Windows Portable Executable Attributes
This section lists file attributes found within family samples. These attributes are extracted
from the files’ Windows PE (Portable Executable) specification and various system flags. Portable
Executable Attributes give malware researchers insight into a file’s functionality, executable details,
platform and runtime environment.
Windows PE Version Information
This section displays values and attributes that have been set in the Windows file version
information data structure for samples within this family. To mislead users, malware actors often add
fake version information mimicking legitimate software.
Files Modified
This section lists files that were created, modified, moved and/or deleted by samples in this
family. File system activity can provide valuable insight into how malware functions on the operating
system.

Registry Modifications
This section lists registry keys and values that were created, modified and/or deleted by
samples in this family. Windows Registry activity can provide valuable insight into malware
functionality. Additionally, malware often creates registry values to allow itself to automatically
start and indefinitely persist after an initial infection has compromised the system.
Windows API Usage
This section lists Windows API calls that are used by the samples in this family. Windows API
usage analysis is a valuable tool that can help identify malicious activity, such as keylogging,
security privilege escalation, data encryption, data exfiltration, interference with antivirus software,
and network request manipulation.
