Microsoft Removes WMIC from Windows 11 After Years of Abuse as LOLBIN by Ransomware and Attackers
Microsoft has started the final removal of the legacy command-line utility WMIC from Windows 11. The tool is already missing from new installations of versions 24H2 and 25H2, is no longer offered as an optional component, and has disappeared from the latest beta builds of the operating system.
WMIC allowed administrators to manage Windows Management Instrumentation through text commands, retrieving information about hardware, processes, services, and security software while also executing administrative operations. The core WMI technology itself remains intact; only the old command-line interface has been retired.
Microsoft has been preparing this deprecation for years. WMIC was first marked as deprecated in Windows Server 2012, then again in Windows 10 21H1. In Windows 11 22H2 it was moved to optional components, later disabled by default, and is now being fully removed.
The decision stems not only from the tool's age but also from its widespread abuse as a LOLBIN. Attackers have long used the signed Microsoft binary instead of deploying suspicious executables. Ransomware groups have employed WMIC to delete shadow copies, preventing victims from restoring encrypted data. Other threat actors have used it to discover installed security products, disable them, or add exclusions to Microsoft Defender.
Administrators are advised to transition to PowerShell, the COM API for WMI, .NET libraries, and contemporary scripting languages. Existing scripts that rely on WMIC commands will need to be rewritten after the update, or automation workflows will stop functioning.
The change reduces the number of built-in tools available to attackers but also removes a familiar utility from the toolkit of system administrators.

Cloudflare Blocks 18.2 Million DDoS Attacks in Q3 2026 Amid Shifting Attack Patterns
Cloudflare reported blocking 18.2 million network-layer DDoS attacks between July and September 2026, marking a 208% increase from the same period in 2025. The company recorded an average of roughly 8,200 attacks per hour, with 96% lasting under ten minutes and 98% staying below 1 Gbps. Large-scale attacks exceeding 1 Tbps dropped sharply from 805 in Q2 to 251 in Q3, a decline Cloudflare links to early 2026 law enforcement actions against four IoT botnets. Attack vectors shifted notably, with CLDAP reflection falling 99.5% while DNS amplification rose 215% and UDP floods grew 122%. The United States led targeted countries, followed by China and Indonesia, while media and publishing remained the most affected industry. Mirai variants accounted for 46.5% of network-layer bytes, with new families such as Dysphoria and Evooo1Bot emerging to replace dismantled botnets.
Freshko: Open-Source Rust Tool Offers Local File and URL Scanning Without Data Upload
A developer has released Freshko, a compact 400x640 pixel desktop application built in Rust that performs quick local checks on files, folders, and URLs without sending data to external services. The tool uses YARA-X rules for file scanning, follows up to eight redirects while querying Cloudflare's filtering DNS, and scores processes for potential cryptocurrency miners based on names, arguments, and launch paths. It explicitly avoids acting as a full antivirus solution, instead providing transparent results that list any skipped items or incomplete checks. Freshko runs on macOS and Windows, keeps all scan results in memory only, and disables system proxies during URL checks to prevent DNS rebinding attacks. The project includes performance benchmarks on Apple Silicon and addresses common pitfalls such as high CPU usage false positives and incomplete disk scans. Unlike VirusTotal or Cloudflare URL Scanner, Freshko performs all file analysis locally and never makes scan reports public.
Yoba Campaign Uses Signed ChatGPT and Claude Binaries for DLL Sideloading and XMRig Deployment
Researchers at Check Point Research have uncovered the Yoba malware campaign that distributes fake desktop clients for ChatGPT and Claude through GitHub repositories. The attackers bundle legitimate signed executables from OpenAI and Anthropic with a malicious DLL that gets loaded via classic sideloading. Once executed, the loader establishes persistence using the Windows Task Scheduler and retrieves additional payloads through Telegram, DNS over HTTPS, and the Catbox file hosting service. The campaign ultimately deploys the XMRig cryptominer, which pauses mining activity when user interaction is detected to avoid detection. No compromise of OpenAI or Anthropic infrastructure was found; the attackers simply repurpose the companies' signed binaries and reputation. The operation primarily targets home users and small-to-medium businesses with Windows systems.
uCreator Spyware Infiltrates Modified Telegram, WeChat and GCash Builds on Android
Security researcher Ovi has published a detailed analysis of uCreator, also known as YingGai, a commercial Android spyware platform designed for surveillance and remote app control. The malware intercepts messages, verification codes and account data directly inside legitimate applications without requiring root privileges. Infection vectors include tampered Telegram, WeChat and GCash APKs distributed through unofficial sources, as well as the Onion Box container that launches the target app inside a controlled environment. Once active, uCreator hooks into the host process, reads Telegram’s local message database through client interfaces, captures two-factor authentication passwords and hides its own session from the user. The operation is supported by cloud-based command panels and exposed GitLab repositories that revealed server-side code and development history. Compatibility problems have been noted on Android 17, and the total number of victims remains unknown.
