DeltaPrime Hack
Reported loss
$6.0M
Private Key Compromised (Unknown Method)
What happened
DeltaPrime Blue's September 2024 exploit drained approximately $6 million from its Arbitrum deployment after an attacker obtained a key controlling contract upgrades. The attacker installed malicious implementations and withdrew deposited assets.
Technical root cause
The compromise of a privileged upgrade key let the attacker replace trusted contract logic. The malicious implementations inherited access to assets held by the affected proxies.
How it happened
- The attacker obtained access to the private key controlling the proxy upgrade administrator.
- They replaced contract implementations with malicious code.
- The replacement code executed with the existing contracts' access to deposited assets, allowing the attacker to drain them.
- The stolen assets were swapped to ETH.
