SNMP Packets

Another problem from ACSC5. You’ve been able to get on a router and capture some traffic in an effort to map out the the corporate network. Your intelligence team has told you that your target device has an IP address of 172.16.58.47 but no one knows that actual location of it. Examine the network traffic and see if you can figure out the location of that device.

Slow Mover

network forensics

Another problem from the 5th annual Army Cyber Skills Challenge.  The problem is called slow_mover and can be found here.

Problem
Your boss just handed you this PCAP that one of your network sensors captured. He’s positive that there is something fishy going on here but has no clue what it is.

find_the_stack2

The is a follow-on to the first find_the_stack problem from ACSC5.  This was originally supposed to be the third one in a series of challenges based on this problem but I had some problems with number two so this became number two.

find_the_stack

stacks

This is the first of what will hopefully be many walk-throughs from various CTF competitions I’ve competed/worked on.  This first challenge is a simple one that I created for the 5th annual Army Cyber Skills Challenge.
