X Launches XChat Beta: Elon Musk’s Bold New Messaging Platform with Encryption and Disappearing Messages

Elon Musk has introduced XChat, a new messaging platform currently in beta testing for select users, primarily those subscribed to X's paid service. XChat aims to enhance user interaction on X (formerly Twitter) and includes features such as group chats, end-to-end encryption, disappearing messages, file sharing, an option to leave messages unread, and a four-digit passcode lock. The launch of XChat coincides with the suspension of a previous encrypted direct messaging service that failed to gain traction. XChat represents a strategic shift towards a more sophisticated messaging framework, aligning with Musk's vision of creating an 'everything app' that integrates social media with secure communication. The success of XChat will depend on user adoption and its integration with existing platform functionalities.

Connect Amazon Bedrock Agents with Amazon Aurora PostgreSQL using Amazon RDS Data API

Generative AI applications are being integrated with relational databases, allowing organizations to utilize structured data for training AI models. This integration involves using the RDS Data API with Amazon Aurora PostgreSQL-Compatible Edition and Amazon Bedrock for AI model access and automation. The solution enables natural language queries to be converted into SQL statements, executed against the database, and returns results in a user-friendly format. The architecture includes several steps: invoking the Amazon Bedrock agent with natural language input, generating SQL queries using large language models (LLMs), executing those queries via the Data API, and returning formatted results. Security measures are in place to restrict operations to read-only, preventing modifications that could compromise data integrity. To implement this solution, prerequisites include deploying an Aurora PostgreSQL cluster using AWS CDK and setting up the necessary Lambda functions and IAM roles. The agent is designed to convert natural language prompts into SQL queries and execute them securely. Testing can be conducted through the Amazon Bedrock console or the InvokeAgent API, with options for tracing the agent's steps. Key considerations for this integration include limiting it to read-only workloads, implementing parameter validation to prevent SQL injection, and ensuring comprehensive logging and auditing. For multi-tenant applications, appropriate isolation controls should be established. To avoid future charges, all resources created through CDK should be deleted after use.

Waltz’s Use of Messaging Platform Raises New Security Questions

Michael Waltz, the former national security adviser, mistakenly included a journalist in a sensitive chat on Signal during a cabinet meeting, raising concerns about communication practices among senior officials. A photograph captured him using a different messaging app that promotes archiving for record-keeping, which raises compliance questions with federal regulations. Visible contacts on his screen included Vice President JD Vance, special envoy Steve Witkoff, Secretary of State Marco Rubio, and Director of National Intelligence Tulsi Gabbard. The use of encrypted messaging apps like Signal complicates the National Archives' role in preserving governmental records, highlighting the tension between secure communication and the need for transparency in government operations.

Caught on camera: Mike Waltz using less secure version of Signal messaging app – The Times of India

Mike Waltz has come under scrutiny due to a photograph showing his use of a modified messaging application, TM SGNL, raising security concerns. The photo, taken by Reuters on April 30, 2025, during a White House cabinet meeting, revealed Waltz's phone screen with conversations involving JD Vance, Marco Rubio, Tulsi Gabbard, and Steve Witkoff, who are key figures in foreign relations and national security regarding Ukraine. TM SGNL is a variant of Signal, known for its encryption, but its archiving feature risks compromising end-to-end encryption. Messages displayed included a note to Rubio stating, "there is time," and Vance's message about confirmation from a counterpart. Following these events, President Trump appointed Waltz as UN ambassador and Rubio as interim national security advisor. The White House stated that "Signal is an approved app for government use and is loaded on government phones."

Signal App reveals need for more secure channels

Mike Waltz, national security adviser under President Trump, accidentally included Jeffrey Goldberg, editor-in-chief of The Atlantic, in a confidential military chat on Signal that involved senior officials discussing imminent U.S. military strikes on Yemen. This incident raised concerns about the administration's secure communication practices, particularly as it involved sensitive military strategies. Despite Signal's encryption, critics argue that public group chats should not be used for classified discussions, highlighting vulnerabilities in communication protocols. Secure rooms are designed for classified discussions with strict protocols, which were not followed in this case.

Signal, Telegram or WhatsApp: Which Encrypted Messaging App Should You Choose

Telegram, a cloud-based messaging platform, stores necessary operational data, including metadata such as IP addresses. In 2024, Telegram updated its privacy policy to comply with law enforcement requests for user data with valid legal documentation, leading to the fulfillment of 900 requests from U.S. authorities affecting 2,253 individuals. The platform has experienced data breaches, including a 2020 incident exposing data from approximately 42 million Iranian users and a 2019 vulnerability that allowed Chinese agencies to identify protestors in Hong Kong. Telegram features public channels without end-to-end encryption and offers secret chats with end-to-end encryption, limited to the device of origin. Automatic message deletion is available with a minimum interval of one day. While the client applications are open-source, the server-side code is closed-source, requiring user trust in the company to protect data. Metadata collection continues despite end-to-end encryption. Telegram operates on a freemium model, with basic features available for free and a paid tier for additional functionalities. The app is available for download on the Apple App Store and Google Play Store at no charge.
