Microsoft Warns of GigaWiper Backdoor Built to Destroy Windows PCs

Microsoft has unveiled a destructive Windows backdoor named GigaWiper, which allows operators remote control over compromised systems to execute irreversible damage. GigaWiper originated from cyberattacks in October 2025 and is a composite of code from at least three malware families. It maintains its presence through a scheduled task disguised as “OneDrive Update,” executing at startup and every minute. GigaWiper can obliterate partition information, overwrite physical drives, and restart systems. It also mimics ransomware by encrypting files with the .candy extension, using randomly generated keys that are not stored, making recovery impossible. The malware has connections to the Crucio ransomware and resembles FlockWiper, with rewritten code in Go. GigaWiper features 20 command codes for various functions, including executing PowerShell instructions, managing processes, capturing screenshots, and remote access similar to VNC. It can remain on a system for surveillance until its destructive functions are activated. Microsoft Defender includes detection capabilities for GigaWiper, and users are advised to enable tamper protection and monitor for suspicious activities.

Microsoft Details Windows Clipper Malware Campaign Using USB LNK Worm and Tor-Based C2

Microsoft has identified a Windows-based cryptocurrency clipper campaign that has been active since February 2026. This campaign uses clipboard-intercepting malware with self-spreading capabilities and operates through the Tor network. The clipper malware employs Windows Script Host and ActiveX to launch a Tor proxy and connect to a hidden command-and-control server. It focuses on stealing clipboard data, particularly cryptocurrency wallet addresses, and can exfiltrate screenshots. The malware is distributed via malicious Windows Shortcut (LNK) files on USB drives, which activate a worm that checks for existing infections and fetches the payload from a remote server. The clipper monitors the clipboard every 500 milliseconds for sensitive information and can replace copied wallet addresses with those controlled by attackers. Microsoft recommends behavioral detections, disabling AutoRun for removable media, blocking LNK execution from drives, and monitoring clipboard-related activities as mitigations against this threat.

Windows SprySOCKS Malware: Advanced Kernel-Level Rootkit Targets Government Organizations via Supply Chain Vulnerabilities

The Windows variant of SprySOCKS malware, developed by the Chinese threat group Earth Lusca, targets government entities globally and features advanced capabilities such as rootkit-level stealth and extensive command-and-control (C2) functionalities. It operates on Windows systems, utilizing two main variants: WINDRV, which includes kernel drivers for stealth operations, and WINPLUS, a streamlined backdoor. The malware can communicate over TCP, UDP, and WebSocket, offering over 30 C2 commands for various operations, including system information gathering and keystroke logging. WINDRV loads a driver named ‘RawWNPF’ into memory using another signed kernel driver, allowing it to conceal processes and achieve persistence. The malware's design incorporates open-source elements and exploits vulnerabilities in the software supply chain, notably using a leaked certificate for driver signing. To combat SprySOCKS, organizations are advised to implement advanced endpoint detection and response (EDR) solutions, maintain regular patching, and manage supply chain risks vigilantly. The malware's adaptability and reliance on legitimate certificates complicate detection efforts, necessitating continuous refinement of security practices.

What Is OneLaunch.exe? Pros, Cons, and How to Remove It

OneLaunch is a software application that creates a personalized dock and desktop environment on Windows computers, often pre-installed or bundled with other software. It has received mixed reviews, with concerns about system slowdowns and its legitimacy. OneLaunch.exe is a background process supporting the OneLaunch application, which provides quick access to applications and updates but can consume system resources. The OneLaunch browser, installed alongside the main application, can alter browser settings and redirect searches, potentially leading to unwanted advertisements. While OneLaunch is not classified as traditional malware, it is often categorized as a Potentially Unwanted Program (PUP) due to its bundled installation and ability to modify system settings. It can monitor browsing habits and share data with third-party advertisers. Users report intrusive behavior, such as altering default browser settings, and it can negatively impact system performance. To remove OneLaunch, users should end the running process, uninstall the application, delete leftover folders, remove startup entries, and reset browser settings. OneLaunch may reappear due to accidental reinstallations, active browser extensions, lingering scheduled tasks, or hidden companion programs. Preventative measures include downloading from official sources, reading installation screens carefully, keeping systems updated, and performing regular system checks.

PHANTOMPULSE RAT Uses UAC Bypass to Hijack Windows Systems

PHANTOMPULSE is a remote access trojan (RAT) used as a final payload in multi-stage attacks targeting Windows environments. It employs advanced post-exploitation techniques, including process injection, User Account Control (UAC) bypass, and a decentralized blockchain-based command-and-control (C2) mechanism. The malware utilizes three process injection techniques: module stomping, manual DLL mapping, and debug-driven execution. It avoids detection by using direct system calls instead of standard Windows APIs and incorporates a hardware breakpoint mechanism to disable security protections like AMSI and ETW. PHANTOMPULSE retrieves its C2 server address from Ethereum-based transaction data but has a vulnerability that allows defenders to hijack communication. It achieves persistence through scheduled tasks and supports self-healing capabilities. Privilege escalation is done using the "schuac" UAC bypass technique. The malware conducts system reconnaissance focusing on cryptocurrency wallets and messaging apps but does not directly steal credentials. It shows signs of AI-assisted development and shares tactics with DPRK-aligned threat groups, particularly in targeting cryptocurrency platforms.

New PHANTOMPULSE RAT Campaign Uses UAC Bypass in Windows Attacks

The REF6598 intrusion set has revealed a Remote Access Trojan (RAT) named PHANTOMPULSE, which is distributed via malicious Obsidian plugins. It uses advanced evasion techniques, including a blockchain-based command and control (C2) channel and a public User Account Control (UAC) bypass to infiltrate Windows systems. The malware disables security measures like the Antimalware Scan Interface (AMSI) and Windows Lockdown Policy (WLDP) through a hardware-breakpoint technique, allowing it to avoid detection by signature-based memory scanners. PHANTOMPULSE hides its core files in encrypted registry blobs and creates scheduled tasks that appear as .NET Framework updates. Its decentralized C2 framework queries public blockchains for operational data, but it lacks sender authentication, which can be exploited by defenders. The malware inventories the system for antivirus software and targets high-value applications. It employs a UAC bypass technique called “schuac” to gain elevated permissions. Analysts attribute this campaign to DPRK-aligned threat actors, particularly the BlueNoroff group, due to its focus on cryptocurrency wallets and blockchain exploitation. Defenders can identify new infrastructure by searching blockchain ledgers for a specific hex signature associated with the malware's C2 encryption routine.
