Prenote: As all of these challenges were similar, we decided to combine these under one page.

Flag 1

nmap all ports to see port 4994 is open, just nc to it to get flag

flag :zh3r0{pr05_d0_full_sc4n5}

Flag 2

Going back to port 324 (ftp)

the flag is in .../.../.flag

flag: zh3r0{You_know_your_shit}

Flag 3

curling port 22 robots.txt gives you a string in base58, decode to get /clue3349203.txt, curl that to get a lot of jsfuck, decode that to get an employee id, and then use that on port 4994 to get the flag

flag: zh3r0{y0ur_b0nu5_i5_p4id}

Flag 4

if we scan port 324, we can see it is an ftp server, which allows anonymous login.

ls -a ing gives us a ... dir (wow thanks hq), and then cding into it and ls -a ing again gives us a .stayhidden file. reading this gives us another employee id, which we can use to login to port 4994 again.

flag: zh3r0{y0ur_s4l4ry_wa5_cr3dit3d}

Flag 5

nmap, see http port on port 22, curl it to get flag
