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.

Group-IB Discovers RemControl Android Banking Trojan Using Dynamic Overlay Attacks to Steal Banking PINs
Group-IB has identified a new Android banking trojan named RemControl with samples dating back to July 2026. The malware targets more than 30 financial institutions across Europe, the Middle East, and Canada, with Italy and France as primary focus areas. RemControl employs an overlay technique that displays a full-screen phishing replica of the legitimate banking app when the victim launches the real application, capturing PINs, access codes, and card details before seamlessly returning control to the authentic app. Phishing screens are not bundled in the APK but are fetched dynamically from operator-controlled servers reachable via Telegram channels, allowing rapid target changes without reinfection. Distribution relies on fake Google Play listing pages that mimic a streaming application, with geo-targeted delivery for Italian visitors. The trojan requests VPN permissions to block Play Store traffic and bypass real-time security checks, followed by accessibility service access that enables screen reading, keystroke logging, remote taps, and unlock pattern reconstruction.
Solar and F6 Integrate Solar webProxy with F6 Malware Detonation Platform to Filter Web Threats
GC Solar and F6 have confirmed compatibility between the Solar webProxy web access management system and the F6 Malware Detonation Platform. The integration allows Solar webProxy to pre-filter web objects and forward only suspicious files via the ICAP protocol to F6 MDP for reputation checks, static analysis, and dynamic detonation in an isolated virtual environment. Administrators can tune the level of filtering to avoid sending benign items such as fonts and icons to the sandbox, preserving resources for genuine threats. Data from the Solar webProxy team shows that archives accounted for an average of 37 percent of web threats in 2025, with malware frequently hidden inside ZIP, RAR, and 7Z containers. The solution targets medium and large organizations in finance, industry, and the public sector that handle high volumes of web traffic daily.
Engineer Tackles Jane Street ASIC Reverse Engineering Puzzle with Custom Simulator and Verilog Extraction
A detailed technical account describes how one engineer spent weeks reverse engineering an ASIC from GDS files provided in a Jane Street puzzle. The process began with parsing the GDS layout using the gdstk Python library to identify 27 cells in the warmup challenge and thousands of elements in the main task. The engineer built a custom logic simulator backed by SQLite, developed a domain-specific hardware description language, and eventually extracted a netlist that could be converted into Verilog for simulation. Key components identified included shift registers, an adder, and a comparator named comparitor496 in the warmup round. In the full challenge, nearly 10,000 instances of 81 different sky130 standard cells were processed, revealing an unexpected floating net that prompted a bug report to Jane Street. The effort combined manual schematic tracing, graph-based connectivity analysis, and waveform inspection with Surfer to confirm functional behavior.
EtherHiding Campaign Hides Banking Trojan C2 in Polygon Smart Contracts
Security researchers have detailed the EtherHiding campaign, which conceals command-and-control infrastructure inside smart contracts on the Polygon blockchain. The final payload is a malicious browser extension that functions as a banking trojan, intercepting credentials and two-factor codes from approximately 479 financial and cryptocurrency websites. Instead of embedding fixed addresses in its code, the malware queries an encrypted C2 server address from the smart contract, allowing operators to change destinations through low-cost blockchain transactions that bypass domain blocking. Infection begins when victims visit one of 31 compromised legitimate sites that inject JavaScript displaying a fake CAPTCHA prompt. The prompt instructs users to press Windows+R and execute a PowerShell command, a social engineering technique known as ClickFix that downloads the malicious scripts without exploiting any software vulnerability. The campaign has remained active from November 2025 through at least September 2026, demonstrating the resilience of blockchain-based infrastructure against traditional takedown methods.
