Facial Recognition Security Research
IOActive, Inc. (IOActive) has conducted extensive research and testing of facial recognition systems on commercial mobile devices. Our testing lab includes testing setups for 2D- and 3D-based algorithms, including technologies using stereo IR cameras. For each of the different technologies, we first try to understand the underlying algorithms and then come up with creative and innovative setups to bypass them. Once an unlock is achieved, we calculate the Spoof Acceptance Rate (SAR), as described in the Measuring Biometric Unlock Security” section of the Android Compatibility Definition Document.1 This metric allows…
How we hacked your billion-dollar company for forty-two bucks
subvert (v) : 3. To cause to serve a purpose other than the original or established one; commandeer or redirect: – freedictionary.com Why did one straw break the camel’s back?Here’s the secretThe million other straws underneath it– Mos Def, Mathematics The basic idea of this blog post is that 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…
Cracking the Snapcode
A Brief Introduction to Barcodes Barcodes are used everywhere: trains, planes, passports, post offices… you name it. And just as numerous as their applications are the systems themselves. Everybody’s seen a UPC barcode like this one: [1] But what about one like this on a package from UPS? [2] This is a MaxiCode matrix, and though it looks quite different from the UPC barcode, it turns out that these systems use many common techniques for storing and reading data. Both consist of…
The Risk of Cross-Domain Sharing with Google Cloud’s IAM Policies | Chris Cuevas and Erik Gomez, SADA
We all recognize the importance of the DRS Organization Policy within a GCP Org, now we’d like to discuss Cross-Domain Sharing, or XDS as we are calling it. Do you know where your organization’s identities are being used externally? If not, we want to share details on the risks and how SADA can help assess your GCP org.
Counterproliferation: Doing Our Part
IOActive’s mission is to make the world a safer and more secure place. In the past, we’ve worked to innovate in the responsible disclosure process.
Breaking Protocol (Buffers): Reverse Engineering gRPC Binaries
The Basics 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…
Techspective Podcast – The Value of Red and Purple Team Engagements
Episode 070. Tony Bradley of Techspective, chats with John Sawyer, IOActive Director of Services, Red Team, on the wide-ranging effects of alert fatigue, COVID-19 pandemic, physical security and more – directly affecting cybersecurity resiliency and the efficacy/benefits of red/purple team and pen-testing services.

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…
