Hacking Iridium Satellites With Iridium Toolkit - RTL-SDR, Sep 2019
"Over on YouTube TechMinds has uploaded a video showing how to use the Iridium Toolkit software to receive data and audio from Iridium satellites with an Airspy. Iridium is a global satellite service that provides various services such as global paging, satellite phones, tracking and fleet management services, as well as services for emergency, aircraft, maritime and covert operations too. It consists of multiple low earth orbit satellites where there is at least one visible in the sky at any point in time, at most locations on the Earth.

The frequencies used by the older generation Iridium satellites are in the L-band, and the data is completely unencrypted. That allows anyone with an RTL-SDR or other SDR radio to decode the data with the open source Iridium Toolkit."

Cf. https://www.rtl-sdr.com/talk-decoding-data-from-iridium-satellites/ : "they discuss how Iridium security is moderate to relaxed, pointing out that Iridium claims that the majority of ‘security’ comes from the complexity of the system, rather than actual security implementations"

Help Support RadioCapture – A Project that Records Entire Trunked Radio Systems and Provides Online Access to Audio
RadioCapture.com is a website run by Matt Mills that is capable of automatically capturing trunked radio communications from various agencies such as the emergency services and creating publicly accessible historical and live logs of the audio. This is a concept different to radio scanner streams, as all audio is logged and historical audio can be accessed easily at any time.

Spoofing GPS Locations with low cost TX SDRs, RTL-SDR Sep 2015
At this years Defcon 2015 conference researcher Lin Huang from Qihoo 360 presented her work on spoofing GPS signals. Qihoo 360 is a Chinese security company producing antivirus software. Lin works at Qihoo as a security researcher where her main job is to prevent their antivirus software and users from becoming vulnerable to wireless attacks. Her research brought her to the realm of GPS spoofing, where she discovered how easy it was to use relatively low cost SDRs like a USRP B210/BladeRF/HackRF to emulate GPS signals which could allow a wireless attacker to manipulate the GPS on smartphones and cars.

Showing the HF Interference Problem from Ethernet over Powerline Devices - rtl-sdr.com
Over on our YouTube channel we’ve uploaded a new video that shows how bad the interference from Ethernet over Power devices can be. Ethernet over Power, Powerline Networking, Powerline Communications or ‘HomePlug’ is a technology that allows you to use any of your household power outlets as an internet Ethernet port, completely eliminating the need for runs of Ethernet cabling. They are capable of high speeds and can be used anywhere in the house assuming the two plugs are on the same power circuit.

Unfortunately these devices tend to wipe out almost the entire HF spectrum for anyone listening nearby.

USBee: Leaking Data from Air-Gapped Computers and Receiving it with an RTL-SDR - rtl-sdr.com - Aug 2016
This Monday researchers from Ben-Gurion University of Negev released an academic paper detailing their research in showing how attackers could cause your PC to wirelessly leak data. They write that usually covertly modified USB devices are required to leak data, as is the case with the NSA’s COTTONMOUTH device which is detailed in their ANT catalog. However, the innovation from these researchers is that their own implementation can be used to turn any unmodified USB device into a make shift transmitter.

Unlocking Almost Any Vehicle with an SDR or Arduino - rtl-sdr.com
"researchers from the University of Birmingham have discovered two vulnerabilities that can be used to unlock almost any car. The first vulnerability concerns Volkswagen Group vehicles (VW, Audi, SEAT, Skoda) sold since 1995. Essentially their research found that the keyless entry systems of VW Group vehicles relies only on a few global master keys which they have been able to recover through reverse engineering of an undisclosed component used in a VW car. Then by sniffing the wireless key’s signal with an RF module or SDR like the RTL-SDR or HackRF they are able to recover the cryptographic algorithms used and then using the global key clone the wireless key signal, which can then be re-transmitted with a simple Arduino.

In their second research findings, the researcher’s write how they have been able to crack the Hitag2 rolling code system which is used in many vehicles such as Alfa Romeo, Chevrolet, Citroen, Dacia, Fiat, Ford, Lancia, Mitsubishi, Nissan, Opel, Peugot and Renault. Again, the hack works by sniffing a few wireless keyfob rolling code signals with an SDR or other device. Once the signals have been sniffed a simple laptop computer can reportedly break the encryption within one minute."

Motherboard: How Hackers Could Wirelessly Bug Your Office - rtl-sdr.com
Cui shows how he infected a desktop telephone, as well as a desktop printer. The malware running on the phone causes the phone to transmit an RF signal of the voices heard by the microphone, and the malware running on the printer causes the printer to emit a binary coded transmission of the text being printed. The malware is able to do this by forcing a GPIO, PWM or UART interface on the printer to modulate in a similar way to what is done with the Raspberry Pi FM transmitter project, rpitx. To receive and decode the signal Cui uses a software defined radio and a GNU Radio program.

Remote Spectrum Monitoring Drone with OpenWebRX, Raspberry Pi and an RTL-SDR - rtl-sdr.com
"Recently Zoltan of rfsparkling.com wrote in to us to show us how he combined efforts with András (programmer of the OpenWebRX software) to create a proof of concept remote spectrum monitoring drone. The drone uses an RTL-SDR connected to a Raspberry Pi, and the Raspberry Pi runs an OpenWebRX server which broadcasts the radio data via 4G mobile internet."

Stealing a Drone with Software Defined Radio - rtl-sdr.com
PHDays (Positive Hack Days) is a yearly forum with a focus on ethical hacking and security. During this years forum which took place in June, the organizers set up a competition where the goal was to “steal” or take control of a Syma X8C quadcopter drone. The drone runs on the nRF24L01 module, which from previous posts we have seen can easily be sniffed and decoded with an RTL-SDR or other SDR.

To reverse engineer the drones wireless communications system the teams used software defined radios like the HackRF and BladeRF, and also an alternative method involving just using an Arduino and nRF24L01+ receiver chip.

Building a simple NOAA APT Antenna out of an Umbrella - RTL-SDR
"n order to optimally receive NOAA weather satellite images a special satellite antenna tuned for 137 MHz should to be built. Generally either a QFH or turnstile antenna is recommended as these receive signals coming from the sky very well. If you are interested in receiving weather satellite images from NOAA satellites with an RTL-SDR dongle then we have a tutorial available here."

HACKING ALARM SYSTEMS WITH AN RTL-SDR AND RFCAT
"Back in 2014 the author of boredhackerblog.blogspot.com did a final year project for his wireless security class on hacking home alarm systems. His presentation was titled “How we broke into your house”. In his research the author used both an RTL-SDR and a simple RFcat wireless transmitter and performs a simple replay attack on a cheap $50 alarm system. "

Reverse Engineering the SimpliSafe Wireless Burglar Alarm - rtl-sdr.com Feb 2016
SimpliSafe is a home security system that relies on wireless radio communications between its various sensors and control panels. They claim that their system is installed in over 300,000 homes in North America. Unfortunately for SimpliSafe, earlier this week Dr. Andrew Zonenberg of IOActive Labs published an article showing how easy it is for an attacker to remotely disable their system. By using a logic analyser he was able to ... discover which packets were the “PIN entered” packets. He then created a small electronic device out of a microcontroller that would passively listen for the PIN entered packet, save the packet into RAM, and then replay it on demand, disarming the alarm. A few days later Micheal Ossmann (wireless security researcher and creator of the HackRF SDR and YardStick One) decided to have a go at this himself, using a YARD Stick One and a HackRF SDR.... he is able to recover the actual PIN number entered by a home owner from a distance ...

Review: Airspy vs. SDRplay RSP vs. HackRF - rtl-sdr.com
"When people consider upgrading from the RTL-SDR, there are three mid priced software defined radios that come to most peoples minds: The Airspy, the SDRplay RSP and the HackRF. These three are all in the price range of $150 to $300 USD. In this post we will review the three units and compare them against each other on various tests."
