WiFi Client Hacking

Essentially, the ability to breach through wireless network clients involves networking technologies, hacking principles, and command-line tools that simultaneously exploit the inherent lack of encryption and IT security innovation in the wireless front as well as the common vulnerabilities found in major propriety operating systems like Windows, Mac OS X, and Linux.

Because of the facts that Windows is notoriously error- and vulnerability-prone (especially first-time releases), Windows 10, Mac OS X takes so long to address the myriad of bugs that it sports, and Linux systems are nearly clones of each other regardless of the variant are also very beneficial to hackers when it comes to hacking WEP, WPA, and WPA2 protocols.

Public WiFi network connections mostly work this way

First off, a client first has to get a packet (also known as a beacon management frame) from a nearby access point in order to work.

If there are multiple beacons present, a client will choose which of the available Basic Service Sets it can join.Windows XP users will even be presented with a list of SSIDs representing the networks that they can connect to at their behest.

Probe request management frames can also be transmitted by the client at any access point as well to ensure uninterrupted connection.

Once the command-line programs are executed and the WEP or WPA encryption process starts, the attacker can commence his own operation by using a sniffer program to find wireless gadgets running in peer mode.

This should enable him to gain root access to a system in the long run (a very dangerous circumstance to be sure, because at this point of no return, the hacker has already bypassed the main defenses of your mobile or wireless connection).

From there, he'll probably deploy a key logger or a precisely placed Trojan horse that will allow him to cripple your network system to the point where he has complete control over it, exploiting each and every last inherent weakness that's been outlined thus far.

The WiFi client hacking attack described above can be done even if the victim is traveling and only using his laptop at an airport or hotel lobby.

In fact, as long as an unsuspecting user is surfing via an exposed and public "Free WiFi" area, a cyber attacker can pretty much do anything he wants and use all sorts of methods to begin his invasion.

Keep in mind that public wireless Internet is an open channel, so in order to make it available to as many people as possible, it will have to expose itself to hackers as well; that's the true price of using a complimentary WiFi service. 

WiFi Client Vulnerability

Clients can be found on both wired and wireless networks.

A client could either be a server, a printer, or even a NAS (Network Attached Storage) device.

Usually, makeshift networks that had been setup from out of the blue without any prior planning whatsoever lack any printers or servers; the only thing present in these ad-hoc installations are other people's machines, because a network of computers is the easiest type of network to establish. A client can also be used by crackers to run amok on any given notebook PC or PDA using wireless technology.

What's more, there are many ways for a cracker to crack through the passwords or passphrases used for WPA or WPA2 protocols; if you're using the outdated WEP standard, you're even more susceptible.

With that said, when it comes to WiFi client protection

Several important factors and circumstances must be considered in order to ensure your wireless connection's overall security.

For instance, because the majority of users have no idea how to protect their machines from the ravages of cyberspace and since most propriety operating systems being used in personal computers nowadays are Microsoft-based (which means they're susceptible to hacker attacks), dedicated and competent crackers have plenty of wiggle room to use when it comes to doing what they do best.

The combined factors of the notoriously threat-prone Windows 10 operating system and the general ignorance of the everyday, average user when it comes to cyber security allows hackers quite a lot of leeway to pretty much do whatever they want to a WiFi client.

Moreover, a laptop that uses a wireless connection is one of the most exposed and hacker-vulnerable setups in existence.

To be more exact, an office notebook or any other mobile device that is linked to the Ethernet can still have its Wireless Network Interface Card installed and configured in peer mode although the office from which it came from has not submitted a WiFi network, thus leaving it exposed to hacker attacks by default.

A Wireless Network Interface Card operating in peer mode can also deploy the probe request frames usually involved during wardriving expeditions.

These probe request frames are delivered at regular intervals in an effort to link up with another gadget that has an identical SSID.

Ergo, NetStumbler or any other wireless sniffer program can then be utilized in order to locate wireless devices configured in peer mode.

From there, a hacker could connect to the laptop and exploit any number of its vulnerabilities at his behest, which would then allow him root access to the machine.
