A Zeek JPEG File Analyzer Package
This package implements:
- JPEG
TLDR!
If you have zkg and you have already run...
zkg autoconfig
... then you can install this package as so:
sudo zkg install zeek-jpeg
Now in any Zeek script, just load the plugin and it "just works":
@load Zeek/JPEG
New events for this plugin are found in events.bif.
Building and Installing
This plugin can be built with:
./configure --zeek-dist=/your/zeek/src/dir
make
sudo make install
If you have zkg and you have already ran...
zkg autoconfig
... then you can install this package as so:
sudo zkg install zeek-jpeg
Using JPEG
Once installed, this plugin can be loaded with the following Zeek script:
@load Zeek/JPEG
event file_jpeg_marker(f: fa_file, m: Zeek::JPEGMarker)
{
print m;
}
You can download the example PCAP file http_with_jpegs.cap from the Wireshark project.
Here is what the output will look like:
% zeek -r pcaps/http_with_jpegs.cap jpeg.zeek
