Imagine you had two gas stations side by side and they both used a remote to change prices. Every time one changed the price it would change the price across the street. That would be a problem. There is no single file for every gas station in a country. Each must be unique for security. Since you have permission the best way to go is to record the transmission when the owner changes the price. If you find the code do not ever post the code with the name or location of the gas station though. The owner is being very kind to let you try. Changing the sign does not effect the pumps but it will make the customers very angry so be responsible.

It might seem a bit bold, but since people working in the gas-station just do their job, if the person behind the counter seems not to old and grumpy, just ask how those are changed and try frequency analyzer? I might sound stupid but you would be surprised on how many people actually would tell/show you if you just ask and mention your interest in the topic. Heck , I you find that it is also vulnerable, and you contact the manager you might even get a free tank of fuel for notifying them.

But then again, gas station clerk, mostly sitting out hours bored anyways, especially if it is a night 24/7 gas-station, they are not there cause they like the job but cause they need to work for income. A fun talk and jerking around with some local stuff might even amuse them.

My personal experience with people working at a gas station for some reason is only positive , i except some old grumpy people watching the clock till they can go home again they would just tell you to fck off.

Some are already on GitHub. You may need to be patient while capturing Weather station signals. It may take as long as a minute between transmissions. You must be on the correct frequency when it transmits.

Once you install the Marauder firmware on the WiFi dev board, you can connect the dev board to the Flipper Zero GPIO header and connect the flipper to your PC or Android phone via USB cable.

On the Flipper Zero, navigate to GPIO>USB-UART Bridge. I keep my Bridge configured to use USB channel 0

Note: We now offer a dedicated SD adapter and SD/GPS adapter board for a clean install on the Flipper Zero WiFi Dev Board. No wires are necessary.

A MicroSD card can be attached to the Flipper Zero WiFi Dev Board SPI via a MicroSD Breakout. Attaching a microSD card to the Flipper Zero WiFi Dev Board will allow the Marauder firmware to save captured WiFi traffic to storage in the form of PCAP files to be exported for analysis later. If you install this mod, DO NOT use the flipper_sd_serial.bin to update your WiFi Dev Board. Refer to the following table for the required solder connections

Select or deselect access points and/or stations for targeted attacks. You must provide a comma separated list of indices of the desired access points and/or stations from list.

Any specified indices which were NOT already selected will become selected. Any specified indices which were already selected will no longer be selected

select -a 1,3,5: Selects APs at indices 1, 3, and 5

select -a all: Selects all APs in the list

select -c 3,4,29: Select stations at indices 3, 4, and 29

select -a -f "equals 'E CORP' or contains EVIL": Select all APs who's ESSIDs are equal to E COPR or contain EVIL

Here are what some cybersecurity vendor experts are saying about the juice jacking news, including a couple who do not view the problem to be as bad as reported, and others considering the implications for electric vehicles (EV) charging stations:

In today's article, we are going to cover how to deauthenticate some Wi-Fi-connected cameras using the flipper ESP32-S2 developers board flashed with the marauder firmware by justcallmekoko . We'll also cover how to sniff for deauthentication frames and how you can protect yourself against it.

Here is a list of what we are going to cover in today's article:

 

 - What a deauthentication attack is.

 - How a deauthentication attack works.

 - A demonstration of deauthenticating a wireless camera.

 - How you can try to mitigate this kind of attack.

 - How we can detect an ongoing attack.

 

 And finally what other alternatives are there to the flipper zero developers board.

 

 NOTE: Flipper Zero Firmware used during these videos.

 

 I would like to point out I am going to be using the Official Flipper Zero Developers Build Firmware with the Marauder Companion App which I have compiled for this release of the firmware.

 

 We are not going to cover compiling the FAPs in this article as there is already some great documentation available for this on the [Flipper Zero GitHub page].

A deauthentication attack is a wireless attack in which an attacker will send multiple deauthentication frames to a station to overwhelm them which can result in a denial of service to either a selected station (client device) or to every station on the network. 

 

 This would allow for the attacker to combine this with another attack called the Evil Twin, or even use this to capture a 4-way handshake which could be cracked using a dictionary attack to obtain the Access Point's passphrase, which we are not going to cover here as we are purely focusing on the deauthentication attack.

 

 It is worth mentioning the Flipper ESP32-S2 Developers board operates on 2.4GHz only, and as such, this particular attack will only work if the devices are connected to the 2.4GHz network on your wireless Access Point.

 

 Luckily for us, our cameras are sitting on the 2.4GHz network.

 

 How Does A Deauthentication Attack Works:

 

 The attack works by broadcasting multiple deauthentication frames using the selected Wireless Access Point's MAC address and a special broadcast address of FF:FF:FF:FF:FF:FF this will transmit to all stations on a wireless access point.

 

 The deauthentication frame is implemented in the IEEE 802.11 Wi-Fi standard as a way for telling a station that its connection is being terminated, this works both ways from a station to an Access Point and from an Access Point to the station.

 

 There's something we need to know though before we dive into an example and that is, what is the difference between a Wi-Fi association frame and an authentication frame.

 

 Authentication: The connecting device opens a line of communication to the Wireless Access Point containing the devices identity (MAC). The WAP then sends a response of an success or failure, there is no encryption or security available at this point.

 

 Association: After authentication has received a success response a association request is sent containing information such as SSID the client wants to connect to, encryption type, supported channels and other 802.11 capabilities. If the 802.11 capabilities of the client match that of the WAP a Association ID (AID) is assigned and a response with a success message is sent granting full access to the WAP.

 

 In most home routers you will both authenticate and associate at the same time and of course if you need to disconnect you will both disassociate and deauthenticate at the same time.

 

 Though in a larger network made up of multiple Wireless Access Points it is possible to disassociate from one access point and associate to another while remaining authenticated to the same network.

 

 Let us look at an example for a deauthentication frame: You are at home on your Wi-Fi and you notice your internet is slow, you told your neighbour they can use your internet while theirs is down, you check the connected devices on your Access Point's web configuration page and you notice the neighbour is taking up all of the bandwidth on the network.

 

 You add their device to a Blocklist so you are able to freely browse the internet again, when you add them to the blocklist a deauthentication packet is received and the station will disconnect from the Wireless Access Point.

 

 Because of the way IEEE 802.11 is designed a deauthentication frame is a notification, not a request that a device must comply and deauthenticate from the Access Point. This cannot be refused unless Protected Management Frames are enabled also called Management Frame Protection or MFP for short, which we will talk about later.

 

 When this disconnect happens a reason code is also supplied within the data frame sent from the Access Point to the Station telling the Station the reason why it is being deauthenticated. In this above example, it will be the reason code 4 - Disassociated due to inactivity. At least this is what I found during my testing when I added a client device to the blocklist.

 

 This is precisely what we are doing with the flipper deauthentication attack, the flipper is transmitting an Ethernet Broadcast Address which is a special address used to transmit data to any available stations that are associated with the selected access point, with a reason code of 2 (Previous authentication is no longer valid) to deauthenticate all clients on the network.

 

 This happens in the background and you cannot see the frames being sent unless you have a second flipper with a developers board or a network adapter with a supported chipset to be able to sniff the traffic for deauthentication frames.

 

 Because we are sending it to any available stations this also means that the Source Address and Transmitting Address must come from the Access Point (or appear to) otherwise the stations associated with the access point will ignore the broadcasts. This also means you do not need to populate a list of stations associated with the access points before launching the attack.

 

 It is worth mentioning you can broadcast deauthentication frames from multiple access points, however, the more you select the less effective the attack will be because more time is taken to broadcast each deauthentication frame with the spoofed MAC address of the selected AP, and so when a disconnect happens the station will immediately try to reconnect if we send a frame too slow then the station will connect back to the Wireless Access Point, this is not what we want as the goal here is to keep the station disconnected for as long as we want. 006ab0faaa
