Even Windows has a firewall enabled by default these days. It's not even funny anymore.
Today in #infosec is our first buffer overflow exploit class. I really like this class, watching the newcomers actually exploit the machine to do something unintended and watching them light up in excitement
They have 2 flags to get: one by overwriting %rip to point to another function to jump to it on return, and the other by overwriting a variable value on the stack to trigger alternate code flow paths.
Yes all the mitigations are off. But it's their first exploit.
Fun fact. SNMP MIB database shipped with OpenBSD contains private enterprise numbers for all companies I've ever worked for.

And seeing reviews of the platform, it seems I'm not alone.
I'm in awe in how terrible customer service is despite they're being used as the go-to merchandizing platform of a lot of creators.
I probably won't use this platform again and just suck up the money I paid to this scam.
A shame considering my favorite creators only use this platform.
