Laika is an object scanner and intrusion detection system that strives to achieve the following goals:

• Scalable
  • Work across multiple systems
  • High volume of input from many sources
• Flexible
  • Modular architecture
  • Highly configurable dispatching and dispositioning logic
  • Tactical code insertion (without needing restart)
• Verbose
  • Generate more metadata than you know what to do with

Each scan does three main actions on each object:

• Explode children

  Some objects are archives, some are wrappers, and others are obfuscators. Whatever the case may be, find children objects that should be scanned recursively by exploding them out.

• Mark flags

  Flags provide a means for dispositioning objects and for pivoting on future analysis.

• Add metadata

  Discover as much information describing the object for future analysis.

Laika is composed of the following pieces:

• Framework (laika.py)

  This is the core of Laika BOSS. It includes the object model and the dispatching logic.

• laikad

  This piece contains the code for running Laika as a deamonized, networked service using the ZeroMQ broker.

• cloudscan

  A command-line client for sending a local system file to a running service instance of Laika (laikad).

• modules

  The scan itself is composed of the running of modules. Each module is its own program that focuses on a particular sub-component of the overall file analysis.

Laika BOSS has been tested on the latest versions of CentOS and Ubuntu LTS

We recommend using installing jq to parse Laika output.

From the directory containing the framework code, you may run the standalone scanner, laika.py against any file you choose. If you move this file from this directory you'll have to specify various config locations. By default it uses the configurations in the ./etc directory.
