This week a concerning pattern emerged of DeFi projects failing to implement sufficient function access controls and allowing attackers to trigger functionality used to steal funds. Exchange hot wallet compromises are rare. Unfortunately, Deribit fell victim to bad actors who managed to steal whopping $28M from their hotwallets. Are these our North Korean “friends” again? Another rare exploit vector is the infinite mint which also happened this week with $4.3M stolen from a gaming company.
In other news almost half of Solana validators went offline after they were kicked out by a single hosting provider. The event not only halved security of the network but also could have been much more painful if the chain also implemented inactivity slashing like on Ethereum. Let’s hope AWS doesn’t get mad at the largest staking providers Lido and Coinbase.
