Microsoft Prepares Windows Code Signing for Stronger Cryptography

Microsoft has issued an advisory to IT teams and software developers regarding significant changes in Windows code signing due to the expiration of the Windows Production PCA 2011 certificate in October 2026. The transition will involve stronger cryptographic algorithms, including RSA-3072 and SHA-384, which may cause compatibility issues for applications that rely on hardcoded certificate checks or outdated cryptographic standards. Microsoft plans to implement post-quantum cryptography by default for Windows code signing in 2027. IT administrators are encouraged to assess their software environments, confirm vendor compliance with supported trust-validation mechanisms, and ensure applications are tested against the new certificate hierarchy and signing algorithms. Organizations with private trust stores must establish processes for recognizing and deploying legitimate Microsoft certificate updates.

Z-TEXT, a zk-SNARKs Blockchain Messenger, Launches Channels, Completing a 4-in-1 Privacy App on BitcoinZ

Z-TEXT has launched its Channels feature, transforming its platform into a comprehensive 4-in-1 privacy ecosystem built on the BitcoinZ blockchain. This system features a four-layer security architecture, including local device encryption, zk-SNARKs shielding, BitcoinZ blockchain settlement, and post-quantum protection. The Channels feature allows creators to maintain control over their broadcasts, with subscribers connecting directly through their wallets, ensuring no central authority can seize or delete subscriber information. Users can restore their channel and its history on any new device using a 24-word seed phrase. Z-TEXT emphasizes the importance of permanence in privacy, contrasting with the trend of automatic message deletion. The application requires no phone number, email, or SIM card for identity verification, relying solely on the 24-word seed phrase. Z-TEXT has been in closed beta without critical vulnerabilities and is preparing for public release on major app stores. The average message fee is approximately [openai_gpt model="gpt-4o-mini" prompt="Summarize the content and extract only the fact described in the text bellow. The summary shall NOT include a title, introduction and conclusion. Text: Z-TEXT, a pioneering zk-SNARKs blockchain messenger, has recently unveiled its innovative Channels feature, marking a significant evolution in its privacy-focused ecosystem. Built on the BitcoinZ blockchain, Z-TEXT is designed with a robust four-layer security architecture that includes local device encryption, zk-SNARKs shielding, BitcoinZ blockchain settlement, and post-quantum protection. The Shift to a 4-in-1 Privacy Ecosystem This launch signifies Z-TEXT's transformation from a conventional messaging platform to a comprehensive 4-in-1 privacy ecosystem. In this new paradigm, users' interactions are securely housed within their wallets rather than in centralized company databases. As Eric Pierrot, the founder of Z-TEXT LLC, aptly notes, "Needing to disappear is proof you can't survive the erosion of time—or what's coming with quantum computing." The Channels feature empowers creators by allowing them to maintain control over their broadcasts. Each subscriber connects directly to the channel through their own wallet, eliminating the risk of a central authority seizing, selling, or deleting subscriber information. This decentralized approach ensures that the integrity of the channel remains intact, regardless of external pressures. Subscribers can receive messages from the broadcaster at a fixed cost, whether the audience comprises ten or ten thousand individuals. In the event of a lost device, users can effortlessly restore their channel and its complete history on any new device using the same 24-word seed phrase that secures their entire account. A Commitment to Privacy and Permanence The launch of Channels builds upon Z-TEXT's commitment to privacy, a principle the company has championed since releasing its privacy manifesto on IPFS and timestamping it on the BitcoinZ blockchain earlier this year. While many messaging applications promote automatic deletion as a feature, Z-TEXT argues that true privacy is rooted in permanence. Pierrot emphasizes, "If your encryption actually holds, the message doesn't need to vanish to stay safe. Eternal memory is our signature—we built for permanence, not for disappearing." Having successfully navigated a closed beta phase without any critical vulnerabilities reported through its on-chain bug bounty program, Z-TEXT is now gearing up for a public release on major app stores, including Google Play and the Apple App Store. The application requires no phone number, email address, or SIM card, with identity verification based solely on a 24-word seed phrase. In addition to its messaging capabilities, Z-TEXT integrates a password manager and a crypto wallet, all while maintaining an impressively low average message fee of approximately [cyberseo_openai model="gpt-4o-mini" prompt="Rewrite a news story for a business publication, in a calm style with creativity and flair based on text below, making sure it reads like human-written text in a natural way.

Needing to disappear is proof you can't survive the erosion of time—or what's coming with quantum computing.”— Eric Pierrot, founder of Z-TEXT LLCSHERIDAN, WY, UNITED STATES, July 11, 2026 /EINPresswire.com/ -- Z-TEXT, a zk-SNARKs blockchain messenger, built on BitcoinZ, has launched Channels, a broadcast feature where the creator—not a platform—controls the channel. Each subscriber holds their own connection to the channel in their own wallet, so there is no central list a company can seize, sell, or delete. Channels joins Z-TEXT's existing privacy ecosystem of shielded messenger, password manager, and crypto wallet, all accessible through a single 24-word seed phrase.A single Channels transaction reaches any number of subscribers, from ten to ten thousand, at the same fixed cost. No company sits between the broadcaster and the audience with the ability to suspend the channel or hand over the subscriber list. If a device is lost, the channel and its full history can be restored on any new device using the same 24-word seed phrase that recovers the rest of the account.The launch extends a position Z-TEXT has held publicly since June, when the company published a privacy manifesto on IPFS and timestamped it on the BitcoinZ blockchain, arguing that permanence, not disappearing messages, is the stronger privacy guarantee. Most messaging apps market automatic deletion as a safety feature. "Needing to disappear is proof you can't survive the erosion of time — or what's coming with quantum computing," said Eric Pierrot, founder of Z-TEXT LLC. "If your encryption actually holds, the message doesn't need to vanish to stay safe.

Windows Platform Security and the Race to Secure AI Agents

Microsoft has introduced the Microsoft Execution Containers (MXC) SDK to establish Windows as a reliable operating system for autonomous agents, focusing on containment, identity, and manageability. The MXC framework serves as a policy-driven execution layer for agents on Windows and Windows Subsystem for Linux (WSL), allowing developers to set access permissions using JSON or TypeScript. It employs process and session isolation for agent containment and identity. Future enhancements will include micro-VM support for high-risk tasks and integration with Windows 365 for cloud PC workloads. IT teams can manage MXC policies through Entra ID and Intune, while Defender and Purview provide protection and observability. The MXC framework is built on Microsoft's security initiatives, including Secure Boot and passwordless sign-in, allowing agents to inherit a secure foundation. However, early commentary expresses caution regarding MXC's perception as a comprehensive security solution, noting issues with overly permissive policies and the lack of outbound network filtering. Other platforms, such as Linux, are also enhancing security for agents with kernel-level isolation and secure environments like NVIDIA's OpenShell runtime. Various projects are focusing on agent sandboxes within Kubernetes, employing technologies like gVisor and Kata Containers for isolation. Overall, no singular dominant platform security model for AI agents has emerged, with Windows' MXC still considered nascent compared to existing solutions in Linux and Kubernetes ecosystems.

1 Million Users Donate To Rescue Session Messenger From Shutdown

Session, a decentralized encrypted messenger, has over a million monthly users and has secured its future through community donations after facing a funding crisis earlier this year. The Session Technology Foundation had to reduce its paid staff and warned of a potential closure in July due to a significant financial shortfall. However, the community raised sufficient funds to prevent shutdown, allowing development to continue until at least 2027. The majority of contributions came from everyday users passionate about privacy communication. Session operates without requiring phone numbers and uses a decentralized network to enhance privacy. Under the leadership of Jason Rhinelander, the team is focusing on new features like post-quantum encryption. The organization also aims to achieve self-sustainability with a new paid Pro tier. Co-founder Chris McCabe's public appeal for support in March preceded staff layoffs on April 9, and Ethereum co-founder Vitalik Buterin previously donated 128 Ether (ETH) to assist the foundation.
