The assault concerned flash loans from each dYdX and Uniswap. The hacker loaned greater than $33 million that was used to generate cTokens representing possession in a Compound pool.

The attacker then transferred the cTokens to a Balancer pool. This triggered Compound into distributing the COMP accrued by the pool throughout its regular operation. The hacker then compelled Balancer to replace the pool’s stability, which at this level included the entire flash loaned cash. The system thus believed that the hacker was entitled to a major share of the pool’s COMP, regardless of not having held any cash beforehand.

A name to withdraw the COMP and change it to ETH accomplished the hack, which netted a comparatively small sum of about 10 COMP, value $2,300.

Hao famous that the assault is much like the $500,000 loss from earlier within the day. Like the primary, this second assault depends on the peculiar means that Balancer manages its inner state.

The workforce has since pledged to make affected customers complete. They can even compensate a researcher who reported on the vulnerability in Might.
