Cybercriminals can break into any connected system. Traditionally, IT systems with their many open interfaces had been in the focus of attackers, while embedded systems were perceived to be too difficult to hack and not worth the time and energy required. But as systems have added Ethernet, WLAN, USB, Bluetooth, GPS, and other connectivity features, the number of attack surfaces has increased. The most popular hacking method involves attacking a diagnosis port, or otherwise open interface, which can give a malevolent party access to functions or, at least, the ability to corrupt data and prohibit performance such as denial-of-service attacks.

网络犯罪分子可以闯入任何连接的系统。传统上，具有许多开放接口的 IT 系统一直是攻击者的焦点，而嵌入式系统被认为太难破解，不值得花费时间和精力。但随着系统添加了以太网、WLAN、USB、蓝牙、GPS 和其他连接功能，攻击面的数量也在增加。最流行的黑客方法涉及攻击诊断端口或其他开放接口，这可以让恶意方访问功能，或者至少可以破坏数据并禁止拒绝服务攻击等性能。
