Solution

As usual, download the downloadable file and unzip it.

After unzip that zip file, we see 2 files: omega-one and output.txt.

omega-one: 64-bit ELF executable

output.txt: A list of name??

Then we’ll need to use any reverse engineering tools, like Ghidra.

In the FUN_00100b4c or main function, we see there are some weird strings, and those strings matches the list of names in output.txt.

Let’s compare them one by one!!
