Defender ATP and PowerBI

Maybe, you don’t want management in the ATP portal, even though it’s configurable via roles, and maybe they don’t want to be there.

One thing I know is that most managers loves numbers, so why not provide them with a PowerBI report.

You can perfectly use cloud based option and there is an app for Windows Defender ATP already there for you to use.

Configure your connector and you’re all good to go

The dasboard looks like the following picture

With the many different tiles you, or your manager, can dig deeper in to events like in this following example with alert status

It’s also possible to filter data based on who a case was assigned to, who resolved the case etc.

If you have a PowerBI Pro account, you could subscribe to get scheduled reports.

You can also to quick filter

This is an easy win for your manager

CTF, Capture The Flag

CTF, Capture the Flag is a known form of a game mode for various games like Paintball, laser games and Computer games, but it’s also used in Computer Security.

Capture the Flag is a really good way of enhancing your Security skills, it starts with a few clues and quests you must solve to retrieve the flag for the challenge. These are named as Jeopardy-style CTF. They are often devided into different types of challenges i.e.:

  • Cryptography
  • Web
  • Forensics
  • Binary Exploitation
  • Reversing
  • Networking

There are also modes for CTF called Attack-Defense, where the teams have to defend their own network or machine and att the same time attack the opponents. There is also a version like one team is defending and the other one is attacking, a Blue Team – Red Team approach.  Blue Team defends and tries to find out how and when the Red Team makes their way to get the Flag.

It’s for everyone with a interest in cyber security.

Qualify for bigger events

Some CTF’s are qualifiers for bigger CTF events, so get going and solve the challenges!

Example challenge from (https://capturetheflag.withgoogle.com):

This CTF has beginner challenges (which I can recommend if you’re new to this).

Amongst the beginner challenges we have the following one.

CTF challenge

This challenge want us to find the flag which will look like “CTF{xxxxxx}” by using the clues in the text and the file which we are able to download.

We download the file (Attachment) and extract the content

The clue from the challenge indicates it’s something fishy with this .ico file.

Tha the initial view, it looks alright.

Let’s use binwalk which is a tool for searching binary images for embedded files and executable code to see if there is something hidden inside.

It looks like we’re getting somewhere, it seems to be a zip archive.

Let’s try to list the content with 7zip

Works! Next step would be to unpack the content in our hunt for the flag

We have extracted our files

And we now have the flag!

We enter it on the website and the challenge is completed and can start the next challenge…

Where to start?
