Robotic Infiltration Writeup
Cyber Apocalypse 2021
Solved by : thewhiteh4t
- We got a
capture.bag
file in this one - The challenge mentions ROS which leads to a utility called
rosbag
- rosbag can be used to play this bag file
- Installation and tutorials are given in ros wiki : http://wiki.ros.org/Documentation
- The challenge mentions
rebuild plan for facility
- after some poking around we saw rosbag comes with another utility known as
rviz
- rviz can be used for 3d visualization of bag files
Step 1 : Start roscore
Step 2 : Play bag file
$ rosbag play capture.bag
Step 3 : Launch rviz
$ rosrun rviz rviz
- Now all we had to do was tweak things in rviz a little to improve visibility and eventually we spotted the flag
- After some play and pause action we got the full flag
