We conduct advanced penetration tests of IoT hardware, focusing on the communication protocols UART (Universal Asynchronous Receiver and Transmitter) and I2C (Inter-Integrated Circuit) in integrated circuits.

We check the control of individual bits, analyze open ports, and test the reaction of devices to unauthorized signals.

In addition, we perform tests for open ports, receiving unauthorized signals, and sampling to assess potential threats and secure IoT device communication against attacks.

We test firmware in a simulated environment and directly on devices, saving it in EEPROM devices and FLASH memory.

We perform memory dumps and analyze the contents of buffers. We reverse engineer, evaluate the source code and vulnerabilities, and test firmware modifications.

In addition, we verify the permissions of the MQTT (Message Queuing Telemetry Transport) protocol, which allows us to analyze and modify permissions to increase security.

We conduct radio transmission analysis, focusing on intercepting and investigating protocols such as BLE (Bluetooth Low Energy), Zigbee (IEEE 802.15.4), LoRa (Low Power, Wide Area), and 6LoWPAN (IPv6 Low-Power Wireless Personal Area Networks).

Our tests aim to detect security vulnerabilities and ensure security in wireless communication.
