LakeCTF 2026 Aftermovie
Niklas HeringerWhat's your favorite error in labs that took you hours to fix?
A few of my examples from this week:
- my VPN tunnel was silently dropping large packets (MTU)
- LinPEAS was screaming because /bin/sh is dash, not bash
- I killed my nmap scan trying to close a tmux pane
wrote it all up so you don't have to suffer the same way
also: netcat is just a pipe. that's it. people using nc -lvnp 4444 often seem to forget what nc really does.

In the past weeks, the pwn.college Dynamic Allocator Misuse module taught me many practical concepts I have long known from theory:
Use-after-free, double-free, tcache internals, LIFO reuse, tcache poisoning, arbitrary read, fake chunks, safe-linking, whitespace-armored addresses, and partial secret corruption.
Knowing theory is good, but experiencing those concepts in practice is priceless.
Thank you, @pwn.college!

Finished the pwn.college Yellow belt Dynamic Allocator Misuse - 4 weeks of type-2 fun.
Onward to greatness and my Yellow belt in pwn.college!
