The motivation of hackers sometimes can be plain as day. Other times, not so much.
As attacks on Internet of Things (IoT) devices and deployments escalate, it is important to understand what these attackers are trying to accomplish. Understanding these motives, after all, can help us to pinpoint why a security vulnerability represents a risk, to prioritize mitigation and defenses, and to focus responses to attacks.

The Yocto Project is well known for enabling product developers to quickly and easily customize Linux for Internet of Things (IoT) devices and other embedded systems. But today’s environment is marked by heightened security concerns, skyrocketing vulnerability reports, and high-profile security breaches.
Getting your embedded system product to market fast is important. But getting to market fast without a secure design and a plan for managing future vulnerabilities is a huge mistake. If you design, build and support products with embedded Linux using Yocto, it’s important to evaluate security of your system from the point of view of the end customer who will deploy it.

A classic security breach vector involves exploiting weak authentication. As security researchers like to point out, failing to change default passwords for administrative access remains the top security issue for all types of IT systems.
But a related — and perhaps more devious — attack vector involves exploiting a weakness in a process that is supposed to help ensure device security in the first place: the remote system update.
