PACTF_2018: Spill Your Heart Out

Category: Lovelace Points: 65 Description:

I was playing this lottery. Which number is going to win next time? If only you could see into the future…

Write-up

Slightly more challenging challenge, this one involved breaking java.util.Random by bruteforcing the possible seeds given the initial two Integers. A very good resource on this can be found here.

In the case of this challenge, a Java solution will be used to get our third number.

# javac Solve.java && java Solve
-632232200

Therefore, the flag is -632232200.
