One industry pundit
This is the second attack on Balancer in less than a month after it warned of a critical vulnerability on Aug. 22, suffering an estimated $2 million exploit related to the vulnerability just days later.
“Balancer is aware of an exploit related to the vulnerability below,” the protocol’s team posted on X on Aug. 27, adding that while mitigation measures taken in recent days had drastically reduced risks, affected pools could not be paused.
“To prevent further exploits, users must withdraw from affected LPs,” it advised.
