BlockThreat - Week 24, 2021

Ledger | Clop | Alchemix | Visor | Impossible | BeetsFarm | Iron Finance

Never a dull week in blockchain security! Scammers have really stepped up their game by physically mailing backdoored Ledger hardware wallets, NFT creators targeted with cryptostealer malware, multiple DeFi projects compromised due to design and operational weaknesses, and of course a massive bank run on a stablecoin with weak bad stabilization design wiped out $2B in value.
