A newly whitelisted contract drained over $6 million in wstETH from a Base vault with seven unnamed signers

Security firms traced about 1,783 wstETH, worth more than $6 million, out of a Base vault on Oct. 4 whose owner is an anonymous 3-of-7 Safe. With Base and Aave's core contracts not blamed, the loss lands on a custody setup whose seven signers no one has publicly identified.

Attacker drains up to $310K from two Safes through a leverage module the owners switched on

Two Safe multisigs lost up to $310K after an attacker impersonated a Safe to get past FlashLoopAdapter, an Aave leverage add-on the owners had enabled. Aave and Safe's core code held, so the loss fell on owners who let a module move funds without signatures.

An attacker burned $3.8M in MAMO slippage to borrow $10M of Moonwell depositors' assets

Estimates of the loss run from $4M to $9M against the $72.77M locked in Moonwell, and the remedy was a borrow cap set to 1 wei, which is the tell that this was an underwriting choice rather than a bug.
