A fully functioning Raspberry Pi often costs between $ 50 to $100, and sometimes less. Because of its open-source nature, the source code could be analyzed by malicious actors and allow for targeted attacks. In April 2018, a hacker broke into NASA’s network and stole 500 Mb of data about the ongoing Mars mission. Using the so-called “shadow IoT,” cybercriminals hijack devices such as the Raspberry Pi and use them to host malware that in turn performs DDoS attacks.
