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.

Windows 11 sandbox flaw lets attackers escape with one click

SafeBreach Labs identified a vulnerability in Windows 11, named Click Or Trick, cataloged as CVE-2025-59199, which was addressed by Microsoft in October 2025. The vulnerability allows a one-click attack from a low-integrity process to achieve arbitrary write capabilities and escalated code execution by exploiting built-in Windows components. The researchers discovered a COM object with an undocumented flag that enabled a low-integrity process to launch a medium-integrity server process using the user's logon token. They found that certain applications could accept command-line parameters through notifications, allowing attackers to execute commands. The Snipping Tool was leveraged to transition execution to another registered application, such as Microsoft Teams, enabling the injection of a remote debugging switch. This exploit chain involved multiple Windows subsystems and was assigned a CVSS score of 7.8.
