So instead of taking over the computer, you just have it trash itself?
It would be messy for sure. No software to run.
Jeez.

He’ll also unveil a fuzzing tool he developed that can be used to launch such an attack as well as to detect PDOS vulnerabilities in firmware systems.

<FONT>The danger with embedded devices is that they are often forgotten. They don’t always get patched or audited, and they can contain application-level vulnerabilities, such as flaws in the remote management interface that leave the door open for an attacker, according to Smith. And remote firmware updates aren’t typically secured, but rather set up to occur by default.
