Cyber actors linked to Russia target messaging app users, FBI warns

The United States has issued a warning about cyber actors linked to Russian intelligence targeting users of commercial messaging applications, particularly Signal, compromising thousands of accounts worldwide. The FBI and CISA released a public service announcement detailing the operation's focus on individuals of “high intelligence value,” including U.S. government officials, military personnel, political figures, and journalists. Attackers have not breached the encryption of these platforms but manipulate users into disclosing credentials or linking devices. Russian intelligence-linked actors often pose as official support accounts, creating urgency to obtain security codes. Dutch intelligence agencies also reported a similar campaign targeting Signal and WhatsApp accounts of dignitaries and military personnel. Users are urged to be cautious of suspicious messages and to avoid sharing personal information. Signal reaffirmed that its encryption remains intact, emphasizing that vulnerabilities arise from user behavior rather than technical flaws in the application itself.

Best Free Antivirus in 2026: What You Get (and What You Don’t)

Free antivirus solutions have improved significantly, providing users with protection that was once exclusive to paid software. Major players in the market include Avast, Bitdefender, AVG, and Malwarebytes, each offering distinct features and limitations. While effective against common threats like viruses and malware, these free tools often lack advanced privacy tools and comprehensive security coverage. Avast One Basic offers real-time scanning and basic tools like a VPN and system cleanup, while AVG AntiVirus Free provides a streamlined user experience with a focus on simplicity. Avira Free Security includes additional features such as a basic VPN and privacy management tools, making it a more comprehensive free option. McAfee Free serves as an introduction to its broader ecosystem but lacks depth in protection. Free antivirus tools remain popular due to improved everyday protection, ease of use, and cost-effectiveness, especially for mobile users. They utilize cloud intelligence for better performance and can handle basic security needs. However, they may not suffice for users with high-risk profiles or those needing advanced privacy features. Key criteria for free antivirus solutions include core protection through real-time monitoring, seamless performance, user-friendly interfaces, and additional valuable tools. Limitations include basic protection against emerging threats, intrusive upgrade prompts, slower updates to threat databases, limited support options, and potential privacy trade-offs. Alternatives to free antivirus software include Bitdefender, Surfshark One, Norton 360, Avast Premium Security, and Avira Prime, which offer more robust protection and features.

Think Windows 11 is annoying? These 4 Windows XP “nightmares” were way worse

Windows XP was launched in 2001 without an active firewall or integrated antivirus, exposing users to malware. The Internet Connection Firewall was included but not enabled by default, and it wasn't activated until Service Pack 2 was released nearly three years later. Microsoft introduced its antivirus solution, Microsoft Security Essentials, in 2009. Internet Explorer 6, included with Windows XP, had significant security vulnerabilities, allowing malware to easily infiltrate systems. The transition from Windows 95/98 to NT caused driver compatibility issues, leading to troubleshooting challenges for users. Network sharing features were unreliable, with many users experiencing difficulties connecting multiple XP PCs and sharing printers. Windows XP reached its refined state with Service Pack 3 in 2008 and ended mainstream support in 2014. Despite this, it continues to be used in some modern applications, such as self-checkout registers.

Federal Circuit Finds that Antivirus Software is Abstract and Remands for Alice, Step Two

Columbia University faced a setback in its patent dispute with Gen Digital Inc. regarding U.S. Patents 8,074,115 and 8,601,322, which relate to an innovative virus detection method developed in the early 2000s. The method involved evaluating the behavior of suspicious code using an emulator and a model of expected behavior derived from data across interconnected computers. Columbia initiated legal proceedings in 2013, and after various developments, a jury awarded Columbia over million in royalties for willful infringement in 2022. However, the Federal Circuit ruled that the patent claims were not sufficiently specific and remanded the case for further examination of whether the claims could constitute an inventive concept. The ruling emphasized that patent eligibility is determined by the precise language of the claims.

Researchers Reveal ‘RegPwn,’ a Windows Registry Vulnerability That Granted SYSTEM Privileges

A Windows vulnerability named "RegPwn" (CVE-2026-24291) allows low-privileged users to elevate their access to full SYSTEM privileges. Discovered by the MDSec red team, it has been in use since January 2025 and was addressed in a recent Microsoft Patch Tuesday update. The vulnerability exploits the management of Windows accessibility features, which generate a registry key that grants full control to low-privileged users. When a user activates an accessibility tool, the configurations are copied into the local machine registry hive, which remains writable by the logged-in user. This creates an opportunity for manipulation, especially when user-controlled settings interact with the Windows Secure Desktop environment. An attacker can exploit this by modifying their user-level accessibility registry key and using an oplock on a system file, allowing them to replace the local machine registry key with a symbolic link to an arbitrary system registry key. This process operates under SYSTEM privileges, enabling the attacker to write arbitrary values to restricted areas of the Windows registry. MDSec demonstrated this technique to gain access to a SYSTEM-level command prompt. Microsoft has released security updates to address this vulnerability, and MDSec has made the exploit code available on GitHub for research purposes.

Microsoft to Block Windows 11 and Server 2025 Automated Installation After Critical RCE Vulnerability

Microsoft is implementing a two-phase initiative to disable the hands-free deployment feature in Windows Deployment Services (WDS) due to a critical remote code execution vulnerability (CVE-2026-0386) identified on January 13, 2026. This vulnerability arises from improper access control related to the Unattend.xml file, which is transmitted over an unauthenticated RPC channel, allowing attackers on the same network segment to exploit it. Successful exploitation could grant SYSTEM-level privileges and compromise OS deployment images. The initiative includes: - Phase 1 (January 13, 2026): The hands-free deployment feature will remain operational but can be disabled. New Event Log alerts and registry key controls will be introduced to enforce secure practices. - Phase 2 (April 2026): The hands-free deployment feature will be completely disabled by default for administrators who have not modified registry settings. Administrators can temporarily re-enable the feature by setting AllowHandsFreeFunctionality = 1, but this is not secure. Recommendations include reviewing WDS configurations, applying security updates, setting registry keys for secure behavior, monitoring Event Viewer for alerts, and considering alternative deployment methods. Microsoft’s KB article 5074952 provides further guidance for impacted organizations.
