About
Badcapt is a project inspired by Bad Packets' work and the Remote Identification of Port Scan Toolchains paper by Vincent Ghiette, Norbert Blenn, Christian Doerr.
It will try to detect malicious packets and export them to the Elastic storage or output to the stdout for your further processing.
Install
The app is built on top of gopacket
package which provides C bindings for the
libpcap
, so you should have libpcap-dev
package installed first.
go get github.com/ilyaglow/badcapt/cmd/badcapt
Also you can use the docker image (see below on how to use it):
docker build -t badcapt https://github.com/ilyaglow/badcapt.git
or
docker pull ilyaglow/badcapt
Usage
./badcapt -h
Usage of badcapt:
-e string
Elasticsearch URL (optional)
-i string
Interface name to listen
If no Elasticsearch URL provided, badcapt will simply output records to the screen.
To use the dockerized version you must run it with --net=host
switch:
docker run -d --net=host ilyaglow/badcapt -i eth0
You can also take a look at the badsearch companion script for the Elasticsearch: it dumps all records in the database for the last 24 hours.
