL ADSL Routers and have left their Management ports open to External Network. (again read top section to know which one is a external network). A typical ADSL Router’s Management interface is available via following URL:
http://10.0.0.1/
http://192.168.0.1/
http://192.168.1.1/
http://192.168.1.254/
etc.
This is the Management page for DSL ADSL modem router and it’s always protected by a password. By default, this password is written below a DSL ADSL modem router in a sticker and they are one of these combinations: Username/Password
admin/admin
admin/password
admin/pass
admin/secret
etc.
A lot of the home users doesn’t change this password. Well, that’s ok. It doesn’t hurt much cause this is only available via a connected device. But what’s not OKAY is when users open up their management to the external network. All you need to know what’s the Public IP address for your target and just try to access this management page externally.

Installing NMAP

I use Kali Linux which comes with NMAP Preinstalled. If you are using Windows or Mac (or any other flavour of Linux) go to the following website to download and install NMAP.

Linux Installation:

For Ubuntu, Debian or aptitude based system NMAP is usually made available via default repository. Install NMAP using the following command:
