Searching for fix for Rab13s vulnerability (AKA CVE-2023-30769: more here or here) so proudly advertised by Halborn Inc with small funny Halborn did not share the Exploit-kit code with any party comment? :-)
So, here you are! ✌️ You do not need to pay them for any vulnerability disclosure / bug bounty! Just follow my hands 😉 links: from CryptoCurrency's Reddit we go to Litecoin v0.21.2.2 (where LTC Team reports about Important Security Updates under this release @ Mar 2, 2023), and among their 9 commits we can find Rate limit the processing of rumoured addresses (BTW Bitcoin had fixed this issue on Aug 18, 2022 @ #22387 !).
Also:
- Doge (looks like the first one who applied the patch @ Jul 15, 2022 - even early than Bitcoin!),
- Firo (== Zcoin) crypto - they had released v0.14.12.1 Rab13s Fix Release, where we can find net: rate limit the processing of incoming addr messages fix,
- DeFi Blockchain (including some theory).
