Magnet Forensics Virtual CTF 2024 – Android Challenges

Warm Up
What Southern state’s sports team did Rocco search up? (STATE ONLY)

In Axiom > Web Related > Chrome Keyword Search Terms, “ragin cajuns football roster” is on the list.  In America, we consider football a sport.  (We also consider soccer a sport, but use the proper names.)

Google “ragin cajuns”, and discover they’re from Louisiana

Flag: Louisiana


Can you Handle this
What was Rocco’s Twitter account name?

Under Axiom > Social Networking > Twitter Users > saw “rocco” in one of the User Names and used good old fashioned guessing

Not to be basic but…
What is the default Internet Browser?

Again ALEAPP is our friend here. ALEAPP > Browser Cache

Just 2 browsers listed and limited at 3 attempts.  I like those odds.  Given that it’s an Android phone, let’s start with the obvious.

Flag: Chrome


Survival Mode Activated
What conference did Rocco show interest in?

Let’s head back to AXIOM > Google search terms

“Survival” + “conference”.  I think I see a good match.

Not so popular
How many messages were sent from Rocco in Twitter Direct Messages?

Checked ALEAPP > FCM_Twitter_DM for info. That returns “0”. That’s not right, is it?
Hopping back to AXIOM > Social Networking > Twitter Direct Messages >
We find evidence that shows Rocco sent a message and has Recipient ID of 1719897971716685824

Sort by sender id and count with my fingers to find 16 messages.

You can never be too ready
How many additional survival tips were provided in the $9 book Rocco was looking into?

Tag you’re it!
What city was the user in when they identified an AirTag on them?

While browsing around earlier in ALEAPP, I noticed “AirTag” while scrolling. Let’s go see what info we can get from there.
ALEAPP > Airtag Detection > Android Airtag Scans > coordinates to maps

Flag: Windsor


R-E-J-E-C-T-E-D Rejected
When was the last shutdown that was initiated by Rocco? (YYYY-MM-DD HH:MM:SS) UTC 24 hour time.

So Salty!
What is the handle of the person who is talking about how upset they are with Rocco?

AXIOM > Entered search term “salty” > Twitter search

AuthorID is 1739363969809227776
But what do I do with that? Didn’t see anything jumping out in AXIOM.

Found a couple of sites that claim to convert IDs to usernames. They didn’t.
In the end, I searched Twitter for the tweet itself
