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 adds Windows protections for malicious Remote Desktop files

Microsoft has introduced new security measures for Windows 10 and Windows 11 to protect against phishing attacks that exploit Remote Desktop Protocol (RDP) connection files. These updates, part of the April 2026 cumulative updates (KB5082200, KB5083769, and KB5082052), include a one-time educational prompt for users upon first opening an RDP file, requiring acknowledgment of the associated risks. Subsequent attempts to open RDP files will display a security dialog with information about the file's publisher, the remote system address, and local resource redirections, with options disabled by default. If an RDP file is unsigned, a warning will indicate an "Unknown remote connection." These protections apply only to connections initiated through RDP files, not through the Windows Remote Desktop client, and can be temporarily disabled via the Windows Registry.

Microsoft rolls out fast-track to reinstate Windows hardware dev accounts

Microsoft has implemented a fast-track reinstatement process for developers whose Windows Hardware Developer accounts were suspended due to incomplete identity verification. This initiative follows complaints from developers, including those of WireGuard and VeraCrypt, about unexpected account terminations that hindered their ability to publish Windows drivers and updates. Microsoft clarified that the suspensions were communicated to partners since October 2025 and emphasized the importance of identity verification for signing and distributing kernel-level drivers. Developers can expedite their reinstatement by opening a support case with a business justification. Microsoft has also provided guidance for navigating the support workflow and an alternative contact for those facing difficulties.

WhatsApp Malware Campaign Uses VBS to Hijack Windows

Microsoft has identified a cyberattack campaign that uses WhatsApp messages to distribute malicious Visual Basic Script (VBS) files targeting Windows systems. First detected in late February 2026, the campaign employs social engineering to trick users into executing the VBS files, which then create hidden directories and disguise themselves as legitimate Windows utilities. The malware downloads additional payloads from cloud platforms like AWS, Tencent Cloud, and Backblaze B2 to establish persistence and escalate privileges. It can bypass User Account Control (UAC), alter registry settings, and install malicious MSI packages, including remote access tools like AnyDesk, to maintain continuous access for attackers.

Phishing Campaign Targeting Messaging Apps’ Users

A phishing campaign targeting users of messaging applications has been reported by the Cybersecurity and Infrastructure Security Agency (CISA) and the Federal Bureau of Investigation (FBI). This campaign exploits human behavior rather than software vulnerabilities, leading to the compromise of thousands of accounts worldwide, despite encryption. Attackers impersonate official support accounts and use social engineering tactics to prompt users to click on malicious links, request verification codes, or suggest account recovery actions. If users comply, attackers can take control of their accounts and may deploy malware. Platforms like Signal have been specifically targeted, but the tactics can apply to various messaging applications. Recommendations for users include being cautious with suspicious messages, avoiding unknown requests, carefully checking links, monitoring group chats for fake accounts, using built-in security features, and reporting incidents promptly.

Russian Intelligence targets American messaging app users, FBI says

FBI Director Kash Patel revealed that hackers linked to Russian intelligence are targeting the messaging accounts of high-profile U.S. individuals, including current and former government officials, military personnel, political figures, and journalists. The FBI has identified these cyber actors, who have gained unauthorized access to thousands of accounts globally, allowing them to view private messages, send impersonating messages, and conduct phishing attempts. The campaign specifically targets users of commercial messaging applications like Signal, which has been blocked in Russia due to alleged legal violations. Dutch intelligence agencies reported that Russian hackers are also engaged in a global cyber campaign against WhatsApp and Signal accounts, using phishing tactics to access sensitive information. Signal acknowledged recent targeted phishing attacks leading to account takeovers. Since Russia's invasion of Ukraine, its cyber operations have increasingly focused on disruptive tactics against Western allies.

What is the best PC antivirus for 2026: Acronis True Image vs. competitors

In 2026, traditional antivirus solutions are becoming outdated due to the rise of sophisticated cyber threats, including AI-driven ransomware and advanced phishing schemes. The FBI Internet Crime Report states that cybercrime losses exceeded .5 billion in 2023, with projections by Cybersecurity Ventures estimating costs could reach trillion annually by 2025. Research from IBM shows that organizations without a tested recovery plan face higher costs and longer downtimes. Built-in protections like Windows Defender and MacOS XProtect offer basic security but may leave gaps, necessitating comprehensive third-party antivirus solutions. Acronis True Image is highlighted for its unique combination of real-time malware protection and full system backup capabilities, enabling users to recover quickly from incidents. Other leading antivirus solutions, such as Norton 360, Bitdefender, McAfee, and Kaspersky, excel in threat prevention but lack integrated recovery options. Acronis emphasizes the importance of both security and continuity, preparing users for both cyber incidents and everyday failures.

Max Messenger: A fake data breach with genuine consequences?

A user claimed to have breached Max but later clarified that no large-scale breach or critical vulnerabilities were found. False claims about data breaches can cause significant reputational damage, as demonstrated by a Russian hacking group that falsely claimed to have accessed Epic Games' data, which was later admitted to be a ruse. Similarly, EuroCar reported that fake breach reports may have been generated by ChatGPT, misleading customers. Russian users are distrustful of the Max app, perceived as buggy and insecure. The Russian Federal Security Service blocked its integration with government services due to encryption concerns. Although the government pressures citizens to adopt Max, many may install it without using it regularly. There is skepticism among Russian citizens regarding the app's security, making them susceptible to damaging rumors. Future claims about Max Messenger data breaches are anticipated. Recommendations for organizations to protect against misinformation include maintaining a good reputation, being transparent if a breach occurs, and investing in digital forensics to counter false claims.
