Feature documentation

Malware analysis

Polichombr provides an engine to automate the analysis tasks by identifying points of interest inside the malicious binary, and providing them both on a web interface and inside the analyst's tools via an API.

Plugins / tasks

Analysis tasks are loaded from the app/controllers/tasks directory, and must inherit from the Task object. In particular, several tasks are already implemented:

• AnalyzeIt, a ruby script based on metasm, wich is used to identify interesting points in the binary. The goal is to help the analyst by giving hints about where to start. For example, we try to identify crypto loops, functions wich calls sensitive API (file, process, network, ...)

• Peinfo : We load the PE metadata with the peinfo library.

• Strings : extract ASCII and Unicode strings

Signatures

We use several signature models to classify malware:

• Yara
• imphash
• Machoc

Machoc

Machoc is a CFG-based algorithm to classify malware. For more informations, please refer to the following documentation:

• Formal description
• Originating paper

IDA Collaboration: Skelenox

This is an IDAPython plugin, wich is used to synchronize the names and comments with the knowledge base, and with other users database
