Hackers Use Fake Windows Update Installers to Deliver OnyxC2 Credential Stealer

OnyxC2 is a sophisticated credential stealer available for a subscription fee of 0 per month, distributed through disguised lures such as fake Windows updates and legitimate software installers. It functions as a commercial product with features like an automated payload builder, tiered licensing, and a centralized web dashboard. The malware boasts a 99% detection-evasion rate, successfully evading major antivirus solutions during tests. It is developed in C++, utilizing direct system calls and mutating with each build to avoid detection. OnyxC2 collects data from around 210 applications, targeting 45 web browsers, password managers, cryptocurrency wallets, and FTP clients. The malware is delivered using DLL sideloading, where a password-protected archive contains a legitimate application and a malicious DLL. The attacker's DLL is disguised by inflating its size and is loaded by a trusted binary. The malicious code remains encrypted on disk and decrypts in memory to evade analysis. OnyxC2 communicates with a Cloudflare-fronted command-and-control server to manage infected hosts and execute commands like hardware registration and cookie uploads. The threat extends to business environments, targeting FTP and email clients, with stolen session cookies allowing ongoing access to corporate infrastructure. Implementing anti-data exfiltration controls is recommended as a mitigation strategy.

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.
