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.
Digital Signatures
This section lists digital signatures that are attached to samples within this family. When
analyzing and verifying digital signatures, it is important to confirm that the signature’s root
authority is a well-known and trustworthy entity and that the status of the signature is good. Malware
is often signed with non-trustworthy “Self Signed” digital signatures (which can be easily created by a
malware author with no verification). Malware may also be signed by legitimate signatures that have an
invalid status, and by signatures from questionable root authorities with fake or misleading “Signer”
names.
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.

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.
