v3.0.3 New attack: Secret Size Attack New Category: Interchain, id: 006
v3.0.2
New attacks such as:
Ex Post/Ex Ante Reorg (On-Chain),
Compiler not Optimizing errors (Solidity),
BGP Routing Hijacking (Off-chain) and more.
This work is inspired by attack.mitre.org. Please use attack for "normal" InfoSec/Dev/Sys security check-listing, this is meant to be specialized towards the unique issues brought about in blockchain/cryptocurrency applications (i.e. protocols).
