Khulnasoft Analyze SDK

Khulnasoft SDK

The SDK wraps Khulnasoft Analyze API 2.0 (View full API documentation)

Currently, the following options are available in the SDK:

• Analyze by file
• Analyze by SHA256
• Analyze Url
• Index by file
• Index by SHA256
• Get Latest Analysis
• Account and file related samples
• Code reuse and Metadata
• IOCs, Dynamic TTPs and Capabilities
• Strings related samples
• Search a family
• Ingest an alert from any source
• Ingest a raw email alert (.msg or .eml file)

Installation

pip install khulnasoft-analyze-sdk

Using Khulnasoft SDK

Set global api key

Before using the SDK functionality we should set the api key:

    api.set_global_api('<api_key>')

Analyze By File

analysis = FileAnalysis(file_path=<file_path>,
                    dynamic_unpacking=<force_dynamic_unpacking>, # optional
                    static_unpacking=<force_static_unpacking>)   # optional
analysis.send(wait=True) 
result = analysis.result()

Analyze By SHA256

analysis = FileAnalysis(file_hash=<file_sha256>)
analysis.send(wait=True)
result = analysis.result()
