ClamAV Setup: Linux Antivirus in 12 Steps [2026]

Malware can threaten Linux systems, which are often mistakenly believed to be immune to viruses. It can be introduced through email attachments, infected files, or compromised plugins, especially when Linux servers interact with Windows clients or handle internet uploads. ClamAV is an open-source antivirus engine maintained by Cisco Talos, designed for scanning mail traffic and file uploads. As of mid-2026, the stable release is ClamAV 1.5.x, with version 1.5.2 being the latest patch. To deploy ClamAV, users need root or sudo access on a compatible Linux machine, at least 2 vCPUs and 2GB of RAM, 5GB of free disk space, and outbound HTTPS access to ClamAV’s signature mirrors. The installation process involves several steps, including configuring freshclam for automatic updates, validating detection with the EICAR test file, and setting up cron jobs for regular scans. ClamAV can also be integrated with mail servers and a SIEM for enhanced security. Common pitfalls in deployment include skipping the initial freshclam run and using clamscan instead of clamdscan for repeated scans. ClamAV is free for commercial use and can also scan Windows systems, although it does not replace comprehensive endpoint protection solutions.

North Korea Buried Four-Stage Malware in Flag Images: Zero Antivirus Detections

North Korea's Contagious Interview hackers have been using a deceptive strategy to target developers by posing as recruiters and embedding malware in SVG files. Elastic Security Labs discovered that the attackers hid malicious payloads within HTML comment blocks of these files, allowing the malware to evade antivirus detection. At the time of the findings, no antivirus engines flagged the compromised repositories, which included trojanized GitHub repositories disguised as coding challenges. The malware executed automatically at server startup and deployed four modules: a browser credential and cryptocurrency wallet stealer, a file stealer, a remote access Trojan, and a clipboard monitor. The campaign, tracked as REF9403, is part of the ongoing Contagious Interview operation attributed to North Korea's Lazarus Group, which aims to generate revenue through cryptocurrency theft. Developers are advised to audit any projects run from unsolicited sources and to monitor specific domains associated with the attack.

Cursor Flaw Lets Malicious Cloned Repositories Trigger Windows Code Execution

Cursor, a development tool, has a security vulnerability that allows arbitrary code execution by simply opening a project repository on Windows. This flaw, reported by AI security firm Mindgard, is due to the presence of a file named git.exe in the project root, which Cursor executes automatically without user prompts. Mindgard demonstrated this vulnerability by renaming Windows Calculator to git.exe and placing it in the project root, leading to multiple instances of Calculator launching upon opening the repository. Cursor has not yet released a patch or advisory for this issue, which was first reported on December 15, 2025, and remains in the latest version, 3.11, released on July 10, 2026. Users are advised to implement workarounds, such as using AppLocker or Windows App Control to block executables by name and path. Other vendors, including GitHub and Google, have encountered similar vulnerabilities, but none have released fixes. The issue highlights the risks associated with untrusted search paths in software development.

GigaWiper: Anatomy of a destructive backdoor assembled from multiple malware

Microsoft Threat Intelligence has identified the GigaWiper malware, which has been detected in compromised environments since October 2025. This malware has destructive capabilities and comes in two forms: standalone wiper binaries and larger binaries with backdoor functionalities, both developed in Golang. The standalone wiper operates at the physical disk level, overwriting disk content and removing partition references. The backdoor variant includes the same wiper functionality and adds persistence through a registry key and scheduled tasks, along with command and control communication via RabbitMQ and Redis. GigaWiper can execute various commands, including wiping drives, triggering a Blue Screen of Death (BSOD), file encryption that mimics ransomware behavior, and managing system elements. The malware integrates components from multiple malware families, including wipers and ransomware mechanisms, and has been linked to a previous malware known as FlockWiper. To defend against GigaWiper, organizations are advised to implement security measures such as tamper protection, blocking access to known C2 infrastructure, and utilizing endpoint detection and response solutions. Microsoft Defender provides detections for GigaWiper and related malware, and threat intelligence reports are available for customers to stay informed about threats. Indicators of compromise include specific SHA-256 hashes and IP addresses associated with GigaWiper.

Evolving Windows vulnerability management to meet the speed of AI-powered discovery

Microsoft is enhancing its security measures for Windows by integrating artificial intelligence (AI) to improve the discovery and analysis of vulnerabilities across its codebase. This includes the use of a multi-model agentic scanning harness (MDASH) that employs various AI models to identify and validate potential vulnerabilities efficiently. A dedicated cloud infrastructure supports this scanning process, which aims to minimize false positives and reduce the time from discovery to customer protection. The company collaborates across divisions to promote AI-powered tools and practices, refining its internal systems to integrate vulnerability discovery into development processes. This includes updating Secure Development Lifecycle (SDL) practices to address AI-enabled attack techniques. Customers can expect an increase in security updates as AI enhances vulnerability discovery capabilities. Windows updates undergo rigorous validation through programs like the Security Update Validation Program (SUVP) to ensure quality and compatibility. Microsoft also offers tools like Known Issue Rollback (KIR) for quick reversion of changes if issues arise during updates. Customers are encouraged to stay current with security updates and utilize resources like the Security Update Guide for prioritizing protections. To facilitate smoother update processes, Microsoft provides optional non-security preview releases for compatibility testing and employs modern management capabilities like Windows Autopatch to automate security updates. Azure Arc enables rebootless updates for Windows Servers, while Microsoft Defender and Intune help manage vulnerabilities and compliance across endpoints. Overall, Microsoft is committed to continuous improvement in its security practices to adapt to the evolving threat landscape and ensure customer protection through timely updates.

Former Microsoft engineer shrinks Notepad down to size

Dave Plummer, a former Microsoft engineer, has created TinyRetroPad, a minimalist text editor that is only 2.5 kilobytes in size. It aims to provide a simple text editing experience, reminiscent of older software like Notepad, which has become bloated over time with unnecessary features. TinyRetroPad includes essential functions such as Open and Save As dialogs, font selection, and printing capabilities, while using assembly language and the RICHEDIT50W from the WinAPI. The application requires more system resources to run effectively but focuses on maintaining lean code and binaries.
