Decades-old file security flaws found in Android, Linux, macOS, and Windows

Security researchers from Graz University of Technology in Austria have discovered significant vulnerabilities in the file notification systems of major operating systems: Android, Linux, macOS, and Windows. These flaws have existed for decades and can lead to the leakage of sensitive system information. The affected systems include inotify on Linux (since 2005), FileObserver on Android (since 2008), ReadDirectoryChangesW on Windows (since 2000), and FSEvents on macOS (since 2007). The vulnerabilities allow unprivileged users to monitor file events without explicit read permissions, enabling potential attacks such as inter-keystroke timing attacks and website fingerprinting. For example, on Linux, monitoring a readable directory can leak events on files that cannot be read, allowing attackers to achieve a 93.1% to 100% accuracy rate in monitoring keystrokes. Specific vulnerabilities include CVE-2025-68788 on Linux, which received a partial fix in December 2025, and issues on Android where FileObserver can bypass app storage isolation. On macOS, limited information is available due to a lack of bypasses for private directories, while on Windows, monitoring the root directory can reveal the full path of every accessed file, allowing real-time tracking of web activity with a 97.8% accuracy rate. Microsoft has described the issue as "by-design," which has faced criticism. The researchers propose stronger mitigations, such as disallowing monitoring of entire drives on Windows and introducing a permission system for file monitoring on Windows and macOS. Their findings will be presented at the ACM CCS 2026 conference in November in The Hague, Netherlands.

Ando wants to take on Slack with a team messaging app that lets humans and agents work together

In 2025, Sara Du identified challenges in integrating AI agents within communication platforms like Slack while assisting companies with MCP servers. She criticized the design of these platforms for treating AI agents as separate applications rather than team participants. Du proposed a solution to eliminate intermediaries between AI agents and teams, envisioning a system where agents could engage directly in conversations, understand decisions, ask questions, and autonomously notify humans when necessary. Du's startup, Ando, launched as a messaging platform that allows both human and AI workers to communicate seamlessly, featuring channels, direct messages, and live calls. Ando has raised a million in pre-seed and seed funding from firms like Accel and Index Ventures. Despite existing competition from platforms like Slack and Microsoft, Du sees potential for Ando to disrupt the market by focusing on AI agent integration. Currently, Ando works with clients in software, real estate, and finance across 15 countries, primarily small teams, and aims to expand its capabilities with the new funding.

Chinese Hackers Exploit Chrome-Windows Zero-Day Chain to Deploy CLEANGULP Malware

A Chinese threat actor, codenamed UTA0565, has exploited newly disclosed vulnerabilities in Google Chrome (CVE-2026-85046, CVE-2026-87491) and Windows (CVE-2026-85880) through deceptive websites, achieving remote code execution. The attacks were detected on September 3 and 4, 2026, and involved impersonating organizations to mislead victims, particularly targeting Asian government entities with phishing emails related to Hong Kong activist Chow Hang-tung. The phishing messages directed users to fraudulent sites that loaded an HTML element using the BlueMoon exploit kit, which delivered a payload named "chrome_cleanup.exe," associated with the CLEANGULP malware family. This malware allows for command execution, process listing, file uploads and downloads, and uses a hard-coded domain for command-and-control communications. The exploit's widespread use suggests a coordinated effort within the Chinese cyber espionage community, with indications that multiple groups are sharing and weaponizing the exploit.

BigDiskBuster PoC Blocks Windows Defender Updates

A new tool named BigDiskBuster has been released on GitHub, which disrupts Microsoft Defender Antivirus by preventing it from installing updates. It does this by consuming available disk space during the update process, causing Defender to remain on its current version and unable to receive new platform or signature updates. BigDiskBuster operates as a local denial-of-service technique and requires prior access to the target machine to execute. The tool was created by researcher Abdelhamid Naceri, known as Nightmare Eclipse, who has previously worked on similar projects. As of now, there is no CVE identifier, patch, or advisory from Microsoft regarding this issue.

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.

RatHat Android Malware Uses AI to Target Banking Credentials in Real Time

A newly identified strain of Android malware, RatHat, utilizes generative AI to manipulate infected devices in real time. It is linked to threat actors believed to be operating out of China. RatHat serializes the device’s live Accessibility tree into XML format and communicates with a generative AI assistant to return screen coordinates, identify text, and issue navigation commands. The malware employs WebView-based HTML overlays to capture login credentials from banking and cryptocurrency applications and can infiltrate payment apps like WeChat and Alipay to extract PINs. It also features an SMS receiver and notification listener to intercept OTPs and 2FA codes. RatHat is disseminated through smishing, malvertising campaigns, and misleading third-party forums. It employs anti-analysis techniques such as container tampering, manifest bombing, DEX bytecode poisoning, string encryption, and anti-debugging. Once installed, it gains Accessibility access, activates Developer Options, and enables Wireless Debugging, allowing it to connect to the device's local ADB service and launch control agents with shell-level privileges. The malware captures raw touch coordinates to reconstruct PINs and unlock patterns, bypassing screenshot protections. It also includes persistence mechanisms that prevent uninstallation by presenting a fake Google Play failure overlay and automatically reinstalling itself if removed.

Do You Really Need Antivirus in 2026?

The landscape of computer security has changed significantly over the past two decades. In 2026, antivirus protection remains important, but the need for separate third-party programs has decreased for many users due to the built-in Microsoft Defender in Windows 11, which is activated by default and effectively blocks 100% of common malware samples according to independent testing by AV-TEST. Windows 11 also includes additional protective features like SmartScreen and a robust Firewall. While dedicated security suites from companies like Norton and Bitdefender offer advanced functionalities, many users may find adequate protection with the built-in tools. Research from AV-Comparatives indicates that performance varies among security programs, particularly against real-world attacks. Phishing attacks accounted for approximately 60% of initial access points in incidents examined by the ENISA Threat Landscape report from 2025, highlighting that user behavior is a significant vulnerability. Modern web browsers and operating systems have enhanced their security measures, with Google Chrome, Microsoft Edge, macOS, and Android incorporating features to protect users from harmful websites and downloads. For the average Windows 11 user who keeps their system updated and practices safe browsing, built-in protection is generally sufficient, though paid antivirus options can provide additional tools.
