Hellminer.exe: Crypto-Mining Malware Analyzed, Comprehensive Removal Guide
Mar 22, 2024 at 11:51 pm
Hellminer.exe is a malicious software that consumes high CPU resources, exploiting the system for cryptocurrency mining. It infects systems through malvertising or dropper malware and employs anti-VM and anti-debug measures. Hellminer establishes persistence through registry modifications and WMI calls, utilizing a peer-to-peer command server network for enhanced resilience. Removal requires thorough scanning with anti-malware software to eliminate the malware and its backups.
Hellminer.exe: A Comprehensive Analysis of a Crypto-Mining Malware
Introduction
Hellminer.exe is a malicious software process that has been identified for its significant impact on system performance. This malware utilizes the host computer's resources to mine cryptocurrencies, primarily DarkCoin and Monero. Its presence can result in a noticeable decrease in system responsiveness and stability, as it allocates a substantial portion of the CPU's processing power to the mining process.
Nature of the Malware
Hellminer.exe is associated with a malicious coin miner, a type of malware designed to exploit the hardware of infected systems to generate cryptocurrency. The malware establishes vast networks of compromised computers, enabling hackers to maximize their profits. It consumes a significant amount of CPU power, typically up to 80%, to ensure optimal mining performance. This excessive resource utilization renders the affected system sluggish and inconvenient to use.
Infiltration Methods
Hellminer.exe primarily infiltrates user systems through malvertising (malicious advertising) on the Internet or via dropper malware. Malvertising involves the distribution of malware through legitimate-looking websites or advertisements. Dropper malware serves as a delivery mechanism for other malicious payloads, including Hellminer.exe. It is important to note that these spreading methods are commonly employed by various types of malware, indicating a potential risk of multiple infections within the compromised system.
Technical Analysis
Unlike other miners that rely on open-source mining software such as XMRig, Hellminer.exe appears to be written in Python, suggesting a private development. Upon launch, the malware initiates a series of anti-virtual machine (VM) and anti-debugging checks. It leverages Windows Management Instrumentation (WMI) to retrieve information about the CPU, searching for indications of virtualization. The malware then proceeds to enumerate services and processes, paying particular attention to traces of the VMware virtualization environment. This behavior suggests that the malware seeks to avoid detection in virtual environments commonly employed for malware analysis.
Following these initial checks, the malware's primary payload is activated. However, the information gathered during the initial stage may also be used to configure the mining process or contribute to the system fingerprint, providing valuable insights to the malware operators.
Persistence Mechanisms
To maintain a persistent presence within the compromised system, Hellminer.exe manipulates the Windows registry through a series of commands. This manipulation enables the malware to start the Windows error reporting service, increasing its privileges and providing a disguise. Additionally, it alters network security policies and forces the WMI Adaptation Service to recursively launch the payload, ensuring continuous execution.
Command and Control Architecture
Unlike some malware miners, Hellminer.exe does not establish extensive command-and-control (C2) communication. After completing its initial tasks, it transmits a packet of system information to a command server, indicating its readiness. In response, the C2 server provides a configuration file containing details about the mining pool and IP address to connect to.
Notably, the command servers used by Hellminer.exe exhibit a peer-to-peer architecture. Instead of relying on a traditional C2 server model, the malware utilizes a network of infected computers as command servers. This network structure significantly increases the resilience of the botnet by preventing disruption through the compromise of a single command server.
Removal Guide
Effective removal of Hellminer.exe requires the use of reputable anti-malware software. Such software employs scanning mechanisms to identify and quarantine malicious files and processes. GridinSoft Anti-Malware is a recommended solution that can effectively neutralize Hellminer.exe and its associated components. It is crucial to perform a comprehensive scan to ensure the complete eradication of the malware and any residual traces.
Prevention and Mitigation
The activity of miner malware is closely correlated with the fluctuations in cryptocurrency prices. As the value of cryptocurrencies rises, so does the prevalence of malware exploiting these digital assets. Malvertising remains a primary vector for the distribution of Hellminer.exe and other miner malware. To mitigate this threat, users should exercise caution when interacting with online advertisements, particularly those promoting free software or downloads. Scrutinizing the URL and avoiding websites with suspicious or unfamiliar addresses can help prevent malware infections.
