HOW TO HACK WIFI linux/Android


Wireless network basics

  • Wireless local-area networks are based on IEEE 802.11. This is a set of standards defined by the Institute of Electrical and Electronics Engineers.
  • 802.11 networks are either infrastructure networks or ad hoc networks. By default, people refer to infrastructure networks. Infrastructure networks are composed of one or more access points that coordinate the wireless traffic between the nodes and often connect the nodes to a wired network, acting as a bridge or a router.

    Each access point constitutes a network that is named a basic service set or BSS. A BSS is identified by a BSSID, usually the MAC address of the access point.

    • Each access point is part of an extended service set or ESS, which is identified by an ESSID or SSID in short, usually a character string.
    • A basic service set consists of one access point and several wireless clients. An extended service set is a configuration with multiple access points and roaming capabilities for the clients. An independent basic service set or IBSS is the ad hoc configuration. This configuration allows wireless clients to connect to each other directly, without an access point as a central manager.
    • Access points broadcast a signal regularly to make the network known to clients. They relay traffic from one wireless client to another. Access points may determine which clients may connect, and when clients do, they are said to be associated with the access point. To obtain access to an access point, both the BSSID and the SSID are required.
  • Ad hoc networks have no access point for central coordination. Each node connects in a peer-to-peer way. This configuration is an independent basic service set or IBSS. Ad hoc networks also have an SSID.

Wireless network frames

802.11 networks use data framesmanagement frames, and control frames. Data frames convey the real data, and are similar to those of Ethernet. Management frames maintain both network configuration and connectivity. Control frames manage access to the ether and prevent access points and clients from interfering with each other in the ether. Some information on management frames will be helpful to better understand what programs for reconnaissance do.


  • Beacon frames are used primarily in reconnaissance. They advertise the existence and basic configuration of the network. Each frame contains the BSSID, the SSID, and some information on basic authentication and encryption. Clients use the flow of beacon frames to monitor the signal strength of their access point.
  • Probe request frames are almost the same as the beacon frames. A probe request frame is sent from a client when it wants to connect to a wireless network. It contains information about the requested network.
  • Probe response frames are sent to clients to answer probe request frames. One response frame answers each request frame, and it contains information on the capabilities and configurations of the network. Useful for reconnaissance.
  • Authentication request frames are sent by clients when they want to connect to a network. Authentication precedes association in infrastructure networks. Either open authentication or shared key authentication is possible. After serious flaws were found in shared key authentication, most networks switched to open authentication, combined with a stronger authentication method applied after the association phase.
  • Authentication response frames are sent to clients to answer authentication request frames. There is one answer to each request, and it contains either status information or a challenge related to shared key authentication.
  • Association request frames are sent by clients to associate with the network. An association request frame contains much of the same information as the probe request contains, and it must have the SSID. This can be used to obtain the SSID when a network is configured to hide the SSID in beacon frames.
  • Association response frames are sent to clients to answer an association request frame. They contain a bit of network information and indicate whether the association was successful.
  • Deauthentication and disassociation frames are sent to a node to notify that an authentication or an association has failed and must be established anew.

Top 15 Prominent Wireless Hacking Tools to watch out for in 2018 linux


There was a time when people relied on broadband and mobile data packs for connecting to the internet. With the influx of IOT in our day to day life, the use of WiFi has increased many folds. Every house has almost five to six devices which require internet to work efficiently. Homes have now become more digitally connected with heavy usage of smart TV’s, smart Ac’s, smartphones, laptops, smart alarms etc. Three components related to WiFi have also gone to the next level along with all other advancements:

  • WiFi protocols: We are well aware that the use of WEP has depreciated due to security weaknesses. The protocol stack has developed over time from being highly insecure to the highest level of security possible.
  • Hardware technology: Both the endpoints that use the WiFi and the WiFi router have become advanced. Routers used to come with a single antenna having a small signal range. Now the routers have a bigger range, better signal strength and multiple antennas pointed in multiple directions so as to kill the blind spots.
  • Wireless attacks: Public WiFi, free WiFi and personal hotspots on the go have increased the wireless playgrounds that the attackers can target. Attackers can hack into the network and can monitor the traffic in that network or crack the password and use your network for free. Just check the wireless networks that the laptop catches and you can see an example right there!

Before we start digging deep into wireless hacking, let’s get a few things straight:

Hacking/attacking unauthorized wireless networks is illegal. The article does not encourage the use of the aforementioned tools for the criminal purpose. These tools are to be used only for educational purpose and to try on your own devices or network. Things are not going to be straightforward; wireless hacking is not as easy as shown in hacking movies.

What is wireless hacking?

The increase in WiFi usage has led to increased wireless attacks. Any attack on wireless networks or access points which provides substantial information is referred to as wireless hacking. This information can be in the form of WiFi passwords, admin portal access, authentication attacks etc. To understand wireless hacking, one of the most important things to understand are the protocols involved in wireless networks. Attacks are mostly made on the internal steps of the protocol stack. IEEE 802.11 specifies the standards for wireless networks; let us discuss some algorithms that are used in WiFi networks:

  • WEP (Wired Equivalent Privacy):  WEP uses a 40-bit key and a 24-bit initialization vector. It uses RC4 for confidentiality and CRC 32 for integrity. Since the initialization vector is of 24 bits, there is a high probability that the same key will be repeated after every 5000 packets. WEP is a depreciated algorithm due to the various vulnerabilities identified and the fact that it can be cracked very easily.
  • WPA and WPA2: WPA was introduced as a temporary solution for the devices that did not support WPA2. WPA has now been broken and depreciated. The WPA2 is considered to be the most secure to date. The tools discussed further in the article will also cover details on how to attack WPA and WPA2 but the success of an attack depends on the time and the computing power.

Attacking Techniques


  • WEP cracking technique: WEP uses a 40-bit key which is 8 characters long. Once enough data packets are captured, breaking this key should not take more than a few minutes.
  • WPA/WPA2 cracking technique: Our devices have wireless passwords stored so that we do not enter the password on the same device again and again. The attackers take advantage of this by forcefully de-authenticating all the devices on the network. The devices will try to auto-connect to the access point by completing the 4-way handshake. This handshake is recorded and has the hashed password. The hashed password can be brute forced by using a rainbow table.
  • WPS cracking: This technology uses an 8 digit pin to connect to the wireless router. Brute forcing the 8 digit pin will give access to the router. Various tools use various optimization techniques to increase the speed of this attack and crack the key in a couple of hours.

You now have enough knowledge about WiFi hacking software to start your journey towards becoming a wireless password hacker.


Looking for how to hack WiFi password OR WiFi hacking software?

Well, a security researcher has revealed a new WiFi hacking technique that makes it easier for hackers to crack WiFi passwords of most modern routers.

Discovered by the lead developer of the popular password-cracking tool Hashcat, Jens ‘Atom’ Steube, the new WiFi hack works explicitly against WPA/WPA2 wireless network protocols with Pairwise Master Key Identifier (PMKID)-based roaming features enabled.

The attack to compromise the WPA/WPA2 enabled WiFi networks was accidentally discovered by Steube while he was analyzing the newly-launched WPA3 security standard.

This new WiFi hacking method could potentially allow attackers to recover the Pre-shared Key (PSK) login passwords, allowing them to hack into your Wi-Fi network and eavesdrop on the Internet communications.

How to Hack WiFi Password Using PMKID


how to hack wifi password software

According to the researcher, the previously known WiFi hacking methods require attackers to wait for someone to log into a network and capture a full 4-way authentication handshake of EAPOL, which is a network port authentication protocol.

Whereas, the new attack no longer requires another user to be on the target network to capture credentials. Instead, it is performed on the RSN IE (Robust Security Network Information Element) using a single EAPOL (Extensible Authentication Protocol over LAN) frame after requesting it from the access point.

Robust Security Network is a protocol for establishing secure communications over an 802.11 wireless network and has PMKID, the key needed to establish a connection between a client and an access point, as one of its capabilities.

Step 1 — An attacker can use a tool, like hcxdumptool (v4.2.0 or higher), to request the PMKID from the targeted access point and dump the received frame to a file.

$ ./hcxdumptool -o test.pcapng -i wlp39s0f3u4u5 –enable_status

Step 2 — Using the hcxpcaptool tool, the output (in pcapng format) of the frame can then be converted into a hash format accepted by Hashcat.

$ ./hcxpcaptool -z test.16800 test.pcapng

Step 3 — Use Hashcat (v4.2.0 or higher) password cracking tool to obtain the WPA PSK (Pre-Shared Key) password, and Bingo!

$ ./hashcat -m 16800 test.16800 -a 3 -w 3 ‘?l?l?l?l?l?lt!’

That’s the password of the target wireless network, cracking which may take time depending on its length and complexity.

“At this time, we do not know for which vendors or for how many routers this technique will work, but we think it will work against all 802.11i/p/q/r networks with roaming functions enabled (most modern routers),” Steube said.

Since the new WiFi hack only works against networks with roaming functions enabled and requires attackers to brute force the password, users are recommended to protect their WiFi network with a secure password that’s difficult to crack.

This WiFi hack also does not work against next-generation wireless security protocol WPA3, since the new protocol is “much harder to attack because of its modern key establishment protocol called “Simultaneous Authentication of Equals” (SAE).”
