New AI-Powered LameHug Malware from Russia's APT28 Targets Email

LameHug Malware Overview

Ukrainian authorities have identified a new malware strain named LameHug, which utilizes AI-powered large language models (LLMs) to generate execution commands on compromised Windows systems. This malware is linked to the APT28 hacking group, known to be associated with Russian military intelligence. The attacks target Ukraine’s security and defense sectors, utilizing phishing tactics to distribute malicious software.

LameHug Malware Functionality

LameHug is developed in Python and leverages the Hugging Face API to interact with the Qwen2.5-Coder-32B-Instruct LLM from Alibaba. This innovative use of LLMs allows for dynamic command generation, which can adapt during a compromise, potentially evading detection by security software.

According to CERT-UA, the malware is disseminated via emails that contain ZIP attachments disguised as official documents. These ZIP files house a .pif extension file built using the Python PyInstaller tool. The malware collects sensitive data, including system information and documents such as PDFs and Office files.

Key Features of LameHug:

• Command Generation: Utilizes API from Hugging Face to generate commands based on textual descriptions.
• Data Harvesting: Searches for and exfiltrates data from user directories, storing it in a designated folder before sending it to an attacker-controlled server.
• Polymorphic Capabilities: The ability to adapt command execution makes detection by traditional security tools more challenging.

APT28 Cyber Activities

APT28, also known as Fancy Bear, has been conducting cyber operations since at least 2004. This group has been actively targeting Ukraine, especially following the 2022 invasion. Recent reports indicate that APT28 attempted to compromise critical infrastructure, showcasing their intent to disrupt Ukrainian operations.

The group has a history of exploiting vulnerabilities in various software, including a zero-day vulnerability in MDaemon Email Server (CVE-2024-11182). The use of the LameHug malware further exemplifies their evolving tactics in cyber warfare.
