WebAssembly (Wasm) has found its way outside the browser and has been widely adopted on the server side as in browsers with the development of WebAssembly System Interface (WASI).

API gateways support plugins compiled to Wasm from languages like Rust and Go, which extends the capability of their underlying proxies like Nginx or Envoy.

But how do these API gateways support these Wasm plugins? Do they have limitations? What will they look like in the future? In this “under the hood” talk, I will attempt to answer these questions and more.

XDA underwent a couple of major migrations during 2021-2022 that changed how the website and forums behaved. Among these major migrations, the old official client app namely "XDA" and "XDA Labs" was deprecated and a new webview-based app was released (also deprecated after one year). The API documentation was also removed with it.

This talk aims to share how a new unofficial client "ReLabs" was developed after reverse-engineering the new official client app (deprecated). ReLabs is built with the new Jetpack Compose, the old view system, and the Figma with Relay plugin. It also has working push notifications using Firebase and is completely open-source, unlike the official client.

On March 29, 2024, Andres Freund, a Microsoft software developer, emailed Openwall informing the community of the discovery of an SSH backdoor in XZ Utils 5.6.0 and 5.6.1 (CVE-2024-3094). XZ Utils is a suite of open-source software that provides developers with lossless compression. The tool is very widely distributed as it comes installed by default on most Linux distributions and macOS systems. In this talk, I will walk you through the complete story of how XZ Utils was found compromised and how the attacker slowly gained trust and finally launched his backdoor to the wild. I will also briefly talk about other popular supply chain attacks and what we can learn from all these stories.
