Windows 11’s driver signature requirement is one of the best anti-consumer security features out there

Windows 11 requires drivers to be digitally signed, a policy aimed at enhancing security by preventing unauthorized code from executing at the kernel level. This requirement, which began with Windows Vista and became mandatory with Windows 10, version 1607, has tightened over the years, especially with the introduction of UEFI Secure Boot and TPM in Windows 11. While this enforcement protects against malware and supports anti-cheat systems in gaming, it limits user autonomy and imposes significant challenges for developers, particularly those working on smaller projects. In contrast, Linux allows users more freedom to modify their systems, though this flexibility can compromise security.

Microsoft is ending support for Internet Explorer mode in Edge

Microsoft has announced that the Internet Explorer mode within its Edge browser will be supported until at least the end of 2029. This mode allows organizations to run IE's rendering engine on current Windows versions. Microsoft will provide a minimum of one year's notice before any end-of-support date. IE mode is a compatibility feature in Edge that uses the legacy Trident engine. Internet Explorer officially retired its standalone browser in June 2022, having dropped to less than 1 percent of the browser market share at that time.

The Best Small Business Cybersecurity Suites for 2026

A small business is typically defined as one where the owner can personally name all employees, usually comprising a workforce of a few dozen. Licensing options for IT protection for small businesses vary, with Malwarebytes and Norton covering up to 20 devices, ESET offering plans for five to 25 devices, and Bitdefender providing options for three, five, ten, or 25 users. Avast and AVG allow licenses for one to 999 devices. All security suites support Windows, and most, except AVG, also support Mac devices. Four suites offer protection for Android and iOS devices, while Avast and AVG do not support mobile devices. Bitdefender, ESET, and Norton provide dedicated server editions, while Avast and AVG allow individual policy definitions for servers. Remote installation features vary in reliability, but all suites enable administrators to manage installations and monitor device status. Norton offers backup solutions and 500GB of shared hosted storage, while firewall protection is standard except for Malwarebytes. Bitdefender and ESET provide anti-theft systems for lost devices, and both ESET and Avast have measures against unauthorized device access. Malwarebytes and Norton offer 24/7 priority support, and Norton provides dark web monitoring for sensitive information.

Cisco Talos Discloses Autonomous Windows Malware: Four AI Models Direct Each Attack

Cisco Talos has disclosed a Windows implant called CLOSEDQUORUM, which automates cyberattack execution using four advanced commercial large language models: DeepSeek, Qwen, Mistral, and Google Gemini. The implant is a 16.4-megabyte executable that conducts reconnaissance on the system and formats the gathered data into prompts for the AI models. Each model votes on one of four actions: steal, inject, persist, or move, with the action receiving the most votes being executed. When stealing, CLOSEDQUORUM targets three credential stores, dumping LSASS memory and retrieving saved passwords from browsers and cryptocurrency wallets. The stolen data is encrypted and sent to the operator via Discord. For injection, it uses Early Bird APC injection or process hollowing based on model responses. The persist action creates three mechanisms for longevity, including a Registry Run key, a scheduled task, and a WMI event subscription. CLOSEDQUORUM evades detection by suppressing ETW telemetry and delaying activity to avoid sandbox analyses. It connects to legitimate API endpoints, making blocking ineffective without disrupting enterprise applications. Talos recommends behavioral combination detection strategies and the use of a YARA rule for detection. The CAIRN toolkit has been introduced to detect AI-integrated malware without executing binaries. Unlike previous AI-assisted malware, CLOSEDQUORUM removes human decision-making from the attack process.

Hackers Disguise CHOSEN BRICK Malware as AI Apps, Antivirus Software and MRI Results

Iranian state-affiliated cyber actors are targeting dissidents, activists, and journalists using fake AI applications, counterfeit antivirus tools, and fabricated MRI scan results, primarily through a spyware family known as CHOSEN BRICK, which is designed for Windows systems. This campaign has been active since at least 2025 and affects individuals globally, including in the UK, US, and Netherlands. The malware establishes persistence via the Windows Registry Run key and communicates through Telegram, utilizing unique Bot IDs for each victim. CHOSEN BRICK is capable of extensive data collection, including capturing screenshots, recording audio, and stealing email content. Personal information from victims has been found on pro-Iranian leak sites, increasing harassment risks. Security measures should include monitoring for suspicious Registry entries and unusual communications, while users are advised to avoid unsolicited software installations and keep their systems updated. The FBI refers to this malware family as HEAVYGRAM.

Iranian spies hit Windows machines with Chosen Brick data-stealing malware

Iranian state cyber actors are targeting individuals through popular messaging applications, using surveillance and data-stealing malware known as "Chosen Brick," which has been in use since at least 2025. This malware is designed for Windows systems and enables the theft of personal data, allowing Iranian spies to monitor perceived threats such as dissidents, activists, and journalists. The attacks typically begin with messages sent via WhatsApp or Telegram, impersonating trusted contacts. Attackers conduct extensive research on their targets to craft convincing messages that encourage victims to download malicious files disguised as legitimate applications. Once executed, Chosen Brick operates stealthily, evading detection and establishing a connection for command-and-control communications. It can enumerate processes, capture screen and audio content, extract sensitive information, and even wipe infected systems. Organizations suspecting compromise are advised to engage IT providers for investigations and to inform staff about potential risks. Recent alerts follow cyberattacks on water and energy sectors linked to Iran, with ongoing concerns about the implications for cybersecurity amid escalating military tensions. Additionally, five US agencies have reported that attackers are using AI-generated scripts to exploit vulnerabilities in critical infrastructure systems.

8 Antivirus Software for Mac: Our Top Picks by Use Case (2026)

Apple provides built-in security features for macOS, including XProtect, Gatekeeper, and automatic malware removal, which contribute to the safety of Macs. However, these protections do not effectively address threats like infostealers, phishing, and adware. For enhanced security, third-party antivirus solutions are recommended. Bitdefender is noted for its strong detection rates and minimal system impact, making it suitable for most users. Intego specializes in Mac-specific threats and is ideal for users focused solely on Apple products. ESET and Trend Micro are recommended for businesses needing centralized management. F-Secure is recognized for its privacy-focused approach, while Norton offers a comprehensive suite of security features. AVG provides free real-time protection suitable for low-risk personal use, but may not be adequate for business needs. CleanMyMac is a maintenance tool rather than a traditional antivirus, focusing on system cleanup and optimization. Users should avoid running multiple real-time scanners simultaneously and ensure they purchase appropriate licenses for business use. It's important to evaluate the necessity of additional features and consider long-term pricing when selecting antivirus software.
