Tangentially relevant: the TryHackMe Advent of Cyber side quest this year[0] featured a pair of ROS nodes that we had to attack.
I had never encountered ROS before but, having scoured the documentation to figure out how to write a malicious node[1] and exfil data via `rostopic`, it sure felt great not to have to use ROS professionally, and to know I was probably never going to encounter it again.
