A cyberattack campaign by the advanced persistent threat group Stealth Falcon targeted a prominent Turkish defense company using a zero-day vulnerability identified as CVE-2025-33053. This vulnerability allowed attackers to manipulate the working directory of legitimate Windows tools to execute malware from their WebDAV servers. The attack was initiated through a spear-phishing email containing a malicious .url file that directed the system to a legitimate Internet Explorer utility, which was then exploited to execute malicious files. The attackers employed process hollowing to bypass traditional defenses. Stealth Falcon, also known as FruityArmor, has been conducting cyber espionage since at least 2012, targeting government and defense sectors in Turkey, Qatar, Egypt, and Yemen. The attack involved a multi-stage infection chain leading to the deployment of "Horus Agent," a custom implant designed for advanced reconnaissance and equipped with anti-analysis techniques. Researchers identified additional custom tools used by Stealth Falcon, including a DC Credential Dumper and a custom keylogger. The group utilizes repurposed legitimate domains to blend their infrastructure with legitimate traffic, complicating detection efforts.

X Business, an e-commerce store specializing in handmade home décor, experienced a cybersecurity incident involving a malware strain called Chimera. The attack began during a routine update to their inventory management system and escalated within 12 hours, resulting in halted customer orders, locked employee accounts, and a crashed website. The attackers demanded a ransom of 0,000 in cryptocurrency, threatening to expose sensitive customer data. Chimera is an AI-driven malware that adapts its code to evade detection, targeting both Windows and macOS systems. It exploited a zero-day vulnerability in Windows' Print Spooler service and bypassed macOS security measures by forging code signatures. The malware used social engineering tactics to deceive employees into activating malicious payloads, leading to compromised systems and encrypted customer data. The recovery process took 48 hours, utilizing cybersecurity tools like CrowdStrike Falcon and SentinelOne Singularity to identify and isolate the malware. Data restoration was achieved through Acronis Cyber Protect and macOS Time Machine, while vulnerabilities were addressed with Qualys and emergency patch deployment via WSUS. The network security framework was improved using Cisco Umbrella and Zscaler Private Access to implement a Zero Trust architecture. The incident highlights the need for small enterprises to adopt proactive cybersecurity strategies, including a 3-2-1 backup approach, Zero Trust models, investment in AI-driven defense tools, and employee training to recognize social engineering attempts.

The end of support for Windows 10 is on October 14, 2025. Windows 11 requires a minimum of 64 GB of storage for installation. A clean installation of Windows 11 typically uses about 27 GB for system files and 3 GB for preinstalled applications, while upgrading from Windows 10 may require more than 64 GB. The storage needs may increase over time due to updates, and Windows 11 is designed to manage storage efficiently. Users can optimize their storage by uninstalling unnecessary applications, using the Disk Cleanup tool, and transferring large files to cloud storage.
