![]() The malware can detect this two ways, either by requesting the Hive key or using the GetAdapterInfo API. This address is often stored in the registry at (HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\\0000\NetworkAddress). MAC address detection: Virtual environments such as VMware or VirtualBox use known MAC addresses.Malware can perform several basic checks: Sandboxes are an effective tool to quickly detect and understand malware however, it is relatively trivial for malware to detect a sandbox if it is not hardened. Malware can use a technique like RunPE (which runs another process of itself in memory), to evade antivirus software, a sandbox or an analyst. Some malware techniques are common to these three categories. For example, spotting monitoring tools such as Process Explorer or Wireshark, as well as some process-monitoring tricks or packers, to avoid reverse engineering. Anti-analyst: Used to detect and fool malware analysts.Anti-sandbox: Used to detect automatic analysis and avoid engines that report on the behavior of malware.Anti-security tools: Used to avoid detection by antivirus, firewall, and other tools that protect the environment.We can classify these techniques into three categories: Malware can use several mechanisms to avoid detection and analysis. Antimalware tools are sometimes outdated, and sandboxes can easily be detected due to misconfiguration. In addition, organizations do not always follow best practices. However, attackers understand and monitor the operations of security tools. The IT security market has matured and security tools and applications are today more efficient. If malware is detected quickly, it has little time to steal data or to maximize its impact. This post offers an overview of the mechanisms used by malware to evade detection. Their success depends on a threat’s remaining undetected and avoiding sandbox analysis, antivirus efforts, or malware analysts. Many malware authors spend a great deal of time and effort to develop complex code.
