Protecting your phone verification flow from fraud & abuse
Authenticate 2022 - SMS pumping prevention
Preventing phone verification fraud (SMS pumping)
In the last year we've seen a new type of fraud become more common where fraudsters attack phone verification forms with thousands of requests. This type of attack, known as SMS pumping, causes inflated traffic to your app with the intent to make money and not to steal information. Unfortunately this means you might be hit with higher than expected bills from your telecom provider if your application isn't designed to prevent it.
This talk will describe SMS pumping in more detail, including how it compares to similar attacks like IRSF and how fraudsters profit from this tactic. You'll learn strategies to prevent the attack and improve your phone verification workflow in the process, ensuring all of the benefits of phone number verification without unintended expenses.
Auth on the web: better authentication
New technology is challenging the premise that we have to choose between more friction or more security for authenticating users. This talk explores the benefits and drawbacks of frictionless authentication options beyond traditional one-time passcodes like biometrics, contextual data, or using devices as secure keys.
WebAuthn
Authentication is a sneaky problem - the most secure options don't usually have widespread adoption, especially among consumer applications. But what if we could fix that? Narrator: we can. WebAuthn is a somewhat new authentication standard that uses our everyday devices like phones and computers and turns them into phishing-resistant security keys. It almost sounds too good to be true. This talk will dig into how the technology works, when you can and should use it, and how to get started. We'll dig into why this isn't widely adopted yet and if or when we can expect it to be. You'll walk away with a better understanding of a new authentication channel and possibly some hope for a more secure future.
2FA in 2020 and Beyond
Security professionals agree: SMS based Two-factor Authentication (2FA) is insecure, yet thousands of companies still employ this method to secure their customer-facing applications. This talk will look at the evolution of authentication and provide a data-driven analysis of the tradeoffs between the different types of factors available.
Identiverse 2020 - Account Recovery with 2FA
You've built login for your application—and even added 2FA—but what happens when a customer upgrades their phone, loses their device, or otherwise gets locked out of their account? This session will show how to accommodate account recovery when the user has 2FA enabled while minimizing account takeover and support overhead.

Introduction to SHAKEN/STIR
This talk will discuss the latest advancements with STIR (Secure Telephone Identity Revisited) and SHAKEN (Signature-based Handling of Asserted information using toKENs), new tech standards that use well accepted public key cryptography methods to validate caller identification. We’ll discuss the path and challenges to getting this implemented industry wide, where this tech will fall short, and what we can do to limit exposure to call spam and fraud in the meantime.

Contact Center Authentication
You've built login for your application—maybe you even have 2FA—but what happens when a customer calls the support number listed on your website or product?
Security teams and app developers have thought a lot about online authentication, but we haven't applied the same rigor to designing systems for authenticating over the phone. At Twilio, product and engineering teams have spent the last year thinking about this problem and how to make the experience better for both the customer and the call center agent. In that time, I've called dozens of contact centers to learn about how everyone from startups to Fortune 50 companies attempt to identify and authenticate the end user. This talk will take a look at that research and outline best practices you can use in your own call centers. You'll leave the session understanding what information should be made available to the agent and what kind of product features you can build into your web or mobile application that can facilitate phone authentication.
Authentication Beyond SMS
Passwords get pwned. SMS 2FA gets compromised. We spend time clicking stop signs just to convince computers we're human. All of this in an attempt to identify a user we will probably never personally know. It's a fascinating challenge and we're up to the task!
This talk will walk through new channels for identity management beyond email and SMS. Encrypted messaging apps like WhatsApp broaden our options for delivering tokens and secure communications but lack the seamless user experience of Push Authentication or the offline benefits of TOTP. We'll dive into the tradeoffs for these approaches and help you choose the approach that will best protect you and your customers from signup to account recovery.

Hierarchical Digital Twin of a Naval Power System
A hierarchical digital twin of a Naval DC power system has been developed and experimentally verified. Similar to other state-of-the-art digital twins, this technology creates a digital replica of the physical system executed in real-time or faster, which can modify hardware controls. However, its advantage stems from distributing computational efforts by utilizing a hierarchical structure composed of lower-level digital twin blocks and a higher-level system digital twin. Each digital twin block is associated with a physical subsystem of the hardware and communicates with a singular system digital twin, which creates a system-level response. By extracting information from each level of the hierarchy, power system controls of the hardware were reconfigured autonomously. This hierarchical digital twin development offers several advantages over other digital twins, particularly in the field of naval power systems. The hierarchical structure allows for greater computational efficiency and scalability while the ability to autonomously reconfigure hardware controls offers increased flexibility and responsiveness. The hierarchical decomposition and models utilized were well aligned with the physical twin, as indicated by the maximum deviations between the developed digital twin hierarchy and the hardware.

The proper function of the integrated circuit (IC) in an inhibiting electromagnetic environment has always been a serious concern throughout the decades of revolution in the world of electronics, from disjunct devices to today’s integrated circuit technology, where billions of transistors are combined on a single chip. The automotive industry and smart vehicles in particular, are confronting design issues such as being prone to electromagnetic interference (EMI). Electronic control devices calculate incorrect outputs because of EMI and sensors give misleading values which can prove fatal in case of automotives. In this paper, the authors have non exhaustively tried to review research work concerned with the investigation of EMI in ICs and prediction of this EMI using various modelling methodologies and measurement setups.

Harnessing WebAssembly for Real-time Stateless Streaming Pipelines
Traditionally, dealing with real-time data pipelines has involved significant overhead, even for straightforward tasks like data transformation or masking. However, in this talk, we’ll venture into the dynamic realm of WebAssembly (WASM) and discover how it can revolutionize the creation of stateless streaming pipelines within a Kafka (Redpanda) broker. These pipelines are adept at managing low-latency, high-data-volume scenarios.
