# A Cube and a Palindrome
For this challenge, we were given a file with nbin extension.Quick search for nbin on google showed that it was a plugin for Nessus.
I initially thought I had to import the plugin through the Nessus GUI.However, this is not the case, and the nbin file can be ran through the console.When you install Nessus, you are given a binary /opt/nessus/bin/nasl.This binary can be used to run the nbin binary file.
`/opt/nessus/bin/nasl -VV timestamp.nbin`
When running the binary, you will be asked to input a time in epoch.I tried entering the current epoch time, which returned "To soon!"From there, I manually did a binary search to find the right time.
The correct time seems to change over time, but after several random guess, I was luckily able to get the flag.
The solution seems to be guessy, but I checked the official write-ups for the challenge and it was doing the same thing (except it was using a script instead).
