These include conducting DDoS attacks that can disrupt communications between connected devices and the network server so companies can’t receive any data.Īttackers also can use the keys to intercept communications and replace these with false data, such as fake sensor and meter readings. Once bad actors obtain the encryption keys for a LoRaWAN network, they have a number of attack options available “to compromise the confidentiality and integrity of the data flowing to and from connected devices,” IOActive researchers wrote.

Other ways hackers can obtain encryption keys to LoRaWAN networks include by compromising the system of the device manufacturer responsible for installing the firmware with device keys hacking the devices or computers of technicians responsible for deploying devices where the keys might be stored obtaining the keys from flash drives or emails of clients or device manufacturers where they were disclosed and shared breaching a service provider who had keys stored in their backups or databases or obtaining an AppKey in a dictionary or brute-force attack, researchers wrote.

These methods include: using reverse engineering to “sniff” keys from devices obtaining keys from device tags displaying the code administrators forgot to remove before a device was placed in its final location stealing source code for a device from open-source repositories or vendors websites guessing keys that show lack of sufficient randomness or cracking a network with default or weak credentials or other security vulnerabilities and stealing the keys from these servers. The problem with this architecture is that the keys are surprisingly easy to obtain for people who aren’t supposed to have access to the network or devices, researchers found, who outline numerous ways bad actors can obtain the keys to LoRaWAN networks. Session Keys and Functions in LoRaWAN v1.0.3 These keys are “the source of the network’s only security mechanism, encryption,” and thus, once cracked, basically give hackers an open invitation to the devices and networks being protected by them, researchers noted. The application-layer security is responsible for confidentiality with end-to-end encryption between the device and the application server, preventing third parties from accessing the application data being transmitted.Įach layer of protection depends on the security of two encryption keys–the Network Session Key (NwkSKey) and the Application Session Key (AppSKey), both of which are 128 bits long. The network-level security ensures the authenticity of the device in the network, providing integrity between the device and the network server, they wrote. The LoRaWAN protocol defines two layers of security: one at the network level and another at the application level, researchers described in the report. of the protocol, there are four key elements that shape a LoRaWAN implementation. “As a result, users are blindly trusting LoRaWAN networks and not paying attention to cyber security however, implementation issues and weaknesses can make these networks easy to hack.” In version 1.0. “The LoRaWAN protocol is advertised as having ‘built-in encryption’ making it ‘secure by default,’” he wrote in the report.

Indeed, it’s the perception that LoRaWAN is inherently secure that makes it so dangerous, noted Cesar Cerrudo, CTO at IOActive, the lead author of the report, “LoRaWAN networks susceptible to hacking: Common cyber security problems, how to detect and prevent them.” Moreover, it’s currently impossible for organizations to know if a LoRaWAN network is under attack or if an encryption key has been compromised, making defending such attacks perilous, they said. In reality, LoRaWAN encryption keys are easily obtained by a savvy hacker to conduct DDoS attacks and send false data to networks, researchers have found.

Users and developers of IoT devices in smart cities, industrial IoT, smart homes, smart utilities, vehicle tracking and healthcare have widely embraced the protocol because of the false sense of security its encryption provides, according to a report by IOActive released Tuesday. LoRaWAN, or Long Range Wide Area Networking protocol, allows low-powered devices to communicate with internet-connected applications over long-range wireless connections.

However, bad implementations and security flaws make the protocol a real blind spot in the fraught world of IoT security, as LoRaWAN is easily susceptible to threats that could cause widespread disruption and even destruction if it’s not implemented correctly, IOActive researchers have found. The LoRaWAN protocol has become standard in the world of industrial IoT because of its support for low-power wireless devices over long distances and its end-to-end encryption technology.
