tl;dr https://pastebin.com/raw/qr8XWFkR - you f*cking ping faster than it pongs. this wasn't discovered until recently. sad.

i put this together. it also contains a mode for CVE-2023-33297 ('headers') which was recently patched - although i wasn't given credit because i have haters @ bitcoin-core and blockstream. they kinda run the show now. i'm even banned from contributing to the bitcoin-core github. much decentralization.

how to reproduce the vulnerability yourself:

1. install bitcoin

2. ./bitcoind

3. edit your ip into attack.go: https://pastebin.com/raw/qr8XWFkR

4. save attack.go

5. snap install go --classic

6. go build attack.go

7. ./attack

8. slow oom crash - enjoy the fireworks
