An attacker compromised a single admin account managing Hypervisor emergency withdraw functions, enabling extraction of 504,845 USD from unpositioned assets awaiting LP placement. The team had not yet migrated to a multisig setup and the attacker lacked full visibility into safeguards, limiting losses.
The team restored all withdrawn amounts using treasury funds.
