What would you do if you found a suspicious-looking IoT (Internet of Things) device under your desk at work? If youre an employer, how do you install innocuous IoT devices in your office building with raising concerns from your employees? If you want to produce your own IoT devices, how do you ensure that theyre ethical, legal, and secure?

Erich Styger answers all of those questions in a log of his journey through reverse-engineering an IoT device found in a real office.For ethical and probably legal reasons, Styger doesnt say where exactly this device was found, nor who designed or manufactured it. He was been in contact with the manufacturer to let them know about the flaws he found, but his post is mostly intended for educational purposes. These particular devices were found mounted throughout a work space, including under employees desks. Each IoT device was mounted magnetically and easily removed, but their purpose wasnt clear. That, in itself, is the first red flag. Employers should never install monitoring equipment without their employees knowledge. Most of the rest of the red flags deal with the security of the hardware, which was full of vulnerabilities. Inside the easily-opened case was a PCB with a LoRa module and antenna, an STM32 Arm Cortex-M0 microcontroller, a humidity/temperature sensor, a PID motion sensor, and an accelerometer that was apparently left unconnected. As it turns out, the device was intended to simply monitor the environmental conditions through the office, and was triggered by motion via the PID sensor in order to save battery life. However, Styger found multiple ways to intercept that data, and even methods to inject false data. The easiest way to gather the data, and more importantly the secret app key, was to simply pick it up when it was transmitted between the microcontroller and LoRa module, because it was sent as clear text.

With that information, the device could be spoofed through the LoRaWAN network. The debug pins and functions were even left accessible, so the devices firmware could be copied, reverse-engineered, and modified. Basically, if youre looking for a thorough explanation of what not to do when designing an IoT device that should be secure, Stygers blog post is perfect RELATED QUESTION I didn't get Google Glass Explorer Edition. Is trying to learn Glass dev without the hardware a futile effort? No, you can still learn the fundamentals of Glass development without the hardware. There are three main approaches for accomplishing this: 1) Visit the Mirror API documentation, get into the playground, and start hashing up some code. Download the PHP, Java, and Python library, whichever you're most comfortable with. Familiarize yourself with the jargon and converntions (timeline, bundles, menus, etc). Read the support documentation (second link below) to see how the Glass hardware actually functions. Build some apps to this specification. Soon enough, you will find a friend with hardware to t

With the continuous improvement of people's living standards, more and more cars enter ordinary people's homes. Owning cars not only improves residents' living standards, but also gradually produces the problem of easy to buy cars and difficult to find parking spaces., Although the real estate developers have made plans in the development of parking, the plans have failed to catch up with the changes. Today, the total number of parking spaces owned by the community is far less than the number of vehicles. In order to deal with the difficult parking problem, many communities have installed license plate recognition parking lot systems! Why can the license plate recognition parking lot system effectively alleviate the difficulty of parking? 1. License plate recognition technology is safe and convenient. License plate recognition is one of the important components of modern intelligent transportation system. Based on digital image processing, pattern recognition, computer vision and other technologies, analyze the vehicle image or video sequence captured by the camera to obtain the unique information of each vehicle. It can not only record the real name information of the vehicle, but also make the vehicle more convenient and fast when entering and leaving the parking lot. 2. Supporting popular mobile payment is also an urgent part of the parking problem. In recent years, the rise of mobile payment, the popularity of WeChat payment and Alipay payment has provided a train of thought for solving the problem of long time of entrance and payment. Mobile payment has increased the efficiency of payment, saved the time of owners, and improved the utilization rate of car park parking spaces. The intelligent parking lot charging system will automatically send parking records and parking fees to the owner's mobile payment account. After verification, the payment and payment process will be completed automatically. 3. The reverse car search function helps car owners quickly find cars in large parking lots, such as shopping malls, shopping centers and large residential areas. Due to the similar environment and signs in large parking lots, car owners often fail to find where their cars are parked when returning to the parking lot. The license plate recognition parking lot system has the reverse vehicle retrieval function, which allows users to search the license plate number, display the location of the owner and the vehicle, and help the owner find the area where the vehicle is located. For the parking problem in the community, it not only needs to add new functions to the license plate recognition parking lot system, but also needs the support of the government to solve the property right disputes of underground parking spaces, so that developers have no worries about building underground parking lots. In the case of using scarce resources such as land, parking spaces designated from community roads shall not be used for profit. This is an important way to solve the problem of parking in the community.

Empty vehicles shall be driven in the rightmost lane of the license plate recognition system, and taxis and online car Hailing shall actively yield to pedestrians and non motor vehicles. Do not stop on the road at will to get on and off passengers; The bus shall run in the special lane. When turning and changing the lane at the intersection, it shall merge at the Yellow grid line. When there are many vehicles queuing at the intersection and passing slowly, it shall wait outside the parking line at the intersection to prevent congestion at the intersection. To further optimize the road traffic environment, our reporter (reporter Sun Huifang) created an effect to consolidate the "national civilized countryside". According to the arrangements of the provincial capital civilization Committee and the Municipal Public Security Bureau, the traffic management department decided to carry out the "warm road action" in the main urban area from now until the end of the Spring Festival next year, strengthen the governance of traffic violations, especially pedestrian and non motor vehicle traffic violations, and cultivate the habit of civilized travel of the general public.

Implement the mode of "integration of emotion, guidance, diligence, supervision and media", and set up 118 road lengths for 32 grid primary and secondary trunk roads in the main urban area. Implement the iron cavalry service, command and dispatch center to grasp the road conditions at any time, and improve work efficiency. Make comprehensive arrangement for unclear markings, nonstandard signs, weak signal lights and unreasonable guardrail setting, and improve various traffic facilities at intersections and sections in the main urban area. A new pedestrian crossing signal lamp is installed for the second crossing of pedestrians on the first line of Huai'an road to create a good road traffic environment. Through the exposure of LED screen, newspaper, TV and official blog at the intersection, the face recognition system is used to continuously capture and record illegal behaviors such as pedestrians not walking zebra crossing.Send a special person to the door for punishment according to the information of the offender; Actively promote the illegal "random shooting" activities of pedestrians and non motor vehicles. The general public can obtain relevant information by scanning the QR code of the Traffic Management Bureau of the Municipal Public Security Bureau, and appropriately reward those who have outstanding "random shooting" effects. We will continue to implement the incentive measures of "choosing one of the three, organizing forces to strictly manage and deal with pedestrian and non motor vehicle traffic violations at intersections. Otherwise, the license plate recognition system will not be able to work". If a non motor vehicle refuses to accept a fine for serious traffic violations, the non motor vehicle is detained on the spot; Tow away non motor vehicles illegally parked on the road section, especially in the fast lane or slow lane. We will strengthen the management of illegal electric vehicles, illegal assembly (modification) of electric vehicles, fuel tricycles, four wheeled vehicles and "street bombing electric motorcycles". Seizure of one vehicle; Strengthen the parking management of postal, express and takeout electric vehicles, and combine education with reward.Where the mobile camera cannot cover the area, the mobile camera shall be used to continuously capture and punish the illegally parked vehicles in key sections. Organize mounted police to patrol and tow away all motor vehicles parked in the fast lane. Severely crack down on private parking lots and scribbling parking lines, and implement time limited parking for free parking spaces; For sections with strong demand, continue to set aside temporary parking spaces for 3 minutes, 15 minutes and 1 hour; Actively solve the problem of parking in the old community, and set up tidal parking spaces around the community. When pedestrians and non motor vehicles are found passing, they shall slow down, stop and give way in advance; Pedestrians and non motor vehicles should walk through street facilities when crossing the street, and motor vehicles encounter the landmark of "car let people". The license plate recognition system should concentrate on crossing the zebra crossing and pass quickly in case of vehicles giving way.
