Topic: You’re Doing IoT RNG

Presenters: Dan Petro and Allan Cecil

Date: August 6, 2021 at 5 p.m. PST

Location: In Person (Track 1) and Virtual


Think of a random number between '0' and infinity. Was your number '0'? Seriously? Crap. Well unfortunately, the hardware random number generators (RNG) used by your favorite IoT devices to create encryption keys may not work much better than you when it comes to randomness. In this talk, we'll delve into murky design specs, opaque software libraries, and lots of empirical results. We wrote code for many popular IoT SoC platforms to extract gigabytes of data from their hardware RNGs and analyze them. What we found was a systemic minefield of vulnerabilities in almost every platform that could undermine IoT security. Something needs to change in how the Internet of Things does RNG. The vulnerabilities are widespread and the attacks are practical. RNG is bad out there - "IoT Crypto-pocalypse" bad.

Topic: ATM Transaction Reversal Frauds (And How To Fight Them)

Presenter: Hector Cuevas Cruz

Date: August 6, 2021

Time: 10 a.m. PST

Location: DEF CON Payment Village - Virtual


Transaction Reversal Frauds (TRF) are a type of attack that doesn't require malware, complex physical attacks, or even opening an ATM. Instead they abuse some business and operational rules defined by the financial institutions to cash-out an ATM. This presentation describes what Transaction Reversal Frauds are, why this type of attacks are on rise, and more importantly, how to detect them through an integral analysis of journaling and some other logs.
