How We Hacked Your Billion-dollar Company for Forty-two Bucks
Jamie Riden, IOActive Security Consultant/CREST-CHECK Lead, explores the weaknesses in outward-facing services most enterprises employ. Most organizations’ Internet perimeters are permeable. Weaknesses in outward-facing services are rarely independent of one another, and leveraging several together can often result in some sort of user-level access to internal systems. A lot of traffic goes in and out of a normal company’s Internet perimeter: email comes in and goes out, web traffic from customers or potential customers comes in, web traffic for internal users goes out, and lots of necessary services create traffic,…
Cracking the Snapcode
Daniel Moder, IOActive Security Consultant, explores the world of the ever-increasing forms of bar codes, specifically, cracking Snapcodes. Snapcode is a proprietary 2D barcode system that can trigger a variety of actions when scanned in the Snapchat app. Unlike some bar code systems, there is no public documentation about how the Snapcode system works. Daniel delves in to discover the inner workings of Snapcode to answer the following questions: What data do Snapcodes encode? How do Snapcodes encode data? What actions can be triggered when these codes are scanned?

Breaking Protocol (Buffers): Reverse Engineering gRPC Binaries
gRPC is an open-source RPC framework from Google which leverages automatic code generation to allow easy integration to a number of languages. Architecturally, it follows the standard seen in many other RPC frameworks: services are defined which determine the available RPCs. It uses HTTP version 2 as its transport, and supports plain HTTP as well as HTTPS for secure communication. Services and messages, which act as the structures passed to and returned by defined RPCs, are defined as protocol buffers. Protocol buffers are a common serialization solution, also designed by…

Cybersecurity Alert Fatigue: Why It Happens, Why It Sucks, and What We Can Do About It | Andrew Morris, GreyNoise
Alarm fatigue or alert fatigue occurs when one is exposed to a large number of frequent alarms (alerts) and consequently becomes desensitized to them. Desensitization can lead to longer response times or missing important alarms.
Cross-Platform Feature Comparison
For an Intel-commissioned study, IOActive compared security-related technologies from both the 11th Gen Intel Core vPro mobile processors and the AMD Ryzen PRO 4000 series mobile processors, as well as highlights from current academic research where applicable. Our comparison was based on a set of objectives bundled into five categories: Below the OS, Platform Update, Trusted Execution, Advanced Threat Protection, and Crypto Extension. Based on IOActive research, we conclude that AMD offers no corresponding technologies those categories while Intel offers features; Intel and AMD have equivalent capabilities in the Trusted…
