Hellminer.exe: A Comprehensive Analysis of a Crypto-Mining Malware

Hellminer.exe：加密货币挖矿恶意软件的综合分析

Introduction

介绍

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.

Hellminer.exe 是一个恶意软件进程，已被确定对系统性能有重大影响。该恶意软件利用主机的资源来挖掘加密货币，主要是 DarkCoin 和 Monero。它的存在可能会导致系统响应能力和稳定性显着下降，因为它将 CPU 处理能力的很大一部分分配给了挖掘过程。

Nature of the Malware

恶意软件的性质

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.

Hellminer.exe 与恶意硬币挖掘程序相关，这是一种旨在利用受感染系统的硬件生成加密货币的恶意软件。该恶意软件建立了庞大的受感染计算机网络，使黑客能够最大化利润。它会消耗大量的 CPU 功率（通常高达 80%），以确保最佳的挖矿性能。这种过度的资源利用导致受影响的系统运行缓慢且不方便使用。

Infiltration Methods

渗透方法

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.

Hellminer.exe 主要通过互联网上的恶意广告（恶意广告）或通过植入式恶意软件渗透用户系统。恶意广告涉及通过看似合法的网站或广告传播恶意软件。 Dropper 恶意软件充当其他恶意负载（包括 Hellminer.exe）的传递机制。值得注意的是，这些传播方法通常被各种类型的恶意软件所采用，这表明受感染系统内存在多重感染的潜在风险。

Technical Analysis

技术分析

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.

与其他依赖 XMRig 等开源挖矿软件的矿工不同，Hellminer.exe 似乎是用 Python 编写的，这表明是私人开发。启动后，恶意软件会启动一系列反虚拟机 (VM) 和反调试检查。它利用 Windows Management Instrumentation (WMI) 检索有关 CPU 的信息，搜索虚拟化的迹象。然后，恶意软件会继续枚举服务和进程，特别关注 VMware 虚拟化环境的痕迹。此行为表明恶意软件试图避免在通常用于恶意软件分析的虚拟环境中进行检测。

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.

在这些初步检查之后，恶意软件的主要有效负载被激活。然而，在初始阶段收集的信息也可用于配置挖掘过程或贡献系统指纹，为恶意软件操作者提供有价值的见解。

Persistence Mechanisms

持久化机制

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.

为了在受感染的系统中保持持久存在，Hellminer.exe 通过一系列命令操纵 Windows 注册表。这种操作使恶意软件能够启动 Windows 错误报告服务，从而增加其权限并提供伪装。此外，它还会更改网络安全策略并强制 WMI 适应服务递归启动有效负载，以确保连续执行。

Command and Control Architecture

命令与控制架构

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.

与某些恶意软件挖矿程序不同，Hellminer.exe 不会建立广泛的命令与控制 (C2) 通信。完成初始任务后，它将系统信息包发送到命令服务器，表明其已准备就绪。作为响应，C2 服务器提供一个配置文件，其中包含有关矿池和要连接的 IP 地址的详细信息。

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.

值得注意的是，Hellminer.exe 使用的命令服务器呈现出点对点架构。该恶意软件不依赖传统的 C2 服务器模型，而是利用受感染计算机的网络作为命令服务器。这种网络结构可防止单个命令服务器受到破坏而造成破坏，从而显着提高僵尸网络的弹性。

Prevention and Mitigation

预防和缓解

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.

矿工恶意软件的活动与加密货币价格的波动密切相关。随着加密货币价值的上升，利用这些数字资产的恶意软件也越来越流行。恶意广告仍然是传播 Hellminer.exe 和其他矿工恶意软件的主要媒介。为了减轻这种威胁，用户在与在线广告互动时应小心谨慎，尤其是那些宣传免费软件或下载的广告。检查 URL 并避开具有可疑或陌生地址的网站可以帮助防止恶意软件感染。
