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.
File doesn't have "Rich" header
File doesn't have exports table
File is 32-bit executable
File is either console or GUI application
File is GUI application (IMAGE_SUBSYSTEM_WINDOWS_GUI)
File is Native application (NOT .NET application)
File is not packed
IMAGE_FILE_DLL is not set inside PE header (Executable)
IMAGE_FILE_EXECUTABLE_IMAGE is set inside PE header (Executable Image)
File Icons
File Icons
This section displays icon resources found within family samples. Malware often replicates
icons commonly associated with legitimate software to mislead users into believing the malware is
safe.
Windows PE Version Information
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.
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.
During analysis, EnigmaSoft breaks file samples into logical blocks for classification and
comparison with other samples. Blocks can be used to generate malware detection rules and to group file
samples into families based on shared source code, functionality and other distinguishing attributes and
characteristics. This section lists a summary of this block data, as well as its classification by
EnigmaSoft. A visual representation of the block data is also displayed, where available.
This section lists other families that share similarities with this family, based on
EnigmaSoft’s analysis. Many malware families are created from the same malware toolkits and use the same
packing and encryption techniques but uniquely extend functionality. Similar families may also share
source code, attributes, icons, subcomponents, compromised and/or invalid digital signatures, and
network characteristics. Researchers leverage these similarities to rapidly and effectively triage file
samples and extend malware detection rules.

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.

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.
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.

Shell Command Execution
This section lists Windows shell commands that are run by the samples in this family. Windows
Shell commands are often leveraged by malware for nefarious purposes and can be used to elevate security
privileges, download and launch other malware, exploit vulnerabilities, collect and exfiltrate data,
and hide malicious activity.
