   WHAT IS ROUTER ?/HOW IS IT WORK ?

A router is a device that connects two or more packet-switched networks or subnetworks. It serves two primary functions: managing traffic between these networks by forwarding data packets to their intended IP addresses, and allowing multiple devices to use the same Internet connection.

There are several types of routers, but most routers pass data between LANs (local area networks) and WANs (wide area networks). A LAN is a group of connected devices restricted to a specific geographic area. A LAN usually requires a single router.

A WAN, by contrast, is a large network spread out over a vast geographic area. Large organizations and companies that operate in multiple locations across the country, for instance, will need separate LANs for each location, which then connect to the other LANs to form a WAN. Because a WAN is distributed over a large area, it often necessitates multiple routers and switches*.

*A network switch forwards data packets between groups of devices in the same network, whereas a router forwards data between different networks.

How does a router work?

Think of a router as an air traffic controller and data packets as aircraft headed to different airports (or networks). Just as each plane has a unique destination and follows a unique route, each packet needs to be guided to its destination as efficiently as possible. In the same way that an air traffic controller ensures that planes reach their destinations without getting lost or suffering a major disruption along the way, a router helps direct data packets to their destination IP address.

In order to direct packets effectively, a router uses an internal routing table — a list of paths to various network destinations. The router reads a packet's header to determine where it is going, then consults the routing table to figure out the most efficient path to that destination. It then forwards the packet to the next network in the path.

What is the difference between a router and a modem?

Although some Internet service providers (ISPs) may combine a router and a modem within a single device, they are not the same. Each plays a different but equally important role in connecting networks to each other and to the Internet.

A router forms networks and manages the flow of data within and between those networks, while a modem connects those networks to the Internet. Modems forge a connection to the Internet by converting signals from an ISP into a digital signal that can be interpreted by any connected device. A single device may plug into a modem in order to connect to the Internet; alternately, a router can help distribute this signal to multiple devices within an established network, allowing all of them to connect to the Internet simultaneously.

Think of it like this: If Bob has a router, but no modem, he will be able to create a LAN and send data between the devices on that network. However, he will not be able to connect that network to the Internet. Alice, on the other hand, has a modem, but no router. She will be able to connect a single device to the Internet (for example, her work laptop), but cannot distribute that Internet connection to multiple devices (say, her laptop and her smartphone). Carol, meanwhile, has a router and a modem. Using both devices, she can form a LAN with her desktop computer, tablet, and smartphone and connect them all to the Internet at the same time.

What are the different types of routers?

In order to connect a LAN to the Internet, a router first needs to communicate with a modem. There are two primary ways to do this:

• Wireless router: A wireless router uses an Ethernet cable to connect to a modem. It distributes data by converting packets from binary code into radio signals, then wirelessly broadcasts them using antennae. Wireless routers do not establish LANs; instead, they create WLANs (wireless local area networks), which connect multiple devices using wireless communication.
• Wired router: Like a wireless router, a wired router also uses an Ethernet cable to connect to a modem. It then uses separate cables to connect to one or more devices within the network, create a LAN, and link the devices within that network to the Internet.

In addition to wireless and wired routers for small LANs, there are many specialized types of routers that serve specific functions:

• Core router: Unlike the routers used within a home or small business LAN, a core router is used by large corporations and businesses that transmit a high volume of data packets within their network. Core routers operate at the "core" of a network and do not communicate with external networks.
• Edge router: While a core router exclusively manages data traffic within a large-scale network, an edge router communicates with both core routers and external networks. Edge routers live at the "edge" of a network and use the BGP (Border Gateway Protocol) to send and receive data from other LANs and WANs.
• Virtual router: A virtual router is a software application that performs the same function as a standard hardware router. It may use the Virtual Router Redundancy Protocol (VRRP) to establish primary and backup virtual routers, should one fail.
  
  
  

What are some of the security challenges associated with routers?

Vulnerability exploits: All hardware-based routers come with automatically installed software known as firmware that helps the router perform its functions. Like any other piece of software, router firmware often contains vulnerabilities that cyber attackers can exploit (one example), and router vendors periodically issue updates to patch these vulnerabilities. For this reason, router firmware needs to be updated regularly. Unpatched routers can be compromised by attackers, enabling them to monitor traffic or use the router as part of a botnet.

DDoS attacks: Small and large organizations often are the targets of distributed denial-of-service (DDoS) attacks directed at their network infrastructure. Unmitigated network layer DDoS attacks can overwhelm routers or cause them to crash, resulting in network downtime. Cloudflare Magic Transit is one solution for protecting routers and networks from these kinds of DDoS attacks.

Administrative credentials: All routers come with a set of admin credentials for performing administrative functions. These credentials are set to default values, such as "admin" as the username and "admin" as the password. The username and password should be reset to something more secure as soon as possible: attackers are aware of the common default values for these credentials and can use them to gain control of the router remotely if they are not reset.

How to Hack Wi-Fi password in Android

If you want to enhance your knowledge and want to know the tricks and ways to hack the Wi-Fi password using Android device, then this article will help you. Lots of people are asking about how to hack Wi-Fi passwords using Android and whether it is possible or not. The straightforward answer is "yes" you can hack Wi-Fi passwords in Android devices using some tricks and tools (apps).

Before diving into our main topic about how to hack Wi-Fi passwords in Android phones, we first discuss some of the basic information about the type of Wi-Fi password security.

Types of Wi-Fi Password Security

There are primarily three different types of Wi-Fi password securities. These Wi-Fi securities are as follows:

1. Wired Equivalent Privacy (WEP).
2. Wi-Fi Protected Access (WPA).
3. Wi-Fi Protected Setup (WPS).

Wired Equivalent Privacy (WEP)

Wired Equivalent Privacy (WEP)

Wi-Fi security is one of the most popular and widely used Wi-Fi securities in the entire world. However, this security is a most week and insecure as well. Someone can easily crack and hack such Wi-Fi security using Airmon tools from Kali Linux and Aircrack.

Method 1: Hacking Wi-Fi password in Android using AndroDumper App APK (without Rooting)

AndroDumper is another popular app used for hacking Wi-Fi passwords in Android phones. This app is operated over a non-rooted device to hack Wi-Fi passwords. Follow the below mention steps to hack Wi-Fi passwords on Android using this app.

1. Download and install the AndroDumper app on your Android phone.
2. Turn on the Wi-Fi settings on your Android device.
3. Launch the AndroDumper app and click on the refresh button present at the top of the screen to search and get nearby Wi-Fi networks.
4. Choose the network you wish to hack and connect and tap on it.
5. Now the app will try to connect with your chosen network with every possible combination of alphabets and number passwords. If the selected network has a weak Wi-Fi password, then this app possibly hacks it.

Method 2: Hacking Wi-Fi password in Android having WPA2 WPS Router (Root device)

In this method of hacking Wi-Fi passwords in Android, we will use the Bcmon and Reaver Android app. At first, you need a root Android phone if you don't have tried to root your device. Ensure that your root Android phone contains Broadcom bcm4329 or bcm4330 chipsets as present in Samsung Galaxy S1/S2, HTC Desire HD, Nexus 7, Nexus 1, etc.

1. Download and install the BCmon app APK file on your Android phone. This app helps you to monitor your Broadcom chipset and cracking PIN.
2. Now, download and install the Reaver Android app that figure out and cracking the WPS Wi-Fi network password.
3. After the app installation, launch the BCmon app and tap on the "monitor mode" option.
4. Again launch the Reaver app and confirm on the screen that you are not using it for any illegal activity. Tap on the APN or access point you want to crack and continue Wi-Fi password. Sometimes you need to verify your monitor mode to continue, and you can do this by reopening the BCmon app again.
5. Go to settings in the Reaver app and checked to mark "Automatic Advanced setting" box.
6. Finally, start your Wi-Fi cracking process by clicking on the start attack; in this last step, cracking the WPS Wi-Fi security may take 2-10 hours to succeed.

Method 3: Hacking Wi-Fi password in Android using Wi-Fi WPS Connect app (Root device)

Using the Wi-Fi WPS Connect app you can hack Wi-Fi password on Android. The app works on both rooted and non-rooted (Lollipop and above) phones. However, it is mainly preferred for the rooted device because of the database information.

If you found any Wi-Fi connection on your Android device having WPS security, you can easily connect with it without providing any password. The WPS Connect app bypasses WPS Wi-Fi security and connects with Wi-Fi without entering any password.

Below are the steps to hack Wi-Fi password and connect your Android phone using this app:

1. Download and install the Wi-Fi WPS Connect app on your Android phone.
2. Enable the Wi-Fi settings of your phone.
3. Launch the WPS Connect app and tap on the scan button to scan all nearby Wi-Fi networks.
4. It takes few times to display all nearby Wi-Fi networks, including their details (such as password security types, network types, signal strength, etc.).
5. Choose a Wi-Fi network and tap on it you wish to hack. A pop-up screen appears with a pre-defined list of keys (PIN).
6. Tap on the key to start your hacking process.
7. The app tries several times to hack Wi-Fi with default keys and the most widely used Wi-Fi keys.
8. Wait for few minutes, and the Wi-Fi password will be hacked successfully.

Method 4: Hacking Wi-Fi password in Android using WPSAPP

WPSAPP is an all-in-one app that allows you to connect nearby Wi-Fi networks using an 8-digit PIN. The WPSAPP app makes easier and convenient to hack Wi-Fi password in both rooted and non-rooted Android phones. It applies several algorithms for generating random pins as well as some default pins. Using this app, you can hack any WEP Wi-Fi network without any difficulties.

When you scan for the networks, they appear with the red cross, question marks, and green tick marks. The red cross networks are secure, and their password is unknown. The networks showing with question marks have WPS protocol enabled, their pin is unknown, and the app allows testing them with a most common pin. Finally, the green ticks networks are WPS protocol enabled and their password known, and they can be connected.

1. Download and install the WPSAPP app on your Android phone.
2. Now, open the app and search for the nearby Wi-Fi networks for you.
3. Click on the enabled WEP network you want to connect.
4. Click on the "CONNECT WITH PIN" button, and after few seconds, the app displays your network password.
