Elon Musk’s XChat App Is More Like Facebook’s Messenger Than Signal

Elon Musk launched the XChat app, a stand-alone messaging service for X users, claiming it to be the only secure, encrypted messaging app. Critics have raised concerns about XChat's security, particularly its requirement to link an existing X account and the storage of cryptographic keys on X's servers. The app's rollout faced delays and confusion, with users in the UK experiencing access issues. Initial user experiences indicated limited messaging capabilities, as many contacts may not have X accounts. The app's privacy claims were questioned, as it still collects data linked to users. XChat shares similarities with Facebook's Messenger, both requiring account creation and linking to their respective platforms.

Using Windows or Microsoft Office? India issues high-severity cyber alert, how to stay safe

India’s cybersecurity agency, CERT-In, has issued an advisory regarding high-severity vulnerabilities in various Microsoft products, including multiple versions of Windows, Windows Server, Microsoft Office, and the Chromium-based Microsoft Edge browser. These vulnerabilities can allow attackers to execute malicious code, elevate system privileges, access sensitive data, or disrupt services. They arise from issues such as improper input validation, memory corruption, insufficient access control, and inadequate memory object handling. Exploitation can occur remotely or locally, sometimes requiring user interaction. CERT-In advises users and organizations to apply the latest security updates from Microsoft to mitigate these risks.

Why developers are betting on Postgres for AI

Organizations are intensifying the development of AI applications and agents, which rely on access to existing enterprise data to avoid inaccuracies in responses, a phenomenon known as "hallucination." Jensen Huang, CEO of Nvidia, and Phillip Merrick, co-founder of pgEdge, emphasize that structured data is essential for AI effectiveness. PostgreSQL is highlighted as a preferred database for AI applications, with 66% of respondents in the Stack Overflow 2025 Developer Survey indicating they wish to continue using it. Merrick notes PostgreSQL's advantages, including its open-source model, scalability, and ability to handle both structured and unstructured data. The pgEdge toolkit supports the entire lifecycle of AI application development, including document ingestion and vector embedding generation. PostgreSQL offers deployment flexibility and robust security features, making it suitable for critical sectors like finance and healthcare.

Android Hackers Target 800 Banking, Crypto and Social Media Apps With ‘Near-Zero Detection Rates’: Zimperium

Android hackers are targeting over 800 applications in banking, cryptocurrency, and social media sectors, utilizing four active malware families: RecruitRat, SaferRat, Astrinox, and Massiv. These malware employ advanced techniques to evade detection and execute credential theft, unauthorized financial transactions, and data exfiltration. Attackers lure victims through phishing websites, fraudulent job offers, fake software updates, text-message scams, and promotional lures. Once installed, the malware can request Accessibility permissions, obscure app icons, obstruct uninstallation, and steal sensitive information through counterfeit lock screens. They can also capture one-time passcodes, stream device screens, and overlay fake login pages on legitimate applications. The malware uses HTTPS and WebSocket communications to blend malicious traffic with normal activity and may incorporate encryption layers to avoid detection.

Fileless Malware and Email Authentication Gaps

Fileless malware operates stealthily within networks, utilizing legitimate system tools like PowerShell and Windows Management Instrumentation (WMI) to execute malicious code in memory without leaving traces on disk. Traditional antivirus solutions struggle to detect these threats due to their reliance on file signatures. The primary vector for fileless malware is email, where attackers use spoofed messages to trick users into activating malicious scripts. Misconfigurations in Sender Policy Framework (SPF) and DomainKeys Identified Mail (DKIM) records create vulnerabilities that attackers exploit to deliver spoofed emails. Traditional endpoint protection mechanisms are inadequate against fileless attacks, necessitating a shift towards behavioral analysis for detection. Organizations must assess their preparedness by ensuring proper email authentication configurations and enhancing endpoint security capabilities. Integration among security teams and updated employee security awareness programs are also essential. Sendmarc helps organizations mitigate vulnerabilities by providing visibility into SPF, DKIM, and DMARC configurations and enforcing DMARC to block unauthenticated messages.

Google Verified Email delivers powerful boost to Android app signups

Google Verified Email is a feature that streamlines the email confirmation process on Android devices by eliminating the need for one-time passwords (OTPs) or link tapping. It uses Android’s Credential Manager to store a cryptographically verified email credential on the device. When a user interacts with an email field or a sign-up button, a prompt requests permission to share the verified email with the app, allowing for instant confirmation without leaving the screen. This feature currently supports consumer Google Accounts on devices running Android 9 or later with updated Google Play services. Apps cannot access user information without explicit consent, and the feature can also be used for account recovery and profile modifications. Developers can use the Credential Manager API, which is issuer-agnostic, but Google’s credential specifically verifies only the email address. Despite its benefits, Google recommends maintaining backup options like manual email entry or traditional OTPs for situations where no suitable credential is available.

Engineering secure passkey sync in Microsoft Password Manager

Passkeys are a new form of authentication that replace traditional passwords, providing a phishing-resistant and streamlined sign-in process. Microsoft Password Manager allows users to save and synchronize passkeys across devices linked to their Microsoft accounts, enhancing accessibility. The architecture for passkey syncing includes confidential computing for sensitive operations, hardware-rooted key protection for encryption keys, tamper-evident recovery storage, and encrypted synchronization across devices. Sensitive passkey operations are executed in Azure's confidential computing environments, ensuring cryptographic materials are processed securely. The encryption keys are protected using Azure Managed HSM, with access governed by attestation-based mechanisms. Registration and recovery processes require user authentication and enforce security measures within confidential computing boundaries, including a lockout state after consecutive incorrect PIN attempts. The system aims to provide a secure and user-friendly experience as part of a transition to a passwordless future.
