QUESTION
I'm trying to configure Zeek in order to store files (every file) on disc, but without any success. OS I'm using: Debian 10.
What I did so far:
I've installed this module: https://github.com/hosom/file-extraction (even after following this site https://www.ericooi.com/zeekurity-zen-part-vi-zeek-file-analysis-framework, I couldn't put it to work).
I've loaded frameworks/files/extract-all-files script.
I can see the scripts are loaded, after checking loaded_scripts.log
I'm a beginner on Zeek, and I'd like to learn how to enable zeek to save files (that is traversing the network) and store on disk. The only sort of files that is being stored: HTTP and SSL.
I'm sure I'm making many mistakes, but I'm not able to find the correct way.
EDIT
Zeek version I'm using: zeek version 4.1.0-dev.545.
I'm processing traffic. I haven't tried anything with pcap, but I'll try what you've suggested with "zeek -r the.pcap policy/scripts/frameworks/files/extract-all-files.zeek".
On Zeek server, I've installed (in order to test) a FTP and a HTTP server. At html folder, I created a pdf file (so I can download it later). I've put two files (a pdf and a plain text file), and I downloaded (using a browser on another computer in the local network) that pdf file. As a result, I can see (looking at ftp.log and http.log) all the files that I mentioned, but those files aren't stored on disc. My doubt is: should they be stored by Zeek?
...ANSWER
Answered 2021-May-12 at 19:20A common problem when running traffic through Zeek is that packets may have invalid checksums. Zeek by default skips such packets, so the net result is missing logs/files/artifacts that the user expects to be there. Often those invalid checksums are caused by checksum offloading, where the packet capture process grabs transmitted packets before the NIC had a chance to fix the checksums.
Zeek normally warns when it encounters invalid checksums -- look for the something resembling the following on stderr, or in reporter.log:
Your trace file likely has invalid TCP checksums, most likely from NIC checksum offloading. By default, packets with invalid checksums are discarded by Zeek unless using the -C command-line option or toggling the 'ignore_checksums' variable.
(This is from find-checksum-offloading.zeek, which is included in Zeek's default configuration.)
You have many options here. You can:
- run Zeek with
-C, as per the above - say
redef ignore_checksums=T;in a script (usually local.zeek) - add the redef at the command line:
zeek -r the.pcap ... ignore_checksums=T - fix the checksums in the pcap, e.g. with
tcprewrite -C -i input.pcap -o fixed.pcap(tcprewriteships with tcpreplay) -- this is best if others will consume your pcap too.
QUESTION
I'm trying to send the same log flow to two different elasticsearch indexes, because of users with different roles each index.
I use a file for destination too. Here is a sample:
...ANSWER
Answered 2021-Feb-12 at 15:21You can check the exact error message in the journal logs, as it is suggested by systemctl:
See "systemctl status syslog-ng.service" and "journalctl -xe" for details.
Alternatively, you can start syslog-ng in the foreground:
$ syslog-ng -F --stderr
You probably have a persist-name collision due to the matching elasticsearch-http() URLs. Please try adding the persist-name() option with 2 unique names, for example:
QUESTION
I was trying to incorporate Reddit into my bot but every time I run it keeps on giving me this error.

My Code:
...ANSWER
Answered 2021-Feb-01 at 17:12So your problem is that you are mixing up the diffrence between bot and client. Those are to diffrent things.
A bot is simpler, it just recivies commands from you and handles them. Meaning it does something. If you want to write in the chat and do more things you need a client.
Besides that you can't create a Bot like that:
client = commands.Bot(command_prefix=bot_prefix)
The right way would be: bot = Bot(command_prefix='$') since you have already imported bot.
The way to go for you would be to stick with the client and instead of commands use:

QUESTION
I try to use GeoIp functionality in Bro/Zeek.
From the official Zeek Documentation:
If you see an error message similar to “Failed to open GeoIP location database”, then you may need to either rename or move your GeoIP location database file. If the mmdb_dir value is set to a directory pathname (it is not set by default), then Zeek looks for location database files in that directory.
Ok, mmdb_dir is not set:

QUESTION
I'm testing Zeek/Bro capabilities in terms of detecting different types of steganography. After working with the ICMP protocol now I am trying to inspect the TCP protocol. I want to detect if the reserved bits in TCP are changed with help of TCP events. Unfortunately without success.
Is it possible to inspect TCP reserved bits with Zeek?
...ANSWER
Answered 2020-Mar-24 at 01:33Not out of the box, no. One way to add it would be to expand the TCP_Flags class in your local build so it captures the TCP header's th_x2 field bits as well. Then, use the tcp_packet event, which reports the flags.
This would be quite slow, though, as it'd be packet-level analysis.

I am looking for the list of services that bro/zeek identifies in conn.log. But I am unable to find out exactly how many services Bro identifies. Where can I get the correct script le, source code or documentation where I can get the list of services that Bro detects?

...ANSWER
Answered 2019-May-28 at 05:24The answer to this question is a bit complex, because it depends on the set of protocol analyzers present on your system and how they are configured (i.e., how/whether Zeek may select them for individual connections).
That said, this list defines the set of supported analyzers. There may be more if you install additional ones on your system via the package manager.
The nitty-gritty details are spelled out in the original paper.

Install zeek
You can use zeek like any standard Python library. You will need to make sure that you have a development environment consisting of a Python distribution including header files, a compiler, pip, and git installed. Make sure that your pip, setuptools, and wheel are up to date. When using pip it is generally recommended to install packages in a virtual environment to avoid changes to the system.
