TrickBot is a malware infection commonly installed via malicious phishing emails or other malware. When installed, TrickBot will quietly run on a victim’s computer while it downloads other modules to perform different tasks. New features added to TrickBot include injecting its DLL into the legitimate Windows wermgr.exe (Windows Problem Reporting) executable directly from memory using code from the ‘MemoryModule’ project. The TrickBot gang is still chugging along, as shown by the release of the TrickBot malware’s hundredth build.
