Recently, I discovered a campaign spreading via Telegram Mini Apps. In fact, a threat actor attempted to phish me using this tactic.👇 The technique is highly convincing because it involves a trust boundary violation in Telegram’s MiniApp SDK (affecting Android, Desktop, iOS, and Web versions). Telegram allows third-party code...

Is reverse proxy phishing slowly dying? 💀🎣 This is what I've been trying to find out during the past several months. Major websites have caught up and vastly improved their security, successfully detecting malicious traffic originating from reverse-proxy phishing servers. The attackers have changed their tactics and begun utilising a new method that involves using a real web browser to sign in on the phished user's behalf. In the video I've just released, I am demonstrating a live demo of a modern phishing attack using the Credential Relay Phishing technique, which evades all current anti-phishing measures deployed against reverse-proxy phishing. To simulate a phishing attack against a Google account secured with FIDO MFA, I am using the latest features of Evilginx Pro to downgrade the FIDO MFA to less secure & phishable MFA alternatives. Additionally, the attack simulation employs a Browser-in-the-Browser social engineering technique to spoof the phishing URL in the address bar of the fake pop-up window, displaying the sign-in page. Everything you see in the video is ready to use in the latest beta version of Evilginx Pro, available exclusively to vetted cybersecurity professionals working within cybersecurity companies or internal red teams. Evilginx Pro's latest features include: Phishlets 2.0: A complete rewrite of the old phishlets format now allows for modification of every part of HTTP traffic going through the reverse proxy server. The new format allows hosting of static website content utilising external modules such as Evilpuppet to simulate Credential Relay Phishing attacks. Downgrading FIDO MFA: With the most recent implementation of Evilpuppet, it is now possible to control a separate background browser session and sign in on behalf of the phished user, allowing the attacker to be the one responsible for choosing which MFA method the user should authenticate with. Browser-in-the-Browser: It is now possible to embed any phishing page within a fake browser pop-up window, rendered with JavaScript and stylised for the OS on which the page is displayed. This enables the construction of extremely convincing social engineering attacks, as the URL in the pop-up window can be spoofed to any value using legitimate hostnames. If you want to use these features in your next red team engagement or assess your company's readiness against modern phishing attacks, make sure to give Evilginx Pro a try. Hope you enjoy the video! 💗 Happy phishing! 🪝🐟 Kuba

Anthropic's most viral feature is now open-source! Until now, Anthropic's Generative UI capabilities only existed inside its own products. CopilotKit🪁 just shipped Open Generative UI, an open-source implementation of Claude Artifacts that works in any app. The agent generates HTML/SVG at runtime, and CopilotKit streams it token-by-token into a sandboxed iframe inside the app's chat. So the user can watch the UI assemble itself in real time, not after the full response is ready. The sandbox is fully isolated with no access to the parent app, the DOM, or user data. So if the agent hallucinates broken markup or unexpected JavaScript, nothing leaks outside the iframe. Under the hood, the agent does not select from pre-built components. Instead, it generates arbitrary visuals from scratch every time. The output is unconstrained by default, but you can shape it by defining prompt-based skills that teach the agent specific visual formats or guidelines. For instance, a skill prompt can guide the agent toward producing a Chart.js dashboard with proper axis labels and responsive sizing, or an interactive 3D model with rotation controls. The video below shows this in action, and the output quality you see actually comes from the skills layer. Open Generative UI runs on AG-UI, so it works out of the box with LangGraph, CrewAI, Mastra, Google ADK, AWS Strands, and more. It also ships with a standalone MCP server that plugs into Claude Code, Cursor, or any MCP-compatible client. And the entire stack is built on top of CopilotKit, the open-source frontend framework for agents and generative UI. 30k+ GitHub stars, with SDKs for React, Next.js, Angular, and Vue. I have shared the GitHub repo and a live playground in the replies!

Anthropic's in trouble, again! They spent years building what's now fully open-source. What made Claude feel different from a normal app is that the agent could act inside the interface instead of only talking in a chat box. For instance, Claude Artifacts let an agent render real UI, charts, dashboards, and interactive components that assemble live inside the response. Every major AI product tried to replicate it. But the problem was that unlike reasoning, planning, tool-calling, etc., none of it shipped natively with LangGraph, CrewAI, or Google ADK. So teams started building an owned version that required engineering the entire interface layer from scratch. Most teams, however, just settled for shipping the agent as a backend API in a chat box since rendering the UI is only one piece of it. To actually make it work, the interface layer also needed real-time streaming, state kept in sync between agent and UI, conversations that persist across sessions, and reconnection when a user refreshes mid-run. CopilotKit🪁 is now the only open-source framework that actually lets you build your own full-stack Claude-like apps. It decouples the agent from the interface, talking over AG-UI (an open protocol for agent-to-user communication). Being a standard protocol, the frontend never needs to know whether it is talking to a LangGraph or a CrewAI agent. You can change the backend anytime and the UI will never notice. In practice, CopilotKit's interface layer gives several pre-implemented React building blocks that wire the agent directly into the app, like: - generative UI, so the agent renders real components instead of text - chat windows, sidebars, and popups, or a fully headless setup - shared state, so the agent and app stay in sync - human-in-the-loop approvals, where the agent waits before acting - persistent threads that store the whole session, including the agent-user interactions and generated UI, not just text And because that full history is captured, those interactions can feed a self-learning layer that also improves the agent from real usage over time. The interface layer that Anthropic spent years engineering in-house is now literally available to any developer/team. CopilotKit is open-source with 30k+ GitHub stars, and AG-UI, the protocol underneath, is already supported across every major agent framework: LangGraph, CrewAI, Mastra, Google ADK, and more. CopilotKit GitHub repo → (don't forget to star it ⭐ ) If you want to go deeper, I found a detailed breakdown by Shubham Saboo recently on the three Generative UI patterns, with implementation. Read it below.

AG-UI makes building agentic applications dramatically easier. Here's how it works. This is a model for a simple chatbot: User → LLM → Response But interactive agents that render UI, pause for approvals, and ask users for input need a much more complex model. When building these agents, a response from the LLM will include a series of state changes as the agent runs: • Agent started a task • Agent called a tool • Agent updated its state • Agent streams these tokens • Agent is waiting on a human • Agent is resuming the task The Agent-User Interaction Protocol (AG-UI) treats the LLM response as a stream of events rather than a text endpoint. In practice, here is what you get as an agent runs: 1. Lifecycle events so your UI knows where the agent is. 2. Text messages that stream tokens. 3. Tool calls so your UI can prefill a form with any required arguments. 4. State updates that keep your UI in sync with the agent. 5. Special events for human approvals, rich media, and custom needs. All of these events travel over standard transports (SSE, WebSockets, or plain HTTP) as JSON. As a result, you can build a frontend that stays in sync with the agent's progress without having to invent a custom process to make this happen. For example, building a human-in-the-loop workflow becomes an off-the-shelf component you can integrate rather than build from scratch. CopilotKit🪁 is the creator of AG-UI, and you can use it when building frontend applications pretty much anywhere: • React • Angular • Vue • React Native • Slack • Teams • Discord • WhatsApp • Telegram Here is the link for you to check it out: Thanks to the CopilotKit team for partnering with me on this post.

A little look behind the scenes: Many of you asked how I handle switching from SwiftData & CloudKit to Firebase and a different way of sharing entries with your friends. Previously, there was no need to create an account and the app just used the user's iCloud ID in the background to "sign up". Why did I do this? SwiftData is really nice to use but after working with it for over a year now, it feels still quite unstable, buggy and errors are super hard to track. Same goes for CloudKit and the CloudKit sharing that I implemented. For a growing app, in my opinion, it's just not feasible to use because errors happen regularly, you don't really know if the data is stored (and shared) correctly and the documentation on CK is just bad. I have big plans for this app (reacting to your friends' entries, Apple Health integration, tagging multiple friends in entries etc.) and all of it is now much simpler - and faster to build. The Migration part When an existing user starts the app, a little migration sheet with a couple of steps opens which can't be dismissed. The goal is that the user maintains all entries and can use the app like before :) Steps: 1) Create an Account using Apple Sign In and Firebase Auth 2) Migrate your user profile (profile picture etc.) and all your friends from SwiftData to Firestore. Here I basically iterate over all the data that is there, run a custom conversion for all the fields (some things need to be stored differently) and save them. Profile Images are now saved in Firebase Storage 3) Migrate all entries to Firestore the same way. Images and Voice Notes are now saved in Firebase Storage (that might take a bit of time, video is sped up) 4) After that, migration is basically done and the user can use the app like before. In the settings, the user can now log out or delete the account, things that weren't possible before. If for any reason the migration has to be done again, this can be triggered from the settings as well. How do I decide if a user needs to migrate? Previously, I saved the user's profile in SwiftData under a specific key (simplified). If the app finds something under this key, user is prompted for a migration. New users don't have to run through the migration. They simply start fresh with the Apple Sign in in the onboarding like seen in the referenced post. How does sharing entries now work? For sharing, I create deeplinks using branch . io now. These links basically work like every other Invite Link you've received or created. The friend opens the link, can accept your invitation and now both of you are connected as buddies. Previously using CloudKit Sharing, this process took two steps - each user had to share a link to give access to their entries. The process now is much simpler and better understand for the user. Developing the migration Tbh I thought this would be way quicker. In the end it was > 100 commits since I had to basically change every screen in the app. Working with SwiftData is quite different to how things work with Firebase (and most other frameworks), so every interaction where data was involved had to be reworked. Now the app runs on a combination of Firestore, Cloud Functions and Firebase Storage. In terms of memory, the app feels notably faster and only needs around 1/4 of the memory bandwidth it needed before. Let's see if it will be worth it! All in all super happy with the new flexibility for the app and not being limited by the technology anymore 👀
