Hacking IoT devices by chaining application security vulnerabilities - Rick Ramgattie (BSides Tampa 2019) (Hacking Illustrated Series InfoSec Tutorial Videos)

Hacking IoT devices by chaining application security vulnerabilities
Rick Ramgattie
BSides Tampa 2019

Abstract: Fully comprising an embedded device isn,t always as easy as sending a GET request with admin=true. Sometimes, owning an embedded device takes multiple different vulnerabilities, creativity, and a little finesse. In this live demo, we show how we were able to chain multiple vulnerabilities in the Lenovo ix4-300d network attached storage (NAS) device into a remote exploit that can be executed with little user interaction. As a result, an adversary can provide the victim with a link to a malicious page that grants the attacker the ability to extract all information stored on the victim,s NAS, and the ability to execute arbitrary operating system (OS) commands on the compromised NAS. In the talk we cover how we first identified command injection, then used cross-site scripting (XSS) and cross-site request forgery (CSRF) to build an exploit that would hijack values stored in the victim,s browser storage, issue a malicious request on the user,s behalf, and issue an OS command to open a remotely accessible operating system shell.

Bio: Rick Ramgattie is a Security Analyst at Independent Security Evaluators (ISE), where he conducts high-end, custom security assessments of computer hardware, software products, and manages a team of security researchers. Rick recognizes that it isn't all that easy to get into the information security community and enjoys being part of a growing community. Now, as someone who appreciates the art of reverse engineering, he has taken part in hands-on security assessments of complex systems, IoT devices, and many different native and mobile applications. Rick enjoys cryptography, reverse engineering, and reading.
