Signal isn’t broken — so how are hackers targeting the world’s ‘most secure’ chat app?

On April 26, hackers allegedly linked to Russian groups targeted the Signal messaging app with phishing attacks aimed at senior politicians. These attacks did not compromise Signal's end-to-end encryption; rather, they deceived users into providing access to their accounts through fake messages. Signal is operated by the non-profit Signal Foundation, founded in 2012 by Moxie Marlinspike with funding from Brian Acton, a co-founder of WhatsApp. Signal distinguishes itself by rendering metadata invisible to its operators, unlike WhatsApp, which shares user data with its parent company. Signal's president, Meredith Whittaker, advocates for data privacy.

Microsoft Defender: The Gold Standard for 2026 Security

Microsoft asserts that Microsoft Defender Antivirus is sufficient for most Windows 11 users as their sole security solution, following updates to the Windows security framework designed to counteract emerging threats. The current Windows security experience includes features such as real-time protection, cloud-delivered intelligence, smart app control, and cross-platform presence. Microsoft believes that the operating system itself is the most effective guardian of user data, embedding protections directly into the kernel to avoid performance slowdowns associated with external antivirus solutions. Despite this, the cybersecurity sector argues that specialized third-party software remains important, offering features like advanced password management and dedicated identity theft protection that Microsoft Defender lacks. The threat landscape in 2026 is increasingly driven by AI, prompting Microsoft to integrate AI into the Defender engine for proactive threat detection. While Microsoft Defender provides a robust baseline for security, a comprehensive strategy also requires good digital hygiene, strong password policies, and skepticism towards suspicious links.

A zero-day BlueHammer Windows exploit was leaked by a researcher fed up with Microsoft’s Security Response Center — and the rushed fix isn’t perfect

On April 2, 2026, a security researcher named Chaotic Eclipse announced a zero-day Windows exploit called BlueHammer, which allows attackers to gain SYSTEM privileges. Will Dormann, a principal vulnerability analyst, confirmed the exploit's functionality. Chaotic Eclipse criticized the Microsoft Security Response Center (MSRC) for its perceived incompetence, suggesting that prior attempts to resolve the issue privately were ignored. Dormann indicated that budget cuts at Microsoft may have led to a decline in the quality of the MSRC. BlueHammer was neutralized in the Windows 11 CVE-2026-33825 update released on April 14, 2026, but some components may still exist.

Aptoide sues Google for Android app store monopoly

Aptoide, a Portuguese app store company, has filed an antitrust lawsuit against Google in a federal court in San Francisco, alleging that Google is monopolizing the distribution of Android applications and payment processing. Aptoide claims that Google's practices hinder its ability to compete, despite offering lower commissions and more affordable options. The lawsuit seeks court orders to stop these practices and demands triple damages. Aptoide previously won a legal case against Google in 2018 regarding the removal of its app without user consent and was involved in the European Commission's Android antitrust case that resulted in a €4.34 billion fine against Google. The lawsuit comes amid increased scrutiny of Google's business practices, including a December 2023 jury ruling that found Google maintained an illegal monopoly in Android app distribution and in-app billing. Following this ruling, a U.S. District Court ordered Google to implement reforms to enhance competition within the Android ecosystem. Additionally, a proposed settlement between Google and Epic Games aims to facilitate the installation of third-party app stores and allow alternative payment methods. In August 2024, a U.S. District Court identified Google as a monopolist in the general search market, citing exclusionary agreements that restrict competition. Aptoide's lawsuit reflects concerns among smaller competitors about Google's influence over Android app distribution despite ongoing legal challenges.

Microsoft tightens Windows 11 driver security rules

Microsoft will enforce a new mandate requiring all hardware drivers to comply with the Windows Hardware Compatibility Program (WHCP) standards starting April 1, 2026. This change will eliminate the "cross-signing" system that allowed older drivers with expired certificates to remain trusted. The enforcement of WHCP certification will apply to various versions of Windows 11 and Windows Server 2025. Users may face blocks when installing older drivers on new systems, but existing installations will not be immediately disrupted. Microsoft plans to introduce an "allow list" for vetted legacy drivers to ensure essential equipment remains operational during the transition. The initial rollout will occur in "evaluation mode," allowing Microsoft to monitor driver behavior without blocking software. For corporate environments, Microsoft offers "Application Control for Business" to allow specific software while maintaining security measures.
