  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
• Creates a copy of itself;
• Attempts to interact with an Alternate Data Stream (ADS);
• Anomalous binary characteristics. This is a way of hiding virus’ code from antiviruses and virus’ analysts.
