How to use deepbluecli

I find Bushy Evergreen in the train station as my badge indicated I would:. I had to look at the man page for ed. There are two commands to quit:. So I enter q into the terminal and hit enter, and I get success:. Last year, I performed a similar analysis by hand. I download it from GitHub and unzip it to where I can use it.

The output is a series of alerts summarizing potential attacks detected in the event log data. There are 12 alerts indicating Password Spray Attacks. A Password Spray attack is when the attacker tries a few very common passwords on all the accounts, rather than a typical brute force where they try huge wordlists of potential passwords against a single user.

These alerts look like:. Each one looks like this:. Each have a different username, and all but one had 77 total logon failures. Given that supatree has multiple admin logons, and one less failed logon attempt than everyone else, it seems his account was likely the one compromised. Submitting that name solves the challenge.

Objective Link: Security. Pepper is forcing me to learn ed. Even the hint is ugly. Please help me just quit the grinchy thing. Going into the terminal presents the challenge That Pepper LOLs and rolls her eyes, sends mocking looks my way. I need to exit, run - get out! Your challenge is to help this elf escape this blasted tool. Q Quits ed unconditionally. This is similar to the q command, except that unwritten changes are discarded without warning. You did it!

I covered RITA in for toolsmithand have really enjoyed its evolution. I found the answer to the related Kringlecon challenge with the current iteration of RITA in two steps.

It does take a bit more time to query the running event log service, but no less effective. Be sure to read all the GitHub documentation but note the following detection categories, with multiple detections per:. I'll run through a number of the examples via the sample EVTX files provided via the project download and share with you a variety of results. We'll also crank out some output options based on said results.

DeepBlueCLI: Powershell Threat Hunting

Also read the project documentation to ensure proper logging configurations for your target systems, this is quite important to ensure effective coverage and positive results. Finally, let's generate a bit of proper output.

Eric and team really have built a useful and efficent framework that has been added to my preferred arsenal thanks to Kringlecon. Obviously, you'll want to give DeepBlueCLI a good look, as well as the others mentioned in the intro, and above all else, even if only a best effort, give Kringlecon 3 a go next year.

It really is a blast, you'll learn a ton. Cheers…until next time. Log In or Sign Up for Free! Join us at SANS!

Those among you who participated in the SANS Holiday Hack Challengealso known as Kringlecon 2this holiday season may have found themselves exposed to new tools or the opportunity to utilize one or two that had not hit your radar prior. While others such as EQL and stoQ an automation framework that helps to simplify the mundane and repetitive tasks an analyst is required to do come to light, I also reveled in a chance to use RITA for Zeek logs analysis.

I covered RITA in for toolsmithand have really enjoyed its evolution. I found the answer to the related Kringlecon challenge with the current iteration of RITA in two steps. It does take a bit more time to query the running event log service, but no less effective. Be sure to read all the GitHub documentation but note the following detection categories, with multiple detections per:. Note: Run PowerShell as admin for best the required effect.

Also be sure to review the Set-ExecutionPolicy Readme if you receive a running scripts is disabled on this system error. Also read the project documentation to ensure proper logging configurations for your target systems, this is quite important to ensure effective coverage and positive results.
