Black Hat USA 2014: Think Hard

Code can always change, but silicon is forever... more or less. Today's quartet of Black Hat Briefing highlights, which will all take place at Black Hat USA 2014, examine security with a focus on the hard stuff.

It's always fun when a solution for one issue can be repurposed to solve another problem. Creating a Spider Goat: Using Transactional Memory Support for Security brings us another example, in which the presenters bent the Transactional Synchronization Extension (TSX) memory conflict avoidance features of modern Intel CPUs toward security purposes. Used this way, TSX can detect malicious RAM modifications with minimal overhead. They'll also address potential problems of this unofficial use case.

The last decade's seen great advances in secure software development practices, but secure hardware development remains essentially undefined. Most hardware doesn't bother with security routines, or it keeps them obfuscated and secretive. SecSi Product Development: Techniques for Ensuring Secure Silicon Applied to Open-Source Verilog Projects aims to get that ball rolling, documenting pre- and post-silicon validation techniques and applying them to various open-source core designs while classifying various hardware security bugs into several categories.

The Bluetooth-, IR-based Super iBox BT, popular among real estate professionals, is a physically hardened device that stores a door key and contains a hardened MSP430 with a blown JTAG fuse. Is this still a large obstacle? In Reverse-Engineering the Supra iBox: Exploitation of a Hardened MSP430-Based Device, Braden Thomas will present his findings, giving an update on Goodspeed's 2008 bootstrap attacks and ultimately demonstrating how to perform firmware extraction reliably on such boxes. His newly developed attack can open any iBox, despite their complex and surprisingly effective crypto key management scheme.

Speaking of keys, How to Wear Your Password will present a new authentication paradigm that achieves both a desirable user experience and a high level of security. The security bracelet in question has a low-power processor, a Bluetooth LE transmitter, an accelerometer, and a clasp that detects wearer presence or lack thereof. Expect a thorough case study, complete with discussion of the physical design, the lightweight security protocols needed for pairing, determination of user intent, credential management, safeguards against violent attacks on the wearer, and the security implications of the design.

Regular registration ends on July 26. Please visit Black Hat USA 2014's registration page to get started.

Enterprises today have a wide range of third-party options to help improve their defenses, including MSSPs, auditing and penetration testing, and DDoS protection. But are there situations in which a service provider might actually increase risk?

CVE-2012-2808
Published: 2015-04-01
The PRNG implementation in the DNS resolver in Bionic in Android before 4.1.1 incorrectly uses time and PID information during the generation of random numbers for query ID values and UDP source ports, which makes it easier for remote attackers to spoof DNS responses by guessing these numbers, a rel...

CVE-2014-9713
Published: 2015-04-01
The default slapd configuration in the Debian openldap package 2.4.23-3 through 2.4.39-1.1 allows remote authenticated users to modify the user's permissions and other user attributes via unspecified vectors.

CVE-2015-0259
Published: 2015-04-01
OpenStack Compute (Nova) before 2014.1.4, 2014.2.x before 2014.2.3, and kilo before kilo-3 does not validate the origin of websocket requests, which allows remote attackers to hijack the authentication of users for access to consoles via a crafted webpage.

CVE-2015-0800
Published: 2015-04-01
The PRNG implementation in the DNS resolver in Mozilla Firefox (aka Fennec) before 37.0 on Android does not properly generate random numbers for query ID values and UDP source ports, which makes it easier for remote attackers to spoof DNS responses by guessing these numbers, a related issue to CVE-2...

CVE-2015-0801
Published: 2015-04-01
Mozilla Firefox before 37.0, Firefox ESR 31.x before 31.6, and Thunderbird before 31.6 allow remote attackers to bypass the Same Origin Policy and execute arbitrary JavaScript code with chrome privileges via vectors involving anchor navigation, a similar issue to CVE-2015-0818.
