Make WiFi Jammer With ESP8266 - Hack Any WiFi Without Password!

While our focus is not thought to be used for high-profile criminals such as organized crime who will often use jammers, we are aware that this is, to our knowledge, the weakest link in our system. Thankfully it is a weak link that is very rarely exploited by the more common adversaries found in our adversary model, and we do not pretend to handle situations for such cases. So, while this is not really a practical issue, as a technical person I can't wonder but think if there's any way that we could actually protect against jammers while still using common protocols.

Is there any strategy? This is not my area of expertise, so I am nearly clueless, but as far as I know, frequencies that are high enough in the spectrum are reserved for other uses, so we can't even change to them, and strategies like frequency hopping don't work with said protocols.

I'm lost, to be honest. Thank you. Jamming is the radio equivalent of shouting. The jammer drowns your communications under a lot of noise.

Defence against jamming usually is a combination of the following:. Power : speak louder. Of course, this increases energy consumption and heat dissipation, and it is not necessarily workable with your devices at hand.

Tightening : try to use directional radio beams. The sender will send a non-isotropic signal, much stronger in one direction than in any other; the receiver will also concentrate its reception ability on this specific direction. This has been used in aircraft navigation systems see this. This kind of solution requires directional antennas, and, more importantly, proper orientation: the sending device must know the approximate direction of the receiving station, and vice versa.

Frequency hopping : switch frequencies over a large range of possible frequencies. Sender and receiver agree upon the sequence of frequencies that they will use. This relies on the idea that it is much harder to jam a large spectrum than a single well-defined frequency. Note, though, that in normal marketable equipment, frequency ranges are legally constrained, and it is still relatively easy to jam all frequencies which have been allocated to GSM and 3G.

Retaliation : a jammer is an active attacker; it emits a strong signal.First of all, it is GSM frequency that causes so many problems for lots of people out there. And there is much more than those people which like to talk via cell phone too much in public places. GSM bands might be used in technologies like Cell ID to triangulate the location of cell phone user between three closest cell phone towers.

Such technologies are used by the government and large corporations to find out where you are.

In addition GSM signals might be intercepted and used for eavesdropping of your conversations in real time. However, the usage of simple GSM jammer will not be enought, you also need to be sure that other frequencies are blocked as well. Our jammer shop offers you both portable and desktop signal jammers which will be able to jam GSM and 3G.

The next one in our list is GPS tracking satellites. GPS and other satellite signals might be used not only by your navigator but also by the hidden tracking device under your car put there by law enforcements or some bad guys who need to know your exact location. Not only GPS tracking devices are used to track your location but GPS module of your smartphone might be used for this purpose as well.

So Jammer Store offers you GPS jammers for sale which designed to prevent any kind of satellites tracking your movements in vehicle or on foot. But the tracking industry is constantly in the state of development thus more and more complex trackers are appearing and more advanced location finding technologies are used.

As a result of this development new type of tracking devices has appeared. This technology is a combination of cell phone tower triangulation mentioned earlier and satellite location tracking we used to. It means that usage of a single GPS jammer will not help you in this situation, you will also need a strong cell jammer to stop unauthorised tracking.

That's why Jammer-Store. Each jamming device has the ability to jam mobile phone and GPS frequencies at the same time, so you don't need to buy two different devices for this purpose. There are many other threats of the modern world related to the wireless frequencies like Wi-Fi and Bluetooth connections, devices which use low frequency bands in their work and many more. If you want to familiarize yourself with all those threats and devices which can protect you from them — please visit the category pages of our site devoted to those particular wireless threats and methods of solving them.

Arduino: 1. Reply 2 months ago.Military trade shows are usually a pretty depressing affair: a bunch of middle-aged white guys in bad suits fingering rubber rifles, watching combat videos set to bad rock songs and bragging about their company's latest tank, radio or whatzit. But this morning during presentations at the Association of the U. Army show in Fort Lauderdale, Florida, I was jolted out of a depressed stupor when an Army officer slapped a slide up on the projection screen that showed seemingly random points connected by lines: a classic representation of an international terrorist network or insurgent bombmaking cell.

Then he smiled and said he was going to show us how. Graham is a professor at West Point, where he teaches future officers the very thing he was showing us.

The slide, he explained, was in fact a representation of his department: its instructors, students and partners in the Army. That there are three major vulnerabilities in networks:.

Assuming your resources for attacking a network are limited — and in the real world, they always are — who do you hit? Graham asked. Using his own department as an example, he advocated killing just three of the dozens of members.

Surprisingly, none were examples of density or centrality, since those were all situated in the meaty middle of the network. The network had enough redundant connections to quickly repair itself after their demise. What Graham wanted to do was hit the network where there were no redundancies, so all of his targets were boundary spanners. By taking out three spanners, Graham showed how you could isolate relatively homogeneous chunks of the network, rendering it stupider and less adaptive than before.

Funny thing is, the spanners in Graham's department's network were mostly low-ranking members such as cadets. Just goes to show, when attacking networks, the most obvious targets aren't always the most important. Tactics, Strategy and Logistics. View Comments. Sponsored Stories Powered By Outbrain.

We will get through this together. Updated: March 29, References. To jam a network, you need to broadcast radio signals on the same frequency, overpowering the original signal. Jamming devices that broadcast on a wide range of frequencies at once can disrupt everything from police radar to GPS systems, and are illegal in many countries. You can use your own WiFi router instead, or another wireless device that broadcasts on a more narrow range of frequencies.

When the four-ounce envelope arrived from New York three days later, it looked innocuous enough. It contained a finger-sized black plastic box, a small black antenna to screw onto that box, and two glass fuses. You just need to be looking in the right channels. The sale and use of jammers, even by policeis a federal crime with punishment ranging from fines to prison time. When one of them is in use, those systems can go haywire. The Global Positioning System relies on precise time data being sent from 31 satellites equipped with atomic clocks in space; a receiver calculates its location by determining its precise distance from a handful of those satellites.

Depending on the broadcasting strength of the jammer, it can knock out GPS reception for a few yards or for miles. In Juneplanes flying into Northeast Philadelphia Airport kept reporting that they were losing the GPS signal on the last mile of their approach. An agent from the Federal Communications Commission FCCwhich enforces prohibitions against jammers, came to investigate and discovered a truck in a nearby parking lot.

This is what can happen when technology built for—and still necessary for—high-grade military purposes becomes available to the general public for personal, and often petty, applications.

People trying to avoid their annoying bosses end up taking out navigational systems everyone depends on.

The military has been planning for years to set up a more secure GPS system, but it is perpetually delayed. So instead the government is protecting this critical infrastructure by outlawing jammers.

I was leery of breaking the law to test my brand new GPS jammer, so I never used it, but I found people online willing to document their success. In a YouTube video, a man happily demonstrated how well his jammer worked and directed watchers to a site that sells them in exchange for Bitcoin.

He plugged his jammer into a power outlet in his dashboard, causing the fleet-management tracking device in his vehicle to lose its GPS signal. I went with the U. After the seller shipped me the jammer from Sheepshead Bay, Brooklyn, I reached out, identifying myself as a journalist, and asked to talk.

Ryan Moore, communications director for eBay, said GPS jammers are prohibited on the site and that sellers who circumvent eBay filters that prevent listings of these goods may have their accounts suspended.

To try to see the devices in use, Gostomelsky, who works for the security firm Spirent Federal—which, it should be disclosed, sells equipment designed to detect jammers—set up GPS signal monitoring equipment in his hometown of Philadelphia, in San Jose near the Spirent office, and briefly in Washington, D. His equipment is programmed for its particular location, locks onto 12 satellites, and starts listening; it knows a jammer is nearby when there are changes or interruptions in the signals being sent by the distant satellites.

He wanted to find out just how popular the forbidden devices actually are. In the course of eight months, the five stations he set up, which could detect unusual activity up to a mile away, detected GPS jammers 78 times, deployed by 19 different people or groups of people. Some of the ways the jammers were being used, though, surprised him.

While he was at the Washington Hilton in D. Gostomelsky mounted the 20 pounds of hardware on his back and tracked the signal to a high school gym, inside of which kids were flying drones. According to reports on Redditcheating Pokemon Go players turned to the devices last year. The game overlays virtual creatures and arenas on the real world via a smartphone app; players have to go to those real world spots with their phones in order to collect creatures or to battle for control of the arenas, called gyms.

Another Reddit user who said he was on the security team for an Australian aerospace company complained that Pokemon Go players were putting jammers around virtual gyms in airports and were affecting aircraft operations. But most of the jamming Gostomelsky saw was done for the sake of profit or paranoia.

Gostomelsky lives near Interstate in Pennsylvania, and would regularly detect GPS jammers in use as tractor-trailers went through the toll booths. Because the toll-taking for commercial trucks relies on GPS tracking, they can avoid paying through jamming. Gostomelsky wanted to be able to identify exactly who was doing the broadcasting, so he included in his five suitcases four microcomputers with software-defined radios—devices that decipher radio signals. These picked up on a variety of signals that might be traveling along with the jammer: the list of wi-fi networks and Bluetooth connections a device was programmed to look for; broadcasts being made on radio frequencies typically used by law enforcement and security guards; and the signals sent by tire pressure monitoring systems.

The last one is particularly novel—car tires wirelessly broadcast a unique number to the car telling it if the pressure in the tires is getting low; his device picked up on that transmission, letting him identify particular cars. Oftentimes it was obvious to Gostomelsky why a particular person was using a jammer. People driving company trucks wanted to avoid being tracked on their lunch breaks by navigational devices installed by employers and they would tell Gostomelsky that when he walked up to the cars and knocked on their windows.

Stephanie Voelker, a product manager at Geotab, which makes fleet tracking devices, told me their devices note every time GPS connectivity is cut off.HPJ is a kind of device different from the most products of this category.

It is a bigger model that is developed to transmit very powerful output but not be used as handheld device. With such powerful output you can block almost all mobile phons to avoid any cell phone signals in the area between meters. HPJ is a signal blocker device that is meant to be installed at meeting room, conference area, museum, library, cinema or school.

It also has a car adapter as its smaller analogues but when it works at your meeting room, the whole area is absolutely protected against eavesdropping technologies based on cell phone networks, any kinds of mobile phone tower triangulation or breaking into your smartphone to get your private data from it.

One of the greatest features of this GSM, 3G blocker is ability to use a remote control to operate the jammer. You will not find any other device with this specifications on the market.
