Daily "Pace Car" Problems (Optional Extra Credit problems: do 16 to skip Project 3)

I'll try to release an interesting topical problem each class. These help you keep pace with the mastery tasks.


PCP2: (little tougher) findtheflag

PCP3: (HARD) Solve the February 8th "Intro Buffer Overflow" Imaginary CTF problem (Problem files with the latest glibc and patched etc can be found HERE)

PCP4: (IMPORTANT) Mastery A and B in one: Learn To See/C

PCP5: A classic crackme crackme

PCP6: Write a crackme for your fellow students and solve one student crackme.

PCP7: Flag Checker

PCP8: Solve the first of the 0-hero problems at https://sec.prof.ninja/challenge/, you'll just say "got it" in the discord, maybe your pwntools script.

PCP9: LIVE ONE! hackme running at nc 1337 (patched version with libraries: Hackme.zip)

PCP10: LIVE ONE! decaf64 in args.zip running at nc 1338

PCP11: LIVE ONE! decaf also in args.zip running at nc 1339

PCP12: Solve ROPEmporium callme32 you can say "got it" with spoilered script or some other proof.

PCP13: LIVE ONE! pltme running at nc 1340

PCP14: Help day: Pick any PCP problem, or pwn problem from the class, that was the hardest for you when you first attempted it (it might be easier for you now). Make a "write-up" that is designed to help someone else facing that same problem. Share the write-up, make the world a little more beautiful.

PCP15: LIVE ONE! pltmeHARDCORE running at nc 1341

PCP16: LIVE ONE! fmtstr.zip running at nc 1342

PCP17: LIVE ONE! got.zip running at nc 1343

PCP18: formatz is the binary for this writeup: https://ctftime.org/writeup/26750 use the write-up to actually exploit this and the libc is libc.so.6

PCP19: LIVE ONE! srop from Rooters 2019 is the binary for this writeup: write-up here nc 1345

PCP20: RESET/SIMPLE ONE! Run either of the two scripts from class using gdb with pwndbg and after a malloc vis the heap, take a screenshot and share.

PCP21: RESET #2 Use the playground code from class and generate a leak using Use-After-Free. Use pwndbg to identify what you leaked. Extra points if it is a glibc leak.

PCP22: LIVE ONE! tcache.zip is running at nc 1344

PCP23: LIVE ONE! www (same source different glibc) is running at nc 1346 but compiled to Ubuntu GLIBC 2.35-0ubuntu3.1
