Takajo Logō

[ English ] | [日本語]

About Takajō

Takajō (鷹匠), created by Yamato Security, is a fast forensics analyzer for Hayabusa results written in Nim. Takajō means "Falconer" in Japanese and was chosen as it analyzes Hayabusa's "catches" (results).

Features

  • Written in Nim so it is very easy to program, memory safe, as fast as native C code and works as a single standalone binary on any OS.
  • Print the process trees of a malicious processes.
  • Split up CSV and JSONL timelines.
  • Extracting IP addresses, domains, hashes etc... to be used with VirusTotal lookups
  • VirusTotal lookups of domains, hashes and IP addresses.
  • List up .evtx files that cannot be detected yet.
  • Visualize TTPs with heatmaps in MITRE ATT&CK Navigator.
  • Stacking command lines, DNS requests, logons, processes, services, tasks, etc...
  • Timelines for logons, USB usage, suspicious processes, tasks, etc...
  • HTML summary reports
  • Many more!

Downloads

Please download the latest stable version of Takajo with compiled binaries or compile the source code from the Releases page.

Note: we provide release binaries for 64-bit Windows and Intel and Arm-based macOS but not Linux because it is difficult to provide MUSL binaries for Linux at the moment.

Git cloning

You can git clone the repository with the following command and compile binary from source code:

Warning: The main branch of the repository is for development purposes so you may be able to access new features not yet officially released, however, there may be bugs so consider it unstable.

git clone https://github.com/Yamato-Security/takajo.git

Advanced: Compiling From Source (Optional)
