Impact Analysis of Crypto Miner Malware Attacks Using Android Debug Bridge (ADB) Vulnerabilities via TCP/IP on Android-Based Raspberry Pi 4 IoT Device

Crypto-jacking attacks on IoT devices increase by 22% in 2021 compared to those in 2020. Crypto-jacking attacks using crypto miner malware were sent to the IoT devices via Android Debug Bridge (ADB) port, where the IoT devices such as smart TVs, phones, IP cameras and others running the Android operating system that ADB port was open. This study was made to find out how the attack workflow occurs and the possible impact on the device if it is exposed to the attack. The research was conducted by simulating Crypto-jacking Malware crypto-miner attacks using vulnerabilities in ADB via TPC/IP and then analyzing the impact of malware on devices using the hybrid analysis method. It was revealed that the malware used a lot of computing resources as seen from the CPU Clock Speed increasing up to eight times compared to when the malware was not running. The CPU Utilization Presentation also saw an increase when the malware was running, and the CPU computing resource usage increased up to 100
^%
. In addition, the device temperature also experienced a significant trend of increasing, up to more than 24°C when the malware started running. Meanwhile, the memory usage did increase but not significantly and did not have much effect on the device.
