Reverse: Old hits

Using Ghidra, as well as gdb, analyze the old-hits/support/old-hits binary and obtain the secret information. The program generates a random value and asks you to guess another value calculated based on the aforementioned one.

If you're having difficulties solving this exercise, go through this reading material.

Note: The following error can occur when running the executable if you don't have libcrypto.so.1.1 installed on your system:

./old-hits: error while loading shared libraries: libcrypto.so.1.1: cannot open shared object file: No such file or directory

To install libcrypto.so.1.1 run the following commands:

wget http://nz2.archive.ubuntu.com/ubuntu/pool/main/o/openssl/libssl1.1_1.1.1f-1ubuntu2_amd64.deb
sudo dpkg -i libssl1.1_1.1.1f-1ubuntu2_amd64.deb
rm libssl1.1_1.1.1f-1ubuntu2_amd64.deb
