![]() Trend Micro XGen™ security provides a cross-generational blend of threat defense techniques to protect systems from all types of threats, including ransomware and cryptocurrency-mining malware. The Trend Micro™ Deep Discovery™solution has an email inspection layer that can protect enterprises by detecting malicious attachments and URLs. ![]() Trend Micro endpoint solutions such as the Smart Protection Suites and Worry-Free Business Security solutions can protect users and businesses from threats by detecting malicious files and messages as well as blocking all related malicious URLs. The evolving aspect of cryptocurrency mining malware - constantly adding evasion techniques - means that powerful security tools are often needed to defend users from these kinds of threats. ![]() This indicates that the threat actors behind it are exerting extra effort to ensure that their creation remains as stealthy as possible. One notable aspect of the malware is that it uses the popular custom Windows Installer builder WiX as a packer, most likely as an additional anti-detection layer. It then deletes every file under its installation directory and removes any trace of installation in the system. The next part of the installation process involves creating copies of the kernel file ntdll.dll and the Windows USER component user32.dll in %AppData%\Roaming\Microsoft\Windows\Template\FileZilla Server\.cmD <- self-delete command-line script bin – The encrypted, UPX-packed and Delphi-compiled cryptocurrency mining module.ocx – The loader module responsible for decrypting and installing the cryptocurrency mining module.Unpacking icon.ico reveals two addition files contained within it: ico – A password protected zip file posing as an icon file.exe – An unzipping tool used for another file dropped in the directory, icon.ico.bat – A script file used to terminate a list of antimalware processes that are currently running.This directory will contain various files that are used as part of its process: Upon installation of the sample we analyzed, we found that it will install itself in the directory % AppData%\Roaming\Microsoft\Windows\Template\FileZilla Server, which will be created if it isn’t already present in the user’s machine. Using a real Windows component makes it look less suspicious and potentially allows it to bypass certain security filters. The malware arrives on the victim’s machine as a Windows Installer MSI file, which is notable because Windows Installer is a legitimate application used to install software.
