Black Hat: System Firmware Attack and Defense for the Enterprise

A variety of attacks targeting system firmware have been discussed publicly, drawing attention to interaction with system firmware components. This includes operating system loaders, secure boot mechanisms, runtime interfaces, and system management mode (SMM). This training will detail and organize objectives, attack vectors, vulnerabilities, and protection mechanisms in this fascinating environment. The training includes two parts.
1. Present a structured approach to system firmware security analysis and mitigations through lecture and hands-on exercises to test system firmware for vulnerabilities. After the training, students will have basic understanding of platform hardware components, system firmware components, attacks against system firmware, and available mitigations. Students can apply this knowledge to identify firmware vulnerabilities and perform forensic analysis.
2. Apply concepts to an enterprise environment. Using an understanding of security issues, students explore potential risks to operational environments including both supply chain and remote malware attacks. Students will perform assessments and basic forensic analysis of potential firmware attacks.

Yuriy working on new CHIPSEC Spectre test

Nice to see some recent CHIPSEC activity, given all the recent related CVEs…
…But this is not from the CHIPSEC team, it is from ex-CHIPSEC team member Yuriy of Eclypsium.

Added new module checking for Spectre variant 2
The module checks if system is affected by Speculative Execution Side Channel vulnerabilities. Specifically, the module verifies that the system supports hardware mitigations for Branch Target Injection a.k.a. Spectre Variant 2 (CVE-2017-5715)

See source comments for more info.

CHIPSEC for ARM: to be released at Black Hat

I nearly missed this CHIPSEC announcement in the below Black Hat abstract. Exciting.

Blue Pill for Your Phone
By Oleksandr Bazhaniuk & Yuriy Bulygin

In this research, we’ve explored attack surface of hypervisors and TrustZone monitor in modern ARM based phones, using Google Nexus 5X, Nexus 6P, and Pixel as primary targets. We will explain different attack scenarios using SMC and other interfaces, as well as interaction methods between TrustZone and hypervisor privilege levels. We will explore attack vectors which could allow malicious operating system (EL1) level to escalate privileges to hypervisor (EL2) level and potentially install virtualization rootkit in the hypervisor. We will also explore attack vectors through SMC and other low level interfaces, interactions between TrustZone and hypervisor (EL2) privilege levels. To help with further low level ARM security research, we will release ARM support for CHIPSEC framework and new modules to test issues in ARM based hypervisors and TrustZone implementations, including SMC fuzzer.
