Been playing with Kali DirBuster & am approaching 500 million pings out a server brute force exploring the 4th level of its directory structure to see where looks interesting & to go back to specifically visit 😎 .
But it takes forever lol ... even at 3000 pings a second.
They have predicable file naming, so once have the structure, we also have all the file names in the next level (yea, they didnt think about that ... oops 😂 )
