Cacador (Portugese for hunter) is tool for extracting common indicators of compromise from a block of text.
The easiest way to get cacador is to download the latest release for your platform. Good? Great.
- Install golang
go get github.com/sroberts/cacador- Compile with
go build
Run with ./cacador. It accepts text from stdin and writes a JSON blob of IOCs to stdout. For example cat text.txt | ./cacador | import where text is some IOC rich text and import pushes your new IOCs into your threat management system.
Cacador does recognize two command line flags:
-
-comment="Foo"which makes it possible to leave a note as metadata. -
-tags="Foo, bar, baz"which adds tags.
- Install goreleaser via
go get github.com/goreleaser/goreleaser. - Push your branch to GitHub.
- Tag it via
git tag -a v1.0.3 -m "Release 1.0.3 - Minor bugfix edition." - Push the tag to GitHub via
git push origin v1.0.3 - Ensure you have a
GITHUB_TOKENenv var set. - Run
goreleaser.
Other tools for doing indicator extraction are pretty awesome (like armbues/ioc_parser or sroberts/jager), but what's nice about cacador is you can compile it and put it in your path and use it for Unix style workflows with pipes and things. Also it's super fast and was a good excuse to learn Go.
