A $2M Base vault exploit just turned into a roughly $6M loss.
Blockaid initially flagged an ongoing attack after a newly deployed contract was added to an unnamed vault's whitelist.
The attacker then used that permission to borrow aBaswstETH from the vault and move the assets into an attacker controlled contract.
At first, around $2.02M had been drained across four transactions.
That number later climbed to roughly $6M, with security firms tracking about 1,783 wstETH leaving the vault.
And this is where the story gets interesting.
There is currently no evidence that Base itself was compromised or that Aave's core contracts were exploited.
The bigger issue appears to be the vault's own permission system.
A contract that shouldn't have had access somehow ended up whitelisted, giving the attacker a path to the funds.
Personally, this is the part that worries me more than the headline amount.
DeFi can have battle tested underlying protocols, but if the layer managing access to those protocols gets compromised, the money can still disappear very quickly.
The attack also raises a bigger question around multisig governance and how whitelist changes are approved.
Because “the contract was whitelisted” sounds harmless until you realize that whitelist was effectively the key to millions of dollars.
The investigation is still developing, and the exact reason that contract gained legitimate looking access has not been confirmed.
For me, the lesson isn't that Base or Aave is broken.
It's that the weakest permission layer around a DeFi strategy can matter just as much as the protocol underneath it.
In DeFi, sometimes you don't need to break the vault.
You just need someone to open the door.
