OPERATORS

[ ACTIVE CHALLENGES ]

File Descriptor

Understand Linux file descriptors and how stdin/stdout/stderr work at the OS level.

Buffer Overflow

Classic stack-based buffer overflow - overwrite a local variable to spawn a shell.

Predictable RNG

The PRNG is seeded with a fixed value - predict the output before it runs.

Exploit a flawed checksum function to produce a deliberate hash collision.

Assembly Shellcode

Write raw x86-64 shellcode to open, read, and print a flag file from the server.

Exploit a format string + misused scanf to overwrite a GOT entry and bypass login.

Exploit heap use-after-free to hijack a C++ vtable pointer and call give_shell().

Interpreter Exploit

Exploit a Brainfuck interpreter with arbitrary read/write to leak libc base and get a shell.
