Magnet Weekly CTF — Week 6

Part 1

The first part of the question involved finding a dependency for Hadoop that failed to install and getting the error number associated with that error.

Can’t be that easy right?

Part 2

This part was a bit more tricky:

  1. Closely related dependency: Alright, well Java 7 failed, so were there any other java installs that worked? Yes, looking in the log right after the 404 error, looks like Java 8 installed properly.
  2. Where did it land? This was probably the crux of the matter, and it took me the longest to confirm I was in the right place, but eventually I found the following export lines in the .bash_history file:
The three largest files in the Java 8 directory
readelf --syms unpack200 | grep 404
