The WildFire public cloud now unpacks and deobfuscates
files that have been encoded using custom and open source file compression
or packing tools. This provides improved coverage by analyzing files
that might have previously dropped as a result of code obfuscation.
No additional configuration is required to analyze files using dynamic
unpacking; it is automatically performed based on file characteristics
detected by WildFire.
Additional information about dynamic unpacking:
WildFire analysis results for files that are decompressed
using dynamic unpacking are shown under the static analysis heading
of the WildFire Analysis Report. The following example shows two
new behaviors associated with dynamic unpacking.
Dynamic unpacking does not have an analysis platform number,
as it uses a combination of static and dynamic analysis.
Dynamic unpacking behaviors are listed under the Suspicious
File Properties heading of the WildFire Analysis Report.
